HI,

My code seems to crash unity I suspect its the while loop not being able to end any suggestions.
#pragma strict

var changeCircleColor : int = 1;
var circleColor : String;
var gameState : String;
        
function Start ()
{
    Debug.Log("The game has started");
    gameState = "play";
}
  
function Update ()
{
    while (gameState == "play") 
    {   
        ChangeCircleColor();
        if(Input.GetKeyDown(KeyCode.Space))
        {
            gameState == "stop";
        }
    }
}

function ChangeCircleColor ()
{
    if(changeCircleColor == 1)
    {
        gameObject.GetComponent.<Renderer>().material.color = Color.green;
        circleColor = "green";
        changeCircleColor = Random.Range(1,2);
    }
    if(changeCircleColor == 2)
    {
        gameObject.GetComponent.<Renderer>().material.color = Color.red;
        circleColor = "red";
        changeCircleColor = Random.Range(1,2);
    }
}

Tnx Adam

The Update method is called every frame - your codes getting stuck in the While loop because Unity hasn’t been given the chance to check for an input from a user so it won’t detect that the key has been pressed. You don’t need a ‘While’ loop it’s not needed. Remove it and it should work fine :slight_smile:

function Update ()
 {
         ChangeCircleColor();
         if(Input.GetKeyDown(KeyCode.Space))
         {
             gameState == "stop";
         }  
 }
