DUKE PLUS MAP EFFECTS
last updated
December 23, 2009 (for version 2.06)
Before attempting to make DP map
effects, you should be familiar with using Mapster
(the map editor that comes with EDuke32). Enough said about that.
Most of the map effects in DP are achieved by placing sprites and setting
various tags on them. In principle it is no different from the BUILD
effects you are already familiar with. The main difference is
that DP uses more than just hitag, lotag, shade and pal, it also requires setting sprite tags
that aren't normally changed (EXTRA, XVEL, YVEL, ZVEL).
Set the EXTRA on a sprite by pressing 'M on the
selected sprite (works in both 2D or 3D modes). Setting XVEL, YVEL and ZVEL is
a little more complicated. First, you must be in 2D mode. Highlight
the sprite so it is flashing, then press F8 on it. This allows you to
edit all of the sprite's properties manually, and you will see that the XVEL,
YVEL and ZVEL are in the right column of editable properties. Setting these
to different values does nothing at all in regular Duke 3D, but in DP they
are used to control various effects.
I have divided the DP map effects into three categories: New Sector Effector Lotags, Duke Plus
Sprites, and Special Tags. The New Sector Effector
Lotags are SE effects exclusive to DP. They use
SE lotags not used by the regular game. The DP
Sprites are specific tiles that have special effects when certain tags are set
on them. Most of these tiles are in the original art files. Special
Tags are used to create effects on just about any sprite in the game (not just
on specific tile numbers).
NEW SECTOR
EFFECTOR LOTAGS
BROADCASTER = SE 88
SHOWS A SCENE FROM A DIFFERENT PART OF THE MAP. THE SCENE IS “BROADCAST” IN THE BACKGROUND, AND IS VISIBLE WHEREVER THERE ARE BLANK TEXTURES (WALLS, FLOORS OR CEILINGS WITH BLANK TEXTURES) NEAR THE SE. PLACE TWO SE88 AND GIVE THEM THE SAME HITAG. ONE WILL BROADCAST THE POV OF THE OTHER.
OPTIONS: GIVE THE SE A YVEL, AND THAT WILL BE ITS ACTIVATION NUMBER, IN WHICH CASE IT WILL NOT BROADCAST UNTIL AN ACTIVATOR OR GAME EFFECT (SUCH AS MONSTER ACTIVATION) TURNS IT ON. MAKE SURE TO HIDE THE BLANK TEXTURES UNTIL THE ACTIVATION USING A SLIDING DOOR OR SOME OTHER TRICK.
THE SE WILL BROADCAST FROM ITS OWN ANGLE. BY DEFAULT, IT WILL USE THE PLAYER’S CURRENT Z ANGLE (LOOK UP/DOWN ANGLE). TO SET A FIXED Z ANGLE, SET EXTRA ON THE SE. 100 = STRAIGHT AHEAD. HIGHER VALUES LOOK UP, LOWER VALUES LOOK DOWN (IN POLYMOST, MAX 299, MIN -199).
TELEPORTER = SE 89
SIMILAR TO THE
OPTIONS: GIVE THE SE A
YVEL, AND THAT WILL BE ITS ACTIVATION NUMBER, IN WHICH CASE IT WILL NOT
TELEPORT UNTIL AN ACTIVATOR OR GAME EFFECT (SUCH AS MONSTER ACTIVATION) TURNS
IT ON. NOTE THAT TWO SE89 WITH THE SAME HITAG COULD HAVE DIFFERENT
ACTIVATION NUMBERS. THIS COULD BE USED TO MAKE A
SET XVEL TO THE SOUND NUMBER TO PLAY UPON TELEPORTATION (LEAVE 0 FOR NO SOUND).
CERTAIN PALS ON THE SE WILL CAUSE A COLORED FLASH WHEN THE PLAYER TELEPORTS: PAL 1=BLUE, PAL2=RED, PAL3=WHITE, PAL4=BLACK, PAL7=YELLOW, PAL8=GREEN. PALS NOT LISTED DO NOTHING.
LOTAG 90 Cutscene camera
This SE can be used to
change the player’s view to the view from the SE. It can be triggered by an event in the game,
or it can occur when the level starts. Cutscene cameras can be either stationary or moving, and
they can be chained together to show a sequence of views. The view can be displayed on the entire
screen, or it can be displayed in a box in the corner. By default, the player is paralyzed while
this effect is ongoing. Tags on the SE
control different aspects of the effect:
Hitag: Set to 0
to switch to the SE view at level start.
Otherwise, hitag is the activation
number. The SE can be activated by an
activator having a lotag equal to the SE’s hitag, or by a switch, monster, or other DP sprite which
has a YVEL equal to the SE’s hitag. The player will view from the SE immediately
upon activation.
Pal: 0 = stationary
camera, 1 = moving camera. A moving
camera will not work unless there is another SE 90 which has a hitag equal to the YVEL of the moving camera.
Shade: The up/down view angle. 0 looks straight ahead, negative numbers look
up and positive numbers look down. The
exact formula is camerahoriz = shade*2 +100
XVEL: In a stationary camera, this is the number of
game tics that the camera’s view will last. In a moving camera, XVEL is the speed at
which the camera travels. If not set,
XVEL will default to 130 (five seconds of view time for a stationary camera,
and about ½ of
Duke’s running speed for a moving camera).
YVEL: This is the number that the camera activates
upon completion. In a stationary camera,
completion occurs when its time runs out.
In a moving camera, completion occurs when it has traveled all the way
to the next camera in the sequence. The
camera will activate any respawns, activators, masterswitches, or DP sprites which have activation numbers
equal to the camera’s YVEL. This
includes other cutscene cameras. If the camera is
stationary, it does not have to be set to activate anything. If it is a moving camera, it must be set to
activate another SE 90 (see Pal, above).
ANG: The angle of the SE sprite will be the angle
that the camera faces. If it is a moving
camera, then it will start at this angle and gradually turn to face the angle
that the next camera is facing.
