Firstly, the loop will never work. If no actors are in world, then no looping will take place. If any number of actors are in the world, the loop is broken out of immediately by the conditional expression (with s starting at zero, s+1, or 1 will be less than or equal to number of actors in world). Secondly, I do not see any code that attempts to acquire the x and y values of any actor's location.

so, the loop starts now and I added in my failed attempts to get the coordinates, but they don't work. And sorry if I'm bad at coding, I'm pretty much a beginner. I also want to add that I think the problem is that looking for objects in class null just don't have the properties of an actor

You should only use getObjects once in this snippet. You can assign the returned list to a List variable, or even better, use the for-each loop structure: As far as the properties of the objects in the returned list, they are there; however, it is not known to look in the Actor class for the getX and getY methods. To have these methods be found, the objects need to be cast as of type Actor (via typecasting): After executing this line, you can use 'actor.getX()' and 'actor.getY()', as well as 'actor.getClass().getCanonicalName()'.
