在Inspector 中 设置添加回调函数 - Unity3d编辑器扩展

标签：unity3d   编辑器   回调函数   inspector   

在做一些开场动画或者其它指定事件触发 一类功能时，需要在编辑环境下设置添加回调函数。

一开始尝试直接使用delegate 来编写，测试发现没有效果，在谷歌搜索到Unity论坛有人提到 delegate 不能被序列化到Inspector 中使用，建议使用 UnityEvent 。

UnityEvent ，其实在UGUI中经常用到，只是平时不知道是它。

比如按钮的点击事件就是

直接从 UGUI Button 的源代码中搬运出来。

先提供一个带有 UnityEvent 的类

TimeEventPlugin.cs

using UnityEngine;
using System.Collections;
using UnityEngine.Serialization;
using System;
using UnityEngine.Events;

public class TimeEventPlugin : MonoBehaviour 
{
    [SerializeField]
	public float m_DelayTime;

	[SerializeField]
	public TimeEventTrigger m_TimeEventTrigger=new TimeEventTrigger();


    private float delayTime;


    void Start()
    {
        delayTime = m_DelayTime;

		Debug.Log("TimeEventTrigger ID="+m_TimeEventTrigger.ID);
    }

    void Update()
    {

        delayTime -= Time.deltaTime;
		if (delayTime <= 0)
        {
            delayTime = m_DelayTime;
			m_TimeEventTrigger.m_TimeEvent.Invoke();
        }
    }

}

[Serializable]
public class TimeEventTrigger
{
	public int ID;

	[Serializable]
	public class  TimeEvent:UnityEvent{}
	
	[SerializeField]
	public TimeEvent m_TimeEvent=new TimeEvent();
}

using UnityEngine;
using System.Collections;
using UnityEditor;

[CustomEditor(typeof(TimeEventPlugin))]
public class TimeEventPluginEditor : Editor
{
	SerializedProperty m_serializedTimeEventTrigger;

    SerializedProperty m_serializedTimeEvent;

	TimeEventTrigger m_TimeEventTrigger;

	void OnEnable()
	{
		m_serializedTimeEventTrigger = serializedObject.FindProperty("m_TimeEventTrigger");
	}

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

		TimeEventPlugin plug = target as TimeEventPlugin;
		plug.m_DelayTime=EditorGUILayout.FloatField("m_DelayTime", plug.m_DelayTime);

		EditorGUILayout.PropertyField(m_serializedTimeEventTrigger,true);

		serializedObject.ApplyModifiedProperties();
	}
}

using UnityEngine;
using System.Collections;


public class Test : MonoBehaviour {

    

	// Use this for initialization
	void Start () 
    {
	}

    public void TimeEnd()
    {
        Debug.Log("TimeEnd");
    }
	
	// Update is called once per frame
	void Update () {
	
	}
}
