Hi.
I was just wondering how to make a GUIText dissapear after a few seconds.
I have this script right now that triggers a GUIText when I walk over a triggered area.

var theGuiObject : GUIText; // set this in the inspector view

function OnTriggerEnter (other : Collider) {
    if (other.CompareTag ("Player")) {         
        theGuiObject.enabled = true;
    }
}

function OnTriggerExit (other : Collider) {
    if (other.CompareTag ("Player")) {         
         theGuiObject.enabled = false;
    }
}

You’d want to handle the case of the player entering the trigger, leaving, then re-entering.

var theGuiObject : GUIText;
var displayTime = 3.0;
private var timerActive = false;
private var timer = 0.0;

function OnTriggerEnter (other : Collider) {
    if (!other.CompareTag ("Player")) { // Do nothing if tag is not "Player"
        return;
    }
    if (timerActive) { // Reset timer if player re-enters trigger while the timer's active
        timer = 0.0;
        return;
    }
    
    theGuiObject.enabled = true; // Enable GUIText, wait a while, then disable it
    yield Wait();
    theGuiObject.enabled = false;
}

function Wait () { // A custom WaitForSeconds coroutine that can be reset
    timerActive = true;
    timer = 0.0;
    while (timer < displayTime) {
        timer += Time.deltaTime;        
        yield;
    }
    timerActive = false;
}

i think you can use yeild WaitForSeconds
maybe like this :

function OnTriggerEnter (other : Collider) {
    if (other.CompareTag ("Player")) {         
        theGuiObject.enabled = true;
        WaitToDisappear();
    }
}
function WaitToDisappear()
{
   yield WaitForSeconds(//set your time in here)
   theGuiObject.enabled = false;
}
