hi, guys

i'm just trying to build a map, and i got an idea. i remember the rats map from cod2, where you press a button, when standing in front of a button and the elevator moves down and up. i would like to do something like that for my map. i wanted to put a button into the one room, and when you press use in front of it the entrance door of the house opens. is that possible, and when yes, how?

I can't see why not. There's a COD tutorial here: http://www.modsonline.com/Tutorials-read-169.html

The principles should work in COD4, as I used this tutorial to create an elevator in COD2.
