Unity 5 - Input Field - How to confirm password entry with ENTER only and not a click/loss of focus

Question

I have an input field password box, currently the password is 'submitted' either by clicking Enter or by clicking elsewhere on the screen. This seems to be the designed way, as it states this in the documentation (https://docs.unity3d.com/Manual/script-InputField.html) -

"A UnityEvent that is invoked when the user finishes editing the text content either by submitting or by clicking somewhere that removes the focus from the Input Field."

As I have other buttons on the same screen that users can click on, I would like it so mouse clicks are not counted as an invoke.

Is this possible?

Many thanks in advance

Answer 1

You could use this method to check if the password is correct every time a new character is entered into the text field

https://docs.unity3d.com/ScriptReference/UI.InputField-onValueChange.html

You may want to add some checks before seeing if it is correct, like only checking once password is over minimum length so that you don't send unnecessary requests to the login server.

Simple solution:

using UnityEngine;
using UnityEngine.UI;

public class CustomSubmit : MonoBehaviour
{
    public Button SomeButton;
    public InputField Field;
    private bool wasFocused;

    private void Awake()
    {
        SomeButton.onClick.AddListener(() => {
            Submit(Field.text);
        });
    }

    private void Update()
    {
        if (wasFocused && Input.GetKeyDown(KeyCode.Return)) {
            Submit(Field.text);
        }

        wasFocused = Field.isFocused;
    }

    private void Submit(string text)
    {
        Debug.Log("Submit=" + text);
    }
}
