How to display text using javascript ?

Question

How am I supposed to display text when an object is triggered ? Example, I have an object and as soon as the player touches it, some text should be displayed. I have the following code:-

 var mess="Petite";
 function OnTrigggerEnter(other:Collider)
 
 {
         GUI.Label (Rect (10, 30, 1000, 20),"Word: " +mess);
 }

`GUI` functions can only be called from `OnGUI()`.

So usually people will manage state in Update or using triggers, then render according to state in OnGUI().

This script could be placed on an item in your level, and will display a message if the player (as identified by the tag system) is within it's trigger collider.

 public var mess: String = "Petite";
 private var inRange: boolean = false;
 
 function OnTriggerEnter(other:Collider) {
     if (other.tag == "Player") {
         inRange =  true;
     }
 }
 
 function OnTriggerExit(other:Collider) {
     if (other.tag == "Player") {
         inRange =  false;
     }
 }
 
 function OnGUI() {
     if(inRange) {
        GUI.Label (Rect (10, 30, 1000, 20),"Word: " +mess);
     }
 }

Is your player tagged "Player"?

Sorry I had a typo: "OnTrigggerEnter" with 3 "G"s.

I have corrected the code in my answer and tested it in the application.

When I increase the text size, the text gets displayed twice.

Why is it so.

This is the code I used-:

 var myStyle = new GUIStyle();
 public var mess: String = "Petite";
 private var inRange: boolean = false;
 
 function OnTriggerEnter(other:Collider) 
 {
     if (other.tag == "Player")
     {
         inRange =  true;
     }
 }
 
 function OnTriggerExit(other:Collider) 
 {
     if (other.tag == "Player") 
     {
         inRange =  false;
     }
 }
 
 function OnGUI() 
 {
     if(inRange)
     {
        myStyle.fontSize=50;
        GUI.Label (Rect (10, 30, 1000, 20),"Word: " +mess,myStyle);
     }
 }

And the text gets displayed like this-:

alt text

Is there any way to make it display only once

Please answer fast

@varunstorm now that you have the other question on GUI Text Formatting that is the appropriate place for this follow up question.

Please note that your images are appearing broken in both places so nobody can see what you are talking about.
