Wait inside method until user action

Questions & Answers
1

Hello there! I need to wait until user click button and set some value. This value is needed in another class as shown below. I have no idea how to implement. I’ve tried to use coroutines but no matter what I do Method1 always returns value before it is set by user. I’ve also tried do…while but obviously it freezes program.

class Class1{
    if(Class2.Method1())
        //do something
    else 
       //do something else
}
  • class Class2{
    bool Method1() {
    ShowDialog();
    WaitUntilUserSetValue();
    CloseDialog();
    return value;
    }
    }
    Any help & tips are welcome!

Thank you for your further explanation in the comments below. I edited this answer depending on your information. Try it, i hope it will work, i haven’t tested it.

public class Class1 : MonoBehaviour {

    public GameObject confirmationDialog;       // To set in inspector
    public GameObject gameObjectToDelete;       // To set in inspector


    private bool clickedYes = false;
    private bool clickedNo = false;

    // Function is called if the object has du be deleted
    public void onDeleteClick()                 
    {
        StartCoroutine(deleteGameObject(gameObjectToDelete));
    }

    IEnumerator deleteGameObject(GameObject obj)
    {
        clickedNo = false;
        clickedYes = false;
        confirmationDialog.SetActive(true);

        while (clickedYes == false && clickedNo == false)
        {
            yield return 0;
        }

        confirmationDialog.SetActive(false);
        Destroy(gameObjectToDelete);            // ... or delete file ... or anything else
    }

    // function is called when button yes is clicked in the confirmation Dialog (Event)
    public void confirmationDialogClickedYes()          
    {
        clickedYes = true;        
    }

    // function is called when button no is clicked in the confirmation Dialog (Event)
    public void confirmationDialogClickedNo()           
    {
        clickedNo = true;
    }
}

Thanks to you I finally found working solution. Here is pseudocode. Maybe someday will be helpful for someone.

class Class1 {
     void onButtonClicked(){
          Class2.Method1(Action SomethingToDo);
     }
     void SomethingToDo(){
          ...
     }
}

  • class Class2 {
    Action actionToDo;
    bool userClicked = false;
    bool confirmed;

       void Method1(action){
        actionToDo = action;
        ShowDialog();
        StartCoroutine(WaitForUserConfirm());
   }
   IEnumerator WaitForUserConfirm(){
        yield return new WaitUntil(() => userClicked);
        if(confirmed)
             actionToDo();
        CloseDialog();
   }
   void onConfirmButtonClicked(){
        userClicked = true;
        confirmed = true;
   }
   void onDeclineButtonClicked(){
        userClicked = true;
        confirmed = false;
   }

    }
