Mass Collision Detection - Page 5

Pretty easy, we're going to do the same thing for the boxesOnScreen array, but we'll also add our collision detection to this for loop.

for (j in boxesOnScreen) {				
	this[boxesOnScreen[j]]._y -= 7;
	if(this[boxesOnScreen[j]]._y < 0) {
		this[boxesOnScreen[j]].removeMovieClip();
		boxesOnScreen.splice(j, 1);
	}

	for(k in ballsOnScreen) {			
		if (this[boxesOnScreen[j]].hitTest(this[ballsOnScreen[k]])) {	
			this[boxesOnScreen[j]].removeMovieClip();
			boxesOnScreen.splice(j, 1);
			this[ballsOnScreen[k]].removeMovieClip();
			ballsOnScreen.splice(k, 1);
		}
	}
}
