Constructor Detail

ParticleEffect

public ParticleEffect()

ParticleEffect

public ParticleEffect(ParticleEffect effect)

Method Detail

start

public void start()

reset

public void reset()

Resets the effect so it can be started again like a new effect. Any changes to scale are reverted. See reset(boolean).

reset

public void reset(boolean resetScaling)

Resets the effect so it can be started again like a new effect.

Parameters:

resetScaling - Whether to restore the original size and motion parameters if they were scaled. Repeated scaling and resetting may introduce error.

update

public void update(float delta)

draw

public void draw(Batch spriteBatch)

draw

public void draw(Batch spriteBatch,
                 float delta)

allowCompletion

public void allowCompletion()

isComplete

public boolean isComplete()

setDuration

public void setDuration(int duration)

setPosition

public void setPosition(float x,
                        float y)

setFlip

public void setFlip(boolean flipX,
                    boolean flipY)

flipY

public void flipY()

getEmitters

public Array<ParticleEmitter> getEmitters()

findEmitter

public ParticleEmitter findEmitter(java.lang.String name)

Returns the emitter with the specified name, or null.

preAllocateParticles

public void preAllocateParticles()

Allocates all emitters particles. See ParticleEmitter.preAllocateParticles()

                 TextureAtlas atlas)

load

public void load(FileHandle effectFile,
                 TextureAtlas atlas,
                 java.lang.String atlasPrefix)

newEmitter

protected ParticleEmitter newEmitter(ParticleEmitter emitter)

loadTexture

protected Texture loadTexture(FileHandle file)

dispose

public void dispose()

Disposes the texture for each sprite for each ParticleEmitter.

Specified by:

dispose in interface Disposable

getBoundingBox

public BoundingBox getBoundingBox()

Returns the bounding box for all active particles. z axis will always be zero.

scaleEffect

public void scaleEffect(float scaleFactor)

Permanently scales all the size and motion parameters of all the emitters in this effect. If this effect originated from a ParticleEffectPool, the scale will be reset when it is returned to the pool.

scaleEffect

public void scaleEffect(float scaleFactor,
                        float motionScaleFactor)

Permanently scales all the size and motion parameters of all the emitters in this effect. If this effect originated from a ParticleEffectPool, the scale will be reset when it is returned to the pool.

scaleEffect

public void scaleEffect(float xSizeScaleFactor,
                        float ySizeScaleFactor,
                        float motionScaleFactor)

Permanently scales all the size and motion parameters of all the emitters in this effect. If this effect originated from a ParticleEffectPool, the scale will be reset when it is returned to the pool.

setEmittersCleanUpBlendFunction

public void setEmittersCleanUpBlendFunction(boolean cleanUpBlendFunction)

Sets the cleansUpBlendFunction parameter on all ParticleEmitters currently in this ParticleEffect.

IMPORTANT: If set to false and if the next object to use this Batch expects alpha blending, you are responsible for setting the Batch's blend function to (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) before that next object is drawn.

Parameters:

cleanUpBlendFunction -
