物件導向 初識物件導向

面向過程思想 步驟清晰簡單，第一步做什麼，第二步做什麼.面向過程適合處理一些較為簡單的問題 物件導向思想 物以類聚，分類的思維模式，思考問題首先會解決問題需要分哪些類，然後對這些類進行單獨思考，最後才是對某個分類下的細節進行面向過程的思索 物件導向適合處理複雜的問題，適合處理需要多人協作的問題 對於...

Xlua 學習記錄（一）Xlua 案例學習

有空看了下lua，研究下xlua。筆記如下 void start 1 dostring引數為string，可輸入任意合法的lua 本示例在lua裡呼叫c 的unityengine.debug.log列印了個日誌。2 乙個luaenv例項對應lua虛擬機器，出於開銷的考慮，建議全域性唯一。考慮全域性唯...
