Question

I’m working on a project in Unity using C# scripting. The GUI.Box will appear at the top the screen. The box will disappear when the player leaves the spot. How can I make the box stay there for an additional 3 seconds after the player leaves the designated spot?

Danpe’s code corrected (working code):

bool shown = false;

void OnGUI () {
if (car.transform.position.y>=43 && car.transform.position.y<=44)
{
    shown = true;
}
else if (shown)
{
    StartCoroutine(DisapearBoxAfter(3.0f)); 
}
if(shown) 
{
    GUI.Box(new Rect((Screen.width/2)-200,0,400,30) , "King of the hill");
}
}

IEnumerator DisapearBoxAfter(float waitTime) { 
// suspend execution for waitTime seconds
yield return new WaitForSeconds(waitTime);
shown = false;
}




void Update () {
    OnGUI ();
}

bool shown = false;

void OnGUI () {
    if (car.transform.position.y>=43 && car.transform.position.y<=44)
    {
        shown = true;
    }
    else if (shown)
    {
        StartCoroutine(DisapearBoxAfter(3.0)); 
    }
    if(shown) {
        GUI.Box(new Rect((Screen.width/2)-200,0,400,30) , "King of the hill");
    }
}

IEnumerator DisapearBoxAfter(float waitTime) {
    // suspend execution for waitTime seconds
    return yield WaitForSeconds (waitTime);
    shown = false;
}


void Update () {
    OnGUI ();
}
