本文介绍了如何在Unity中使用自定义编辑器功能，包括菜单项、组件需求、上下文菜单及自定义属性等，还提供了操作文件和批量修改材质导入设置的具体实现。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

一、MenuItem

点击My Window时调用Init()

二、RequireComponent

添加脚本A时自动添加刚体组件

三、AddComponentMenu

当按下脚本A时，为当前选择的GameObject添加脚本A

四、ContextMenu

按下Test时，执行Test()

五、自定义Attribute属性

using UnityEngine;
using System.Collections;

public class TestAttribute : MonoBehaviour {

    [Range(0, 10)]
    public int a;

    [MyRange(-5f, 5f)]
    public float b;

    public enum Force {蜀国,吴国,魏国};

    [MyEnum]
    public Force force;//多选
}

using UnityEngine;
using System.Collections;

public class MyRange : PropertyAttribute {

    public float min;
    public float max;

    public MyRange(float min, float max)
    {
        this.min = min;
        this.max = max;
    }
}

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomPropertyDrawer(typeof(MyRange))]
public class MyRangeDrawer : PropertyDrawer {

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        MyRange myRange = attribute as MyRange;

        if (property.propertyType == SerializedPropertyType.Float)
            EditorGUI.Slider(position, property, myRange.min, myRange.max, label);
        else if (property.propertyType == SerializedPropertyType.Integer)
            EditorGUI.IntSlider(position, property, (int)myRange.min, (int)myRange.max, label);
    }
}

using UnityEngine;
using System.Collections;

public class MyEnum : PropertyAttribute {

	
}

using UnityEngine;

[CustomPropertyDrawer(typeof(MyEnum))]
public class MyEnumDrawer : PropertyDrawer {

    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        property.intValue = EditorGUI.MaskField(position,label,property.intValue,property.enumNames);
    }
}
