I you already know that steam let's you create your own cs(counter strike) map. All you do is go into play games and all the way at the bottom is a button that says source sdk. that is the program to make a map. I am just wondering, i have done most of the map and it is a mansion and it is really cool. i have just created it and have a side a roof and a floor and others. if anyone has used this program can you tell me how to make the doors push open. I have a door with a door frame a such and it kills me that i can't open it while i play. if any information for this problem that i am having please reply back.

Thx whitesox088
