libgdx 粒子效果旋转 [英] libgdx particleEffect rotation

问题描述

我用 libgdx 在我的 android 设备上引火:

I draw fire on my android device with libgdx:

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?

Can I rotate, set speed or scale my effect programmatically?

推荐答案

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

Yes. Check out the ParticleEmitterTest: https://github.com/libgdx/libgdx/blob/master/tests/gdx-tests/src/com/badlogic/gdx/tests/ParticleEmitterTest.java

您只需要获取一个 ParticleEmitter:

You just need to obtain a ParticleEmitter:

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