#토글 누를때마다 이벤트 체크하기

- CTest1클래스를 Toggle UI의 컴포넌트에 넣자.

- 아래 코드와 같이 "onValueChanged.AddListener(...)" 에 이벤트로 들어온 값을 확인하면 된다.

 

CTest1  : MonoBehaviour

{

     Toggle _toggle = null;

 

      void Start()
      {
        _toggle = gameObject.GetComponent<Toggle>();
        _toggle.gameObject.SetActive(true);
        _toggle.onValueChanged.AddListener(
            (bool bOn) => 
            {
                bool val = bOn; //누루는 이벤트 마다 값이 들어온다.
            }
        );
      }

}

Adding a listener to Toggle.onValueChanged via Script

Hello,

I was trying to add a listener on a Toggle Button but i am not able to write that. Can anybody please help me. Here is what i am doing

1. Toggle sound = GameObject.Find("soundOnOff").GetComponent();
2. sound.onValueChanged.AddListener(gameSoundStatusChanged); // --- Error
3.  

and the function is

1. public void gameSoundStatusChanged()
2. {....}
3.  

it says .addlistener has some invalid parameters. Cause it asks for parameter of type UnityAction function. Please help me on how to write the function in given syntax.

I just had the same issue. You just need to pass a float parameter into your method. eg.

1. public Slider myMusicVolumeSlider;
2. AudioSource myBGMusic;
3.  
4. void Start ()
5. {
6. myBGMusic = GetComponent<AudioSource>();
7. myMusicVolumeSlider.value = 0.2f;
8. myMusicVolumeSlider.onValueChanged.AddListener(RaiseVolume);
9. }
10.  
11. void Update ()
12. {
13. //I Don't want to run this every frame....
14. //myBGMusic.volume = myMusicVolumeSlider.value;
15. }
16.  
17. public void RaiseVolume(float value)
18. {
19. myBGMusic.volume = myMusicVolumeSlider.value;
20. //Or even just... myBGMusic.volume = value;
21. }
22.

AddListener to a Toggle.

Hello. I would like to attach a listener to checkbox:

1. void Start ()
2. {
3. GameObject cb1 = (GameObject)Instantiate(cbPrefab);
4.  
5. Toggle t = cb1.GetComponent<Toggle>();
6. t.onValueChanged.AddListener(() => handleCheckbox(value)); **error here**
7. }
8.  
9.  
10. void handleCheckbox(bool value)
11. {
12. print("handleCheckbox. value=" + value);
13. }
14.  
15.  

The compile error that I get is:

1. error CS1593: Delegate `UnityEngine.Events.UnityAction<bool>' does not take `0' arguments
2.  
3.  

Could somebody help me to fix this? Thanks!

1. t.onValueChanged.AddListener ( (value) => { // you are missing this
2. handleCheckbox(value); // this is just a basic method call within another method
3. } // and this one
4. ); // closing the AddListener method parameter
