Description

Two argument version of UnityEvent.

If you wish to use a generic UnityEvent type you must override the class type.

using UnityEngine;
using UnityEngine.Events;

[System.Serializable] public class MyIntEvent : UnityEvent<int, int> { }

public class ExampleClass : MonoBehaviour { public MyIntEvent m_MyEvent;

void Start() { if (m_MyEvent == null) m_MyEvent = new MyIntEvent();

m_MyEvent.AddListener(Ping); }

void Update() { if (Input.anyKeyDown && m_MyEvent != null) { m_MyEvent.Invoke(5, 6); } }

void Ping(int i, int j) { Debug.Log("Ping" + i + ", " + j); } }

Note: UnityEvent can also be awaited in any async method.
