Cocos2d检测特定精灵的触摸

Question

我有这个精灵,我试图检测用户是否触摸它并发布NSLOG.我已经阅读了一些关于在stackoverflow上检测精灵触摸的cocos2d帖子,但我有点困惑并且不太明白.任何帮助将不胜感激.我将在下面发布我的精灵.

chew = [CCSprite spriteWithFile:@"chew.png" rect:CGRectMake(0, 0, 152, 152)];
chew.position = ccp(100, 300);
[self addChild:chew];

弄清楚了

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSSet *allTouches = [event allTouches];
    UITouch* touch = [touches anyObject];
    CGPoint location = [touch locationInView: [touch view]];
    location = [[CCDirector sharedDirector] convertToGL:location];

    if (CGRectContainsPoint( [ chew   boundingBox], location)) 
    {
        NSLog(@"touched");
    }
}

为您的精神提供标记值,并在触摸事件中比较该标记值

chew = [CCSprite spriteWithFile:@"chew.png" rect:CGRectMake(0, 0, 152, 152)];
chew.position = ccp(100, 300);
chew.tag=12;
[self addChild:chew];

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event 
{
    CGPoint location = [self convertTouchToNodeSpace: touch];

    for (CCSprite *station in _objectList)
    {
        if (CGRectContainsPoint(station.boundingBox, location))
        {
             if(station.tag==12)
             {
                 DLog(@"Found Your sprite");
                 return YES;
             }
        }
    }
    return NO;
}
