MovieClip hitTest

Hi,

I’ve created a moving MC (responding on Up,Left,…).
But I want I to NOT move if it’s underneath something like a wall.
I’ve named the wall “muur”. Any suggestions to stop the MC moving if it’s right underneath/above/ left to/right to the wall, so you’ll have to go around the wall. I tried some hitTest stuff, but it didn’t work. Though I think it’s related with hitTest.
Anyone?

Luster,
