Unity自定义输入方式（通过可视化面板进行输入）

去年某个时间段做VR功能预研，利用Pico一体机做开发，当时通过Unity内置Inputfield组件实现外部输入，该组件貌似是调用系统内置输入方式，Pico一体机那个时候的输入方式简则是蛋疼得很，因为一调用该输入法就是双目模式，这就算了，更难受的是输入法贴到眼睛上了，根本不好使，偶尔还有穿透。当时就有了想法自定义一套输入方式，奈何一直没时间，最近遇到一个项目必须要用到自定义的，所以就简单的搞了一套将就用着。上代码先：
1：输入面板代码

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text.RegularExpressions;

using UnityEngine;
using UnityEngine.UI;

using static UnityEngine.UI.GridLayoutGroup;

[RequireComponent(typeof(GridLayoutGroup))]
public class PanelInput : MonoBehaviour
{
    public delegate void DlAction(string input);
    public static event DlAction e_InputAction;
    public List<string> zimuli = new List<string>();
    public Font toChange;
    // Start is called before the first frame update
    void Start()
    {
        GridLayoutGroup group= GetComponent<GridLayoutGroup>();
        group.padding = new RectOffset(50, 50, 50, 50);
        group.spacing = new Vector2(20,20); 
        group.constraint = Constraint.FixedRowCount;
        group.constraintCount = 4;
        //添加字母到列表中。
        for (char i = 'A'; i <= 'Z'; i++)
            zimuli.Add(i.ToString());
        for (int i = 0; i < zimuli.Count; i++)
        {
            //此处为预制，也可以直接new一个空物体在添加组件，这里因为觉得太丑添加了个背景，然后做了个预制，虽然还是很丑
            GameObject item = Instantiate(Resources.Load<GameObject>("letterItem"),transform);
            item.name = zimuli[i].ToString();
            item.GetComponentInChildren<Text>().text = zimuli[i]; 
            item.GetComponentInChildren<Text>().font = toChange;
            item.GetComponentInChildren<Text>().color = Color.black; 
            item.AddComponent<Button>().onClick.AddListener(() => { OnClickBtn(item.name); }) ; 
        } 
    }

    private void OnClickBtn(string name)
    {
        gameObject.SetActive(false);
        e_InputAction(name);
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

2：查询面板代码：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text.RegularExpressions;

using UnityEngine;
using UnityEngine.UI;

using static UnityEngine.UI.GridLayoutGroup;

[RequireComponent(typeof(GridLayoutGroup))]
public class PanelInput : MonoBehaviour
{
    public delegate void DlAction(string input);
    public static event DlAction e_InputAction;
    public List<string> zimuli = new List<string>();
    public Font toChange;
    // Start is called before the first frame update
    void Start()
    {
        GridLayoutGroup group= GetComponent<GridLayoutGroup>();
        group.padding = new RectOffset(50, 50, 50, 50);
        group.spacing = new Vector2(20,20); 
        group.constraint = Constraint.FixedRowCount;
        group.constraintCount = 4;
        //添加字母到列表中。
        for (char i = 'A'; i <= 'Z'; i++)
            zimuli.Add(i.ToString());
        for (int i = 0; i < zimuli.Count; i++)
        {
            //此处为预制，也可以直接new一个空物体在添加组件，这里因为觉得太丑添加了个背景，然后做了个预制，虽然还是很丑
            GameObject item = Instantiate(Resources.Load<GameObject>("letterItem"),transform);
            item.name = zimuli[i].ToString();
            item.GetComponentInChildren<Text>().text = zimuli[i]; 
            item.GetComponentInChildren<Text>().font = toChange;
            item.GetComponentInChildren<Text>().color = Color.black; 
            item.AddComponent<Button>().onClick.AddListener(() => { OnClickBtn(item.name); }) ; 
        } 
    }

    private void OnClickBtn(string name)
    {
        gameObject.SetActive(false);
        e_InputAction(name);
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}
[Serializable]
public class PersonData 
{
    /// <summary>
    /// 工号
    /// </summary>
    public int Id { get; set; }
    /// <summary>
    /// 姓名
    /// </summary>
    public string Name { get; set; }
    /// <summary>
    /// 年龄
    /// </summary>
    public int Age { get; set; }
    /// <summary>
    /// 职位
    /// </summary>
    public string Occupation { get; set; }
    /// <summary>
    /// 所在部门
    /// </summary>
    public string Department { get; set; }
    /// <summary>
    /// 个人荣誉
    /// </summary>
    public string Honor { get; set; }
    public PersonData(int id ,string name ,int age,string occ,string det,string honnor) 
    {
        Id = id;
        Name = name;
        Age = age;
        Occupation = occ;
        Department = det;
        Honor = honnor; 
    }
}

3：场景面板设置：然后对应的节点挂上上面的两个脚本；

4：最后效果，大致原理差不多，要更好点的就是完善下输入的资源以及美化面板！