EXTRA: This is a bitfield
which determines some additional camera functions. Add together the numbers you want, or leave
EXTRA at its default value (-1) if you don’t want any of the options.
1
does a quick
fade to black right before the camera’s view time ends (does not work
with moving cameras)
2
shows the
view in a box in the lower right corner of the screen (the rest of the
player’s view is normal)
4 if
this bit is set, the player will be moved to the camera’s position.
8 allow the player to move (best used in
combination with 2)
16 transition effect: when camera
activates, its view starts in the center and quickly expands to fill the screen
(do not use with 2)
LOTAG 102 Transparent water sector
THE BASIC EFFECT:
Place a SE with lotag 102 at the height that
you want the water surface to be. Any sprite that goes below that height
in the sector will be underwater. If the sector is going to be entirely
underwater, you should set the EXTRA of the SECTOREFFECTOR to 1 (this will ensure
that anything in that sector is considered underwater, regardless of the height
of the effector sprite). To
complete the effect, place some flat WATERTILE2 or 889 sprites at the water
level and make them transparent and non-blocking (see sample maps for examples).
An underwater player will be able to see out of the water from below, and vice
versa.
WATER COLOR AND
FOG: To change the appearance of the water, change the pal of the lotag 102 SE.
Pal 0 =
normal water, no fog,
Pal 27
= red liquid,
Pal 28 =
green liquid
Pal 29 = blue
liquid
Pal 30 =
normal water with fog
Pal 31 = dark
water with fog
Pal 32 = very
dark water with fog.
In addition, the
shade of the SE alters the visibility of the underwater area (higher shade =
less visibility, shade 127 is the maximum).
WATER WITH A
CURRENT: To make water with a current, set the XVEL of the SE to the
desired speed (96 is about the speed that the player can swim). The water will
move in the direction that the SE is facing.
BOBBING
WATER: To make water that is able to rise and fall, you must place a red
H sprite (tile 2947) in the sector and give the H sprite a lotag
of 1. The H should be
placed at the same height as the SE. The hitag
of the H will determine how far up and down the water moves (it will move 8 z
units for every 1 hitag, so a hitag
of 1000 will make if move about one player body length), and the ZVEL of the H deterimines how fast the water moves (numbers < 1000 are
best).
WATER THAT RISES
OR FALLS ON SWITCH ACTIVATION: To make water that rises/falls in response
to a switch, set the YVEL of the SE (or however many SEs
you want controlled) to some number that is not
being used as a lotag for any other effects. Then
place a switch and set the YVEL and lotag of the
switch to that number. The height that the water will end up at after the
switch is thrown will be the height of the H sprite that you placed (which
could be either higher or lower than the water SE). If the switch is
activated again, the water will move back to its original position. To
prevent this, set the hitag on the SE to 1, and the
water will only move once.
LOTAG 104 FLOOR AND CEILING
TEXTURE PANNING
Set the SE to lotag 104. XVEL of the SE determines the x panning
speed (can be positive or negative). YVEL determines y panning
speed. Leave ZVEL at 0 if you want only the floor to pan. Set ZVEL
to 1 if you want only the ceiling to pan. Set ZVEL to 2 if you want both
the floor and ceiling to pan. Note that different sectors may
automatically pan in different directions -- this seems to be determined by the
direction that the firstwall of the sector is facing.
LOTAG
105 SLEEPING EFFECT
This effect will
make the screen fade to black and freeze the player in place when he enters the
sector. The screen will then fade back in with the player in a new location.
To make the effect, place two lotag 105 SEs in different sectors, and give them each the same hitag. When the player reaches one of these, he will
"sleep" and then wake up at the other one, facing the angle of the
destination SE.
Additional
options:
Fade colors
(set on both SEs)
Pal 1 –
fade to blue
Pal 2 –
fade to red
Pal 3 or 13
– fade to white
Pal 4 –
fade to black (default, same as pal 0)
Pal 8 –
fade to green
Set EXTRA on
the SE as a bitfield (add the desired values
together)
1 – set on destination SE to take away all of the player's
weapons and inventory.
2 – set on origin SE to lock the player’s view to straight
forward position when effect begins
4 – set on destination SE to lock the player’s view to
straight forward position as player is waking up
8 – set on origin SE to make the effect work only if the player
presses the use key with an angle opposite of the SE angle
Set XVEL on
the SE if you want a longer delay before the player falls asleep (XVEL 26 = 1
second).
Set YVEL on
the SE to the sound you want it to play when the effect begins (0 means no
sound; sorry, you can’t play KICK_HIT)
If you set
ZVEL on the SE, then it will be destination only (the player will be able to move through the sector without sleeping,
but he can be taken there by another SE).
LOTAG 107
TRANSITION EFFECT
This effect is
just like the sleeping effect (see above), but it can be used more than once.
If the player reenters the destination sector, he will be taken back to
the origin sector, and vice versa. The transition effect has the same pal
EXTRA options as the sleeping effect (see above). The XVEL option is different and controls the
speed of the transition:
XVEL -1 slow
(about 10 seconds total)
XVEL 0 default
(about 5 seconds total)
XVEL 1 faster
(about 3.3 seconds total)
XVEL 2 about 2.5
seconds total
XVEL 3 about 2
seconds
…and so on
Set YVEL on the
SE to the sound you want it to play when the effect begins (0 means no sound;
sorry, you can’t play KICK_HIT)
LOTAGS 116
AND 118 ELEVATORS WITH MORE THAN TWO
STOPPING POINTS
INSTRUCTIONS:
(1)Place a
SECTOREFFECTOR in the elevator sector. Give it a lotag
of 116 if you want only the floor of the elevator sector to move, and give it a
lotag of 118 if you want the ceiling to move as
well.
(2)Set the hitag of the SE to the number of the sound you want it to
play when the elevator is activated (#71 is the standard sound).
(3)The shade
of the SE is the number of different stops the elevator will make. You
probably want the shade to be 3 or higher, since otherwise there is no point in
using this effect (the elevator will not function at all if shade is less than
2).
