Cannoneer turn controller

Shown above is the turn controller for Cannoneers. Players can click on it to register; the owner of the device can use a dialog menu to join/start/reset the game; and player order is randomised.

It was fairly easy to lock player controls so that only one person can move at a time; and that turns ends either after 10 seconds have passed, after they have moved 5 metres, or (soon) after they have fired (I still have it allowing multiple shots for final testing).

Also shown in the image is the HUD for switching between the two ammo types: shells that explode on impact (small area, large damage), and grenades that explode after 5 seconds (wider area, low damage).
