Iphone cocos2d中粒子系统的启动和停止

请，我想问一下我如何在iOS/cocos2d中启动一个粒子系统，让它运行一段时间，比如说10秒，然后让它停止

一个小的代码片段或例子，将作为一个指南将不胜感激

谢谢

假设ps是您的粒子系统，您可以按如下方式启动和停止它：

[ps resetSystem]; // starts, newly created effects are already running
[ps stopSystem];  // stops

等待10秒可以按10秒的间隔安排选择器。

[ps resetSystem]; // starts, newly created effects are already running
[ps stopSystem];  // stops

等待10秒可以安排一个选择器，间隔10秒。

希望它有帮助：

-(void)addParticles
{
  [particles resetSystem]; //restarts particles
}

-(void)playParticles //call this later somewhere in your code e.g in touches began [self playParticles];
{
  id playParticles = [CCCallFuncN actionWithTarget:self selector:@selector(addParticles)];
  id stopParticles = [CCCallFuncN actionWithTarget:self selector:@selector(stopParticles)];
  id wait = [CCActionInterval actionWithDuration:3];
  CCSequence *Particlesbegin = [CCSequence actions:wait,playParticles,wait,stopParticles, nil];
  [self runAction: Particlesbegin];
}

-(void)stopParticles
 {
  [particles stopSystem];
 }



//in touches began
if(CGRectContainsPoint(Btn.boundingBox, location))
{
    [self playParticles];
}
