This causes a ceiling to fall when an explosion is detected within the sector. This effect was not used in the game. It was probably made for testing reasons only, but it's still pretty cool.
Create the sector with the ceiling which will fall. Place an S[Channel,19]
(Speed[0,Speed]) within the sector. The Channel can be used to activate other S[Channel,19]
sprites at the same time. It is also logical to place an explosive of some sort in your level.
Notes:
- The message "unlocked" will be displayed when the ceiling begins to drop.
- The game does not check if a shot or object passes through the sector.
- The ceiling will only begin to drop when an explosion occurs somewhere within the sector.
