Public Methods

Method Description
ApplyAngularImpulse ( float impulse ) : void

Apply an angular impulse.
ApplyForce ( Vector2 &force ) : void

Applies a force at the center of mass.
ApplyForce ( Vector2 force, Vector2 point ) : void

Apply a force at a world point. If the force is not applied at the center of mass, it will generate a torque and affect the angular velocity. This wakes up the body.
ApplyLinearImpulse ( Vector2 impulse ) : void

Apply an impulse at a point. This immediately modifies the velocity. This wakes up the body.
ApplyLinearImpulse ( Vector2 impulse, Vector2 point ) : void

Apply an impulse at a point. This immediately modifies the velocity. It also modifies the angular velocity if the point of application is not at the center of mass. This wakes up the body.
ApplyTorque ( float torque ) : void

Apply a torque. This affects the angular velocity without affecting the linear velocity of the center of mass. This wakes up the body.
Body ( World world ) : System
Body ( World world, Object userData ) : System
CreateFixture ( Shape shape ) : Fixture

Creates a fixture and attach it to this body. If the density is non-zero, this function automatically updates the mass of the body. Contacts are not created until the next time step. Warning: This function is locked during callbacks.
CreateFixture ( Shape shape, Object userData ) : Fixture

Creates a fixture and attach it to this body. If the density is non-zero, this function automatically updates the mass of the body. Contacts are not created until the next time step. Warning: This function is locked during callbacks.
DestroyFixture ( Fixture fixture ) : void

Destroy a fixture. This removes the fixture from the broad-phase and destroys all contacts associated with this fixture. This will automatically adjust the mass of the body if the body is dynamic and the fixture has positive density. All fixtures attached to a body are implicitly destroyed when the body is destroyed. Warning: This function is locked during callbacks.
Dispose ( ) : void
GetLinearVelocityFromLocalPoint ( Vector2 localPoint ) : Vector2

Get the world velocity of a local point.
GetLinearVelocityFromWorldPoint ( Vector2 worldPoint ) : Vector2

Get the world linear velocity of a world point attached to this body.
GetLocalPoint ( Vector2 &worldPoint ) : Vector2

Gets a local point relative to the body's origin given a world point. Note that the vector only takes the rotation into account, not the position.
GetLocalVector ( Vector2 &worldVector ) : Vector2

Gets a local vector given a world vector. Note that the vector only takes the rotation into account, not the position.
GetTransform ( Transform &transform ) : void

Get the body transform for the body's origin.
GetWorldPoint ( Vector2 &localPoint ) : Vector2

Get the world coordinates of a point given the local coordinates.
GetWorldVector ( Vector2 &localVector ) : Vector2

Get the world coordinates of a vector given the local coordinates. Note that the vector only takes the rotation into account, not the position.
ResetDynamics ( ) : void

Resets the dynamics of this body. Sets torque, force and linear/angular velocity to 0
ResetMassData ( ) : void

This resets the mass properties to the sum of the mass properties of the fixtures. This normally does not need to be called unless you called SetMassData to override the mass and you later want to reset the mass.
SetTransform ( Vector2 &position, float rotation ) : void

Set the position of the body's origin and rotation. This breaks any contacts and wakes the other bodies. Manipulating a body's transform may cause non-physical behavior.
SetTransformIgnoreContacts ( Vector2 &position, float angle ) : void

For teleporting a body without considering new contacts immediately.
