CallumAlder | 42:121148278dae | 5 | MAXCMDLENGTH |
CallumAlder | 42:121148278dae | 6 | move the global variables to a class because we arent paeasents - Mission Failed |
CallumAlder | 42:121148278dae | 7 | use jack's motor motor position |
CallumAlder | 42:121148278dae | 8 | fix class variable naming |
CallumAlder | 42:121148278dae | 9 | dont make everything public becuase thats fucling dumb and defeats the whole point of a class |
