| call | Callback function. |
Add a non persistent listener to the UnityEvent.
Use this to add a runtime callback. Adding multiple identical listeners results in only a single call being made.
//Attach this script to a GameObject //This script creates a UnityEvent that calls a method when a key is pressed //Note that 'q' exits this application. using UnityEngine; using UnityEngine.Events;
public class Example : MonoBehaviour { UnityEvent m_MyEvent = new UnityEvent();
void Start() { //Add a listener to the new Event. Calls MyAction method when invoked m_MyEvent.AddListener(MyAction); }
void Update() { // Press Q to close the Listener if (Input.GetKeyDown("q") && m_MyEvent != null) { Debug.Log("Quitting"); m_MyEvent.RemoveListener(MyAction);
#if UNITY_EDITOR UnityEditor.EditorApplication.isPlaying = false; #endif
Application.Quit(); }
//Press any other key to begin the action if the Event exists if (Input.anyKeyDown && m_MyEvent != null) { //Begin the action m_MyEvent.Invoke(); } }
void MyAction() { //Output message to the console Debug.Log("Do Stuff"); } }
