Variables

a cpFloat a;: Rotation of the body_ around it's center of gravity in radians. Must agree with cpBody.rot! Use cpBodySetAngle() when changing the angle for this reason.
data cpDataPointer data;: User definable data pointer. Generally this points to your the game object class so you can access it when given a cpBody reference in a callback.
f cpVect f;: Force acting on the rigid body_'s center of gravity.
i cpFloat i;: Moment of inertia of the body_. Must agree with cpBody.i_inv! Use cpBodySetMoment() when changing the moment for this reason.
i_inv cpFloat i_inv;: Moment of inertia inverse.
m cpFloat m;: Mass of the body_. Must agree with cpBody.m_inv! Use cpBodySetMass() when changing the mass for this reason.
m_inv cpFloat m_inv;: Mass inverse.
p cpVect p;: Position of the rigid body_'s center of gravity.
position_func cpBodyPositionFunc position_func;: Function that is called to integrate the body_'s position. (Defaults to cpBodyUpdatePosition)
rot cpVect rot;: Cached unit length vector representing the angle of the body_. Used for fast rotations using cpvrotate().
t cpFloat t;: Torque applied to the body_ around it's center of gravity.
v cpVect v;: Velocity of the rigid body_'s center of gravity.
v_limit cpFloat v_limit;: Maximum velocity allowed when updating the velocity.
velocity_func cpBodyVelocityFunc velocity_func;: Function that is called to integrate the body_'s velocity. (Defaults to cpBodyUpdateVelocity)
w cpFloat w;: Angular velocity of the body_ around it's center of gravity in radians/second.
w_limit cpFloat w_limit;: Maximum rotational rate (in radians/second) allowed when updating the angular velocity.
