Unity 在Inspector面板上實現多選枚舉

//EnumFlags.cs
using UnityEngine;
///<summary>
///定義多選屬性
///</summary>
public class EnumFlags : PropertyAttribute{}




//EnumFlagsDrawer.cs

using UnityEngine;
using UnityEditor;

///<summary>
///繪制多選屬性
///</summary>
[CustomPropertyDrawer(typeof(EnumFlags))]
public class EnumFlagsDrawer : PropertyDrawer
{
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        property.intValue = EditorGUI.MaskField(position, label, property.intValue, property.enumNames);
    }
}


//在需要多選的枚舉變量的聲明上加上EnumFlags屬性標簽,如:
[Hear("這里是標題")]
[EnumFlags] //這里是EnumFlags屬性標簽
public EnumType enumType; 

效果如圖
