GUIText dissapear after a few seconds
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;
}
ok, this is the true answer... $$anonymous$$ark it as true answer... i `m lose now :)
I guess this would work but the text is still there for me. I'm using this script for a battery pick-up. The trigger destroys after I walk in to the triggered area and then the text pops up. Can the problem be that the trigger destroys or what?
Don't destroy the trigger, because then the script is destroyed with it and the code can't run because it doesn't exist anymore.
But I just want to use the trigger once, not multiple times
Don't destroy it until after the script is no longer needed, then.
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;
}
