Cocos2dx3.2以后使用Vector<T>取代了CCArray。
案比例如以下：
|
#ifndef __T02Vector_H__ #define __T02Vector_H__
#include "T32.h"
class T02Vector : public Layer { public: CREATE_FUNC(T02Vector);
//Cocos2dx3.2以后使用Vector取代了CCArray Vector<Sprite*> _arr;
bool init(); };
#endif |
|
编写：T02Vector.cpp |
|
#include "T02Vector.h"
//in cocos3.2 Vector取代CCArray //假设不是Ref的子类。那不能用Vector。应该用std::vector bool T02Vector::init() { Layer::init(); Sprite* sprite = Sprite::create();
//添加元素 _arr.pushBack(sprite);
//遍历 Vector<Sprite*>::iterator it; for (it = _arr.begin(); it != _arr.end(); ++it) { Sprite* s = *it; } for (auto it = _arr.begin(); it != _arr.end();++it) {
}
for (auto it: _arr) {
}
//从后往前遍历 for (auto it = _arr.rbegin(); it != _arr.rend();++it) {
}
//删除 _arr.eraseObject(sprite);
return true; } |
2 Map的使用方法（注意字符编解码的第三方库有：iconv。cocos中集成的有这方面的功能）
|
头文件：T03Map.h |
|
#ifndef __T03Map_H__ #define __T03Map_H__
#include "T32.h" class T03Map : public Layer{ public: CREATE_FUNC(T03Map); bool init(); };
#endif |
|
编写：T03Map.cpp |
|
#include "T03Map.h"
/* ValueMap是用来取代cocos2d.x的CCDictionary */ bool T03Map::init() { Layer::init();
//内容的载入 ValueMap& vm = FileUtils::getInstance()->getValueMapFromFile("about.xml");
//CCDictionary* dict = CCDictionary::createWithContentsOfFile("about.xml"); //const CCString* x = dict->valueForKey("x"); //x->intValue();
//查找 auto it = vm.find("aaa"); if (it == vm.end()) { CCLog("can not find aaa"); }
it = vm.find("people3"); it->first; //key:的类型是std::string it->second; //value:的类型是Value。相对cocos3.2.3的CCString CCLog("key is %s, value is %s", it->first.c_str(), it->second.asString().c_str());
CCLog("............................end");
vm["中文"] = "bbb";
CCLog("........start walk over"); //遍历 for (auto it = vm.begin(); it != vm.end();++it) { CCLog("key is %s,value is %s",it->first.c_str(),it->second.asString().c_str()); } CCLog("..........................end");
FileUtils::getInstance()->writeToFile(vm, "new.xml");
#if 0 // C++11 for (auto it : vm) { it.first; it.second; }
// 插入 vm["aa"] = 10;
// 訪问，这样的訪问有副作用。假设bb节点不存在，它会创建一个bb节点 Value& v = vm["bb"]; v = 100;
vm["bb"] = false; #endif return true; } |

用到的about.xml例如以下： |
|
<?xml version="1.0" encoding="UTF-8" ?> <plist> <dict> <key>people1</key> <string>许佳音工作室出品</string> <key>people2</key> <string>总监：许佳音</string> <key>people3</key> <string>程序：姜博</string> <key>people4</key> <string>美术：马俊</string> <key>people5</key> <string>改编：班级</string> </dict> </plist> |
3 T04Label的使用方法
|
头文件：T04Label.h |
|
#ifndef __T04Label_H__ #define __T04Label_H__
#include "T32.h" class T04Label :public Layer{ public: CREATE_FUNC(T04Label);
bool init(); };
#endif |
|
编写：T04Label.cpp |
|
#include "T04Label.h"
bool T04Label::init() { Layer::init();
