[in] _show True to set this entity as selected.

Reimplemented in Link.

Referenced by Base::Update().

§ SetShape()

void SetShape ( ShapePtr _shape )

Set the shape for this collision.

Parameters

[in] _shape The shape for this collision object.

§ SetState()

void SetState ( const CollisionState & _state )

Set the current collision state.

Parameters

[in] The collision state.

§ SetStatic()

void SetStatic ( const bool & _static )

inherited

Set whether this entity is static: immovable.

Parameters

[in] _static True = static.

§ SetWorld()

void SetWorld ( const WorldPtr & _newWorld )

inherited

Set the world this object belongs to.

This will also set the world for all children.

Parameters

[in] _newWorld The new World this object is part of.

Referenced by Base::Update().

§ SetWorldPose()

void SetWorldPose	(	const math::Pose &	_pose,
		bool	_notify = `true`,
		bool	_publish = `true`
	)

inherited

Set the world pose of the entity.

Parameters

[in]	_pose	The new world pose.
[in]	_notify	True = tell children of the pose change.
[in]	_publish	True to publish the pose.

§ SetWorldPoseDirty()

void SetWorldPoseDirty ( )

Indicate that the world pose should be recalculated.

The recalculation will be done when Collision::GetWorldPose is called.

		const math::Vector3 &	_angular,
		bool	_updateChildren = `true`
	)

inherited

Set angular and linear rates of an physics::Entity.

Parameters

[in]	_linear	Linear twist.
[in]	_angular	Angular twist.
[in]	_updateChildren	True to pass this update to child entities.

§ StopAnimation()

virtual void StopAnimation ( )

virtualinherited

inlinevirtualinherited

§ UpdateParameters()

virtual void UpdateParameters ( sdf::ElementPtr _sdf )

virtual

Update the parameters using new sdf values.

Parameters

[in] _sdf SDF values to update from.

Reimplemented from Entity.
