How do you make a blinking GUI?

var instanceMet : boolean = true;

static var flashTexture : boolean = false;

InvokeRepeating ("checkGUI", 0.001, 0.30);

function flashGUI () {
	yield WaitForSeconds(0.075);
	guiTexture.color.a = 0.125;
	yield WaitForSeconds(0.075);
	guiTexture.color.a = 0.250;
	yield WaitForSeconds(0.075);
	guiTexture.color.a = 0.375;
	yield WaitForSeconds(0.075);
	guiTexture.color.a = 0.250;
}

function checkGUI() {
	if (instanceMet) {
		flashGUI();
		flashTexture = true;
	} else {
		flashTexture = false;
		guiTexture.color.a = 0.375;
	}
}

Not very conventional I know, but it does the job.

This particular code is untested by the way.

EDIT: Yeah, sorry, I was thinking GUITexture there for some deranged reason.

/* Flashing button example */

function OnGUI () {
	if (Time.time % 2 < 1) {
		if (GUI.Button (Rect (10,10,200,20), "Meet the flashing button")) {
			print ("You clicked me!");
		}
	}
}

Here’s one way of doing it:

using UnityEngine;
using System.Collections;

public class MyBlinkingThingy : MonoBehaviour
{
	public Rect m_LabelRect = new Rect (0, 0, 200, 20);
	public string m_Label = "Blink!";
	public float m_BlinkFrequency = 2.0f;
	
	private bool m_Show = true;
	
	
	IEnumerator Start ()
	{
		// Initialize stuff here
		while (Application.isPlaying)
		{
			yield return new WaitForSeconds (1.0f / m_BlinkFrequency);
			m_Show = !m_Show;
		}
	}
	
	
	void OnGUI ()
	{
		if (!m_Show)
		{
			GUI.color = new Color (1, 1, 1, 0);
		}
		GUI.Label (m_LabelRect, m_Label);
		GUI.color = Color.white;
	}
}
