如何让某些精灵在触摸后消失 - Cocos2d

我想知道一旦MainPlayer接触星星后如何消失某些精灵（星星）。

谢谢。顺便说一句，我是Cocos2d的新手，我只是为了娱乐和教育目的而做的。 谢谢。

如果您希望能够检测到cocos2d中的触摸，则需要在init方法中将isTouchEnabled属性设置为YES。您现在可以利用触摸事件。

接下来，创建新的方法：

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    //This method gets triggered every time a tap is detected 
    NSSet *allTouches = [event allTouches]; //Get all the current touches in the event 
    UITouch *aTouch = [allTouches anyObject]; //Get one of the touches, multitouch is disabled, so there is only always going to be one. 
    CGPoint pos = [aTouch locationInView:touch.view]; //Get the location of the touch 
    CGPoint ccPos = [[CCDirector sharedDirector] convertToGL:pos]; //Convert that location to something cocos2d can use 
    if (CGRectContainsPoint(yourSprite.boundingBox, ccPos)) //Method to check if a rectangle contains a point 
    { 
     yourSprite.visible = NO; //Make your sprite invisible 
    } 

} 

，你可能要采取最终有以下优势其他方法：

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event; 
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event; 
- (void)ccTouchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event; 

希望这有助于。
