com.jme3.effect.influencers.EmptyParticleInfluencer

All Implemented Interfaces:

ParticleInfluencer, Savable, JmeCloneable, java.lang.Cloneable

public class EmptyParticleInfluencer
extends java.lang.Object
implements ParticleInfluencer

This influencer does not influence particle at all. It makes particles not to move.

Method Detail

write

public void write(JmeExporter ex)
           throws java.io.IOException

Specified by:

write in interface Savable

Throws:

java.io.IOException

read

public void read(JmeImporter im)
          throws java.io.IOException

Specified by:

read in interface Savable

Throws:

java.io.IOException

influenceParticle

public void influenceParticle(Particle particle,
                              EmitterShape emitterShape)

Description copied from interface: ParticleInfluencer

This method influences the particle.

Specified by:

influenceParticle in interface ParticleInfluencer

Parameters:

particle - particle to be influenced

emitterShape - the shape of it emitter

setInitialVelocity

public void setInitialVelocity(Vector3f initialVelocity)

Specified by:

setInitialVelocity in interface ParticleInfluencer

Parameters:

initialVelocity - Set the initial velocity a particle is spawned with, the initial velocity given in the parameter will be varied according to the velocity variation set in ParticleEmitter.setVelocityVariation(float). The particle will move with this velocity unless it is affected by gravity.

getInitialVelocity

public Vector3f getInitialVelocity()

Description copied from interface: ParticleInfluencer

This method returns the initial velocity.

Specified by:

getInitialVelocity in interface ParticleInfluencer

Returns:

the initial velocity

setVelocityVariation

public void setVelocityVariation(float variation)

Specified by:

setVelocityVariation in interface ParticleInfluencer

Parameters:

variation - Set the variation by which the initial velocity of the particle is determined. variation should be a value from 0 to 1, where 0 means particles are to spawn with exactly the velocity given in ParticleEmitter.setInitialVelocity(com.jme3.math.Vector3f), and 1 means particles are to spawn with a completely random velocity.

getVelocityVariation

public float getVelocityVariation()

Description copied from interface: ParticleInfluencer

This method returns the velocity variation.

Specified by:

getVelocityVariation in interface ParticleInfluencer

Returns:

the velocity variation

clone

public ParticleInfluencer clone()

Description copied from interface: ParticleInfluencer

This method clones the influencer instance.

Specified by:

clone in interface ParticleInfluencer

Overrides:

clone in class java.lang.Object

Returns:

cloned instance

jmeClone

public java.lang.Object jmeClone()

Called internally by com.jme3.util.clone.Cloner. Do not call directly.

Specified by:

jmeClone in interface JmeCloneable

Returns:

a new instance

cloneFields

public void cloneFields(Cloner cloner,
                        java.lang.Object original)

Called internally by com.jme3.util.clone.Cloner. Do not call directly.

Specified by:

cloneFields in interface JmeCloneable

Parameters:

cloner - The cloner that is performing the cloning operation. The cloneFields method can call back into the cloner to make clones of its subordinate fields.

original - The original object from which this object was cloned. This is provided for the very rare case that this object needs to refer to its original for some reason. In general, all of the relevant values should have been transferred during the shallow clone and this object need merely clone what it wants.
