메소드 설명
ApplyAngularImpulse ( float impulse ) : void

Apply an angular impulse.
ApplyForce ( Vec2 force, Vec2 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.
ApplyForceToCenter ( Vec2 force ) : void

Apply a force to the center of mass. This wakes up the body.
ApplyLinearImpulse ( Vec2 impulse, Vec2 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 ( BodyDef bd, World world ) : System
CreateFixture ( FixtureDef def ) : Fixture

Creates a fixture and attach it to this body. Use this function if you need to set some fixture parameters, like friction. Otherwise you can create the fixture directly from a shape. If the density is non-zero, this function automatically updates the mass of the body. Contacts are not created until the next time step.
CreateFixture ( Shape shape, float density ) : Fixture

Creates a fixture from a shape and attach it to this body. This is a convenience function. Use FixtureDef if you need to set parameters like friction, restitution, user data, or filtering. If the density is non-zero, this function automatically updates the mass of the body.
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.
GetLinearVelocityFromLocalPoint ( Vec2 localPoint ) : Vec2

Get the world velocity of a local point.
GetLinearVelocityFromLocalPointToOut ( Vec2 localPoint, Vec2 result ) : void
GetLinearVelocityFromWorldPoint ( Vec2 worldPoint ) : Vec2

Get the world linear velocity of a world point attached to this body.
GetLinearVelocityFromWorldPointToOut ( Vec2 worldPoint, Vec2 result ) : void
GetLocalPoint ( Vec2 worldPoint ) : Vec2

Gets a local point relative to the body's origin given a world point.
GetLocalPointToOut ( Vec2 worldPoint, Vec2 result ) : void
GetLocalVector ( Vec2 worldVector ) : Vec2

Gets a local vector given a world vector.
GetLocalVectorToOut ( Vec2 worldVector, Vec2 result ) : void
GetLocalVectorToOutUnsafe ( Vec2 worldVector, Vec2 result ) : void
GetMassData ( MassData data ) : void

Get the mass data of the body. The rotational inertia is relative to the center of mass.
GetTransform ( ) : Transform

Get the body transform for the body's origin.
GetWorldPoint ( Vec2 localPoint ) : Vec2

Get the world coordinates of a point given the local coordinates.
GetWorldPointToOut ( Vec2 localPoint, Vec2 result ) : void
GetWorldVector ( Vec2 localVector ) : Vec2

Get the world coordinates of a vector given the local coordinates.
GetWorldVectorToOut ( Vec2 localVector, Vec2 result ) : void
GetWorldVectorToOutUnsafe ( Vec2 localVector, Vec2 result ) : void
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.
SetMassData ( MassData massData ) : void

Set the mass properties to override the mass properties of the fixtures. Note that this changes the center of mass position. Note that creating or destroying fixtures can also alter the mass. This function has no effect if the body isn't dynamic.
SetTransform ( Vec2 position, float angle ) : 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.
ShouldCollide ( Body other ) : bool

This is used to prevent connected bodies from colliding. It may lie, depending on the collideConnected flag.
SynchronizeTransform ( ) : void
