I got a particle effect thats is inside a group
shellParticle = new ParticleEffect();
shellParticle.load(Gdx.files.internal("shell13"),Gdx.files.internal(""));
shellParticle.getEmitters().first().setPosition(0,0);
shellParticle.scaleEffect(0.3f);
I need it to flip horizontally but it just jave the function flipY and setFlip(bool X, bool Y)
setFlip(true,false) just do nothing.
flipY() actually flips it vertically.
Also I can't subtract its own width*2 because it dosen't have...
This seems to be a lack of infrmation from part of libgx api.
The setFlip method is flipping the particle sprites (for particles which have already been emitted and future particles).
flipY() modify propieties of emmiter setting everithing to negative
but setting to negative just some of properties i get the flipX() method.
Acctualy every change you wanna do with particules you shoud do it with emmiters properties exeptiong for the x and y position.
private void flipX(){
emmiter.getAngle().setHigh(emmiter.getAngle().getHighMin(),emmiter.getAngle().getHighMax());
emmiter.getAngle().setLow(emmiter.getAngle().getLowMin(),emmiter.getAngle().getLowMax());
emmiter.getGravity().setHigh(emmiter.getGravity().getHighMin(),emmiter.getGravity().getHighMax());
emmiter.getGravity().setLow(emmiter.getGravity().getLowMin(),emmiter.getGravity().getLowMax());
emmiter.getWind().setHigh(-emmiter.getWind().getHighMin(),-emmiter.getWind().getHighMax());
emmiter.getWind().setLow(-emmiter.getWind().getLowMin(),-emmiter.getWind().getLowMax());
emmiter.getRotation().setHigh(-emmiter.getRotation().getHighMin(),-emmiter.getRotation().getHighMax());
emmiter.getRotation().setLow(-emmiter.getRotation().getLowMin(),-emmiter.getRotation().getLowMax());
emmiter.getYOffsetValue().setLow(emmiter.getYOffsetValue().getLowMin(),emmiter.getYOffsetValue().getLowMax());
emmiter.getXOffsetValue().setLow(emmiter.getXOffsetValue().getLowMin(),emmiter.getXOffsetValue().getLowMax());
}
I hope it helps someone.
