Making a UI.Button put text into a InputField

Questions & Answers
1

Hi, I am trying to make a UI.Button input a letter into the InputField when pressed. I have tried many different methods but none of them seems to work.

Secondly I also have a backspace button which I want to remove the last letter in the InputField which I also can’t get to work.

You don’t really need an input field just a text field will do it if you want to make a custom keyboard, this is in C#…

using UnityEngine;
using UnityEngine.UI;		// add at the top
using System.Collections;

public class MyKeyboard : MonoBehaviour {

	public Text myText;		// drag your text object on here
	private bool shiftOn = false;
	
	public void ClickLetter(string letterClicked)
	{
		string tempCurString = myText.text;
		
		if(shiftOn)
			letterClicked = letterClicked.ToUpper();
				
		string tempNewString = tempCurString + letterClicked;
		myText.text = tempNewString;
	}
	
	public void ClickBackspace()
	{
		string tempGetString = myText.text;
		if(tempGetString.Length > 0)
		{
			string tempString = tempGetString.Substring(0, tempGetString.Length -1);
			myText.text = tempString;
		}
	}
	
	public void PressShift()
	{
		shiftOn = !shiftOn;
	}
}

Drag that onto the panel your custom keyboard is on and add all your buttons, including Shift and Backspace. In the OnClick for each button click + and drag the panel with the script on it onto the slot that appears.

In the OnClick drop down for the letter/number buttons select MyKeyboard → ClickedLetter and set the string field to be the lowercase letter for that button.

On the Shift/Backspace do the same but select PressShift/ClickBackspace.

Don’t forget to drag the Text object onto the Panels Text field in that script.

Should work fine.
