Dynamically access a face of a cube Software: Away3D 3.x

lostirc, Newbie Posted: 01 August 2011 07:40 PM Total Posts: 5 I’m trying to change the material on the face of a cube on mouse over. Right now I’m creating my cube primitive and adding a mouse over listener `var cube:Cube = new Cube({material:cubeMat, width:200, height:50, depth:100}); cube.addOnMouseOver(handleOver);` Inside my handleOver method I have this `private function handleOver(e:MouseEvent3D):void{ var newColor:uint = 0x00B2EE; e.currentTarget.material = new PhongColorMaterial( newColor,{specular:0.2,shininess:5}); }` This however changes the entire cube’s material. Is there any way to access the individual face dynamically so I can change it’s material?
Stephen Hopkins, Sr. Member Posted: 02 August 2011 12:18 AM Total Posts: 110 [ # 1 ] I think Away3D 3.6 or 3.5 has a Cube6 class, that lets you specify the material of each face. Signature http://www-scf.usc.edu/~shopkins
lostirc, Newbie Posted: 02 August 2011 12:28 AM Total Posts: 5 [ # 2 ] I just took a look at Cube6, it looks like that’s in away3dlite. You can access each edge of the cube using this: `e.currentTarget.cubeMaterials.back` I just can’t seem to figure out how to access that property dynamically using the event.
Stephen Hopkins, Sr. Member Posted: 02 August 2011 12:39 AM Total Posts: 110 [ # 3 ] Hmm, Away3D Cube has the property, cubeMaterials, http://away3d.com/livedocs/3.6.0_lib/away3d/primitives/Cube.html#cubeMaterials Not sure of the order you add them, though. Can probably figure that out by looking at the source. This might be a ghetto way to do it, but you can look at the material of the mouseEvent3D, and see which one it matches in the cubeMaterials property, then change that one.

lostirc, Newbie Posted: 02 August 2011 12:43 PM Total Posts: 5 [ # 4 ] A trace of `trace(e.currentTarget.cubeMaterials); //returns [object CubeMaterialsData]` not sure if that’s useful or not. Is it possible to assign a name to each face that I can somehow access through the MouseEvent3D?
lostirc, Newbie Posted: 02 August 2011 12:47 PM Total Posts: 5 [ # 5 ] I just took a look, it looks like that object is specific to the entire cube. Is there a way to attach listeners to each face individually? It’s not ideal but it could be a workaround
Somokon, Member Posted: 02 August 2011 03:40 PM Total Posts: 75 [ # 6 ] Inside the handler function, you could take a look at the event.localX, event.localY, and event.localZ coordinates, and use those to determine which face of the cube has been clicked. It’s not perfectly precise, but it works well for me.
