Thanks for the reply pio.
I tried that angle (pun only slightly intended) and was successful in identifying the object directly “behind” the cursor using scene.pick, even getting that object’s world position. But, if my ground plane is positioned at 0,0,0 I can only get that position directly from the object, which doesn’t do me any good. What I need to know are the coordinates of the point where the cursor bisected the object, relative to its center, from the origin of the camera view. That would tell me the direction and distance I would need to move another object within world space.
I thought I had come up with a solution but the immediate problem I ran into was the closed nature of the framework. So, after a few days of unproductive grumbling I decided that the only way I was truly going to accomplish what I wanted was to build everything from the ground-up. I still think Proscenium has great potential but I’m done waiting for a RC. For anyone who’s thought about digging into heart of stage3D and building their own framework, but thought it would be incredibly difficult, well, it is. At least it as for me but anyone who would find it easy probably isn’t in this forum. After climbing a steep learning curve (AGAL and I are back on speaking terms) I finally got going and am extremely pleased with what I’ve accomplished. Granted, I did spend a lot of time initially banging my forehead on my desk but I finally “got it”, and with only a slight concussion.
The resources are out there.
