as3 MouseEvent localX acting weird

Question

Hi,

I encountered this really weird situation, I have this bar and I addEventListener to it, so when the bar's clicked, trace localX

private function _barClicked($e:MouseEvent):void {
      trace($e.localX)
}

The weird thing is that, when clicking at the same spot, sometimes it jump to a wrong number which I can't figure out why, I traced the width of the bar, and it's the right value, the localX is just giving me random numbers. Has anyone ever ran into this problem? Thanks!

Answer 1

Hmmm, strange

I've tried a simple scenario where I have a rectangle named 'bar' and pasted your listener for the CLICK event, then tried the MOUSE_DOWN event. Both worked fine. I didn't get random values.

My guess is your bar clip contains other objects inside and you might get values from children of bar, not bar itself. Not sure though, it's just a guess.

You could try to make sure that your values come from $e.currentTarget as $e.target might change depending on: your clip and how many children it holds, position of the click and event phase.

Try

private function _barClicked($e:MouseEvent):void {
      trace($e.currentTarget.mouseX);
}

Hope it helps!

I was having the same problem, and Kevin Condon solution from the comment above helped my problem. I am just posting it here, because I almost missed it in the comment.

private function _barClicked($e:MouseEvent):void {
     var coord:Point = $e.currentTarget.globalToLocal(new Point($e.stageX, $e.stageY));
     trace(coord.x);
}

Thanks Kevin.

Answer 3

Just wanted to note a variation on this problem for those for whom the above is not working.

I was having the same issue - localX showing odd values. Mine weren't random, just far lower than what I expected. I.e., click on the far right of the sprite and get only 17.2, event though the width was reporting as 160.

What I found was that my instance was a scaled version of a symbol who's native width was much less.

Once I set it up so that the symbol and the instance had the same width, I started getting the right values.

Hope this helps someone.
