Cocos2d触摸，一些错误

Question

我写了下面的程序，它必须做到以下几点：当用户触摸移动精灵时，它必须从场景中移除。

但是，当我运行我的代码时，会发生以下情况：当我触摸最高的精灵时，它会消失，而它的邻居。我该如何解决它？

这是代码。

UPD：我测试了这个代码更小的* .png文件，并且一切工作正常。但是在更大的* .png文件（像200x200像素，iPhone模拟器一样），我有一个bug：对象与其最近的邻居touchEvent删除。

#import <Foundation/Foundation.h> 
#import "cocos2d.h" 


@interface GameplayLayer : CCLayer { 

    NSMutableArray *arrayOfSprites; 

} 
@end 
    #import "GameplayLayer.h" 
@implementation GameplayLayer 
    -(id)init 
{ 
    self = [super init]; 
    self.isTouchEnabled=YES; 
    arrayOfSprites=[[NSMutableArray alloc] init]; 

    if (self != nil) 
    { 
     int j=100; 

     for (int i=0; i<=2; i++) { 
      [arrayOfSprites addObject:[CCSprite spriteWithFile:@"sv_anim_1-hd.png"]]; 
      [[arrayOfSprites objectAtIndex:i] setPosition:CGPointMake(j,j)]; 
      [self addChild:[arrayOfSprites objectAtIndex:i] z:0 tag:i]; 
      j+=100; 
     } 
     [self startRunning]; 
    } 
    return self;         
} 
    -(void)startRunning 
{ 
    CGSize screenSize=[[CCDirector sharedDirector] winSize]; 
    for (CCSprite * currentSprite in arrayOfSprites) 
    { 
     [currentSprite runAction:[CCMoveTo actionWithDuration:10 position:CGPointMake(screenSize.height,screenSize.width/2)]]; 
    } 
} 
     -(void) registerWithTouchDispatcher 
    { 
     [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 
                swallowsTouches:YES]; 
    } 

     -(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { 
     return YES; 
    } 

     -(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event { 
     CGPoint locationOfTouch=[self convertTouchToNodeSpace: touch]; 

     for (CCSprite *currentSprite in arrayOfSprites) 
     { 
      if (CGRectContainsPoint(currentSprite.boundingBox, locationOfTouch)) 
      { 
       NSLog(@"Sprite was touched"); 
       [self removeChild:currentSprite cleanup:YES]; 
      } 
     } 

    } 
    @end

试试这个功能：

-(CGRect)getSpriteRect:(CCNode *)inSprite 
{ 
    CGRect sprRect = CGRectMake(
           inSprite.position.x - inSprite.contentSize.width*inSprite.anchorPoint.x, 
           inSprite.position.y - inSprite.contentSize.height*inSprite.anchorPoint.y, 
           inSprite.contentSize.width, 
           inSprite.contentSize.height 
           ); 

    return sprRect; 
} 


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


    for (CCSprite *currentSprite in arrayOfSprites) 
    { 
     CGRect rect = [self getSpriteRect:currentSprite]; 

     if (CGRectContainsPoint(rect, location)) 
     { 
      NSLog(@"Sprite was touched"); 
      [self removeChild:currentSprite cleanup:YES]; 
     } 
    } 
}
