Box2d strange loop (objective-c, cocos2d, box2d)?

Yes, be is overwritten. But be is just a pointer into a linked list of b2Body objects. The whole purpose of be is to point to each b2Body in the list, one at a time.

I find this a bit strange and here's the code : for(b2Body *b = _world->GetBodyList(); b; b=b->GetNext()) { if (b->GetUserData()! = NULL) { CCSprite *ballData = (CCSprite *)b->GetUserData(); ballData. Position = ccp(b->GetPosition().

X * PTM_RATIO, b->GetPosition(). Y * PTM_RATIO); ballData. Rotation = -1 * CC_RADIANS_TO_DEGREES(b->GetAngle()); } } thanks objective-c for-loop cocos2d box2d link|improve this question asked Nov 4 '11 at 0:59Paul76617 96% accept rate.

Thanks rob, okay, if we compare this to for (var i=0; I – Paul Nov 5 '11 at 13:58.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
