【cocos2dx 3.2】2048

打包好的APK：http://pan.baidu.com/share/link?shareid=847502897&uk=185595768

游戏分析请看【Android重制2048】

打包方法：

（1）将工程导入eclipse中(记得将xml文档中调成竖屏模式)

（2）将VS工程中的D:\hello\Card\cocos2d\cocos\2d\platform\android\java\src里的org文件夹拖进eclipse的src

（3）修改eclipse工程中jni文件下的Android.mk文件

参考：http://blog.csdn.net/gf771115/article/details/34414449

（4）打开CMD，运行到VS工程中的proj.android下，执行Build_native.py

（5）成功后重新导入工程到eclipse中

（6）最后导出apk

效果：

AppDelegate.cpp(修改分辨率和屏幕大小)

#include "AppDelegate.h"#include "HelloWorldScene.h"USING_NS_CC;AppDelegate::AppDelegate() {}AppDelegate::~AppDelegate() {}bool AppDelegate::applicationDidFinishLaunching() {    // initialize director    auto director = Director::getInstance();    auto glview = director->getOpenGLView();    if(!glview) {//修改屏幕大小        glview = GLView::createWithRect("My2048",Rect(0,0,286,512),1.0f);        director->setOpenGLView(glview);    }//分辨率适应glview->setDesignResolutionSize(268,512,ResolutionPolicy::EXACT_FIT);       director->setDisplayStats(true);    director->setAnimationInterval(1.0 / 60);    auto scene = HelloWorld::createScene();    director->runWithScene(scene);    return true;}void AppDelegate::applicationDidEnterBackground() {    Director::getInstance()->stopAnimation();}void AppDelegate::applicationWillEnterForeground() {    Director::getInstance()->startAnimation();}
