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);