(4)The XVEL
of the SE determines the distance the elevator travels between stops. The
higher the number, the greater the distance: XVEL * 64 = Z units.
This means if you want the elevator to move 32768 Z units between floors (or
about three times the player’s height), set XVEL to 512.
(5)The ZVEL
of the SE determines the elevator’s speed and initial direction. If
ZVEL is negative, the elevator’s initial position in the map editor will
be its highest point; if ZVEL is positive the start position is the lowest
point. Magnitudes between 256 and 1024 will serve for most
purposes. For example, a ZVEL of -1024 means that the elevator starts in
the up position and will move pretty quickly between stopping
points when activated. IF YOU DON'T WANT THE ELEVATOR TO BE ACTIVATED
BY A SWITCH, THEN YOU ARE DONE.
(6)There are
two ways to set up elevator operation: operation via the open key, and
operation via switches. If you do nothing further, the elevator will be
operated by the open key. The disadvantage to the open key method is
there is no way to control whether the elevator goes up or down – it must
be cycled through all of its positions. Thus, you will probably want to
make the elevator operated by switches. To do this, start by assigning a
nonzero YVEL to the SE.
(7)Next,
place two switch sprites (any of the switch tiles should work). Assign
one lotag to the switch that will move the elevator
up, and a different lotag to the switch that will
move it down. In addition to the normal switches, you can use the Duke Plus buttons with animated up and down arrows. The
down switch is tile 8032, the up switch is 8037. These function just like
the normal switches, except that you don’t have to set a lotag on them.
(8)Now
assign both switches the same YVEL that you assigned to the elevator SE. The
YVEL does not need to equal either of the lotag
values you gave the switches.
(9)Finally,
assign one and only one of the switches an XVEL of 1 – that will make it
move the elevator in the opposite direction from the other switch. At
this point, your elevator should be operational. Test it in game to see
which switch moves it up and which moves it down (you can then reverse the
switches by trading their XVEL values, if necessary). You can make
another pair of switches for the same elevator. Give the new pair of
switches the same lotags as the first pair, and the
same YVEL, and make sure one has XVEL of 0 while the other has XVEL of 1.
The switches can be placed inside of the elevator and they will move along with
it. For best results, use the DP elevator buttons mentioned above.
LOTAG 666
SECTOR OF DEATH
Place an SE and
give it a lotag of 666, and any actor killable actor
(player, monster, etc.) that falls below the SE in that sector will be
annihilated. Useful in multiplayer maps, if you want players to die in a
certain area, but don't want to make them fall a great height. If you want the
SE to only kill in a certain zone below it (it kills things below it, but only
up to a certain distance), then set its ZVEL to the desired distance of death.
The distance you set is multiplied by 8 -- e.g. set ZVEL to 1024 and anything
up to 8192 build z units below the SE in that sector will be killed.
Duke
Plus Sprites
The following
effects are created by sprites other than SEs.
Except for the monsters, they are listed in tile number order.
Customizable Monsters
Keycards are
a special case:
Set XVEL to
60 and the monster will drop a pal 0 ACCESSCARD.
For a pal 21
ACCESSCARD, use an XVEL of 62
For a pal 23
ACCESSCARD, use an XVEL of 63

*If bits 2 and 4 are both set, then the monster will
have x6 normal hit points.
**Increasing attack power will have different effects
depending on the monster. On a Sentry Drone, for example, this bit will cause its
explosion to do double damage. On other monsters, it will cause the monster to
fire two shots instead of one. In some monsters, the monster will fire one shot
for double the normal damage. Sharks with increased attack power will become
killer sharks and will behave differently from normal sharks.
***The monster will sometimes try to teleport behind its
target if the target is facing it. This is more likely to happen in open
spaces. If the monster cannot find a good spot to teleport to, it will not teleport.
****On NEWBEAST, this flag will cause it to use only is
claws to attack. On LIZTROOP, this flag will make it a suicide bomber:
it will rarely shoot, and will detonate itself when close to an enemy.
On ROTATEGUN, this flags will make it shoot at double the normal rate.
On PIGCOP, it will give the pig a double-barreled shotgun.
*****The monster will try to back away from the player
if the player is in sight, but it will keep shooting.
******This can be used as a substitute for STAYPUT type
monsters – the monster can still walk around but will not walk off
ledges. DO
Examples: Press 'M on a PIGCOP sprite in mapster and set the EXTRA of a PIGCOP to 10 (2+8), and it
will have double hit points and double attack power. A LIZTROOP with an EXTRA
of 196 (4+64+128) will have x4 hit points, shoot railgun
shots, and be able to teleport.

ELECTRONET
-- An electrical net that spawns lightning bolts on impact.
FIREBALL
-- A slow moving fireball that tracks the player, can
be shot out of the air with hitscan weapons.
RAILGUN
-- A railgun shot.
Breakable glass pane sprites.
Place a GLASS
sprite (tile #503) and give it a lotag of
1. In game, the first hit from a weapon will crack the glass, and the
second will shatter it. (Though the first hit can shatter it if it does
enough damage). Rockets can break through the
glass and keep going. Glass sprites can be linked by hitag,
if the hitag is greater than 0. For example, if
you place four glass sprites and give them all a hitag
of 1, damaging one will cause all of them to be damaged. This is useful
if you want to create a large pane of glass without stretching the sprites.
Invisible Blocking Sprites
Place a sprite of tile #507 and give it a lotag of 1. In game, the sprite will be invisible and
blocking, but allow hitscan (bullets) to pass through
it. Useful for constructing barriers to prevent the
player from entering certain areas without adding walls to the map.
Cracks
with more activation abilities
Set the YVEL of
any of the crack sprites (CRACK1, CRACK2, CRACK3, CRACK4)
to a tag number that is to be activated when the crack is destroyed. It should cause all
activators, masterswitches and respawns
with that tag to work.
Rain
and Snow in outdoor areas.
