I don’t get this, where are the following functions defined?:
frontIsClear() – probably boolean
facingEast() – probably boolean
facingWest() – probably boolean
turnLeft() – probably void
frontIsBlocked() – probably boolean
move() – probably void
turnRight() – probably void
noBeepersPresent – probably boolean
turnAround() – probably void
etc.?
Or are them in the libraries stanford.karel.*?
(which I cannot find)
