[ODE] Shockwave of an explosion

[Nicholas Francis]

I don't know about the 'shock wave', but FWIW, here's what we did:

When we have an 'exploding' object, we found all nearby objects under  
physics control, and then applied a force away from the explosion on  
all nearby objects. In order to keep the system stable, we didn't apply  
the force all at once, but spread it out over 1 second (this actually  
looked cooler as well, as it made it look more like an air wave and  
less like somebody pushing it). We also experimented with  
applyForceAtPosition, where we set the position as the centre of  
explosion. Sometimes it looks better, sometimes not.

IIRC, the force diminished with the squared distance from explosion

If you're making game-like stuff, I advice you to just play around - it  
feels REALLY cool, is fun to make and easy to get right ;-)
