有什么方法能从cocos creator构建的游戏里还原出live2d或spine动画资源?

这个游戏lIve2d里面的文件是二进制的 不清楚怎么提取 文件为bin类型 文头标识是live2d webp文件是l2d的贴图 至于uuid以及FiledID不是十六进制的转换 也不是base64转换 base64文件结尾多为== uuid的是cocos2d作为文件唯一标识的一种方法 uuid的转换的算法我找了很多网站才找到 我分享下 python代码

def uuid2uuid(base64):
    BASE64_KEYS = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/="
    BASE64_VALUES = [0 for i in range (123)]
    for i in range (123):
        BASE64_VALUES[i] = 64
    for i in range (64):
        BASE64_VALUES[ord(BASE64_KEYS[i])] = i
    BASE64Values = BASE64_VALUES
    HexChars = "0123456789abcdef"
    _t = ["","","",""]
    _tt = ["-"]
    UuidTemplate = _t +_t +_tt  +_t +_tt +_t +_tt +_t  +_tt +_t +_t +_t
    Indices = []
    _index = 0
    for v in UuidTemplate:
        if v == "":
            Indices.append(_index)
        _index += 1
    if len(base64) != 22:
        return base64
    UuidTemplate[0] = base64[0]
    UuidTemplate[1] = base64[1]
    i = 2
    j = 2
    while i < 22 :
        lhs = BASE64Values[ord(base64[i])]
        rhs = BASE64Values[ord(base64[i + 1])]
        UuidTemplate[Indices[j]] = HexChars[lhs >> 2]
        j += 1
        UuidTemplate[Indices[j]] = HexChars[((lhs & 3) << 2 )| rhs >> 4 ]
        j += 1
        UuidTemplate[Indices[j]] = HexChars[rhs & 0xF ]
        j += 1
        i += 2
    print("".join(UuidTemplate))
    return "".join(UuidTemplate)

if __name__ == '__main__':
    base64 = "a2dtc80E1EpJt286jHHckG"
    uuid2uuid(base64)


def compressUuid(fullUuid):
    BASE64_KEYS = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/="
    HexChars = "0123456789abcdef"

    if len(fullUuid) != 36:
        return fullUuid

    strs = fullUuid.split('@')
    uuid = strs[0]

    zipUuid = []
    zipUuid.append(uuid[0])
    zipUuid.append(uuid[1])
    cleanUuid = uuid.replace("-","")


    HexMap = {}
    for i in range(len(HexChars)):
        char = HexChars[i]
        HexMap[char] = i
    zip_uuid = []
    for i in range(2, 32, 3):
        left = HexMap[chr(ord(cleanUuid[i]))]
        mid = HexMap[chr(ord(cleanUuid[i + 1]))]
        right = HexMap[chr(ord(cleanUuid[i + 2]))]

        zipUuid.append(BASE64_KEYS[(left << 2) + (mid >> 2)])
        zipUuid.append(BASE64_KEYS[((mid & 3) << 4) + right])

    print("".join(zipUuid))
    return fullUuid.replace(uuid, ''.join(zip_uuid))

if __name__ == '__main__':
    fullUuid = "e0a3869f-1819-475a-b226-1a3286036488"
    compressUuid(fullUuid)

方法uuid2uuid是将22位不带-符号的uuid转换为36位带-符号的uuid
方法compressUuid则是进行相反操作 uuid名称转换可逆
通过这个转换按照json里面的uuid进行还原 不同版本coco2d的json配置不一定相同 这个游戏的spine文件的atlas以及骨骼都在json配置里面 关键字搜索"sp.SkeletonData" 需要按照uuid转换的uuid查找相应的贴图 不过文件很混乱有的是pkm格式的有的是png格式的还有的是压缩包 所以我写的脚本也有些问题就不分享了
