You don’t need all these things. Just use hitTest with images with alpha channels. Simple like that, just ONE LINE.

This class works better than any similar class I’ve used, because it takes complex nesting into account. I did have a problem when hit testing against objects that have alpha, and the fix was to force the search color to #000000. To do that, insert this after line 50. searchColor = 0×000000;

This article helped me finding the intersection point between two lines using getCollisionPoint()

Thanks a lot!

Uses the bounding box. Not pixel perfect at all.

You shouldn’t have to import it if you have the class file in your Classes folder.

Looks like you need to put in

import flash.display.MovieClip;

in the class.
