Cocos2d iphone 尝试触摸阵列中的项目不工作

我有一个数组在我的触摸开始的方法（我想能够触摸精灵） 为了让它记录触摸）是我忘记做什么了还是我做错了什么

我可以将触摸记录在屏幕上，但当我触摸气泡时，什么也没有发生。 任何帮助都会很好

-(id) init
{ 
if((self=[super initWithColor:ccc4(10, 10, 10,10)]) )  //sand 101, 116, 88
{
    size = [[CCDirector sharedDirector] winSize];
    self.touchEnabled = YES;

 //other stuff here

Bubble01 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255     gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@",     [Sortingarray objectAtIndex:BubbleAnswerBubble_1_IndexValue]]];
    Bubble02 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255 gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@", [Sortingarray objectAtIndex:BubbleAnswerBubble_2_IndexValue]]];
    Bubble03 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255 gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@", [Sortingarray objectAtIndex:BubbleAnswerBubble_3_IndexValue]]];
    Bubble04 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255 gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@", [Sortingarray objectAtIndex:BubbleAnswerBubble_4_IndexValue]]];
    Bubble05 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255 gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@", [Sortingarray objectAtIndex:BubbleAnswerBubble_5_IndexValue]]];
    Bubble06 = [[Bubble alloc]initWithBubbleWithLabel:@"_Bubble.png" opacity:255 gloss:@"_Bubble_overlay.png" posX:0 posY:0 data:[NSString stringWithFormat:@"%@", [Sortingarray objectAtIndex:AnswerBubble_6_IndexValue]]];

//other stuff here

}
return self;
}

接触开始了

-(void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
//set up touches
NSSet *allTouch = [event allTouches];
UITouch *touch = [[allTouch allObjects]objectAtIndex:0];
CGPoint location = [touch locationInView:[touch view]];
location = [[CCDirector sharedDirector]convertToGL:location];

//log if touches are working if I touch the screen area
NSLog(@"touches screen");

//create an array from bubble class (CCSprites with labels, 
//I need to be able to determine which sprite was touched and run an action on it)

BubbleArray = [[NSMutableArray alloc]initWithObjects:Bubble01,
               Bubble02,
               Bubble03,
               Bubble04,
               Bubble05,
               Bubble06, 
               nil];

    for(int i = 0; i < [BubbleArray count]; i++)
    {

    Bubble *sprite = (Bubble *)[BubbleArray  objectAtIndex:i];

    //create a rect to find the position and size of the sprite 
    //BackBubble is a sprite that i'm using to detect the content size

    CGRect targetRect = CGRectMake(

           sprite.BackBubble.position.x - (sprite.BackBubble.contentSize.width/2),
           sprite.BackBubble.position.y - (sprite.BackBubble.contentSize.height/2),
           sprite.BackBubble.contentSize.width,
           sprite.BackBubble.contentSize.height);

    //use the rect and touch location to determine hit
    if(CGRectContainsPoint(targetRect, location))

    //this doesn't work possibly because Bubble class is a CClayer?

    //if(CGRectContainsPoint([sprite boundingBox], location))
    {
        selectedSprite = sprite;
        NSLog(@"touches bubble sprite");
    }
}

你的代码有点难读，但你的直接问题是为什么触摸不起作用，因为你假设你的层（气泡）有一个内容宽度和高度。如果您没有设置此选项，它就不会有此选项，这就是为什么

[sprite boundingBox]

的注释行不起作用的原因。请尝试

[sprite.BackBubble boundingBox]

。向图层添加项目不会自动调整该图层的内容大小

您还可以尝试添加以下内容：

location = [sprite convertToNodeSpace:location];

如果气泡层或后气泡在任意点移动，那么简单地将后气泡的位置添加到

CGRect

可能不起作用。先试试第一个主意，如果不行，就试试这个

希望这对你有帮助，娜塔莉。

我看不出你在场景中添加了精灵。[[[CCDirector sharedDirector]openGLView]窗口]添加子视图：]；下一步[addTarget:self action:@selector（yourfunction:）forControlEvents:uicontrolEventTouchDragins]；泡泡精灵是在init中添加的（对不起，我也会把代码放在那里）谢谢你，艾伦，嗯，对不起，我不明白。。。所以，当我创建“CGRect targetlect”时，它没有给出精灵的宽度和高度吗？（我是新来的，所以我只是想了解这一切是如何工作的，我尝试过边界框解决方案-但不幸的是，这不起作用（泡泡*）层也处理自己的触摸（拖动但不碰撞）-但这是我第一次制作自己的sprite类来进行自己的触摸检测（在游戏层，我试图让碰撞与另一个类一起工作）-因此，关于如何正确使用它的一些初期问题抱歉，我正在谈论

气泡

实例。您在代码中的注释会询问气泡的边界框是否因为它是

CCLayer

而不起作用。当您向其添加对象时，层不会设置其宽度和高度，除非您特别为该层指定宽度和高度d高度。这意味着您的

[sprite boundingBox]

将无法工作，因为对象是

气泡（声明为层），将不会有内容大小。此外，在修改后的代码中，由于未使用原始触摸位置，因此未获得正确的结果。每次迭代时，您都会将一个值转换为一个气泡的空间，并尝试将其转换为另一个气泡的空间，而不是在每次计算中使用原始触摸位置。尝试类似于
CGPoint localLocation=[sprite convertToNodeSpace:location]；
的方法，并在
CGRectContainsPoint（）中使用它
call。还有一件事。我建议你做一个或另一个，而不是两个。在你的操作代码中，你手动创建了一个CGRect来测试，这将需要将触摸位置转换为节点空间。如果你只是使用气泡背面的边界框属性，你应该可以，因为这会在内部进行父级转换。你可以应该能够拿出节点空间转换方法，我认为它会起作用。如果不行，你可以试着调试代码，看看触摸位置和矩形的值是多少，看看是否有什么奇怪的地方。你好，艾伦，谢谢你的想法！我已经将Bubble类从CCLayer更改为CCSprite（为了让内容大小和触感在游戏层注册）也尝试了你的建议，它们听起来不错，我只知道我可能对我的类的设置做了一些奇怪的事情。我会更新代码，也许你会看到错误
