Description

One argument version of UnityEvent.

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

#pragma strict

class MyIntEvent extends UnityEvent.<int> {}

var m_MyEvent : MyIntEvent;

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

m_MyEvent.AddListener (Ping); }

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

function Ping (i: int) { Debug.Log ("Ping" + i); }
using UnityEngine;
using UnityEngine.Events;

[System.Serializable] public class MyIntEvent : UnityEvent<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); } }
