在xcode中拖放CCSprite

在我的应用程序中，我使用了CCSprites。它们以正确的格式和ccTouchesBegan函数正确定义。然后我添加了拖放代码。他们是在xcode中拖放CCSprite

- (void)selectSpriteForTouch:(CGPoint)touchLocation { 
CCSprite * newSprite = nil; 
NSMutableArray *movableSprites=[[NSMutableArray alloc] initWithObjects:Tocken1,Tocken2,Tocken3]; 
    for (CCSprite *sprite in movableSprites) 
    { 
     if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) 
     {    
      newSprite = sprite; 
      break; 
     } 
}  
if (newSprite != selSprite) { 
    [selSprite stopAllActions]; 
    [selSprite runAction:[CCRotateTo actionWithDuration:0.1 angle:0]]; 
    CCRotateTo * rotLeft = [CCRotateBy actionWithDuration:0.1 angle:-4.0]; 
    CCRotateTo * rotCenter = [CCRotateBy actionWithDuration:0.1 angle:0.0]; 
    CCRotateTo * rotRight = [CCRotateBy actionWithDuration:0.1 angle:4.0]; 
    CCSequence * rotSeq = [CCSequence actions:rotLeft, rotCenter, rotRight, rotCenter, nil]; 
    [newSprite runAction:[CCRepeatForever actionWithAction:rotSeq]];    
    selSprite = newSprite; 
} 
} 
- (CGPoint)boundLayerPos:(CGPoint)newPos { 
CGSize winSize = [CCDirector sharedDirector].winSize; 
CGPoint retval = newPos; 
retval.x = MIN(retval.x, 0); 
retval.x = MAX(retval.x, -background.contentSize.width+winSize.width); 
retval.y = self.position.y; 
return retval; 
} 
- (void)panForTranslation:(CGPoint)translation {  
if (Tocken1) { 
    CGPoint newPos = ccpAdd(Tocken1.position, translation); 
    Tocken1.position = newPos; 
} else { 
    CGPoint newPos = ccpAdd(self.position, translation); 
    self.position = [self boundLayerPos:newPos];  
} 
} 
- (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event 
{  
CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; 

CGPoint oldTouchLocation = [touch previousLocationInView:touch.view]; 
oldTouchLocation = [[CCDirector sharedDirector] convertToGL:oldTouchLocation]; 
oldTouchLocation = [self convertToNodeSpace:oldTouchLocation]; 

CGPoint translation = ccpSub(touchLocation, oldTouchLocation);  
[self panForTranslation:translation];  
}

现在当我点击精灵程序终止与下面的错误代码。

:(没有回答.... – priya 2012-02-23 09:15:38

您没有在图层中实现方法“ccTouchBegan”。父类方法告诉你它需要被覆盖。

原因： '图层＃ccTouchBegan重写我的'

这样实现：

- (BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event 
{ 
    // add code to handle touch... 

    // return YES to claim all touches when they begin 
    // or return only YES for those touches you want to deal with 
    return YES; 
}

更新：

您可以看到该错误消息来了从如果您在“.../libs/cocos2d/...”文件夹中查看文件“CCLayer.m”（假设您有一个典型的项目结构再从模板等），让这个错误代码是在行〜257（cocos2d的1.0.1版），看起来像这样：

-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event 
{ 
    NSAssert(NO, @"Layer#ccTouchBegan override me"); 
    return YES; 
} 
#endif

我添加了这一点。。:( – priya 2012-02-24 05:13:43

检查你的'ccTouchBegan'方法*是否真正*在正确的类中实现。这部分从错误消息清楚地表明，该方法发送到CCLayer父类：“原因：'层＃ccTouchBegan覆盖我'” – phlebotinum 2012-02-24 11:49:43

我删除了该代码并添加了一些教程，现在它开始工作。我不知道它出错了。无论如何，谢谢你robo :) – priya 2012-02-24 11:52:27
