Hi mercuryus, I've found a little bug. I assigned the elevator action from your script to my entity ( mdl ), everything works, I adjusted the numbers in the array, it can also travel from level to level, BUT when i stand on it and press for example, the 2, it goes up, but passes right through the player. Ive checkmarked the polygon flag in the main options, not in the script, tried with only checking Bbox, and tried adding my.polygon = on in the script, nothing happens, the same with the line my.passable = off, and I recompiled the level after each time. Please help.
