Cocos2d-x 3.2 Lua樣本FontTest（字型測試）

  本篇部落格介紹Cocos2d-x 3.2中Lua測試專案中的FontTest例子，主要使用了字型檔來建立我們想要的字型樣式：

第一個參數為文本，第二參數為ttf字型檔，第三個參數為字型大小，第四個參數為塊大小，第五個參數為文本橫向對齊，第六個慘為文本縱向對齊。

例子：

範例程式碼：（註：單獨檔案不可運行，具體可參考lua-tests)

VS2010裡面建立cocos2D-x項目時，選擇Select Lua support: Support Lua（打鉤），產生後報錯，

一些庫檔案沒正確載入，找到相應的庫檔案粘貼到相應位置就好了。別忘記確認下該檔案是否有許可權。
 
cocos2d-x怎與Lua想結合使用 具體點

cocos2d-x帶有lua引擎了。看看這個。雖然是英語，但是很容易懂。
Cocos2d-x NEW Lua Engine README
Main features
Support autorelease CCObject object.
Call Lua function from C++ (local, global, closure), avoid memory leaks.
Add CCNode:setPosition(x, y), CCNode::getPosition() huge performance boost.
Remove needless class and functions from tolua++ .pkg files, improved performance.
CCMenuItem events handler.
CCNode onEnter/onExit events handler.
CCLayer touch & multi-touches events handler.
看看這2個串連。
