Instructions: How to do a focusable unfocusable text field

Unity Engine

Because I had a hard time getting this figured out and didn’t find a whole lot of help anywhere on the internet, I’m posting this here with hopes that others may find it useful.

Here’s how I set up my focusable text fields (using c#):

using UnityEngine;
using System.Collections;

public class FocusTextFieldExample : MonoBehaviour {
	//Set up holder variable for the contents of your text field.
	private string firstNameField;
	//Set up variable to hold the default value to revert back to upon losing focus while empty
	public string firstNameFieldDefault = "Enter First Name...";
	
	//Same stuff with a second set of variables
	private string lastNameField;
	public string lastNameFieldDefault = "Enter Last Name...";
	
	void Awake () {
		//You probably want to initialize your textfield text with the default text
		firstNameField = firstNameFieldDefault;
		lastNameField = lastNameFieldDefault;
	}
	
	void OnGUI () {
		//Optionally label your fields
		GUILayout.Label("First Name: ");
		//Run the custom FocusableTextField function created below
		//Make sure to plug in all 4 necessary variables
		FocusableTextField(firstNameField, out firstNameField, firstNameFieldDefault, "FirstNameField");
		
		//Same thing but with the second set of variables
		GUILayout.Label("Last Name: ");
		FocusableTextField(lastNameField, out lastNameField, lastNameFieldDefault, "LastNameField");
	}
	
	//Custom FocusableTextField function
	void FocusableTextField(string currentTextIn, out string currentTextOut, string defaultText, string fieldName) {
		//Give the text-field a nametag
		GUI.SetNextControlName(fieldName);
		//Create the text-field
		currentTextOut = GUILayout.TextField(currentTextIn);
		//Check if the text-field has gained focus
		if (GUI.GetNameOfFocusedControl() == fieldName  currentTextOut == defaultText) {
			currentTextOut = "";
		}
		//Otherwise, check if the text-field lost focus
		else if (GUI.GetNameOfFocusedControl() != fieldName  currentTextOut == "") {
			currentTextOut = defaultText;
		}
	}
}

Thanks! This is what I needed.
