搭建步骤
第一步：下载Cocos2d第二步：解压并安装Cocos2d
第三步：设置Cocos2d
第四步：使用cocos命令创建游戏项目
下载Cocos2d
下载地址：http://www.cocos2d-x.org/download 本例下载的版本是cocos2d-x-4.0
注意：不同版本的cocos2d的配置过程可能不一样，可以参考解压文档里的README.md文件。
解压并安装Cocos2d
- 下载的文档是zip格式，可以轻松地将其解压到某个目录下
- 安装Cocos2d
// 赋予install-deps-linux.sh执行权限
~/Desktop/coco2dx/cocos2d-x-4.0$ sudo chmod 754 install-deps-linux.sh
// 安装Cocos2d
~/Desktop/coco2dx/cocos2d-x-4.0$ ./install-deps-linux.sh
配置Cocos2d
~/Desktop/coco2dx/cocos2d-x-4.0$ python setup.py
完整的配置过程：
~/Desktop/coco2dx/cocos2d-x-4.0$ python setup.py
Setting up cocos2d-x...
->Check environment variable COCOS_CONSOLE_ROOT
->Search for environment variable COCOS_CONSOLE_ROOT...
->COCOS_CONSOLE_ROOT not found
-> Add COCOS_CONSOLE_ROOT environment variable...
->Added COCOS_CONSOLE_ROOT=/home/kyun/Desktop/coco2dx/cocos2d-x-4.0/tools/cocos2d-console/bin
->Check environment variable COCOS_X_ROOT
->Search for environment variable COCOS_X_ROOT...
->COCOS_X_ROOT not found
-> Add COCOS_X_ROOT environment variable...
->Added COCOS_X_ROOT=/home/kyun/Desktop/coco2dx
->Check environment variable COCOS_TEMPLATES_ROOT
->Search for environment variable COCOS_TEMPLATES_ROOT...
->COCOS_TEMPLATES_ROOT not found
-> Add COCOS_TEMPLATES_ROOT environment variable...
->Added COCOS_TEMPLATES_ROOT=/home/kyun/Desktop/coco2dx/cocos2d-x-4.0/templates
->Configuration for Android platform only, you can also skip and manually edit "/home/kyun/.bashrc"
->Check environment variable NDK_ROOT
->Search for environment variable NDK_ROOT...
->NDK_ROOT not found
->Search for command ndk-build in system...
->Command ndk-build not found
->Please enter the path of NDK_ROOT (or press Enter to skip):/home/kyun/Android/Sdk/ndk/16.1.4479499
-> Add NDK_ROOT environment variable...
->Added NDK_ROOT=/home/kyun/Android/Sdk/ndk/16.1.4479499
->Check environment variable ANDROID_SDK_ROOT
->Search for environment variable ANDROID_SDK_ROOT...
->ANDROID_SDK_ROOT is found : /home/kyun/Android/Sdk
A backup file "/home/kyun/.bashrc.backup" is created for "/home/kyun/.bashrc".
Please execute command: "source /home/kyun/.bashrc"
在配置的过程中，它会要求设置NDK的路径：
>Please enter the path of NDK_ROOT (or press Enter to skip):/home/kyun/Android/Sdk/ndk/16.1.4479499
本例输入/home/kyun/Android/Sdk/ndk/16.1.4479499，再按回车即可。
同时还会要求设置ANDROID_SDK_ROOT环境变量，值是android sdk的路径。这些配置都是写在/home/kyun/.bashrc这个脚本里。如果设置后，.bashrc脚本的最后就会有这些配置信息：
# Add environment variable COCOS_CONSOLE_ROOT for cocos2d-x
export COCOS_CONSOLE_ROOT="/home/kyun/Desktop/coco2dx/cocos2d-x-4.0/tools/cocos2d-console/bin"
export PATH=$COCOS_CONSOLE_ROOT:$PATH
# Add environment variable COCOS_X_ROOT for cocos2d-x
export COCOS_X_ROOT="/home/kyun/Desktop/coco2dx"
export PATH=$COCOS_X_ROOT:$PATH
# Add environment variable COCOS_TEMPLATES_ROOT for cocos2d-x
export COCOS_TEMPLATES_ROOT="/home/kyun/Desktop/coco2dx/cocos2d-x-4.0/templates"
export PATH=$COCOS_TEMPLATES_ROOT:$PATH
# Add environment variable ANDROID_SDK_ROOT for cocos2d-x
export ANDROID_SDK_ROOT=/home/kyun/Android/Sdk
export PATH=$ANDROID_SDK_ROOT:$PATH
# Add environment variable NDK_ROOT for cocos2d-x
export NDK_ROOT="/home/kyun/Android/Sdk/ndk/16.1.4479499"
export PATH=$NDK_ROOT:$PATH
使用source命令让脚本生效：
~/Desktop/coco2dx/cocos2d-x-4.0$ source /home/kyun/.bashrc
使用cocos命令创建游戏项目
$ cocos new MyGame -p com.your_company.mygame -l cpp -d NEW_PROJECTS_DIR
如：
~/Desktop/Games$ cocos new MyGame -l cpp -p com.wong.game -d Games
结果：
~/Desktop/Games$ ls
MyGame
~/Desktop/Games$ cd MyGame
~/Desktop/Games/MyGame$ ls
Classes cocos2d proj.ios_mac proj.win32
CMakeLists.txt proj.android proj.linux Resources
运行游戏
运行cmake，生成makefile文件
~/Desktop/Games/Games/FirstGame$ mkdir -p build/linux-build
~/Desktop/Games/Games/FirstGame$ cd build/linux-build
~/Desktop/Games/Games/FirstGame$ cmake ../..
运行make命令编译
~/Desktop/Games/Games/FirstGame/build/linux-build$ make -j 4
运行
~/Desktop/Games/Games/FirstGame/build/linux-build$ cd bin
~/Desktop/Games/Games/FirstGame/build/linux-build/bin$ ./FirstGame/FirstGame
上面是在ubuntu18.04编译运行的。在不同平台上也是这样子去编译的。
使用Android Studio开发
使用Android Studio导入~/Desktop/Games/Games/FirstGame/proj.android，即可直接使用Android Studio开发。导入步骤：New ->Import Project…
