ok... I need a few...
1. I need a modification to the ambiant cog at massassi "scream" cog. it plays the wav repeatedly, but I needed it random. The random ambiant cog that comes with JK plays it through out the level, and I need it only in certain areas.

2. I have an elevator in my level, and I wanted when the elevator is at the bottom, a light comes on outside (texture 00tup.mat), and when it is at the top, the light comes on up there... maybe it could be made to where the surface changes to a second cell when the elevator enters a certain sector
there is also a sector between the two sectors where the elevator stops.

I have this cog to take care of it, but it don't work...

# Jedi Knight Cog Script

# 00_elev_switch4.cog
#
# This elevator will go up to frame one, sleep, then come back down to frame 0 when
# entered from the bottom. When entered from the top, it should stay at the bottom.
# The button surface is a call switch you can put at the top to call the thing up there.
# Elevator will react to "blocked" message.
