Custom Event Handler in Inspector?

Question

So in a UI Button, there's a nice and handy OnClick field where you can add objects and a function attached to the object to call, so that when the button is pressed all of the functions in the OnClick will be called.

Is there a way where I can use this feature to store functions and have it so I can call a function that calls all of the stored functions? Something like

 this.eventhandler.callAll();

@wontonst Crikey - I hope it's not too late to answer this, but I was hunting around to remind myself how to do this as it's been a while and couldn't remember the magic words. :)

Anyway, it's easily done:

 using UnityEngine.Events;
 
 public UnityEvent yourCustomEvent;
 
 public void Foo() {
     // Trigger the event!
     yourCustomEvent.Invoke();
 }

Here's more info.

Unfortunately this doesn't work if the object is being handle by a custom inspector. I imagine there is a EditorGUILayout.EventField(yourCustomEvent) but I cannot find one.

@sotirosn It works using Custom inspector. You just have to use serialized property EditorGUILayout.PropertyField (eventTest_Prop);

The Editor Script should looks like this:

     using UnityEngine;
     using UnityEditor;
         
         [CustomEditor(typeof(YourScriptName)), CanEditMultipleObjects]
         public class YourScriptNameEditor : Editor {
         
             public SerializedProperty yourCustomEvent_Prop;
         
                 void OnEnable () {
                      yourCustomEvent_Prop = serializedObject.FindProperty ("yourCustomEvent");
                 }
     
                 public override void OnInspectorGUI () {
                      EditorGUILayout.PropertyField (yourCustomEvent_Prop);
 
                      serializedObject.ApplyModifiedProperties ();
                }
             }

Works like a charm. For some other examples from Unity check this out: property-drawers-custom-inspectors

Don't to forget to call base.OnInspectorGUI(); if you do the above. Else all the other SerializeFields are not exposed to the editor. So:

 public override void OnInspectorGUI() {
     base.OnInspectorGUI();
     EditorGUILayout.PropertyField(onPublishProperty);
     serializedObject.Apply$$anonymous$$odifiedProperties();
 }

In my case works correctly the variant

 public override void OnInspectorGUI()
 {
     base.OnInspectorGUI();
     //EditorGUILayout.PropertyField(yourCustomEvent_Prop);
     serializedObject.ApplyModifiedProperties();
 }

In other case the field in Inspector double. And Don't forget:

The script "YourScriptNameEditor" must be in folder Assets\Editor and named as "YourScriptNameEditor.cs"
In "typeof(YourScriptName)" - YourScriptName - name of script where you use the "yourCustomEvent"
"yourCustomEvent" - It's the name of your event

all other can be unchangeable
