Cocos2d-x遊戲開發之TecturePacker的plist解析

 先要做準備工作

先下載DS_Dictionary.h和Ds_Dictionary.cpp,不多說提供下載地址

http://www.cocos2d-x.org/boards/6/topics/6125?r=13203#message-13203

文件基於pugixml下面是下載地址

下面提供test.plist作對照

下面提供一個解析的函數

 

void collision::plistParse()
{
    //Load rootDict from file, and then step into the metadata sub dict.
    DS_Dictionary rootDict;
    if(!rootDict.loadRootSubDictFromFile(bgObjectPlist))
    {
            printf("no load\n");
    }
    if(!rootDict.stepIntoSubDictWithKey("texture"))
    {
           printf("No texture\n");
    }
    //Get an int value from the subdict
    int someInt = rootDict.getIntegerForKey("height");

    printf("height    %d\n",someInt);

    someInt = rootDict.getIntegerForKey("width");

    printf("width    %d\n",someInt);
    //Step out of the sub dict and into another
    rootDict.stepOutOfSubDict();

    if(!rootDict.stepIntoSubDictWithKey("frames"))
    {
            printf("no dic\n");
    }
    for(int i=0;i<3;)
    {
        char picture[20];
        sprintf(picture,"bg_%d.png",i);
        if(!rootDict.stepIntoSubDictWithKey(picture))
        {
            i++;
            //printf("No    %s\n",picture);
            rootDict.stepOutOfSubDict();
            continue;
        }
        int x=rootDict.getIntegerForKey("x");
        int y=rootDict.getIntegerForKey("y");
        int width=rootDict.getIntegerForKey("width");
        int height=rootDict.getIntegerForKey("height");
    }
    void stepBackToRootSubDict();
}
