I have a script (to be released soon) that places a model on the map (.mdl).. I need to NOT allow users to pass through it like they currently can, and I can't figure out a way to do this..
1) I was thinking that there could be flags that allow you to make it solid (which I must be stupid because I can't seem to find them)
2) Collision detection -- Just detect if the user is walking into the wall, and if they are, then move them or disallow the move..
