Okay, Now I'm making my next map. I have first chamber nearly ready, but I have to ask one little question, so here it is.
How can I make platform that move up and down like there is in chamber 15 in front of elevator? I have platform model (prefab), but I need to know how can I make it work like this: First platform is up. When the box is placed on the button, platform will move down, when the box is removed from the button, platform will move back to up. I have only model, so what entity and I/O works I have to do? please answer, if you want next map released soon.

I'd guess: parent the elevator to an invisible func_door brush, then set up the IO just like you set it for ordinary door. Set the func_door movement speed to something low. It should work with this setup...

Edit: Nevermind... Yes a door should work, or a path_track and func_tracktrain.

thank you

GASP!!! I know prefabs are tempting, but unless you've made them, you don't learn a god damned thing from them! Yes, I use prefabs. HOWEVER, I make them from scratch by observing objects in-game and through trial and error. Panapappa, not to be mean, but you wont learn shit from using prefabs, other than how to drag and drop. Go to some A.A. meetings, get a prefab-patch and a sticker that says 'I've quit and so can you!' and STOP USING PREFABS!!
Please.
