Detailed Description

Represents constant volume joint that tries to keep the volume enclosed by a group of bodies constant. This joint is similar to connecting multiple springs between the bodies in order to maintain the volume inside their position constant. This is the joint used to create the FBlob body.

Constructor & Destructor Documentation

◆ FConstantVolumeJoint()

FConstantVolumeJoint.FConstantVolumeJoint ( )

Constructs an constant volume joint. It creates an empty joint, before adding the joint to the world use addBody to add bodies to the joint and to define the initial and target volume of the joint.

Member Function Documentation

◆ addBody()

void FConstantVolumeJoint.addBody ( FBody  b)

Adds a body to the joint. This method must be called before adding the joint to the world.

Parameters
bbody to be added

◆ getBodies()

ArrayList FConstantVolumeJoint.getBodies ( )

Return the group of bodies that are connected by this joint.

Returns
list of bodies (ArrayList of FBody) connected by the joint

◆ setDamping()

void FConstantVolumeJoint.setDamping ( float  damping)

Sets the damping of the springs used to maintain the volume defined by the vertices constant. This method must be called before adding the joint to the world.

Parameters
dampingthe damping of the springs of the constant volume joint

◆ setFrequency()

void FConstantVolumeJoint.setFrequency ( float  frequency)

Sets the frequency of the springs used to maintain the volume defined by the vertices constant. This method must be called before adding the joint to the world.

Parameters
frequencythe frequency of the springs of the constant volume joint
