while you are at flash, why not copy that "bitmapdata.hittest", paste it in the help files and see what happens?

bur it is the last 11 lines.
thank you for the help

Just pasting the relevant function would have been enough, also wrap your code in [ as ][ /as ] tags.


i can't find out how to use bitmapdata.hittest, is there someone that can explain me how to use it.
Do as pantas said, and look it up on livedocs.

if you have trouble understanding something in particular, then we can help you.

okey here is an example, of what i wan't to do, i need ball to detect when it hit ball2, i have read that when you use bitmapdata, it will detect when hit, so you don't need to, create multiple points, but just one.
the problem is that i don't now how it works, i have read, a lot, but i just can't get it to work, will you still help me thank you



stage.addEventListener(MouseEvent.MOUSE_DOWN, drag);
stage.addEventListener(MouseEvent.MOUSE_UP, up);

function drag(e:MouseEvent)
{
ball2.startDrag();
ball2.bitmapData.hitTest(ball,0,ball,ball2,0);
}

function up(e:MouseEvent)
{
ball2.stopDrag();
}
