CustomEditor 自定义组件编辑器

• 1:首先生成一个继承Monobehiver的脚本名字叫做Character,生成一个类型为int的属性叫做Attack,再生成一个CharacterInspector脚本放在Editor文件夹中

    using UnityEngine;
    using UnityEditor;
  
  

[CanEditMultipleObjects]
[CustomEditor(typeof(Character))]
public class CharacterInspector : Editor
{
    SerializedProperty AttackProperty;

    void OnEnable()
    {
        AttackProperty = serializedObject.FindProperty("Attack");
    }

    public override void OnInspectorGUI()
    {
        serializedObject.Update();

        EditorGUILayout.IntSlider(AttackProperty, 0, 100);

        serializedObject.ApplyModifiedProperties();
    }
}

* 2:PropertyDrawer 的使用

[System.Serializable]
public class PropertyDrawerExample
{
    public int minHp;
    public int maxHp;
}

public class PropertyDrawer1 : MonoBehaviour
{
    public PropertyDrawerExample example;
}

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

[CustomPropertyDrawer(typeof(Example))]
public class PropertyDrawerEditor : PropertyDrawer
{
    public override void OnGUI(Rect position,
                        SerializedProperty property, GUIContent label)
    {
        using (new EditorGUI.PropertyScope(position, label, property))
        {

            var minHpProperty = property.FindPropertyRelative("minHp");
            var maxHpProperty = property.FindPropertyRelative("maxHp");

            //表示位置
            var minMaxSliderRect = new Rect(position)
            {
                height = position.height * 0.5f
            };

            var labelRect = new Rect(minMaxSliderRect)
            {
                x = minMaxSliderRect.x + EditorGUIUtility.labelWidth,
                y = minMaxSliderRect.y + minMaxSliderRect.height
            };

            float minHp = minHpProperty.intValue;
            float maxHp = maxHpProperty.intValue;

            EditorGUI.BeginChangeCheck();

#pragma warning disable CS0618 // 类型或成员已过时
            EditorGUI.MinMaxSlider(label,
                        minMaxSliderRect, ref minHp, ref maxHp, 0, 100);
#pragma warning restore CS0618 // 类型或成员已过时

            EditorGUI.LabelField(labelRect, minHp.ToString(), maxHp.ToString());

            if (EditorGUI.EndChangeCheck())
            {
                minHpProperty.intValue = Mathf.FloorToInt(minHp);
                maxHpProperty.intValue = Mathf.FloorToInt(maxHp);
            }
        }
    }

    public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
    {
        return base.GetPropertyHeight(property, label) * 2;
    }
}

* 3:HasPreviewGUI可以展示预览状态

public override bool HasPreviewGUI ()
{
return true;
}
public override GUIContent GetPreviewTitle ()
{
return new GUIContent (“title”);
}
public override void OnPreviewSettings ()
{
GUIStyle preLabel = new GUIStyle (“preLabel”);
GUIStyle preButton = new GUIStyle (“preButton”);

GUILayout.Label ("t", preLabel);
GUILayout.Button ("t2", preButton);

}
public override void OnPreviewGUI (Rect r, GUIStyle background)
{
GUI.Box (r, “Preview”);
}

* 4:PreviewRenderUtility在预览状态下,设置一个摄像机,照出当前的物体.待续
* 5:完整的表示并使用PropertyDrawer,他是将一个数据类,完整的显示在一个脚本的Inspector面板上面

public enum Sex
{
    famale,//女同志
    male//男同志
}

[System.Serializable]
public class Persion
{
    public string name;

    public Sex sex;

    public int age;

    public string description;
}

using UnityEngine;

public class ShowPersionInfo : MonoBehaviour
{
    public Persion persion;
}

using System;
using UnityEngine.UI;
using UnityEngine;
using UnityEditor;

[CustomPropertyDrawer(typeof(Persion))] //自定义属性控制
public class PersionPropertiesDrawer : PropertyDrawer
{
Rect top, middleLeft, middleRight, bottom;//绘制指定的区域
SerializedProperty persionName, sex, age, description;//绘制对应的序列化属性
public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
//base.OnGUI(position, property, label);
//Debug.Log(“label:” + label.text);
//Debug.Log(position);
//Debug.Log(“OnGUI:” + property.name);

    //这个地方是将property转换成下一个property,也就是从persion这个属性转成Persion类中的name,sex,age,description属性了
    //while (property.NextVisible(true))
    //{
    //    //Debug.Log("OnGUI:" + property.name);
    //}
    top = new Rect(position.x, position.y, position.width, position.height / 4);
    middleLeft = new Rect(position.x, position.y + position.height / 4, position.width/2, position.height / 4/2);
    middleRight = new Rect(position.x + position.width/2, position.y + position.height / 4, position.width/2, position.height / 4);
    bottom = new Rect(position.x, position.y + position.height / 2, position.width, position.height / 2);

    //获取对应的序列化属性
    //property这个属性对应的是 ShowPersionInfo 脚本中的Persion对象的persion属性,
    //里面有几个Persion对象的persion属性,就调用这个方法绘制多少次
    persionName = property.FindPropertyRelative("name");//通过属性的名字获取对应的序列化对象SerializedProperty
    sex = property.FindPropertyRelative("sex");
    age = property.FindPropertyRelative("age");
    description = property.FindPropertyRelative("description");

    //绘制属性
    //EditorGUI.PropertyField第一个参数绘制该属性在Inspector在面板的位置.
    EditorGUI.PropertyField(top, persionName);
    EditorGUI.PropertyField(middleLeft, sex);
    EditorGUI.PropertyField(middleRight, age);
    description.stringValue = EditorGUI.TextArea(bottom, description.stringValue);
}

public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
{
    while (property.NextVisible(true))
    {
        //Debug.Log("GetPropertyHeight:" + property.name);
    }
    return base.GetPropertyHeight(property, label) * 4;
}

/**
 * 1.OnGUI 和 GetPropertyHeight 里的 property 参数是同一个参数。该参数里存放的是 Persion 里的属性信息。
 * 2.OnGUI 和 GetPropertyHeight 里的 Label 参数也是同一个参数，该参数里存放的是 Persion 类的类名。
 * 3.position参数指的是需要在Inspector面板中绘制的区域信息,即当前脚本挂在在到GameObject上面的Inspector上的区域
 * 4.在Inspector面板中的一行高度为 16
