public class ParticleEmitter
extends Geometry
```
ParticleEmitter is a special kind of geometry which simulates a particle system.
Particle emitters can be used to simulate various kinds of phenomena, such as fire, smoke, explosions and much more.
Particle emitters have many properties which are used to control the simulation. The interpretation of these properties depends on the ParticleInfluencer that has been assigned to the emitter via setParticleInfluencer(com.jme3.effect.influencers.ParticleInfluencer). By default, the DefaultParticleInfluencer implementation is used.

    Description copied from class: Geometry
    
    This version of clone is a shallow clone, in other words, the same mesh is referenced as the original geometry. Exception: if the mesh is marked as being a software animated mesh, (bind pose is set) then the positions and normals are deep copied.
    
    Specified by:
    
    clone in interface CloneableSmartAsset
    
    Overrides:
    
    clone in class Geometry
    
    Returns:
    
    A clone of this Spatial, the scene graph in its entirety is cloned and can be altered independently of the original scene graph. Note that meshes of geometries are not cloned explicitly, they are shared if static, or specially cloned if animated.

    Deprecated. This method is deprecated. Use ParticleEmitter.getParticleInfluencer().setVelocityVariation(variation); instead.
    
    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 specified in ParticleInfluencer.setInitialVelocity(com.jme3.math.Vector3f), and 1 means particles are to spawn with a completely random velocity.
  - emitAllParticles
```
public void emitAllParticles()
```
    Instantly emits all the particles possible to be emitted. Any particles which are currently inactive will be spawned immediately.
  - emitParticles
```
public void emitParticles(int num)
```
    Instantly emits available particles, up to num.
    
    Parameters:
    
    num - the maximum number of particles to emit
  - killAllParticles
```
public void killAllParticles()
```
    Instantly kills all active particles, after this method is called, all particles will be dead and no longer visible.
  - killParticle
```
public void killParticle(int index)
```
    Kills the particle at the given index.
    
    Parameters:
    
    index - The index of the particle to kill

    getParticles()
  - updateParticle
```
protected void updateParticle(Particle p,
                              float tpf,
                              Vector3f min,
                              Vector3f max)
```
  - setEnabled
```
public void setEnabled(boolean enabled)
```
    Set to enable or disable the particle emitter
    When a particle is disabled, it will be "frozen in time" and not update.
    
    Parameters:
    
    enabled - True to enable the particle emitter
  - isEnabled
```
public boolean isEnabled()
```
    Check if a particle emitter is enabled for update.
    
    Returns:
    
    True if a particle emitter is enabled for update.
    
    See Also:
    
    setEnabled(boolean)
  - updateFromControl
```
public void updateFromControl(float tpf)
```
    Callback from Control.update(), do not use.
    
    Parameters:
    
    tpf - time per frame (in seconds)
  - preload
```
public void preload(RenderManager rm,
                    ViewPort vp)
```
