Question

我是cocos2d的初学者，但我在Objective-C和iphoneSdk方面有一些经验。但我的应用程序中有一个问题，我无法弄清楚错误是什么..

我有一个CCLayer（动漫），它向玩家显示一个小动画，然后它启动另一个CCLayer（等级）：

动画：

-(id) init{

    if( (self=[super init])) {

CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache]; 
[frameCache addSpriteFramesWithFile:@"Anime.plist"];  



CCSprite * backgound = [CCSprite spriteWithSpriteFrameName:@"Back.png"];
backgound.anchorPoint=ccp(0,0);
[self addChild:backgound z:-1];


CCSprite *body = [CCSprite spriteWithSpriteFrameName:@"Body1.png"];
[self addChild:body z:0];

CCSprite *bMoved = [CCSprite spriteWithSpriteFrameName:@"Gigante1.png"];
[self addChild:bMoved z:1];      


NSMutableArray *nuvemAnim = [[NSMutableArray alloc] init];
        for (int i = 1; i < 41; i++) {
            NSString *frameNames = [NSString stringWithFormat:@"Gigante%i.png",i];
            [nuvemAnim addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] 
                                  spriteFrameByName:frameNames]];

        }    


        CCAnimation *gigAnim = [CCAnimation animationWithFrames:nuvemAnim  delay:1.0f/24.0f];
        CCAnimate* animate = [CCAnimate actionWithAnimation:gigAnim];   


        [bMoved runAction:[CCSequence actions:
                         [CCDelayTime actionWithDuration:1],
                         animate,
                         [CCDelayTime actionWithDuration:1],
                         [CCCallFunc actionWithTarget:self selector:@selector(changeCCScene)],
                           nil]];


    }
return self;

在Level I中，使用CCSpriteFrameCache创建角色动画

等级：

-(id) init{
if( (self=[super init])) {

    self.isTouchEnabled=YES;


    CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache]; 
   [frameCache addSpriteFramesWithFile:@"Level3.plist"]; 

    CCSprite * backgound = [CCSprite spriteWithSpriteFrameName:@"Fundo9.png"];
    backgound.anchorPoint=ccp(0,0);
    [self addChild:backgound z:-1];


    CCSprite man = [CCSprite spriteWithSpriteFrameName:@"Man1.png"];
    [self man z:0];


    eAnim = [[NSMutableArray alloc] init];
    for (int i = 2; i < 178; i++) {
        NSString *frameNames = [NSString stringWithFormat:@Man%i.png",i];
        [eAnim addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] 
                                spriteFrameByName:frameNames]];

    }

但是在控制台中无限制地为所有帧提供了这种类型的错误

2012-04-03 23:37:51.987 GigV1[1432:10a03] cocos2d: WARNING: an alias with name Man12.png already exists
2012-04-03 23:37:51.988 GigV1[1432:10a03] cocos2d: WARNING: an alias with name Man155.png already exists

为什么会发生这种情况？

由于

Answer 1

此行中缺少引号：

NSString *frameNames = [NSString stringWithFormat:@Man%i.png",i];

应该是@之后和Man%i

之前的开头报价

Answer 2

您正在从Anime.plist和Level3.plist中加载精灵帧：

CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache]; 
[frameCache addSpriteFramesWithFile:@"Anime.plist"]; 

[frameCache addSpriteFramesWithFile:@"Level3.plist"];

此警告表示您正在添加更多具有相同名称的精灵帧：

WARNING: an alias with name Man12.png already exists

要解决此问题，您有三种选择：

确保在两个不同的纹理图集中使用相同的精灵框架名称（相同的图像）
从加载来自另一个纹理图集的精灵帧之前从缓存中卸载精灵帧
忽略警告

错误更改CCScene
