Bullet Cocos3D Wrapper

IMPORTANT!!

You need to edit your build settings and add a NOT recursive header search path "./Bullet\ Wrapping/src/" WITH the quotes to the "Header Search Paths" and "User Header Search Paths".

create an instance of CC3PhysicsWorld (contains a btDiscreteDynamicsWorld)

CC3PhysicsWorld *_physicsWorld = [[CC3PhysicsWorld alloc] init];

and set it's gravity

[_physicsWorld setGravity:0 y:-9.8 z:0];

create a physics object

//for a box that is 1 x 1 x 1

CC3MeshNode *boxNode;

btCollisionShape *boxCollisionShape = btBoxCollisionShape(btVector3(1,1,1));//I might provide a wrapper sometime in the future.

CC3PhysicsObject3D *boxObject = [_physicsWorld createPhysicsObject:node shape:boxCollisionShape mass:1 restitution:0.3 position:boxNode.location];

apply force/impulse

[boxObject applyForce:cc3v(0,1,0) position:boxObject.node.position];

[boxObject applyImpulse:cc3v(0,1,0) position:boxObject.node.position];

you need to call this in an update method:

[_physicsWorld synchTransformation];

to set the location of a physics object you need to delete the object then re-make it
