GUIText which corresponds with a GUIBox

Questions & Answers

I’m making a game where a player clicks an object eg. bed and has to type what it is into a GUITextField. There are ten words per scene and I want to create a GUIBox in each which charts the entering of each word and when entered correctly/incorrectly the adjoining word changes to green/red. My code thus far is below. Thanks in advance.
using UnityEngine;
using System.Collections;

public class Bed : MonoBehaviour {

	public bool clickedBed = false;
	public string bed = "Type Here";

	void OnGUI() {
		if (clickedBed) {
			bed = GUI.TextField (new Rect (200, 78, 200, 20), bed, 25);
		}
	}

	void OnMouseUpAsButton() {
		Debug.Log ("Mouse DOWN!!!");
		clickedBed = true;
	}

	void Update() {
		if (Input.GetKeyUp (KeyCode.Return)) {
			clickedBed = false;
			// TODO proces guess
		}
		if (Input.GetMouseButton (0)) {
			Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
			RaycastHit hitInfo = new RaycastHit();
			if (Physics.Raycast(ray, out hitInfo, 100.0f)) {
				if (hitInfo.collider.gameObject.Equals(gameObject)) {
					Debug.Log ("Mouse Clicked!!!");
					clickedBed = true;
				} else {
					GameObject go = hitInfo.collider.gameObject;
					while (go.transform.parent != null) {
						go = go.transform.parent.gameObject;
						if (go.Equals(gameObject)) {
							Debug.Log ("Mouse Clicked!!!");
							clickedBed = true;
						}
					}
					//Debug.Log ("Hit: " + hitInfo.collider.gameObject);
					//Debug.Log ("Should Hit: " + gameObject);
				}
			}
		}
	}

If your specific question is about changing color, as far as I know, you cannot change the color of a GUI.Box(). You can change the background texture, but if you were going to do that, you might as well use GUI.DrawTexture() instead, and use a red or a green texture. So that is the place to start. It would be best to have an array of boolean values that you could set to true when you wanted green. Example code. Put it on an empty game object in a new scene, initialize redTexure and greeTexture in the Inspector, and hit play:

#pragma strict

var redTexture : Texture2D;
var greenTexture : Texture2D;
var startRect = Rect(10,10,40,40);
var padding = 3;

private var state : boolean[] = new boolean[10];

function Start() {
	state[3] = true;
	state[5] = true;
	state[8] = true;
}

function OnGUI() {
	var rect = startRect;
	
	for (var i = 0; i < state.Length; i++) {
		var tex = (state*) ? greenTexture : redTexture;*

  •  GUI.DrawTexture(rect, tex);*

  •  rect.x += rect.width + padding;*
  • }*
    }
