Gui Text Help

I am trying to make a set of instructions pop up on the screen. My one problem is that I am trying to call a UI text object in the game and I am trying to make the text be disabled then when I enter a trigger it is enabled. It is not working though. I also tries to use OnGUI and I don’t know how to use a function in another function

Here’s an example of code where it works:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class Triggertext : MonoBehaviour {

	public Text text;

	void OnTriggerEnter () {

		text.text = ("Hello");
	}
}

Your mistake was probably that you didn’t tell the script to use UnityEngine.UI, which is essential when doing anything script-controlled on a canvas. Hope this helped.
