Question

我使用了来自http://www.raywenderlich.com/25736/how-to-make-a-simple-iphone-game-with-cocos2d-2-x-tutorial的cocos2d游戏教程。在我将得分添加到得分标签后，得分增加但是之前的得分没有被删除，新得分被添加到早期得分的标签之上

代码：

CGSize winSize = [[CCDirector sharedDirector] winSize];
CCLabelTTF * label1 = [CCLabelTTF labelWithString:@"_monsterdestroyed" fontName:@"Arial" fontSize:32];
score=score + 2;

[label1 setString:[NSString stringWithFormat:@"%d",score]];

label1.color = ccc3(0,0,0);
label1.position = ccp(winSize.width/2, winSize.height/2);
[self addChild:label1];

Answer 1

我猜你在更新方法中做了这一切，每次更新时都添加了label1标签。您可能需要在.h文件中为分数label1创建一个iVar，在init中初始化它，如下所示：

in .h

CCLabelTTF *label1;

in .m

-(id) init {
    if (self = [super init]) {
        // your existing code, add the following
        CGSize winSize = [[CCDirector sharedDirector] winSize];

        label1 = [CCLabelTTF labelWithString:@"0" fontName:@"Arial" fontSize:32];
        label1.color = ccc3(0,0,0);
        label1.position = ccp(winSize.width/2, winSize.height/2);
        [self addChild:label1];  
   }     
 }


 // where you update the score
 score = score + 2;
 [label1 setSting:[NSString stringWithFormat:"%i", score];

显示分数重叠
