Tripbombs can be placed on a flat vertical surface. Once placed, they emit a red laser beam. If any players or enemies are dumb enough to walk into this beam, the tripbomb will explode.
Place a TRIPBOMB
(#2566) on a flat vertical surface, and resize it
realistically. Approximately two seconds after a tripbomb "sees" the
player, a red beam will shoot out and the tripbomb will be active. The
tripbomb itself is the source of the explosion, thus it is possible to
avoid the explosion's range simply by tripping the beam from a
distance. Also, the laser beam itself is actually a collection of
sprites, and these sprites are limited to a certain distance before
being cut short. For these reasons, you should limit the distance that the beam has to travel to reach another wall.
Notes:
- The beam will be triggered if a moving sector disturbs it.
- The beam is also triggered by clipping abnormalities, which can occur in very large sectors with long walls.
- The beam will be reflected in mirrors, and tripbombs can even be placed on a mirror, but the explosion will not damage the mirror.
I've never seen this done before, but the MORTER
(#1650) is absolutely perfect for a proximity mine. Mortar shells are
affected by transparency, palettes, and can even be manually resized.
