checking for...

I was wondering how you would check during a hittest to see if what your hitting has a certain variable atatched to it.

Say, occasionally when I hit the mc "bob" he's happy, so bob.happy = true. but some time he's not, so bob.happy = false

How would I check for this during a hittest?

Am I being clear enough?

for example
if(_root.bob.hitTest(_root.square)){
if(_root.bob.happy){
//if true do this
}else{
// if not do this
}
}
