Press any key to restart with different random starting position. Yes, that's as interactive as it gets!

A few points of note:

  • The mesh is dynamically broken into parts at runtime. Because this is a random process, it sometimes results in odd-shaped pieces which don't look very good.
  • Particle effects are created in response to collisions between objects. If a lot of collisions occur, it can get very slow. There really should be some kind of limiter to keep things under control.
  • Apparently the deferred explosion code causes the breakup time to vary quite a lot on slower computers. This might mean that the ship touches the ground before exploding. It's supposed to explode in the air!
  • The ground is made out of three pieces: a visible mesh, a solid box collider a short way below the surface, and a trigger between the two. The trigger is used to increase the drag of objects which fall into it, in an attempt to simulate the effect of a large object ploughing into the deep dust of a moon's surface.
  • There's no sound, because it's in space, right? Not that this explains the shockwave....
  • The code has an exciting mixture of good, generalised design and random hardcoded values. The latter is a consequence of making changes just before the deadline.
  • I made this specifically for this contest, using material from my game Phoenix Final (and a texture from Rescue). The plan is that this explosion effect will be rolled back into Phoenix Final to replace the pretty basic effect that's there at the moment.
