Collapsable Sprites can be destroyed by explosives. The collapsable bridges which appear to be "truly 3D" are actually made up of sprites.
To make a sprite collapsable, give it a unique Hi-Tag. Any sprites sharing the same unique Hi-Tag will fall at the same time.
A Collapsable Bridge is constructed with floor-aligned sprites,
resized to cover a gap. Make it blocked, and make sure it is two-sided
(use the 1
key if it isn't). Give the
bridge sprite a unique Hi-Tag to make it collapsable. To make the
bridge seem truly 3D, add blocked sprites to the bottom and sides of
it. To make the entire 3D bridge collapsable, give all of the bridge
sprites the same unique Hi-Tag (effectively a Channel
).
Note: Ugly graphic glitches can occur with 3D bridges. Sprites
will often show through each other when they shouldn't be visible. To
fix this, make all of the bridge sprites one-sided with the 1
key. This way, all of the hidden sides (which caused the graphic
glitches), will be completely invisible and will cause no more
problems.
