Adding MOUSE_OVER event to ObjectContainer3D? Software: Away3D 4.x

owntheweb, Jr. Member Posted: 15 February 2013 08:02 PM Total Posts: 32 Hey, I created a “Tile()” containing multiple messes in Prefab3D, exported for Away3D. It extends ASBase() which extends ObjectContainer3D() in a predictable Prefab3D manner. I also exported a “PrefabProject.as” from which I’m expanding upon below. How do I trigger a mouse over event for my new Tile() object? I’ve tried the following based on this tutorial for meshes (no errors but no results either, perhaps because it’s not a mesh!): http://away3d.com/tutorials/Introduction_to_Mouse_Picking ... private function initContent():void { _prefabOutput = new Tile(); _view.scene.addChild(_prefabOutput); //!!!new!!! _prefabOutput.mouseEnabled = true; _prefabOutput.addEventListener( MouseEvent3D.MOUSE_OVER, onTileMouseOver ); _camera.lookAt(_prefabOutput.position); } //new function private function onTileMouseOver( event:MouseEvent3D ):void { trace('hi'); //sadly, no trace "hi" event.target.onMouseOver(); //no trace "hi", so no do cool new things here } ... Looking at the documentation, I see that an ObjectContainer3D() does have a “mouseOver3d” event, but getting it to click in my brain isn’t happening at the moment. http://away3d.com/livedocs/away3d/4.0/away3d/containers/ObjectContainer3D.html#event:mouseOver3d Any thoughts on how to proceed? I truly appreciate the assistance in advance! Best regards, Chris

I can target all of the child meshes of the Tile() object and get the mouse over method called (YAY!). private function initContent():void { _prefabOutput = new Tile(); _view.scene.addChild(_prefabOutput); //new for(var i:Number=0;i<_prefabOutput.meshes.length;++i){ _prefabOutput.meshes[i].mouseEnabled = true; _prefabOutput.meshes[i].addEventListener( MouseEvent3D.MOUSE_OVER, onTileMouseOver ); } _camera.lookAt(_prefabOutput.position); } private function onTileMouseOver( event:MouseEvent3D ):void { trace('hi'); //YAY IT WORKS! //uh oh, need to get Tile()'s methods, not child mesh's non-existing method event.target.onMouseOver(); } But now I’m having scope issues, needing to call the parent Tile() method onMouseOver, not the event.target non-existing onMouseOver event. I’ll keep digging. Let me know if I should skip all this and do something simpler. Thanks…
owntheweb, Jr. Member Posted: 15 February 2013 09:18 PM Total Posts: 32 [ # 2 ] Alright this works fully: private function initContent():void { _prefabOutput = new Tile(); _view.scene.addChild(_prefabOutput); for(var i:Number=0;i<_prefabOutput.meshes.length;++i){ _prefabOutput.meshes[i].mouseEnabled = true; _prefabOutput.meshes[i].addEventListener( MouseEvent3D.MOUSE_OVER, onTileMouseOver ); } _camera.lookAt(_prefabOutput.position); } private function onTileMouseOver( event:MouseEvent3D ):void { //ok this works... event.target.parent.parent.parent.parent.onMouseOver(); } BUT: is there a way to add mouse over events only to the parent Tile() object and not its child meshes? “event.target.parent.parent.parent.parent.onMouseOver();” looks a bit messy to me, and one event listener seems better than the 4 I’m currently using. Thanks again, EDIT: I had a misunderstanding of what “submeshes” were. I reconstructed, imported and am now reconfiguring a game piece so it now is ONE mesh with 4 submeshes. That makes my mouse interaction easier with less mouse event tracking. I’m still curious about ObjectContainer3D() mouse interaction, but am doing well enough to proceed now. Thanks for taking a look. :D
