Help needed!

I want a my game over screen to be displayed, after my player controller remains in a trigger zone for about 0.5 second. How can I do that?

Hello. First, I assume that you already know how to make your “Trigger Zone” by using “Is Trigger” on a collider. To make actions for that trigger, you must attach a script on the Is Trigger GameObject, that uses OnTriggerEnter function. Here is an example:

var triggerTime = 0; //variable for time in trigger.

var endGameTime = 5; //variable for time to end the game.

function OnTriggerEnter ( other : Collider){
         if (triggerTime == endGameTime){
               //Your end game action goes here. Example:

            application.Load ("end game");

//Update function for time variable

function Update (){
triggerTime += 1 * Time.deltaTime;
