复制代码 2.導入dll
同先前的帖子 , 將MySql.data.dll Import至Assets底下 , 然後再到Unity\Editor\Data\Frameworks\Mono.framework 中
將System.Data.dll 也一起Import至Assets內 , 當然 , 如果想顯示中文的話 , 請參考中文視頻教學 , 建立一個GUISkin與字型
3.建立數據庫內容
主要是因為代碼中的這段內容- static string host = "192.168.1.100";
- static string id = "mysql";
- static string pwd = "123456";
- static string database = "test";
- private string strCommand = "Select * from unity3d_test ORDER BY id;";
复制代码 其中host ,id , pwd 請自行設定 , 簡單的說就是連進你的MySQL啦~
然後建立一個名為test的Database , 在這個test下建立一張table , 取名為 unity3d_test ,
接下來就為這張unity3d_test建立3個欄位 : ID , Name , Sex (記得將ID設定為primary key 且默認值為1)
再來自行填入5筆資料(5筆資料的原因是腳本那邊是設定成5筆資料一個循環 , 使用者可以自行更改腳本試試)
4.建立GameObject
建立完GameObject後將上面兩個腳本掛上去 , 如果有建立GUISkin , 記得指定GUISkin
5.執行
執行後先按Test按鈕來連接數據庫 , 然後再按"Click Me"來顯示數據庫內的內容
6.總結
以上部份是有關連線至數據庫後 , 再將資料用DataSet的方式獲得出來再加以顯示至介面上 .
