[英]How to access the OnClick event via Script
I am trying to do a SongManager object which will be responsible for changing songs. 我试图做一个SongManager对象,它将负责更改歌曲。 I created a SongManager and a Song script.
我创建了一个SongManager和一个Song脚本。 On runtime SongManager creates as many song buttons as i want each with different variables.
在运行时,SongManager会根据需要创建尽可能多的歌曲按钮,每个按钮都具有不同的变量。 Everything seems to work fine except that i cant get to OnClick event to change the songs.I tried many things but i guess its all outdated.
除了无法通过OnClick事件更改歌曲以外,其他所有内容似乎都正常运行。我尝试了很多尝试,但我想一切都已经过时了。 Stuff like:
像这样的东西:
public Button.ButtonClickedEvent OnClickEvent;
or 要么
go.GetComponent<Button>().onClick.AddListener();
Appreciate any help, thank u guys. 感谢您的帮助,谢谢大家。
You can use Events for comminucation with your other classes. 您可以将事件与其他类一起使用。 Here is the code :
这是代码:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class SongButton : MonoBehaviour {
public delegate void SongButtonEvent(int index);
public static event SongButtonEvent OnSongButtonClick;
void ClickSongButton(){
if (OnSongButtonClick != null)
OnSongButtonClick (index);
}
public Button button;
public Text songName;
public int unlocked;
public AudioClip clip;
public int index;
void Start () {
button.onClick.AddListener (ClickSongButton);
}
public void Initialize(int index,Song song){
this.index = index;
songName.text = song.songName;
unlocked = song.unlocked;
clip = song.clip;
button.interactable = song.isInteractable;
}
}
First of all, i create a Initialize method. 首先,我创建一个Initialize方法。 It uses Song object variables for initialization and takes an index as button id.
它使用Song对象变量进行初始化,并使用索引作为按钮ID。 After i create an event for notify listeners with index.
在我创建一个事件以通知索引的侦听器之后。
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.Collections.Generic;
[System.Serializable]
public class Song
{
public string songName;
public int unlocked;
public bool isInteractable;
public AudioClip clip;
}
public class SongManager : MonoBehaviour
{
public SongButton button;
public Transform panel;
public List<Song> songList;
void OnEnable(){
SongButton.OnSongButtonClick += SongButton_OnSongButtonClick;
}
void OnDisable(){
SongButton.OnSongButtonClick -= SongButton_OnSongButtonClick;
}
void SongButton_OnSongButtonClick (int index)
{
Debug.Log ("index : " + index + " - song name : " + songList [index].songName);
}
void Start ()
{
FillList ();
}
void FillList ()
{
for (int i = 0; i < songList.Count; i++) {
SongButton songButton = Instantiate (button) as SongButton;
songButton.Initialize (i, songList [i]);
songButton.transform.SetParent (panel, false);
}
}
}
When SongManager became enable, it starts to listen to OnSongButtonClick events. SongManager启用后,它将开始侦听OnSongButtonClick事件。 This way, you can know which button clicked.
这样,您可以知道单击了哪个按钮。
I hope it helps. 希望对您有所帮助。
You pass in the function name to the AddListener
parameter. 您将函数名称传递给
AddListener
参数。
public GameObject go;
Button myButton = null;
void Start()
{
myButton = go.GetComponent<Button>();
myButton.onClick.AddListener(() => myCallBackFunction());
}
void myCallBackFunction()
{
Debug.Log("Button Clicked!");
}
You can also do: myButton.onClick.AddListener(delegate { myCallBackFunction(); });
您还可以执行以下操作:
myButton.onClick.AddListener(delegate { myCallBackFunction(); });
