Hello. I’m trying to get my GUI to off after 3 seconds but it’s not working. My GUI stays on all the time after hitting the cube. I tried to use the yield statement in the OnGUI function but it ends up turning the GUI off entirely. How do I off it after a certain amount of time? Thank you.

Here’s my code:

#pragma strict

var showGUI = false;

var otherScript : PlayerRelativeControl;
var increase = 5.0;
var temporarySpeed = 0.0; 
var speedBoostDuration = 4;
var nextActivationTime = 0.0;

private var timer = 0.0;
private var horizontalSpeed = Input.GetAxis("Horizontal");
private var verticalSpeed = Input.GetAxis("Vertical");

function Update()
{

	rigidbody.mass = 0.1;
	var otherScript = GetComponent(PlayerRelativeControl);
	
}

function OnControllerColliderHit (collisionObject: ControllerColliderHit)
{ 
	if(collisionObject.gameObject.name == "Cube" && Time.time > nextActivationTime) 
	{ 
		
		nextActivationTime = Time.time + speedBoostDuration;
		Destroy(collisionObject.gameObject); 
		
			temporarySpeed = otherScript.forwardSpeed +increase;
			showGUI  = true;
			yield WaitForSeconds(3);
			temporarySpeed = otherScript.forwardSpeed;
		
		
		rigidbody.AddTorque(Vector3(0,horizontalSpeed,verticalSpeed) * 10); 
		rigidbody.AddForce (Vector3(temporarySpeed,0,0));
		
		showGUI = false;
		
	} 
	
	
}

	
function OnGUI () 
{
	if(showGUI)
	{
	
		GUI.enabled = showGUI;
		GUI.Label (Rect (Screen.width/2, Screen.height/3, 600, 40), "Speed Increase!");
		
	}

}

Thank you. Cheers.

I tested this script in my PC, and it produced some runtime errors; when I fixed them, it worked fine. The errors were:

1- You should remove var from the line where you get otherScript via GetComponent - this keyword was creating a temporary variable, so the public otherScript never was assigned. By the way, you should place this code in Start, since it only needs to be executed once;

2- You must move both Input.GetAxis to the Update function (or any other). Input.GetAxis outside any function produces a runtime error.

All the changes were situated at the same region, so I show below only the modified part of the code:

...
private var timer = 0.0;
private var horizontalSpeed: float;
private var verticalSpeed: float;

function Start(){
    rigidbody.mass = 0.1;
    otherScript = GetComponent(PlayerRelativeControl);
}

function Update(){
    horizontalSpeed = Input.GetAxis("Horizontal");
    verticalSpeed = Input.GetAxis("Vertical");
}
