Yep, it's the Y being wrong, not the X
(as said by bwy in comment #2)

This is the same bug as http://www.juegosfan.com/commando-2, when the aircraft gone, the soldier fall from the house...

Tests welcome.

This has to do with MovieClip.hitTest. pointInBounds() returns false when it should be true. The problem may be to do with the 'camera' effect, which changes root's _x translation. Anyway, assuming getBounds() is correct, the only possible error is in getWorldMatrix(), as the x and y arguments are passed.

In any case, the hit is registered at the correct height (always the same, I think), but at the wrong x position.

bowman.swf (lots of versions on the internet) works pretty well. However, in all games the point where a hit is registered is miles away from where it should be. This version:

has a 'bird hunting' game, where a hit is registered some distance under the birds.

When playing against a computer opponent, you are hit if the arrow lands a short distance behind you, your opponent usually much closer to you than he's drawn.

The opponent's bow also looks strange, but I haven't seen what it looks like on the pp
