public class DataBaseTest : MonoBehaviour {

string strName = "";

GUI.Label(newRect(300,320,150,70),strName);

GUI.Label(newRect(300,430,150,70),strSex);

}

}

2.導入dll

同先前的帖子 ,將MySql.data.dllImport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

staticstringhost = "192.168.1.100";

staticstringid = "mysql";

staticstringpwd = "123456";

staticstringdatabase = "test";

privatestringstrCommand = "Select * from unity3d_test ORDER BYid;";

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primarykey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"ClickMe"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 , 歡迎各位高手能夠多多批評指教
