Re: FLASH: Collision Detection

The new hitTest method makes this way easier than it was in Flash 4. You can

either a) detect when two clips' rectangular bounding boxes intersect, or b)

determine when one clip's center point intersects another clip's *shape*

bounds.


This works great, but keep in mind it doesn't do the shape collision with

two objects' shapes - just one. Hope this isn't too confusing??!


I made a sample ActionScript that uses this on the Flash Exchange, called

Bounce. If you haven't already seen it, it may be a good starting point.

It's easier just to view this than to try to explain it further. :>)
