public class ParticleGroupDef
extends Object

A particle group definition holds all the data needed to construct a particle group. You can safely re-use these definitions.

Field Details

flags

public int flags

The particle-behavior flags.

groupFlags

public int groupFlags

The group-construction flags.

position

public final Vec2 position

The world position of the group. Moves the group's shape a distance equal to the value of position.

linearVelocity

public final Vec2 linearVelocity

The linear velocity of the group's origin in world co-ordinates.

angularVelocity

public float angularVelocity

The angular velocity of the group.

color

public ParticleColor color

The color of all particles in the group.

strength

public float strength

The strength of cohesion among the particles in a group with flag b2_elasticParticle or b2_springParticle.

shape

public Shape shape

Shape containing the particle group.

destroyAutomatically

public boolean destroyAutomatically

If true, destroy the group automatically after its last particle has been destroyed.

userData

public Object userData

Use this to store application-specific group data.
