Re: Debugging a Robot

I managed to fix it, I had copied one of my formulas for the tracking wrong, so a NaN had probably come into most of the calculations. I put a purposeful runtime error, and can see that they do indeed get put into the player console.

Your second point is interesting, becuase I am currently using an AdvancedRobot but don't call execute(). It might be because I am still using, for example, ahead instead of setAhead and turnRightRadians instead of setTurnRightRadians.

I am pretty sure that this is because of a runtime error in the javavm, but I don't know how I can see the error output. How would I go about debugging the robot and seeing the runtime error? I'm pretty sure the error comes from a division by zero somewhere, but I would really like to know the line it occurs on.