Place a WATERDRIP
sprite (tile #660) somewhere in the map. Then, change the EXTRA tag of
the sprite to a nonzero value between -32 and 32 (positive values for rain,
negative for snow). The greater the magnitude of this value,
the greater the density of the rain or snow. The rain or snow will have
the palette and transparency level of the WATERDRIP sprite. You should only
place one such sprite in the map (you can place other WATERDRIP sprites, but
only set EXTRA on one of them).
You may want it
to rain/snow in some outdoor areas but not others. To prevent rain/snow from spawning in a
sector, give the sector a hitag of 101.
This is also useful if the sector has a parallaxed
ceiling but is not outdoors.
Flying helicopters that drop stuff.
Place the second
helicopter tile (tile #1338) and set its lotag to the number of things it will spawn (this must be
higher than 0 or it will not work at all). Set hitag
to the number of ticks it will travel before dropping the spawned items.
Set XVEL to the tile number that it will drop (only one tile number per
helicopter). This could be the tile number of a monster, item, or
anything else. Set EXTRA to the flag value that the
spawned sprites will have (useful if it spawns Dukebots
or monsters). Spawned sprites will have the same pal as the
helicopter as well. Set ZVEL to the quote number that will be displayed
when the drop occurs (leave this value at 0 to display no quote). Last
but not least, set YVEL to the activation number of the helicopter. It
can be activated by an ACTIVATOR or ACTIVATORLOCKED, or any DP sprite that uses
activation and has its YVEL set to that number. For example, you could
activate the helicopter with a DPTOUCHPLATE that has a
YVEL set to the YVEL of the helicopter (but not a regular TOUCHPLATE).
Once activated, the helicopter will appear and will move at a slow speed
that is not adjustable, and it will move in a straight line until it is unable
to move, at which time it will disappear. The angle it will move at is
512 build degrees clockwise of the angle of the sprite (this was necessary
because the original sprite is facing sideways).
DukeBots (1431)
WAYPOINT BASICS:
A bot will follow a path only if 256 has
been added to its EXTRA in Mapster (setting EXTRA on
a RESPAWN or SPAWNER that spawns the bot has the same
effect). A bot trail is made of of WAYPOINT sprites (tile # 1490 in the Duke Plus
tiles05.art). The first WAYPOINT must be given a lotag
of 1 (NOT 0!), and they must be placed in sequence with ascending lotags. The path can be made to loop -- in that case,
make sure that the first WAYPOINT in the path is accessible from the final
waypoint in the path (just as you would do with a RECON path). Instead of
being a loop, the path can be made to end by adding 1 to the EXTRA of a
WAYPOINT. Once a bot reaches a WAYPOINT that
has 1 as part of the EXTRA bitfield, it will stop
following waypoints and resume its normal behavior of attempting to follow the
player.
ADVANCED USES
OF WAYPOINTS:
If YVEL is
set on a WAYPOINT sprite, then the first bot who
reaches that WAYPOINT will activate any ACTIVATOR, ACTIVATORLOCKED,
MASTERSWITCH, RESPAWN, SPAWNER, FUSE or SE that is triggered by that tag.
This can be used to make a bot open a locked
door, etc.
If ZVEL is
set on a WAYPOINT, then a bot who reaches it will
stop and wait there. He will not move from that spot (except to fight
monsters) unless the WAYPOINT has been activated by a switch, SPAWNER or
DPTOUCHPLATE that has a YVEL equal to the ZVEL of the
WAYPOINT. This is useful, for example, if you want a bot
to wait patiently at a door until the player unlocks it, and
then continue on his path.
If
1024 is added to the EXTRA of a bot (and is used in
combination with 256), then the bot will be in lead
player mode. When in
leading mode and on a path, the bot will
automatically stop to wait for the player if the player is not close to him.
To disable this feature only on certain WAYPOINTs,
add 2 to the EXTRA of those WAYPOINTs. This is
useful if, for example, you want the bot to start on
his path when he is still far away from the player, but then you want him to
lead the player when he reaches a certain area.
In addition to
the BOT ASSISTANCE option, bots can be placed directly in a map. Place a
BOTALLY (tile 1431) in the map and give it a lotag of
1. Then determine its attributes by setting its EXTRA ('M on the sprite in mapster to set EXTRA). As with monsters (see below), this acts as a bitfield:

Add together the bits that you want to get the desired
effects. For example, a BOTALLY with an EXTRA set to 26 (16 + 8 + 2 ) will be a medic with double strength and a shotgun.
Breakable
Chains
The chain sprite (tile# 920) can be made breakable by hitscan weapons (bullets).
To do this, give it a lotag of 1. You can also make the chain activate
something when it is destroyed. Set YVEL
to the activation number. It will activate ACTIVATOR, ACTIVATORLOCKED,
MASTERSWITCH, RESPAWN, and various DP sprites.
Coronas
To add a corona
to an object (such as a street light) place either a tile 1632, 1633
or 1634 where you want the corona to be, and give the sprite a lotag of 1. In game, the corona will be transparent and
will change size depending on the distance from the player. By default, a
corona has a minimum size of 12 (xrepeat/yrepeat). If
you want the minimum size to be different, set the hitag
of the sprite to the desired minimum.
DUKE
PLUS TOUCHPLATES.
To make a
DPTOUCHPLATE, place a red A sprite (tile #2940)
and give it a lotag of 1. Set YVEL on
the DPTOUCHPLATE to the tag number that you want it to activate (just like
you would set lotag on a normal TOUCHPLATE). It
will activate ACTIVATOR, ACTIVATORLOCKED, MASTERSWITCH, RESPAWN, and various DP
sprites. DPTOUCHPLATEs are useful for two
reasons: 1) it is more compatible with DP effects than a regular
TOUCHPLATE. For example, DPTOUCHPLATE can
activate a WAYPOINT (see section on bot allies in DPdoc) while a regular TOUCHPLATE cannot. 2) the DPTOUCHPLATE can be made to be triggered only when the
player is below it, instead of triggering the moment the player enters its
sector. For this feature, give the DPTOUCHPLATE an EXTRA of 1. This
is useful if you want the player to be at or near the ground when the
activation occurs, instead of just anywhere in the sector. Finally, a DPTOUCHPLATE can be made
dormant. To do this, set its XVEL to an
activation number. Once set, the
DPTOUCHPLATE will do nothing when the player enters its sector until that
number has been activated.
