大家好，我是佛系工程师☆恬静的小魔龙☆，不定时更新Unity开发技巧，觉得有用记得一键三连哦。

一、前言

在开发中，会遇到要使用监控键盘输入的KeyCode值来执行代码的情况。

比如说：

csharp 复制代码 
using System;
using UnityEditor;
using UnityEngine;

public class Test01 : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.W))
        {
			 Debug.Log("点击了键盘W");
        }
    }
}

但是，如果是一些不常用的键位，比如说{}[]，这些KeyCode值就比较难查看了，因为API是这样的：

根本不知道这英文还是数字代表了啥，于是就诞生了，在Unity做一个键盘，然后在键盘的键位下标注每个键位的KeyCode值，方便开发。

先看下效果图：

小明：键位没有对齐，逼死强迫症啊喂！
张三：不重要！不重要！

二、正文

2-1、构建键盘键值表

让我们新建一个脚本，命名为VirtualKeyboardEditor.cs名字无所谓，主要是要继承与EditorWindow类，并且把脚本放到Editor文件夹内。

编辑代码：

csharp 复制代码 
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

public class VirtualKeyboardEditor : EditorWindow
{
    [MenuItem("工具/键盘映射值")]
    static void OpenWindow()
    {
        GetWindow<VirtualKeyboardEditor>().Show();
    }
    //用于绘制窗口内容
    private void OnGUI()
    {
    }
}

然后，我们需要写一个自定义类，用来保存键盘值名和KeyCode值，以及长宽。

csharp 复制代码 
// 键盘映射value值
public class VirKeyValue
{
    public float height;
    public float width;
    public string name;
    public string key;
    public VirKeyValue(string name, string key, float width, float height)
    {
        this.name = name;
        this.width = width;
        this.height = height;
        this.key = key;
    }
}

接着构建键值库：

csharp 复制代码 
static Dictionary<int, List<VirKeyValue>> dicVirKeys;
    const int width1 = 50;
    const int width2 = 80;
    const int width100 = 100;
    const int width120 = 120;
    const int width140 = 138;
    const int width3 = 300;
    const int height1 = 30;

    private void DataInit()
    {
        if (dicVirKeys == null)
        {
            dicVirKeys = new Dictionary<int, List<VirKeyValue>>();
            List<VirKeyValue> tempVirKeys = new List<VirKeyValue>
            {
                new VirKeyValue("Esc","Esc", width1, height1),
                new VirKeyValue("F1","F1", width1, height1),
                new VirKeyValue("F2","F2", width1, height1),
                new VirKeyValue("F3","F3", width1, height1),
                new VirKeyValue("F4","F4", width1, height1),
                new VirKeyValue("F5","F5", width1, height1),
                new VirKeyValue("F6","F6", width1, height1),
                new VirKeyValue("F7","F7", width1, height1),
                new VirKeyValue("F8","F8", width1, height1),
                new VirKeyValue("F9","F9", width1, height1),
                new VirKeyValue("F10","F10", width1, height1),
                new VirKeyValue("F11","F11", width1, height1),
                new VirKeyValue("F12","F12", width1, height1),
                new VirKeyValue("Print\nScreen","Print", width1, height1),
                new VirKeyValue("Scroll\nLock", "ScrollLockScroll",width1, height1),
                new VirKeyValue("Pause","Pause", width1, height1)
            };
            dicVirKeys.Add(0, tempVirKeys);

            tempVirKeys = new List<VirKeyValue>
            {
                new VirKeyValue("~\n`","BackQuote", width1, height1),
                new VirKeyValue("!\n1","Alpha1", width1, height1),
                new VirKeyValue("@\n2","Alpha2", width1, height1),
                new VirKeyValue("#\n3","Alpha3", width1, height1),
                new VirKeyValue("$\n4","Alpha4", width1, height1),
                new VirKeyValue("%\n5","Alpha5", width1, height1),

                new VirKeyValue("&\n7","Alpha7", width1, height1),
                new VirKeyValue("*\n8","Alpha8", width1, height1),
                new VirKeyValue("(\n9","Alpha9", width1, height1),
