objective-c - 创建粒子爆发

Question

目前在我正在构建的测试应用程序中，我想创建两个物体碰撞时出现的粒子爆发。主要对象将保持可见，而第二个对象将被移除。代替第二个对象（已移除）将是粒子爆发。我应该如何设置？你能指导我完成在 cocos2d 中创建这个粒子爆发的步骤吗？谢谢！

heres the code i have for 3 emitters:

emitter = [[CCParticleGalaxy alloc] init];
emitter.texture = [[CCTextureCache sharedTextureCache] addImage:@"stars.png"];
emitter.startColor = ccc4FFromccc3B(ccRED);
emitter.endColor = ccc4FFromccc3B(ccGREEN);
emitter.life = 1;
emitter.duration = .5;

emitter2 = [[CCParticleGalaxy alloc] init];
emitter2.texture = [[CCTextureCache sharedTextureCache] addImage:@"stars.png"];
emitter2.startColor = ccc4FFromccc3B(ccRED);
emitter2.endColor = ccc4FFromccc3B(ccGREEN);
emitter2.life = 1;
emitter2.duration = .5;

emitter3 = [[CCParticleGalaxy alloc] init];
emitter3.texture = [[CCTextureCache sharedTextureCache] addImage:@"stars.png"];
emitter3.startColor = ccc4FFromccc3B(ccRED);
emitter3.endColor = ccc4FFromccc3B(ccGREEN);
emitter3.life = 1;
emitter3.duration = .5;

Defined as in .h

CCParticleGalaxy *emitter;
CCParticleGalaxy *emitter2;
CCParticleGalaxy *emitter3;
CCParticleGalaxy *emitter4;

then add it to your layer when needed and set the position

emitter.position = ccp(sprite.position.x, sprite.position.y);
[self addChild:emitter];

instead of CCParticleGalaxy you can change that to CCParticleExplosion, CCParticleFire, CCParticleFireworks, CCParticleFire, ect... just experiment and find whats best for you
