如何为CCSprite应用动画

Question

刚刚开始一个cocos2d游戏。在那里检查碰撞，以及是否发生碰撞使用以下代码创建动画。动画代码被调用但不显示任何动画。什么是这个错误请帮我解决。

-(void)check_collision:(ccTime)dt 
{ 
    for(PolygonSprite *sprite in _cache) 
    { 
    if(CGRectIntersectsRect(sprite.boundingBox,monkey.boundingBox)) 
    { 
     if(sprite != monkey) 
     { 
     NSLog(@"collision collision collision.......%@",sprite); 
     id s2 = [CCScaleTo actionWithDuration:0.5 scaleX:1.5 scaleY:1.5]; 
     id fun = [CCCallFuncN actionWithTarget:self selector:@selector(spriteDone:)]; 
     [sprite runAction:[CCSequence actions:s2,fun,nil]]; 
     [self unschedule:@selector(check_collision:)]; 
    } 
    } 
} 

}

试试这个，

[self schedule:@selector(check_collision:)interval:1]; 

-(void) check_collision: (ccTime) t 
{ 
    for(PolygonSprite *sprite in _cache) 
    { 
     if(CGRectIntersectsRect(sprite.boundingBox,monkey.boundingBox)) 
     { 
      if(sprite != monkey) 
      { 
       id s2 = [CCScaleTo actionWithDuration:0.1 scaleX:2 scaleY:2]; 
       id fun = [CCCallFuncN actionWithTarget:self selector:@selector(spriteDone)]; 
       [car.sprite runAction:[CCSequence actions:s2,fun,nil]]; 
       [self unschedule:@selector(check_collision:)]; 
      } 
     } 
    } 
} 

-(void) spriteDone 
{ 
    // Function logic goes here.. 
} 

希望这有助于..谢谢你
