[help] Looking for a hitTest tut

Does any body no were there is a simple tutorial on hit test?

I just need a simple one, just to stop an MC going through another one. I would prefer if it show how to use it on all four sides. I'd prefer a tutorial than a thread as not all threads are helpfull in explain how things work.I have no reason to use something i dont understand.

Im sory i didnt have time to google or search for it, i have an asignment due tomorrow and need to get on with it. And just in case some one was going to tell me, i know im stupid for learning some flash when i should be doing home work.