Dynamic
Lights
In Duke Plus, a
“dynamic” light is a light source that can move and has various
adjustable properties, similar to the Duke Plus flares. Because dynamic
lights can impact performance, it is not recommended that they be used as a
substitute for normal map shading and lighting effects. They should be
used sparingly, and only to do things that would not otherwise be
possible. For example, you could place a dynamic light on a moving
sector, and it would cause nearby areas to light up as the moving sector passed
by. You could also make an ordinary destructible sprite (such as a
monster or a breakable object) into a light source.
MAPSTER
INSTRUCTIONS: Place a red D sprite (tile #2943) where you want the
light to be. Give it a lotag of 1. Give
it a hitag corresponding to the picnum
that you want it to become when the map loads (for example, if you give it a hitag of 2000, then it will be a PIGCOP that is also a
light source). Next, set the YVEL of the sprite to the intensity of the
light (values between 30 and 200 are good for
most purposes). Finally, set the ZVEL of the sprite if you want the light
to flicker (1-100). The size and pal of the sprite will be preserved when
it changes picnum.
How Duke Plus
lighting works: To use DP lighting effectively, it is helpful to
know how it works. First of all, if the lighting system is going to be used,
then it is initialized when the map loads. This entails that a new sprite
be spawned for each lightable sector (normally, each
sector in the map). A map with 2000 sectors would then contain 2000
additional sprites when the game is started (something to keep in mind if your
map already has a lot of sprites). What do all of these sprites do?
The sprites are light controllers, and each one is responsible for
dynamically changing the shading of its sector depending on the position and
intensity of the light sources in the map. The light controllers must
also remember how the sector is shaded when no dynamic lights are affecting it,
so that they can restore normal shading when a DP light is no longer around; this is actually quite tricky, because many sectors
do not have static shading to begin with -- they may contain light switches,
cyclers, etc. As a mapper, there are two things
you need to keep in mind. First, because the light system is sector
based, you cannot get a very realistic effect without using relatively small
and regular shaped sectors. Second, because of the number of sectors involved
and because of all of the math that the light
controllers have to do, the DP lighting system can adversely affect
performance. Take a look at how the effect is used in the DPEFFECTS.MAP
for a good example of its proper use.
NOTE: The
sector based dynamic lighting described above will soon be phased out in favor
of true dynamic lighting using the new renderer, polymer.
Gust
Spawner
This creates the
effect of small clouds or smoke puffs blowing past. It could be used to make a
map that takes place inside of a moving airplane, with the clouds visible
through the windows, or it could be used to add atmosphere to any map. The
effect is created by placing tile #2946 (the red 'G') and giving it a lotag of 1. The size of the sprite will determine the size
of the smoke puffs that it spawns. Pal and shade are transferred to the spawned
smoke as well. The puffs will move in the direction that the sprite is facing,
and disappear when they hit a wall. The hitag of the
sprite is the number of ticks between spawns (26 = one second). The XVEL of the
sprite determines the speed at which the smoke will move: valid numbers are
between 1 and 100. If you want the smoke clouds to disappear before they
hit a wall, set YVEL on the spawner to the number of
ticks that the smoke clouds will last.
Jump
Pads
To make a jump pad,
place a sprite #2949 (the red 'J') in the map, and give it a lotag of 1. The hitag of the
sprite will determine the activation distance (if you leave hitag
at 0, it will activate when the player gets within 640 BUILD units). The XVEL
of the sprite will determine the horizontal velocity of the player when he is
jumped by the pad (values between 128 and 1024 are good in most cases). The
YVEL of the sprite will determine for how long, in ticks, the jump from the pad
will exert a force on the player while he is airborne. If you leave YVEL at 0,
it will default to 26 ticks (1 second). It is important to set YVEL to
the correct number; if it is too low, the player will not reach the intended
destination. The ZVEL of the sprite is the most important and delicate
setting; it determines the vertical velocity of the player's jump. Depending on
the desired height, this will probably be a value between 512 and 2048. The
angle of the sprite will determine the direction that the player moves in (of
course, if XVEL is very low, then this won't matter). Finally, set the
EXTRA of the jump pad sprite to 1, and it will emit energy pulses showing the
trajectory that the player will follow.
Sparker
A sparker will periodically
spawn sparks and make random short-circuit sounds. To make a sparker,
place a tile #2950 (the red 'K') and give it a lotag
of 1. Give it a hitag for the delay, in ticks,
between sparks (the delay will still be random, but the higher the number the
longer the delay).
Ladders
USING LADDERS IN
GAME:
Approach the
ladder and press forward while facing the general direction of the ladder to go
up. Move backwards to come down. You can also grab on
to a ladder by jumping to it. If you are at the top of the ladder, you must
move backwards, with your back to the ladder, to get on it. Crouching while
moving backwards is safe, as is walking, but if you run backwards you will
usually miss. Once on the ladder, you can stop any time. But if you turn around
too much, you will fall off. If you hold the jump key while on a ladder, you
will slide down.
MAKING LADDERS
IN MAPSTER:
To make a
ladder, you need to place two sprites of tile number 2951 (the letter
'L' in the red font). If these are tagged as ladders, they will become
invisible once the game starts.
Set the EXTRA of
each sprite to 1, and make sure the pair of sprites has the same hitag.
Place one of the
sprites above the other. The higher sprite will be the top of the ladder, the
lower sprite the base of the ladder. Make sure that the ladder top is where you
want Duke to get off the ladder. That means it must be almost a full Duke
height above the ledge, or else Duke will simply fall back down when reaching
the top of the ladder. Of course, the graphics you use to represent the ladder
do not need to extend above the ledge, only the special sprite defining the
ladder top does.
If you want a
sound to play while the player is going up and down the ladder, set the lotag of the base ladder sprite to the number of the sound
you want played. The vent crawling sound is a good choice.
