我在触摸开始方法中有一个数组（我希望能够触摸精灵 并且对于它来说，触摸它是否有什么东西我忘了做或做错了什么？
我可以在屏幕上记录触摸，但当我触摸气泡时没有任何反应。 任何帮助都会很棒。
-(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;
}
的touchesBegan
-(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");
}
}
}
任何洞察力都可以帮助我理解我做错了什么。 干杯：）
新的数组代码（通过自定义类获取精灵的高度和宽度
for(int i = 0; i < [DragItems count]; i++)
{
Bubble *sprite = (Bubble *)[BubbleArray objectAtIndex:i];
location = [sprite convertToNodeSpace:location];
if(CGRectContainsPoint([sprite.BackBubble boundingBox], location))
{
selectedSprite = sprite;
NSLog(@"touches bubble");
}

答案 0 :(得分：1)
您的代码有点难以阅读，但您对触摸不起作用的直接问题是因为您假设您的图层（气泡）具有内容宽度和高度。如果你没有设置它，它就没有它，这就是你[sprite boundingBox]的注释掉行不起作用的原因。试试[sprite.BackBubble boundingBox]。向图层添加项目不会自动调整该图层的内容大小。
您可以尝试的另一件事是添加：
location = [sprite convertToNodeSpace:location];
如果您的泡泡层或后泡泡在任何位置移动，那么只需将后泡泡的位置添加到CGRect就不太可能。首先尝试第一个想法然后尝试这个，如果它不起作用。
希望这能帮助你娜塔莉。
