[Solved] Javascript Class and Update

Unity Engine

I’m working on a class. I want to use Update. Update doesn’t get called in instances of the class. What am I doing wrong?

class ClassTest extends MonoBehaviour
{
	//////// properties
	private var timer : float;
	
	
	//////// methods
	// constructor
	function ClassTest()
	{
		Debug.Log("ClassTest Instantiated");
		timer = Time.time;
	}
	
	// update
	function Update()
	{
		Debug.Log("ClassTest Update");
		
		if (Time.time >= (timer + 1.0))
		{
			timer = Time.time;
			Debug.Log("Another second... " + Time.time);
		}
	}

}

Now that I think about it, I should be getting an error about trying to instantiate a class that extends MonoBehaviour using the “new” keyword, but I’m not. I create and instance of the class and I get “ClassTest Instantiated” in the console, no warnings. Weird.

OK, I got it. I was using new ClassTest(); to instantiate. I got the debug line about instantiation that way but never got updates.

I tried using AddComponent("ClassTest") instead of new and in the class instead of a constructor I used Awake and now Update works. Meh. Whatever gets it going is fine with me.

class ClassTest extends MonoBehaviour
{
   //////// properties
   private var timer : float;
   
   
   //////// methods
   // constructor
   function Awake()
   {
      Debug.Log("ClassTest Instantiated");
      timer = Time.time;
   }
   
   // update
   function Update()
   {
      Debug.Log("ClassTest Update");
      
      if (Time.time >= (timer + 1.0))
      {
         timer = Time.time;
         Debug.Log("Another second... " + Time.time);
      }
   }

}