Additional
notes: The x and y
coordinates of the base of the ladder will determine the ladder's actual
position (the sprite for the top of the ladder is only referenced for its z coordinate,
so technically it doesn't matter where you put it, as long as it is above the
base). That means that ladders are strictly up and down affairs and cannot be
sloped. The angle of the base of the ladder determines the angle that the
player is supposed to face when using the ladder. So, if the ladder is up
against a wall, then point the ladder sprites at the wall.
Movement Option
Controller
If this sprite is placed, then the player will have
the movement options specified when playing the map, and will not be able to
change them in-game using the menu. This is useful if you have designed
your map for ledge grabbing, or you don't want the player to have dodge jumps,
etc. Place the red 'M' (tile #2952) and give it a lotag of 1. Next, set the EXTRA on the sprite to the
desired movement options. EXTRA on this sprite functions as a bitfield, so you add together the values for the different
movements:
1 = realistic running acceleration on
2 = mantling (ledge grabbing) on
4 = dodge moves and wall jumping on
8 = player can pick up and throw objects
16 = turns off
Duke’s extra lip movement (blocks the Duke Taunts Plus option)
Add together the numbers corresponding to the options you want for the map. For example, if you want
mantling and object grabbing, but not realistic running or dodging, then you
would set EXTRA to 12. If you do not place this sprite, the player will
have whatever moves he has selected in the Duke Plus menu.
Model and/or
Model Animation Disabling
In Duke Plus there is a special sprite that can disable model rendering or
model animation on specified tile numbers. This is useful if you have a
certain sprite in your map that does not animate in 8-bit mode, but when used
with the HRP is replaced by a model with animation. You can specify that
certain tile numbers will not have animation, and you can also specify that
certain tile numbers will not be replaced by models at all (they will remain as
sprites). To do this, place a sprite of tile # 2953 (the red 'N')
in your map and give it a lotag of 1. To make
the sprite disable models, set the hitag, XVEL, YVEL,
ZVEL and EXTRA to the tile numbers that you want to disable
(each model disabling sprite can disable up to 5 different tile
numbers). For example, if you wanted to disable models on tile
2002, you could set the hitag of the sprite to 2002
(say, if you wanted to use a pigcop tile as flat
piece of art, and didn't want the pigcop model
walking in the painting). If you also wanted to disable 2003 and 2004,
you could set the XVEL and YVEL of that sprite to those values. To allow
the tile to be rendered as a model but disable its animation, set the pal of
the disabling sprite to 1.
Noise
Place
Temp Sprite
Temp sprites are visual props that can be made to appear upon activation, and then later disappear with another activation. These are useful for making areas that change appearance after certain events. All temp sprites are tile number 2955 (the red P). They become invisible when the map loads, and upon activation they change to look like another tile specified by the mapper. Note that these are not like RESPAWN; they do not spawn another tile, they just look like it. This is important to remember, because they will not run any of the code specific to the tiles they are made to look like (for example, they will not take damage if you shoot them). Also, they may not block like the other tile because tile 2955 is very small (so, for example, it would be inadvisable to use the effect to make s sprite bridge appear, unless it is purely decorative and the player never has to walk on it).
HITAG: This is the activation number that makes the temp sprite visible. Hitag 0 temp sprites are visible when the game starts.
LOTAG: This is the activation number that makes the temp sprite die (note that it cannot die unless it has been activated first).
EXTRA: This is the tile number that the temp sprite looks like when it has been activated. Note that it will not display animation unless the animation is defined on the tile in an .art file or a def file.
When temp sprites become visible, they retain the cstat, pal, angle, xrepeat and yrepeat given them in the map.
Quoter Sprite
A Quoter sprite will display
a quote or picture of your choice when the player enters its sector.
Place a sprite of tile #2956 (the red "Q"). Give
it a lotag of 1 if you want it to display a quote
using your own customized settings for size, positions, etc. Give it a lotag of 2 if you want to display a picture. Give it
a lotag of 3 to display a quote using the standard
Duke 3D quote system (at the top of the screen in white text for five seconds,
or until another quote is displayed). Set the hitag
to the number of the quote you want displayed, or to the tile number you want
displayed if the quoter has lotag
2. If you use lotag 3, then no other settings
are required. Otherwise: EXTRA is the number of ticks that the
quote or picture is displayed. XVEL and YVEL are the X and Y coordinate
offsets, which can be postive or negative. Leave
XVEL at 0 on lotag 1 Quoters
and the quote will be centered. ZVEL is the size offset. Note
that the values needed for X and Y offsets will change depending on the size,
and are different for quotes and pictures. The quote or picture displayed
will have the pal and transparency of the quoter
sprite. A quote and a picture can be displayed at the same time, but this
requires two different sprites.
Spawner
A Duke Plus Spawner is
similar to a RESPAWN sprite, but with many more options. Once activated,
a spawner will periodically spawn a sprite of a
certain tile (such as a monster) a certain number of times. Upon spawning the last
one, it can operate activators, masterswitches and respawns if you desire. It is highly customizable.
Mapster instructions:
Place a sprite of tile number 2958
(the red S). In game, the Spawner can be
activated in three ways. If you give the Spawner a lotag of -1, it will activate as soon as it can
"see" the player (just like a monster). With a lotag of 1, it will activate when the player enters its
sector. If the Spawner has a lotag higher than 1, then it will be triggered by an
ACTIVATOR, ACTIVATORLOCKED, DUKE PLUS TOUCHPLATE or other DP activation with a
YVEL equal to that lotag. If you leave
the lotag at 0, it will not work at all.
Now that you
have set the lotag, set the hitag
to the tile number of the sprite (e.g. 2000 for PIGCOP) you want it to spawn.
