CCLabelTTF在CCSequence后消失

我需要你的建议。在我的GameScene中，我有一个点标签curentPointsLabel。更新我有一个功能，但在性能updateCurentPoints（CCSequence）点标签消失！为什么？CCLabelTTF在CCSequence后消失

在初始化

_curentPointsLabel = [CCLabelTTF labelWithString:@"" dimensions:CGSizeMake(screenSize.width*0.17f, screenSize.height*0.1f) alignment:UITextAlignmentLeft fontName:@"Trebuchet MS" fontSize:15]; 
_curentPointsLabel.anchorPoint = CGPointMake(1, 1); 
_curentPointsLabel.position = ccp(screenSize.width-screenSize.height/20, screenSize.height-2*screenSize.height/20); 
_curentPointsLabel.color = ccc3(0,0,0); 
[self addChild:_curentPointsLabel];

时，我想更新点标签

我做

- (void)updateCurentPoints:(int)points { 

    if(_curentPoints+points<0) 
     _curentPoints=0; 
    else 
     _curentPoints=_curentPoints+points; 

    // [_curentPointsLabel setString:[NSString stringWithFormat:@"Score: %d",_curentPoints]]; 

    NSString * valueString=[[[NSString alloc] initWithString:[NSString stringWithFormat:@"Score: %d",_curentPoints]] retain]; 

    id sequence=[CCSequence actions: 
       [CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)1], 
       [CCCallFuncND actionWithTarget: self selector: @selector(setLabelValue:withValue:) data:(NSString*)valueString], 
       [CCBlink actionWithDuration:0.5f blinks:2], 
       [CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)3], 

       nil]; 

    [_curentPointsLabel runAction:sequence]; 

    [valueString release]; 
} 

//******************************************************************* 
-(void) setLabelValue:(id) sender withValue:(NSString*) value 
{ 
    CCLabelTTF *label=(CCLabelTTF *)sender; 
    NSString * valueString=[[[NSString alloc] initWithString:[NSString stringWithFormat:@"%@",value]] retain]; 
    [label setString:[NSString stringWithFormat:@"%@",valueString]]; 
    [valueString release]; 
} 
//******************************************************************* 
-(void) setLabelColor:(id) sender withIndex:(int)index 
{ 
    CCLabelTTF *label=(CCLabelTTF *)sender; 

    if(index==0) 
     label.color = ccc3(255,255,255);//white 
    else if(index==1) 
     label.color = ccc3(0,255,0);//green 
    else if(index==2) 
     label.color = ccc3(255,0,0);//red 
    else if(index==3) 
     label.color = ccc3(0,0,0);//black 
    NSLog(@"color:%i",index); 
}

这与您的原始问题无关，但您在代码中有'NSString'和冗余'retain'的不必要的初始化。 – Hailei 2012-04-24 05:44:04

您能否在整个过程中看到标签闪烁？还是直接消失？ – Hailei 2012-04-24 05:47:53

是的，我可以看到，但是当眨眼后标签消失 – 2012-04-24 09:48:50

添加[CCShow行动]，以确保精灵是可见的。尝试：

id sequence=[CCSequence actions: 
      [CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)1], 
      [CCCallFuncND actionWithTarget: self selector: @selector(setLabelValue:withValue:) data:(NSString*)valueString], 
      [CCBlink actionWithDuration:0.5f blinks:2], 
      [CCShow action], 
      [CCCallFuncND actionWithTarget: self selector: @selector(setLabelColor:withIndex:) data:(void*)3], 
      nil];

不断变化的眨眼次数从2到3（或其他奇数除了1）亦测试。任何一种解决方案都可以工作。
