Cocos2d-x 3.1 HelloWorld解析
创建一个Cocos2dx_C++项目 需要先安装 Python
cocos2d-x-3.10\tools\cocos2d-console\bin下 用python 打开cocos.py
创建一个项目
python cocos.py new hellogame -p com.hanhan.hellogame -l cpp -d e:\cocos2dxpros\hellogame
下面是实例:
/**************************************************************

下面是helloworld解析
