Alright, I’m finally trying to get my chops together with AS 3.0 and make everything its own class. I make mainly games, and I’m having a hard time figuring out how to hitTest 2 instances of separate classes.

In this case, I’ve got a Bomb class and a Dinosaur class that I instantiate using functions as follows (The user drops bombs which fall onto the Dinosaurs):

function dropBomb() {  
var bomb:Bomb = new Bomb();  
addChild(bomb);

}

function makeDinosaur(evt:TimerEvent) {  
var newDino:Dinosaur = new Dinosaur();  
addChild(newDino);

}

The classes handle their respective animations, but when I try to use HitTest on the main timeline, it doesn’t recognize “bomb” or “newDino” because they’re inside of functions. Does anyone know how to do this?

Thanks,  
Haig
