copy this over to your script file. it SHOULD work now.

also, make sure you have named the door and the key correctly in the .map file.

it didn't work. and, by the way, its the same script as my.
is there any chance the game doesn't recognize the HPS file?

I know its too much to ask, but, maybe, you can build a simple room - just a door with a key on the floor, and behind it the exit. really simple, without wells and ceiling. and with that script of the key that needed to open the door. then sent it to me and i'll try to figure it out.
