Extend the UnityEventDrawer to display runtime calls in the inspector.

<< Description | Demo | Installation | Usage | Development Note | Change log >>

Button.onClick and Toggle.OnChangeValue etc. are known as UnityEvent.
UnityEvent has two types of callbacks:

• Persistent call
  • You can add callbacks from the inspector.
  • You can add callbacks from a script using UnityEventTools.AddPersistentListener.
  • It is Serialized.
  • It is displayed in the inspector.
    
• Runtime call
  • You can add a callback from a script using UnityEvent.AddListener.
  • It is not serialized.
  • It is not displayed in the inspector.
    

This plugin extends UnityEventDrawer to display runtime calls in inspector.
If runtime call is an instance method, its target is also displayed.
This plugin supports all events that inherit UnityEvent<T0> - UnityEvent<T0, T1, T2, T3> as well as UnityEvent.
Also, when the Persistent call is empty, UnityEvent is displayed compactly in inspector.

public class TestBehavior : MonoBehaviour
{
	[System.Serializable] public class TransformUnityEvent : UnityEngine.Events.UnityEvent<Transform>{};

	[SerializeField] TransformUnityEvent onYourCustomEvent = new TransformUnityEvent();
	
	void OnEnable()
	{
		onYourCustomEvent.AddListener(TestTransform);
	}
	
	void TestTransform(Transform t)
	{
		Debug.Log("TestTransform has called : " + t);
	}
}

If you like a development style that heavily uses Runtime calls (MVP pattern, etc.), we recommend using this plugin!

• Displays runtime calls in inspector
• Expands/collapses the runtime call view
• Displays instance method, its target is also displayed
• When the Persistent call is empty, displays it compactly
• Supports pro skin
• Supports all components as well as uGUI components such as Button and Toggle
  
• Supports EventTrigger
  

• Unity 5.5 or later
