Thanks so much for reading!

- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch * touch = [touches anyObject];

    CGPoint location = [[CCDirector sharedDirector] convertToGL: [touch locationInView:touch.view]];
    CGRect myRect = CGRectMake(100, 120, 75, 113);

    int tjx = sprite.position.x;

    if(CGRectContainsPoint(myRect, location)) {
       tjx ++;            
    }
}

For some reason, ccTouchesEnded isn't allowing me to access my "sprite". I also tried to use CGRectMake like so :

CGRectMake( sprite.position.x, sprite.position.y, sprite.contentSize.Width, sprite.contentSize.Height)

But I couldn't access my sprites position or height. I keep getting "sprite" undeclared when it is declared in the init method, and added to the child.

Please help!! I'm sure i'm missing something really simple here.

“精灵”可能在 init 方法中本地声明，但不是该类的成员。

一种解决方案是给精灵一个标签：

sprite.tag = 123; // any arbitrary number to identify this sprite

稍后您可以使用以下命令访问该精灵：

CCSprite* sprite = [self getChildByTag:123];

它类似于通过标签删除一个孩子：http: //www.learn-cocos2d.com/knowledge-base/cocos2d-iphone-faq/learn-cocos2d-public-content/manual/cocos2d-general/14824-how-从节点场景层中删除子节点

你有没有尝试过，

  • [self sprite]
  • self.sprite
  • 检查 sprite 是否被声明为属性并且你合成了它吗？
