Methods

addContact(Particle particleA, Particle particleB) → void

computeDepthForGroup(ParticleGroup group) → void

computeParticleCollisionEnergy() → double

createParticle(Particle particle) → void

createParticleGroup(ParticleGroupDef groupDef) → ParticleGroup

destroyParticle(Particle particle, {required bool callDestructionListener}) → void

destroyParticlesInGroup(ParticleGroup group, {bool callDestructionListener = false}) → void

destroyParticlesInShape(Shape shape, Transform xf, {bool callDestructionListener = false}) → void

Destroy particles inside a shape. In addition, this function immediately destroys particles in the shape in contrast to DestroyParticle() which defers the destruction until the next simulation step.

getCriticalVelocitySquared(TimeStep step) → double

joinParticleGroups(ParticleGroup groupA, ParticleGroup groupB) → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.
