Hello, The problem is that this exercise have two worlds. You can switch between worlds by clicking on the combobox showing "Swiss cheese" in your interface. As you can see, there is no (easy) way to hardcode a path for the buggles that will lead to the solution.
It is very often the case in PLM that several worlds are used to have more than one test case for the code provided by the user. They act as separate unit tests for the proposed solution. The same code is run by every buggles in every worlds (some exercises have multiple buggles on the same world, too). In this case, you could still determine which is buggle is running by looking at the local configuration (where the walls are), and then hardcode a solution for each of them. So the exercise is not as robust as one could hope, but I'm not sure that it is worth fixing it. The maze lesson is just for fun anyway, the pedagogical value is not very high. A better fix would be to: - Change the error message to hint about the possibility that it occured in another world than the one currently displayed - Make the combobox blink in red for the same effect I think I prefer the first solution, because I'd like to change the PLM interface to move toward JavaFX so I prefer to not invest too much time to fix that swing interface. Do you confirm my analysis and validate my proposed fix?
