class: Body

[23:7] extends: FxObj

Wraps jbox2d's Body (com.almasb.fxgl.physics.box2d.dynamics.Body), the runtime physics body created by World.createBody. Carries the type, position, angle, linear / angular velocity, damping flags, mass data, and the attached fixtures. The Aussom wrapper exposes the read-write surface most users need. Lower-level API (transform, world-vector helpers, mass data, etc.) is reachable directly on this.obj.

Methods

Body ()

Empty default constructor; populated by adopt.
adopt (object Ajo)

Wraps an existing Body AussomJavaObject.
getType ()

Returns the body type enum AJO (STATIC / KINEMATIC / DYNAMIC).
setType (object TypeAjo)

Sets the body type from a BodyType enum AJO.
getPosition ()

Returns the world-coordinate position as a Vec2 wrapper.
getAngle ()
setTransform (object PositionVec, double Angle)

Snaps the body to (position, angle).
- @p PositionVec is a Vec2 wrapper.
- @p Angle is the angle in radians.
getWorldCenter ()

Returns the world center of mass as a Vec2 wrapper.
getLocalCenter ()

Returns the local center of mass as a Vec2 wrapper.
getLinearVelocity ()

Returns the linear velocity as a Vec2 wrapper.
setLinearVelocity (object VelocityVec)
getAngularVelocity ()
setAngularVelocity (double V)
getLinearDamping ()
setLinearDamping (double V)
getAngularDamping ()
setAngularDamping (double V)
getMass ()
getInertia ()
getGravityScale ()
setGravityScale (double V)
getTorque ()
setTorque (double V)
applyForce (object ForceVec, object PointVec)

Applies a force at a world point.
applyForceToCenter (object ForceVec)
applyTorque (double V)
applyLinearImpulse (object ImpulseVec, object PointVec, bool Wake)
applyAngularImpulse (double V)
isBullet ()
setBullet (bool V)
isAwake ()
setAwake (bool V)
isActive ()
setActive (bool V)
isSleepingAllowed ()
setSleepingAllowed (bool V)
isFixedRotation ()
setFixedRotation (bool V)
getEntity ()

Returns the attached Entity wrapper (or null).
setEntity (object EntityObj)
getUserData ()
setUserData (Data)
getWorld ()

Returns the owning World AJO.
createFixture (object FixtureDefObj)

Creates a fixture from a FixtureDef wrapper.
createFixtureShape (object ShapeAjo, double Density)

Creates a fixture from a Shape + density.
destroyFixture (object FixtureAjo)

Destroys a fixture from this body. The Fixture argument is the raw AJO returned by createFixture / createFixtureShape -- no Aussom wrapper type for Fixture exists in this layer.
getFixtures ()

Returns the list of attached fixtures as a Java List AJO.
getTransform ()

Returns the body's Transform (position + rotation) as a raw AJO. The Transform class is not wrapped — call .invokeRaw on the returned AJO for direct access.
getMassData (object MassDataAjo)

Fills a MassData AJO with the body's mass / center / inertia. Pass a Java-allocated MassData AJO; the method writes into it.
- @p MassDataAjo is the AJO to populate.
setMassData (object MassDataAjo)

Replaces the body's mass data with the supplied MassData AJO. Used to override the mass / center / inertia computed from attached fixtures.
resetMassData ()

Recomputes the body's mass data from its attached fixtures. Call after adding, removing, or changing fixtures.
getWorldPoint (object LocalVec)

Converts a body-local point to world coordinates.
- @p LocalVec is a Vec2 wrapper in body coordinates.
- @r A new Vec2 wrapper in world coordinates.
getWorldVector (object LocalVec)

Converts a body-local direction vector to world coordinates.
- @p LocalVec is a Vec2 wrapper in body coordinates.
- @r A new Vec2 wrapper in world coordinates.
getLocalPoint (object WorldVec)

Converts a world-coordinate point to body-local coordinates.
- @p WorldVec is a Vec2 wrapper in world coordinates.
- @r A new Vec2 wrapper in body-local coordinates.
getLocalVector (object WorldVec)

Converts a world-coordinate direction vector to body-local.
- @p WorldVec is a Vec2 wrapper in world coordinates.
- @r A new Vec2 wrapper in body-local coordinates.
getLinearVelocityFromWorldPoint (object WorldVec)

Returns the velocity at a world-coordinate point as a Vec2. Useful when the body has angular velocity.
getLinearVelocityFromLocalPoint (object LocalVec)

Returns the velocity at a body-local point as a Vec2.
getSleepTime ()

Returns the float-second time this body has been asleep.
shouldCollide (object OtherBody)

Returns true if the supplied Body would collide with this one under the current category / mask / group settings.
getJointList ()

Returns the head of the joint linked list as a raw JointEdge AJO (or null when no joints are attached). The JointEdge class is not wrapped; iterate via .invokeRaw("getNext") on the AJO.
getContactList ()

Returns the head of the contact linked list as a raw ContactEdge AJO (or null when no active contacts). The ContactEdge class is not wrapped; iterate via .invokeRaw("getNext") on the AJO.
