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 will be serialized and displayed in the inspector. ![persistent](https://user-images.githubusercontent.com/12690315/40887795-f5eb7ac4-6788-11e8-9e73-6831e3eab08f.png) * **Runtime call** * You can add a callback from a script with *UnityEvent.AddListener*. * It will be **not** serialized and displayed in the inspector. ![runtime](https://user-images.githubusercontent.com/12690315/40887784-c8c2027a-6788-11e8-83f7-07e38e187cba.png) ### Display your runtime calls This package extends *UnityEventDrawer* to display runtime calls in the inspector. If the runtime call is an instance method, its target is also displayed. This plugin supports all events that inherit `UnityEvent - UnityEvent` as well as *UnityEvent*. Even if the persistent call is empty, *UnityEvent* is displayed compactly in the inspector. ```cs public class TestBehavior : MonoBehaviour { [System.Serializable] public class TransformUnityEvent : UnityEngine.Events.UnityEvent{}; [SerializeField] TransformUnityEvent onYourCustomEvent = new TransformUnityEvent(); void OnEnable() { onYourCustomEvent.AddListener(TestTransform); } void TestTransform(Transform t) { Debug.Log("TestTransform has called : " + t); } } ``` ![image](https://user-images.githubusercontent.com/12690315/40887986-d0c2af58-678b-11e8-953c-63116ab2b433.png) If you like a style of development that makes heavy use of runtime calls (MVP pattern, etc.), this package is for you!
