public void AddListener(UnityAction call)
Parameters
The callback function to execute when the event is invoked.
Remarks
This method registers a listener for the UnityEvent at runtime. If the same listener is added multiple times, it is invoked only once per event.
//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 OnKeyPressed method when invoked m_MyEvent.AddListener(OnKeyPressed); } void Update() { // Press Q to close the Listener if (Input.GetKeyDown("q") && m_MyEvent != null) { Debug.Log("Quitting"); m_MyEvent.RemoveListener(OnKeyPressed); #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 OnKeyPressed() { //Output message to the console Debug.Log("Q key pressed"); }}
