我正在为 Unity 创建一个帐户系统，这是我的脚本，在 TextField 和 PasswordFields 之前的第 132、134、136 行出现错误。我说不出它有什么问题。任何帮助将不胜感激。

using UnityEngine;
using System.Collections;

public class menuManager : MonoBehaviour {

    public string currentMenu;

    public string Username;
    public string Password;

    private string userTre = "holybuttwipe";
    private string passTre = "tre";

    private string userDerek = "Prouda You";
    private string passDerek = "derek";

    private string userBodey = "cherrypepsi72";
    private string passBodey = "bodey";

    private string userCody = "Bear On The Moon";
    private string passCody = "cody";

    private bool tre = false;
    private bool derek = false;
    private bool bodey = false;
    private bool cody = false;



    void Start() {
        currentMenu = "Main";
    }

    void Update() {

    }

    void OnGUI() {
        if(currentMenu == "Main")
            Menu_Main();
        if(currentMenu == "Login")
            Menu_Login();
        if(currentMenu == "Game")
            Menu_Game();
        if(currentMenu == "Create")
            Menu_Create();
        GUI.Label(new Rect(100, 100, 100, 100), Username);
    }

    public void NavigateTo(string nextmenu) {

我怀疑你的问题如下：

newUsername = GUI.TextField(new Rect(100, 10, 100, 30), newUsername);

在为函数分配任何值之前，您正在使用 newUsername 作为函数的参数。当然，它会在 AFTERWARD 之后有一个价值，但它不能走那么远。

当然，您要使用不同的变量执行此操作 3 次。

newUsername = GUI.TextField(new Rect(100, 10, 100, 30), newUsername);

newPassword = GUI.PasswordField(new Rect(100, 50, 100, 30), newPassword, '*');

conPassword = GUI.PasswordField(new Rect(100, 90, 100, 30), conPassword, '*');

在这里，您正在使用newUsername，newPassword并且conPassword没有对它们应用任何值。您需要为它们分配一个字符串值，并将before它们作为参数传递。

或者，您可以像这样声明它们：

string newUsername = "";
string newPassword = "";
string conPassword = "";
