Question

我是Cocos2d的新手，在过去的3天里一直试图加载一个多包装精灵表动画。

我无法找到教程或工作示例，看了raywenderlich.com，发现这篇文章讨论了单个文件精灵表动画：Example 1

此Example 2不起作用：

那么如何加载一个multipack sprite表？

由于

我添加了部分有效的代码。问题是： 1）文件-ipadhd和-hd无法按预期识别（在其他动画中，它们被识别，因此AppDelegate中的设置为Ok） 2）当加载multipack动画时，我得到一个例外文件示例：apple0.png，apple0.plist，apple0-hd.png，apple0-hd.plist，apple1-hd.png，apple1-hd.plist，apple0-ipadhd.png，apple0-ipadhd.plist，apple1-ipadhd .png，apple1-ipadhd.plist

        NSFileManager *fileManager = [NSFileManager defaultManager];
        BOOL exists = YES;
        int plistIndex = -1;
        int tmpPlistIndex;
        NSMutableArray *availablePLists = [NSMutableArray array];

        NSMutableArray *imageFrames = [NSMutableArray array];
        NSMutableArray *spriteSheets = [NSMutableArray array];
        frameCount = 0;

        do {
            plistIndex +=1;
            NSString* plistFileName = [NSString stringWithFormat:@"%d%@",plistIndex,item.fileName];

            plistFileName = [[NSBundle mainBundle] pathForResource:plistFileName ofType:@"plist"];



            plistPath = plistFileName;
            [availablePLists addObject:plistPath];
            plistDict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
            frames = [plistDict objectForKey:@"frames"];
            frameCount += frames.count;

我在cocos2d-html5和cocos2dx中使用js绑定但是 - 我的答案应该仍然适用。据我所知，cocos2d中没有对multipack的特殊处理，这是Texture packer中可用的构造。您应该加载所有plist + png，就像它们是单个节点一样。从那里，你应该能够从任何一个创建精灵和动画，因为它们都在缓存中。

代码：

jc.makeSpriteWithMultipackPlist = function(plists, pngs, startFrame){
    var sprite = new cc.Sprite();
    for(var i =0;i<plists.length;i++){
        var plist = plists[i];
        var png = pngs[i];
        if (!jc.parsed[plist]){
            cc.SpriteFrameCache.getInstance().addSpriteFrames(plist);
            cc.SpriteBatchNode.create(png);
            jc.parsed[plist]=true;
        }
    }

    var frame = cc.SpriteFrameCache.getInstance().getSpriteFrame(startFrame);
    if (!frame){
        throw "Frame: " + startFrame +  " not in cache.";
    }
    sprite.initWithSpriteFrame(frame);
    sprite.retain();
    return sprite;
}
