unity 登入与注册界面（连接本地MySQL）实现
unity 登录与注册界面（连接本地MySQL）实现
首先unity连接到本地MySQL
1.先去MySQL下载好插件如下
dada.ll.
- 下完后将下面的压缩包解压找到如下组件放到unity新建的文件夹Plugins
3.
- 做完后到MySQL创建一个数据库和表格如下
接下来搭建场景如下我用image做的注册和登入界面
记得加一个文本作为提示文本
写入代码挂在canvas上记得最后将两个组件托进去先给主代码

public class Account : MonoBehaviour

public GameObject registerbg;
private InputField regisUsername;
private InputField repassword;
private Text hinttext1;
//登入界面
public GameObject singbg;
private InputField UsernameInput;
private InputField Password;
private Text hinttext;//提示文本
private string Password1;
private string username;
private void Awake()
{
//获取登入界面输入组件
UsernameInput = singbg.transform.Find("loginbg/ACCount/UsernameInput").GetComponent<InputField>();
Password = singbg.transform.Find("loginbg/Password/PasswordInput").GetComponent<InputField>();
//提示文本
hinttext = singbg.transform.Find("hint").GetComponent<Text>();
hinttext1= registerbg.transform.Find("hint1").GetComponent<Text>();
//获取注册界面输入组件
regisUsername = registerbg.transform.Find("loginbg/ACCount/UsernameInput").GetComponent<InputField>();
repassword= registerbg.transform.Find("loginbg/Password/PasswordInput").GetComponent<InputField>();
}

SceneManager.LoadScene("Game");//跳转至主游戏界面自己新建一个游戏场景
}

//每一次返回的清空
private void emptytex()

//组件直接的查询

foreach (Button button1 in signButtonList)
{
button1.onClick.AddListener(() =>

}
//注册界面实现

}
}
//模式管理场景的按钮点击事件
private void LoginWindowButtonClick(Button sender)
{
switch (sender.name)
{
//注册界面注册按钮
case "Rebutton":
{
Debug.Log("ok");
username = regisUsername.text.Trim();
Password1 = repassword.text.Trim();
if (username == ""&& Password1=="")
{
hinttext1.text="用户的账号密码不能为空";
}
else
{
regions(new string[] {
username, Password1});//调用数据库的方法
}
} break;
case "Back1":
{
singbg.SetActive(true);
registerbg.SetActive(false);
emptytex();
}
break;
//登入界面登入按钮
case "siginbutton":
{

}break;
case "logbutten":
{
Debug.Log("成功");
username = UsernameInput.text.Trim();
Password1 = Password.text.Trim();
if (UsernameInput.text.Trim() == ""&&Password.text.Trim()=="")
{
hinttext.text="用户的账号密码不能为空，请注册";
}
else
{
Login(new string[] {
username, Password1 });//调用数据库方法
}
}
break;
default:
break;
}
}
}
单独提出来登入注册方法
不想写了看看能不能看懂不能留言下

{
}

//定义数据库连接对象，传递对象
MySqlConnection conn = new MySqlConnection(connectStr); //并没有建立数据库连接
//打开数据库

//数据库连接成功

{

string Password1 = reader.GetString("password");
myDic.Add(username,Password1);
}
if (myDic.ContainsKey(str[0]))
{
hinttext1.text = "账号存在！请重新注册";
}
else
{
reader.Close();
