I'm sure everyone is familiar with the cartoon holes in the wall. Pick up a black circle, throw it onto a wall and now you can walk through the wall.

I'm looking for a code that'll let me do that.
I know I can just create an entity at the throw point that will just move me to the new location, but I want to smoothly walk through it. So I can be halfway through the wall as opposed to being in one spot and then just appearing in another.

I also need to make sure that the hole will show up only on parts where there is enough space on that texture surface. I.e. not on the corners where it'll overlap the edge. I would assume a c_trace would work for this, just not sure how to do it.

thanks
