[BUG] Better error message for 'backward' #1937

Open MarleenGilsing opened 2 years ago

MarleenGilsing commented 2 years ago

At the moment Hedy gives the 'you forgot to use a command' error when using backward in the turtle. While I think that would be a very logical command for a student to try. So maybe create an error message that tells you backward isn't a command but you can use forward and negative numbers.

Would a custom error message for the first level be desired?

MarleenGilsing commented 2 years ago

@huang-v Yes it is, thanks! I would like the error message to make clear that the turtle can go backwards but they have to use forward -100.

Yeah we have this nice string distance error for other keywords, maybe we want to use that here too?
