透明区域中的MouseEvent.CLICK

Question

I have a movieClip that i want to get mouse click event on it, it works fine but it doesn't fire this event when i click on transparent area. is there any solution except to define a rectangle as hitArea?

mc.addEventListener(MouseEvent.CLICK, onMouseClickEvent);

function onMouseClickEvent(event:Event) {

    trace("on clicked");
}

Answer 1

It's true that you won't be able to click the transparent area, however, here is an alternate solution.

If you can monitor your mouse state with a global listener like:

stage.addEventListener( MouseEvent.CLICK, onStageClicked );

Then you can write another function that does a hit test against your display object:

public function mouseTest( someAsset:DisplayObject ):Boolean
{
    return someAsset.hitTestPoint( stage.mouseX, stage.mouseY );
}

Last from your onStageClicked() handler:

private function onStageClicked( e:Event ):void
{
    if ( mouseTest( mc ) )
    {
        //do something
    }
}

That should suffice for the transparent area.
