Body
copied!<p><code>MOUSE_OUT</code> events are, evidently, handled differently for X and Y mouse moves when leaving a Sprite. </p> <p><em>How do I fix this or work around it? Where is this documented?</em></p> <p><code>MOUSE_OUT</code> occurs when <code>x==0</code>, but not <code>y==0</code> (you need to go to <code>y==-1</code>):</p> <pre><code>private var _sp:Sprite; public function test( ):void { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; _sp = new Sprite( ); _sp.graphics.beginFill( 0xFF0000, 1 ); _sp.graphics.drawRect( 0, 0, 15, 15 ); _sp.graphics.endFill( ); _sp.x = 10; _sp.y = 10; _sp.alpha = 1; addChild( _sp ); _sp.addEventListener( MouseEvent.MOUSE_MOVE, msMvCb, false, 0, true ); _sp.addEventListener( MouseEvent.MOUSE_OUT, msOutCb, false, 0, true ); } private function msMvCb( evt:MouseEvent ):void { traceMousePos( "mv", evt ); _sp.alpha = 1; } private function msOutCb( evt:MouseEvent ):void { traceMousePos( "out", evt ); _sp.alpha = .5; } private function traceMousePos( note:String, evt:MouseEvent ):void { trace( note + " -- " + evt.localX + ", " + evt.localY + ", " + evt.stageX + ", " + evt.stageY ); } </code></pre> <p>Here is a trace from moving straight up, with <code>MOUSE_OUT</code> on -1 ...</p> <pre><code>mv -- 7, 3, 17, 13 mv -- 7, 2, 17, 12 mv -- 7, 1, 17, 11 mv -- 7, 0, 17, 10 out -- 7, -1, 17, 9 </code></pre> <p>And here is a trace from moving straight to the left, with <code>MOUSE_OUT</code> on 0 ...</p> <pre><code>mv -- 3, 7, 13, 17 mv -- 2, 7, 12, 17 mv -- 1, 7, 11, 17 out -- 0, 7, 10, 17 </code></pre> <p><em>edit</em></p> <p>The same errant behavior occurs with MOUSE_ENTER.</p>
