How can I get an Event widget in my own inspectors?

The thing in the screenshot I've attached - how can I get it in my own scripts?

I think he actually means this new thing:

http://docs.unity3d.com/460/Documentation/ScriptReference/Events.UnityEvent.html

 

To be more specific, you need to define your event and draw the property of the event in an editor script.

Example MonoBehaviour:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEngine.Events;
4. using UnityEngine.EventSystems;
5. using System;
6. using System.Collections;
7.  
8. namespace UnityEngine.UI
9. {
10.     public class Example : MonoBehaviour {
11.    
12.         [Serializable]
13.         public class ExampleEvent : UnityEvent {}
14.    
15.         public ExampleEvent onEvent = new ExampleEvent();
16.     }
17. }

Example editor script:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEngine.UI;
4. using UnityEditor;
5.  
6. namespace UnityEditor.UI
7. {
8.     [CustomEditor(typeof(Example))]
9.     public class ExampleEditor : Editor {
10.    
11.         public override void OnInspectorGUI()
12.         {
13.             this.serializedObject.Update();
14.             EditorGUILayout.PropertyField(this.serializedObject.FindProperty("onEvent"), true);
15.             this.serializedObject.ApplyModifiedProperties();
16.         }
17.     }
18. }

 

The UnityEvent class was the magic word I was looking for, thanks

I just tried something, and it turns out, that's definitely overcomplicating it assuming you don't need to do anything super-complicated with them. You don't need an Editor script, nor do you really need to derive from UnityEvent.

This is basically all I needed to do:

Code (csharp):

1.  
2. public class SomeComponent : MonoBehaviour {
3. public UnityEvent OnPressButtonA;
4.  
5. void Update() {
6. if (Input.GetKeyDown("a") ) OnPressButtonA.Invoke();
7. }
8. }
9.  

This works and displays the event widget in the inspector as desired.

 

I guess the topic title mislead me, i thought you already have an editor script and was wondering how to draw the even property...

Anyways, im glad you found what you ware looking for.

 

BTW if u need extend UnityEvent inspector you could derive from UnityEventDrawer class which behave like custom propertydrawer. That way i created unity timer

 

Hello! Does anybody could draw parameters for the UnityEvent with your own custom editor or drawer, I was looking for the way of adding several parameters to the UI UnityEvents in the inspector but without avail.

If anyone has already achieved this already with UnityEvents please share, I already was using several parameters when I was using NGUI's EventDelegate but it seems Unity did not take into account having a list of parameters for each event. Right now the UnityEvent editor only shows in the inspector functions with one parameter only...

If anyone is interested there is a cool debate on this thread.

 

I have been looking at this but I don't see where you defined serializedObject.

Thanks,

it helps me so much, thx