Set its shade to the total number of sprites you want it to spawn, or set the
shade to a negative value to spawn without end. Setting its
pal lower than 26 will make the spawned sprites have that pal. If
pal is 26 or higher, then it acts as a delay (in number of ticks) until the
first sprite is spawned (this is not the same as the delay between spawns). If
the spawned sprites are monsters, you can set the XVEL of the spawner to the tile number of something you want the
monsters to spawn when they die (just like you would set it on individual
monsters). Normally, spawned sprites use the TRANSPORTERSTAR effect when
they spawn in, but you can disable this by setting XVEL on the spawner to -1 (useful if you are spawning something that
isn't a monster, such as TRASH). You can also set the EXTRA on the Spawner to set the monster flags of the spawned monsters
(again, just like you would set it on the monster sprites). Set ZVEL to the
number of ticks in between spawns (130 would be five seconds). Finally, set
YVEL if you want it to operate activators and master switches when the last
sprite is spawned (YVEL = the lotag it activates).
A spawner can made to spawn jibs,
but you must use one of the following hitags:
2246 // spine
2251 // eyeball
2256 // heart
2261 // intestines
2266 // ribs
Shooter
A Duke Plus Shooter will periodically fire a
projectile of your choice, with various options. The Shooter sprite is
invisible in-game and indestructible (unless set otherwise). Place tile #2959
(the red T) and give it a lotag of 1 or higher.
Lotag 1 is for activation on sight, 2 or higher
is an activation number (set it off with an activator DPTOUCHPLATE, etc.)
Hitag is the tile number of the projectile it
shoots (see below for complete list). Set shade to the total number of
shots you want it to fire, or -1 to make it fire forever.
EXTRA is a bitfield that determines how it aims (add
the desired numbers together):
-1 or 0 means it
always fires where it is initally pointed,
2 = aims at player and player allies
4 = aims at bad guys
8 = trajectory of projectiles is slightly
random.
16 = timing of the shots
is moderately random (you still use ZVEL to determine the basic timing)
32 = makes a sound when
it fires (the sound is appropriate to the projectile)
64 = destroyed by
explosives
256 = projectiles do not emit dynamic light
ZVEL
is the number of ticks between shots (higher numbers = lower rate of fire).
Finally, YVEL is the vertical component of its aim (used only if it does
not aim at friends or enemies). Positive values make it aim down,
negative up.

Weapon Options Controller
If this sprite is placed, then the player will have the weapon
options specified when playing the map, and will not be able to change them
in-game using the. This is useful if you have designed your map for the
gravity gun, etc. Place the red 'W' (tile #2962) and give it a lotag of 1. Next, set the EXTRA on the sprite to the
desired weapon options. EXTRA on this sprite functions as a bitfield, so you add together the values for the different
movements:
1 = akimbo pistols
2 = Cruizer shotgun
4 = MP5 sub-machine gun
8 = heavy rocket launcher
16 = mind blast alt-shrinker
32 = karate kicks
64 = gravity gun replaces expander
128 = dukemon capsules replace tripbombs
256 = freezer plus
512 = BFG replaces devastator
Add together the numbers corresponding to the weapon options you set for the
map. f you do not place this sprite, the player will
have whatever weapon options he has selected in the Duke Plus menu.
INVENTORY OPTIONS
CONTROLLER
If this sprite is placed, then the player
will have the inventory options specified when playing the map, and will not be
able to change them in-game using the Place tile #2948 and give it a lotag of 1. Next, set the EXTRA on the sprite to the
desired inventory options. EXTRA on this sprite functions as a bitfield, so you add together the values for the different
options:
1 health items can be stored in medkit
2 holoduke spawns bot
4 enhanced steroids
8 goggles show dipswitch patterns
16 enhanced armor
32 double-jump can start jetpack
Boxes
that can be picked up, dropped, thrown, piled and stood on
The small box
(not so small, really) is tile 6314 and the big box is tile 6316 Pal
0 is the metal version and pal 30 is the wood version. Press use to pick up a
small box: then press fire to throw it or press use again to place it. The
large boxes cannot be picked up, but they can be pushed (press use while pressing
forward against the large box).
Fuses
Duke Plus fuses (tile #6319) are a
special actor that can be picked up and carried, then placed in designated
spots in order to trigger activators, masterswitches,
or respawns. In some respects they are similar
to ACCESSCARDs. The main difference is that
fuses can be set up so that several of them have to be placed before an effect
occurs. For example, you could make a fuse box that has four missing
fuses, and the player has to find and place four fuses in order to return power
to an area.
How fuses work: First, decide where the player is supposed to insert the
fuse sprites (make a fuse box in a wall or some
other suitable destination). At the places where the
fuses are to be inserted, place fuse sprites. Make them look just
the way you want them to look after the player has placed them. Give them
all a lotag of 1 (this tells the game that the
sprites are functional and not just
decorations). Now, give these destination fuses an EXTRA of 1. This
will designate them as destination points and make them invisible in the game
(the fuses that the player actually picks up and places are different sprites).
Next, make sure that all of the destination fuses that are part of the
same group share the same hitag, which must be less
than 10 (the only time you would need to set hitag is
if there is more than one group of fuses in your map; otherwise, you can leave hitag at 0). The point of the fuses is to activate
something; to make them do this you must set YVEL on all of the destination
fuses to the tag number that you want them to activate. For example, if
you set YVEL on the destination fuses to 13, then once the fuses are placed,
any ACTIVATOR, ACTIVATORLOCKED, MASTERSWITCH or RESPAWN of lotag
13 will activated. There is one more thing you need to do to prepare the
destination fuses, and that is to tell the game how many different fuses must
be placed to cause the activation. Do this by setting XVEL on each
destination fuse in the group to the total number of fuses that need to be
placed. For example, if there are 4 fuses in a group (4 sharing a hitag), and the player must fill each of the 4 destination
sockets to cause the activation, then you would set the XVEL of each
destination fuse to 4. On the other hand, you could set the XVEL to 3,
and this would mean that only 3 out of 4 sockets need be filled to cause the
activation. (If you set XVEL to 5, that would
make the activation impossible). Now that the destination points are set
up, it is time to place the fuses that the player actually sees in the game and
picks up. For the pick up fuses, all you have to do is place the sprites
(same tile # as before) give them a lotag of 1, and
if applicable give them the hitag corresponding to
the fuse group. Do NOT set EXTRA on the pick up fuses, and you do not
need to set YVEL. With this done, the player will be able to pick up the
fuses in-game and place them in the "sockets" defined by the
destination fuses you set up earlier.
