遊戲開發新手教Cocos2D-X怎學習，只有C++開發經驗

恭喜你，cocos2d-x就是用c++寫的，理論知道可以參考相關的cocos2d。網上有很多cocos2d的社區，多看看吧！多逛逛論壇。要理解情境，層，精靈，Action等相關概念。
 
對於Cocos2D-X這遊戲引擎的幾個簡單問題，

1、理論上cocos2d-x官方表明支援的平台毫無疑問你都是可以進行移植的，這正是它跨平台的優勢所在。
2、cocos2d-x的跨平台特性體現在它是使用C++作為程式設計語言進行開發，並且提供了各個平台編譯啟動並執行解決方案。你無論在什麼開發環境下，都可以進行開發，你的編寫過程無非是用C++寫代碼邏輯。當然你最終想在各個平台部署，還要進行一些特殊處理。比如ios的你需要配置mac下的開發環境，安裝xcode，安裝認證等等，android你需要安裝NDK、ADT等等，我就不贅述了。具體過程網上搜教程一步一步來，大家都是這麼摸索過來的。先逮著一個你熟悉的開發環境和目標平台做，比如先用VS開發，編譯到安卓或者xcode開發運行到ios。
