PropertyDrawer 自定义属性绘图

public class PlayerAttributeExample : MonoBehaviour
{
    //无滑块的属性
    public int VIPLevel = 0;

    //特性限定,有滑块
    [Range(0, 10)]
    public int SliderVIPLevel = 0;
}

 

Range特性的方法实现:

using UnityEngine;
using System.Collections;

//特性的定义要继承自PropertyAttribute
public class MyRangeAttribute : PropertyAttribute
{
    public float Min;//最小值
    public float Max;//最大值

    public MyRangeAttribute(float min, float max)
    {
        this.Min = min;
        this.Max = max;
    }
}
using UnityEngine;
using System.Collections;
using UnityEditor;

//继承PropertyDrawer, 必须放入Editor文件夹下
[CustomPropertyDrawer(typeof(MyRangeAttribute))]
public class MyRangeAttributeDrawer : PropertyDrawer
{
    //重载OnGUI方法
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        MyRangeAttribute myRange = attribute as MyRangeAttribute;

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

        }
    }

}

 

2.绘制多选

    public enum SomeFood
    {
        汉堡 = 0,
        鸡肉卷 = 1,
        薯条 = 3,
    }
    //只能单选
    public SomeFood MyLoveFood;

    //多选特性
    [EnumListAttribute]
    public SomeFood MyLoveFoodList;
using UnityEngine;
using System.Collections;

public class EnumListAttribute : PropertyAttribute
{

}
using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomPropertyDrawer(typeof(EnumListAttribute))]
public class EnumListAttributeDrawer : PropertyDrawer
{
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
        property.intValue = EditorGUI.MaskField(position, label, property.intValue, property.enumNames);
    }
}
