如何在Unity中创建登录窗口

Question

I am new at C# and can't get my username and password program to work.

I need to get the inputs from the user and check it against the account details which I've stored in a dictionary.

Answer 1

Note that Console.WriteLine does not work in Unity. You have to use Debug.Log .

I am new at C# and can't get my username and password program to work.

1 .Create two InputFileds . One for username and one for password .

You can do that by going to GameObject --> UI --> Input Field

2 .Create the Submit Button .

You can do that by going to GameObject --> UI --> Button

3 .Subscribe to the submit Button onClick event so that when it it clicked, the adminDetails() function will be called.

That's it. You can get the input with InputField.text .

using System;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class AdminLogin : MonoBehaviour
{

    public InputField userNameField;
    public InputField passwordField;
    public Button loginButton;

    void Start()
    {
        //Subscribe to onClick event
        loginButton.onClick.AddListener(adminDetails);
    }

    Dictionary<int, string> staffDetails = new Dictionary<int, string>
    {
        {101,"femi1998" },
        {102,"kwaks1999" },
        {103,"eman1999" }
    };


    public void adminDetails()
    {
        //Get Username from Input then convert it to int
        int userName = Convert.ToInt32(userNameField.text);
        //Get Password from Input 
        string password = passwordField.text;

        string foundPassword;
        if (staffDetails.TryGetValue(userName, out foundPassword) && (foundPassword == password))
        {
            Debug.Log("User authenticated");
        }
        else
        {
            Debug.Log("Invalid password");
        }
    }
}

Don't forget to drag both created InputFields and the Button to the userNameField , passwordField and loginButton slots in the Editor.
