Sectors:  circular sectors

 Convex doors:  notes

 





notes on convex doors
  • (standing in front of them in 3D mode) The left door's sprite must have a palette of 2. In the above image, this sprite is indicated by a yellow tail.

  • The sprites for the rotation effect must have the same hitags; central sprite has a lotag of 1 and the one in each door a lotag of zero.

  • The activators must have their tails point in the same direction as the central sprite.

  • Both door sectors must be given a lotag of 30.

  • If you were to add gspeed sprites, their tails would also have to point in the same direction as the central sprite. Side effects of adding gspeed sprites: the doors won't open as far as they do without gspeed sprites.

  • Want to add sound? Only one door sector needs a music sprite.

  • If you have to (or want to) shorten the door sectors... say, you want to chop the back ends shorter, just join two points away from the back of these doors and join the ends with the parent sector. NOTE: Make sure you join the parent with the end sectors. You do not want to join them the other way round. If you press j first inside the door sector and then the parent, the parent sector may end up at a different ceiling height than what you expected. Make sure you press the j key first in the parent sector then in the sector you want to get rid of.

  • Want to have these doors swing open instead of rotating open? Instead of worrying about a central sprite, just place one sprite in each of these doors where you want the door hinge and give them the same unique hitags and lotags of 11. It works and it's really cool. Remember to give the door sectors a lotag of 23. Really important: you would also have to join the house sector (the outer most circular sector) with the parent sector. Other wise, the doors will disappear when they swing open. You will also have to experiment with the direction of the hinge sprite's tails until they open the way that they should. NOTE: with sector lotag 23, you don't need activators if you don't want them.

That's it for now! These tutorials must have the creative juices flowing, now. The stuff that I have talked about in these tutorials on circular sectors is surely only the beginning of what you can think of doing with this information. I hope it helps you create some awesome Duke3D levels.     Enjoy.     JS
