Unity3D - modification of the Inspector panel of the custom class

Unity3D——自定义类的InspectorModification of the panel

1. 预期目标： for custom classesInspector面板进行修改,达到如下效果
   
2. 步骤
   （1）Create your own script（例如Help.cs）,置于Assets / Scripts目录（非必须）下
   （2）Create a script corresponding to it（HelpInspector.cs）, 置于 Assets / Editor 目录（没有可自行创建）下
   （3）在SudentInspector.cs中
   

• 引用UnityEditor命名空间
• 添加特性[CutomEditor(typeof(Help))]
• 继承Editor类
• 重写OnInspectorGUI类

3. 注意：这里重写OnInspectorGUI方法时,The compiler comes with calls in the parent classOnInspectorGUI,Here if you don't want toHelpUnwanted in the classpublic变量出现在Inspector面板上,就将base.OnInspectorGUI()注释掉

4. 代码

// SudentInspector.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

using UnityEditor;

[CustomEditor(typeof(Help))]
public class HelpInspector : Editor
{
    
    public override void OnInspectorGUI()
    {
    
        Help myHelp = (Help)target;        // target就是Help Inspector的实例

        GUILayout.BeginVertical();
        GUILayout.Label("Help Here");
        GUILayout.Label("Version: 1.0.0");        
        GUILayout.EndVertical();

        GUILayout.BeginHorizontal();
        GUILayout.Label("Test Input", GUILayout.Width(60));
        myHelp.helpId = EditorGUILayout.IntField( myHelp.helpId,GUILayout.Width(150));
        GUILayout.EndHorizontal();

        GUILayout.BeginVertical();
        myHelp.helpName = EditorGUILayout.TextField(myHelp.helpName, GUILayout.Width(150));
        GUILayout.EndVertical();
    }
}





// Help.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Help : MonoBehaviour
{
    
    public bool helpHere;
    public int helpId;
    public string helpName;
}

功能

5. 注意

• 这里的target就是指Help创建出来的Help实例（面板）,如果想要控制Help中的变量,No more new instances can be created,Because we are going to control the instance that has been created on the panel,也就是target
