我有这个泡沫，我想表现出从底部出现，但速度太快，我想速度减慢到最小的代码是..的cocos2d ccparticlesystem ....低速

emitter2.texture = [[CCTextureCache sharedTextureCache] addImage:@"Bubbles-1.png"]; 
    emitter2.position = ccp(size.width/2,-200); 
    // gravity 
    emitter2.gravity = CGPointMake(-10, 1000); 

    // angle 
    emitter2.angle = 95; 
    emitter2.angleVar = 360; 

    // speed of particles 
    emitter2.speed = 1 ;//80; 
    emitter2.speedVar = 1; 

    // radial 
    emitter2.radialAccel = -120; 
    emitter2.radialAccelVar = 0; 

    // tagential 
    emitter2.tangentialAccel = 30; 
    emitter2.tangentialAccelVar = 0; 

    // life of particles 
    emitter2.life = 2; 
    emitter2.lifeVar = 1

减轻你的重力！

emitter2.gravity = CGPointMake(-10, 1); //1000 is a bit to much for bubbles ;o)

什么呢重力做完全不是它泡的运动区......请帮助@Chakalaka –

重力做exaclty一样的地球引力做。为什么你不能飞，有时会掉到地上;）它加速了气泡 – Chakalaka

thanx很多人...我欠你 –
