What happens when the wombat gets to the edge of the world (which way does it turn)? which way does it then move? what about when it reaches the next edge?

Just how the code currently works. Change it if you want.

Gotta' leave something for you to build your programming skills on.

Increase the value of the argument in the move command.

The wombat is not coded to move away from the edge of the world once it is arrived at. So, any leaves remaining in the interior of the world will not then be found.

First, the act method will have the wombat do one of 3 things. In order, it will either (1) eat; (2) move or (3) turn (see lines 24 through 32). In order to move, the returned value of canMove must be true (lines 27 through 29, specifically). The canMove method returns true only if the wombat is not facing a wall. As previously mentioned, if the wombat does not move, it will turn (left, specifically). Therefore, once the wombat finds an edge, it will turn to move counter-clockwise along the edges of the world.

First create a subclass of Actor and give it an image or have it create one. In you run into problems with your code, then post what you ended up with for help.

We did have a bug in the GifImage class which meant that certain GIFs did not clear their image properly between frames. This is fixed in Greenfoot 3.5.3 -- you'll need to install the new version, delete the GifImage class in your scenario, and re-add it via the Import Class functionality. That should hopefully fix the issue.

Try stopping the scenario and mouse drag each wombat.around.

You will need to show the Wombat class code that goes with this question.

As far as inheriting Actor, you will need an Actor object to display the button in greenfoot unless you modify the background image o

When I said: you responded with Did you not see a bunch of null values (for the images)? Would that not seem off?

<Code Omitted>This is the code I came up with, when seeing your project and your problem. You need to put it into the sprite class I hope it will help you. (I didn't test it)

<Code Omitted>Hey 343qwm29, I hope this line of code will help you... A little hint: When you don't know how to do something, but you have an idea what your code has to do, go to your Greenfoot Scenario and click on "Help" and then on "Greenfoot Class Documentation" where you can find almost every method that Greenfoot has, and how to use it.
