I'm playing around with jbox2d and can't really make a body "fly away" as if from an explosion.
From what I have found on the net, making the body fly away from the world center (0,0), should have been something like that:
b.applyLinearImpulse( new Vec2(0,0) , b.getPosition() );
But really it just doesn't do anything, any idea why? Also how do I change the strength of the impulse, like if it want to make it fly skyhigh or just move a bit?
