I have been trying to use the getObjects().length(); I saw this being used somewhere and thought it was possible but I am unable to get it to work. Is there a way to count objects in of just one class?

First, the 'getObjects' method needs a class or null for a parameter; second, it returns a List object and there is no 'length' method that can be used on a List object. It does have a 'size' method, so you could do this:

1	`int` `actorCount = getObjects(Actor.class).size();`

You can replace 'Actor' with the name of any subclass of Actor to be more specific.

Thank you very much I wanted to use the .size but didn't know it.

Is there a way to count objects of a specific Class, or even multiple classes?
