Thread: GridWorld

I'm reading the book 'Thinking in Java' and I'm at the first gridworld stage, I've installed gridworld though my version is different to the books, mainly there is no Rock.
What do you guys think I should do?

thank you for replying, well what I have downloaded is different from all the exercises in the book so do you know of any tutorials on gridworld that take into account changes the case study has gone through?
Feel free to recommend anything other than gridworld that may help me as a beginner.

no.

Find a matching version of the book or software.
Perhaps design your own Rock to substitute.
I do not know anything about gridworld either but that does not mean you can't find help here.
You never say what is wrong with the code. You say there is no rock, but to people unfamiliar with gridworld, what is a rock? Is it a class? Or a variable? Perhaps a package?
Is there a compiler error or runtime error? Always post the full text of errors with your question and code.
What we need to be able to help you is a description of the problem, what works and what does not. What did you expect the code to do as you have written it, and what does it actually do?
If you can not explain better what is wrong, then my final suggestion would be to not play with broken toys just yet, and find an educational tool without internal errors
