cocos2dx 读取json及解析

@H_301_0@ball.json 数据如下：

@H_301_0@

"entities":[

{
"entity":{
"TapOpposite":0,
"Interval":0.95,
"BallNum":1
}
},248)"> {
"entity":{
"TapOpposite":0,108); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> "Interval":0.91,248)"> "BallNum":2
}
},108); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> "BallNum":3
]
}

@H_301_0@

@H_301_0@在cocos2dx中json的读取是用的rapidjson,包含在cocostudio工程中。所以我们要先引入#include "cocostudio/CocoStudio.h"

@H_301_0@

voidGameWorld::readJson()

//json文档
rapidjson::Document_doc;
boolbRet=false;
ssize_tsize=0;
unsignedchar*pBytes=NULL;
do{
pBytes=cocos2d::CCFileUtils::sharedFileUtils()->getFileData("ball.json","r",&size);
CC_BREAK_IF(pBytes==NULL||strcmp((char*)pBytes,"")==0);
std::stringload_str((const CC_SAFE_DELETE_ARRAY(pBytes);
_doc.Parse<0>(load_str.c_str());
CC_BREAK_IF(_doc.HasParseError());
//生成json文档对像
if(!_doc.IsObject())
return;
//是否有此成员
if(!_doc.HasMember("entities"))
//通过[]取成员值,再根据需要转为array,int,double,string
constrapidjson::Value&pArray=_doc["entities"];
//是否是数组
if(!pArray.IsArray())
return;
for(rapidjson::SizeTypei=0;i<pArray.Size();i++)
constrapidjson::Value&p=pArray[i];
if(p.HasMember("entity"))
constrapidjson::Value&valueEnt=p["entity"];
if(valueEnt.HasMember("TapOpposite")&&valueEnt.HasMember("Interval")&&valueEnt.HasMember("BallNum"))
constrapidjson::Value&tapOpposite=valueEnt["TapOpposite"];
inttapOp=tapOpposite.GetInt();//得到int值
constrapidjson::Value&interval=valueEnt["Interval"];
floatinter=interval.GetDouble();//得到float,double值
constrapidjson::Value&ballNum=valueEnt["BallNum"];
intball=ballNum.GetInt(); ballParamparam;
param.tapOp=tapOp;
param.inter=inter;
param.ballIndex=ball;
m_ballParamVec.push_back(param);
else
bRet=true;
}while(0);
}
