This is what I need help with:
<img src="http://i43.tinypic.com/2v9sls4.png" border="0" />
I want it so that if the camera Line of Sight hits the wall, it won't be seen. So if you are behind the corner (as in the picture) you won't be seen unless you step in the pink part.
My question is:
Are there any tutorials for this?
Sorry for some weird english.
