cocos2dx3.3线程简单使用
|
//HelloWorld声明添加变量
#ifndef __HELLOWORLD_SCENE_H__ #define __HELLOWORLD_SCENE_H__ #include "cocos2d.h" class HelloWorld : public cocos2d::Layer { public: // there's no 'id' in cpp,so we recommend returning the class instance pointer static cocos2d::Scene* createScene();
// Here's a difference. Method 'init' in cocos2d-x returns bool,instead of returning 'id' in cocos2d-iphone virtual bool init(); void runStartMyThread(); void runStartMyThread2(); // a selector callback void menuCloseCallback(cocos2d::Ref* pSender); // implement the "static create()" method manually CREATE_FUNC(HelloWorld);
private: int m_nStore = 50; std::mutex m_mutex; ／／／／互斥变量，用来锁定线程
}; #endif // __HELLOWORLD_SCENE_H__
void HelloWorld::runStartMyThread() { while (m_nStore > 0) { m_mutex.lock(); CCLOG("%d",m_nStore); --m_nStore; m_mutex.unlock(); }
} void HelloWorld::runStartMyThread2() {
while (m_nStore > 0) {
m_mutex.lock(); CCLOG("%d",m_nStore); --m_nStore;
m_mutex.unlock(); } } // on "init" you need to initialize your instance bool HelloWorld::init() { ////////////////////////////// // 1. super init first if ( !Layer::init() ) { return false; }
std::thread t(&HelloWorld::runStartMyThread,this); //t.join(); 该函数表示等待执行完线程在执行主线程 t.detach();
std::thread t2(&HelloWorld::runStartMyThread2,0)"> //t.join(); t2.detach(); } 结果如下： cocos2d: 50 cocos2d: 49 cocos2d: 48 cocos2d: 47 cocos2d: 46 cocos2d: 45 cocos2d: 44 cocos2d: 43 cocos2d: 42 cocos2d: 41 cocos2d: 40 cocos2d: 39 cocos2d: 38 cocos2d: 37 cocos2d: 36 cocos2d: 35 cocos2d: 34 cocos2d: 33 cocos2d: 32 cocos2d: 31 cocos2d: 30 cocos2d: 29 cocos2d: 28 cocos2d: 27 cocos2d: 26 cocos2d: 25 cocos2d: 24 cocos2d: 23 cocos2d: 22 cocos2d: 21 cocos2d: 20 cocos2d: 19 cocos2d: 18 cocos2d: 17 cocos2d: 16 cocos2d: 15 cocos2d: 14 cocos2d: 13 cocos2d: 12 cocos2d: 11 cocos2d: 10 cocos2d: 9 cocos2d: 8 cocos2d: 7 cocos2d: 6 cocos2d: 5 cocos2d: 4 cocos2d: 3 cocos2d: 2 cocos2d: 1 cocos2d: run in main thread （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
