Field Documentation

cpFloat cpBody::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.

cpDataPointer cpBody::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.

cpVect cpBody::f

Force acting on the rigid body's center of gravity.

cpFloat cpBody::i

Moment of inertia of the body. Must agree with cpBody.i_inv! Use cpBodySetMoment() when changing the moment for this reason.

cpFloat cpBody::i_inv

Moment of inertia inverse.

cpFloat cpBody::m

Mass of the body. Must agree with cpBody.m_inv! Use cpBodySetMass() when changing the mass for this reason.

cpFloat cpBody::m_inv

Mass inverse.

cpVect cpBody::p

Position of the rigid body's center of gravity.

cpBodyPositionFunc cpBody::position_func

Function that is called to integrate the body's position. (Defaults to cpBodyUpdatePosition)

cpVect cpBody::rot

Cached unit length vector representing the angle of the body. Used for fast rotations using cpvrotate().

cpFloat cpBody::t

Torque applied to the body around it's center of gravity.

cpVect cpBody::v

Velocity of the rigid body's center of gravity.

cpFloat cpBody::v_limit

Maximum velocity allowed when updating the velocity.

cpBodyVelocityFunc cpBody::velocity_func

Function that is called to integrate the body's velocity. (Defaults to cpBodyUpdateVelocity)

cpFloat cpBody::w

Angular velocity of the body around it's center of gravity in radians/second.

cpFloat cpBody::w_limit

Maximum rotational rate (in radians/second) allowed when updating the angular velocity.