Fireflies
These small
glowing balls float around randomly and can add atmosphere to a map. Place a
tile 4884 in the map and give it a lotag of 1,
and it will become a firefly when the game starts (it will automatically be
resized). They work well with different palettes.
DP Cannon
This is an old-fashioned cannon which can be controlled by the
player. It is tile # 6172.
It does not require any special tags to work. As an option, you can limit its turning
radius. Set EXTRA to the number of
degrees (in BUILD units) it is able to turn.
For example, if you set EXTRA to 512 (which equals 90
real degrees), then the cannon will be able to swing 90 degrees in either
direction. In game, the player
takes control of the cannon by getting behind it and pressing the open
key. It has an unlimited number of
shots. The cannonballs it fires will
bounce off of floors, explode on walls, and can smash through multiple weaker
enemies before exploding.
DP weapon tile numbers
DB Shotgun 6324
Cruizer shotgun* 8830
MP5 SMG* 8833
*These do not
need to be placed in maps, since they will automatically replace the regular
shotgun and chaingun, if the option is selected in
the menu or by the mapper.
Duke’s Skycar
Tile #6412 is a vehicle that the player can
get in and control. It does not require
any special tags to work. Just place the
tile in the map, then Duke can fly it. Once in the Skycar,
the mouse controls steering, forward accelerates, backwards decelerates, strafe
left/right does barrel rolls, primary fire shoots explosive bullets, secondary
fire drops big bombs, and the open key ejects.
Making a Skycar
crash sequence. A crash
sequence will only work at the start of a map.
Place tile #6410 in the air,
along with the player start position.
Place a series of LOCATORS, creating a path for the crashing skycar to follow.
The final locator in the sequence should have a lotag
of 0, with previous ones counting up.
Give the skycar a lotag
equal to that of the first locator in the sequence. For example, if you have placed 16 locators,
then give the first locator and the skycar both a lotag of 15. The
next locator will have a lotag of 14, and so on until
you get down to 0. The locators can be
as far away from each other as you like.
However, keep in mind that the crashing skycar
cannot make tight turns. If you have
placed the sprites correctly, then the map will begin with Duke in the skycar as it follows the path and random explosions
surround it. When it reaches the lotag 0 locator, it will crash, Duke will get out and say
“That’s the second time those alien bastards have shot up my ride!”. Ironically,
Duke cannot be harmed while in the crashing skycar,
although he can be harmed in the controllable skycar.
Skycar Bonus
Rings
These are the
glowing rings (tile #6419) that the Skycar flies through in the demo level. Place them in the sequence you want, with
ascending lotags, starting at lotag 0 (see
Skycar1.map in dpmaps). Rings with pal 33 will act as boosters. Set YVEL on the ring to make it activate
ACTIVATOR, ACTIVATORLOCKED, MASTERSWITCH, RESPAWN, and various DP sprites when
the ring is completed in game. You can
make the level impossible to exit until a certain ring has been flown
through. To do this, choose the exit
sector, but instead of giving it a lotag of -1 (or
65535), place a SE in that sector and give the SE a lotag
of -1. Finally, set
EXTRA on the final ring (or whichever one you want to enable the exit) to 1. Completing that ring in game will cause any
sectors with lotag -1 SEs
to become exit sectors.
Saw Blades
In addition to being
normal objects that can be picked up by the player, saw blades (tile # 8006)
are especially effective when fired from the gravity gun. They do a large
amount of damage and bounce off of walls several times as they lose momentum
and eventually come to rest.
A
Warning about activation tags...
Many Duke Plus
sprites use the YVEL tag as an activation number, similar to how switches and
other standard sprites use lotag. It is
recommended that, whenever possible, the activation number on DP sprites not be
shared with the activation number on the regular hardcoded sprites. For
example, suppose you have a switch with a lotag of 53, and it opens a door. But you also want the switch
to activate a SPAWNER. You could give the switch and the SPAWNER a YVEL
of 53, and it should work. But it would be
safer to give the switch and SPAWNER a separate YVEL, such as
54 (assuming that 54 is not being used as a lotag
or YVEL somewhere else). So in this case, you would give the switch and
the door activators a lotag of 53, and you would give
the same switch and the SPAWNER a YVEL of 54.
Special
Tags
Slippery
floors
To make the
floor of a sector slippery, give the sector a lotag
of 50. Sprite surfaces can be made slippery by setting the lotag
of the sprites to 50 (sprites must be floor aligned for this to work)..
Activation by
Monsters
Set the YVEL of
a monster to make it activate all ACTIVATOR, RESPAWN,
ACTIVATORLOCKED and MASTERSWITCH that have lotag
equal to the YVEL you set (must be nonzero). The activation occurs when the
monster dies.
Sprites that
can only be seen when the nightvision goggles are
used
Give a sprite a
pal of 66, and it will be not be visible or solid unless the goggles are on.
This works on enemies, pickup items, sprite bridges – any sprite at all.
Pulsating
sprites
To make a sprite
pulsate in-game (the shade of the sprite will rise and fall), add 70 to its
pal. For example, if you want the pulsating sprite to be pal 0 in-game, give it
a pal of 70 in mapster. To make a
pal 2 pulsating sprite, give it a pal of 72. Next, to change the rate of
pulse, set the hitag of the sprite. A hitag of 0 will give a rapid pulse, while 1 is slower, 2 is
even slower, and so on. Obviously, do not use this effect on sprites that
already have a hitag set for some other purpose.
Tree Cstats
Give a tree
sprite (tile #908 or #910) a nonzero lotag,
and it will retain whatever cstat you give it in the
map (flat, nonblocking, etc.) Normally, trees
are hardcoded to become blocking and non flat in-game.
