Flash Week | Day #1 – Dynamic navigation menu’s with Papervison 3D

19. Interactive3DSceneEvent
The Interactive3DSceneEvent can be seen as the MouseEvent for Papervision. It is pretty simple to translate over, as the event types are similar in name to those of the MouseEvent. The only thing to remember when using the Interactive3DSceneEvent is that instead of using OBJECT_CLICK for the MouseEvent.CLICK, use OBJECT_PRESS. OBJECT_CLICK can be very unpredictable, always use OBJECT_PRESS. The scene object is the stage for Papervision and we must add the planes to the scene before we can see them. The startRendering function starts the onRenderTick function in the Base class, which handles all the native Papervision animation. It’s basically just an ENTER_FRAME event handler.

plane.addEventListener(InteractiveScene3DEvent.OBJECT_PRESS, clicked);
plane1.addEventListener(InteractiveScene3DEvent.OBJECT_PRESS, clicked);
plane2.addEventListener(InteractiveScene3DEvent.OBJECT_PRESS, clicked);
plane.addEventListener(InteractiveScene3DEvent.OBJECT_OVER, over);
plane1.addEventListener(InteractiveScene3DEvent.OBJECT_OVER, over);
plane2.addEventListener(InteractiveScene3DEvent.OBJECT_OVER, over);
plane.addEventListener(InteractiveScene3DEvent.OBJECT_OUT, out);
plane1.addEventListener(InteractiveScene3DEvent.OBJECT_OUT, out);
plane2.addEventListener(InteractiveScene3DEvent.OBJECT_OUT, out);

scene.addChild(plane);
scene.addChild(plane1);
scene.addChild(plane2);
startRendering();
TweenLite.to(plane, .5, {alpha:1});
TweenLite.to(plane1, .5, {alpha:1, delay:.5});
TweenLite.to(plane2, .5, {alpha:1, delay:1});
}
