They aren't moving. I'm using a flat plate created in WED and compiled so that actions can be attached to it. When I intentionally fall off the edge, my character reaches the invisible floor and then appears to be standing on thin air, and is able to run around on the invisible floor, but the code
Code:
if(event_type == EVENT_ENTITY)
	{
		beep();
	    printf("Touchdown!");
	}
doesn't seem to be running at all. I've set the polygon flag in WED now but I don't see any "not shaded" flag. I saw a "nofilter" flag so I checked that and unchecked the invisible flag. I've recompiled the level but the plate is still invisible! frown
