Cocos2d-x游戏开发之TecturePacker的plist解析

 先要做准备工作

先下载DS_Dictionary.h和Ds_Dictionary.cpp,不多说提供下载地址

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

文件基于pugixml下面是下载地址

下面提供test.plist作对照

下面提供一个解析的函数

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(); 
}
