I had a bug, the ones on the top wouldn't work.

I would have thought the rotation was previously set. This could be done with the following: <Code Omitted>This should initialize those actors placed along the top of the world to move vertically (using the code I previously gave above). Note that the rotation could otherwise be set from the world:

Line 17 creates a new Ground object whose boolean will be true until another Ground object is created (by this new one). So, each Ground object will create the next one when needed.

1: with the line of code you provided "Greenfoot.setWorld(new QuestionWorld(this));", can you put it into a method in the maze class that returns a variable that stores that instances of the world? So that we can access it in other classes?

Unnecessary. "this" IS that instance of the maze world when used in the MazeWorld class.

2:what if the ...new QuestionWorld () is being called in an Actor subclass? Because of that line that creates a new QuestionWorld we have something similar already but it's in the smooth mover subclass that I have created.

I'm talking about learning Java using Greenfoot.

Greenfoot IS Java. Its classes are provided to allow a beginner to start creating games and simulations right from the start. I believe you are correct in that the tutorial should mention how you can inspect an object in greenfoot. Right-clicking on the world and selecting Inspect on the pup-up will show all field values, not just from in MyWorld, but also from in World. The same goes for an Actor object. Inspecting an actor will show fields provided in the Actor class (namely:

my problem is that, at the moment they are each doing the same movement but I will change that later and if I put it in the Actor class they all must move the same way

Lines 4 thru 8 are executed every act step. Therefore, on act steps that do not have tme%100 equal to 0, you are not working with the actors in the world in lines 26 thru 40. Note: I am kind of surprised that you are not getting errors on the move lines between 26 and 40 as the actors should be in the world for move to find their locations in the world. Create the No
