This is work in progress, showing computer (AI) controlled gliders in PicaSim. All the planes except the Phase 6 at the end (when you start seeing the on-screen sticks moving) are under the control of the computer. There's no difference in the simulation between these planes and the player-controlled plane.
During the video I cycle through the camera views showing many of the planes, ending with me controlling the Phase 6, and showing that collision works between the gliders (an intentional mid-air collision!).
There's a little more to do before this is ready - mainly in terms of the user-interface for setting this up, and also adding AI to control powered planes.
The number of planes you'll be able to fly with will depend on the power of the device, but I imagine most mid-range phones will be able to simulate at least a few quite easily (perhaps many more!).
