android – libgdx particleEffect旋转

我用libgdx在我的 android设备上画火：

ParticleEffect effect;
ParticleEffectPool fireEffectPool;
Array<PooledEffect> effects = new Array<PooledEffect>();

@Override
public void create() 
{
    ...
    effect = new ParticleEffect();
    effect.load(Gdx.files.internal("particles/fire01.p"),Gdx.files.internal("image"));
    effect.setFlip(true,false);
    fireEffectPool = new ParticleEffectPool(effect,1000,3000);

    PooledEffect myEffect = fireEffectPool.obtain();
    myEffect.setPosition(200,400);
    effects.add(myEffect);
    ...
}

我可以通过编程方式旋转,设置速度或缩放效果吗？

解决方法

是.查看ParticleEmitterTest： https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/ParticleEmitterTest.java

你只需要获得一个ParticleEmitter：

emitter = effect.getEmitters().first();
emitter.getScale().setHigh(5,20);
