Karel Language Reference
Primitives
- void step() - Move Karel one intersection forward.
- void turn_left() - Pivots Karel 90 degrees left.
- void pick_beeper() - Take a beeper from the current intersection and put it in the beeper bag.
- void put_beeper() - Take a beeper from the beeper bag and put it at the current intersection.
- void turn_on() - Turn Karel on.
- void turn_off() - Turn Karel off.
Sensors
- bool front_is_clear() - true if there is no wall directly in front of Karel, false if there is.
- bool beepers_present() - true if Karel is standing at an intersection that has a beeper, false otherwise.
- bool facing_north() - true if Karel is facing north, false otherwise.
- bool beepers_in_bag() - true if there is at least one beeper in Karel's beeper bag, false if the beeper bag is empty.
Misc
- void set_step_delay(int) - Sets delay of one Karel's step in miliseconds.
Super Karel Language Reference

- bool left_is_blocked() - true if there is a wall immediately to Karel's left, false otherwise.
- bool right_is_clear() - true if there is no wall immediately to Karel's right, false if there is.
- bool right_is_blocked() - true if there is a wall immediately to Karel's right, false otherwise.
- bool no_beepers_present() - true if there is not beeper at the current intersection, false if there is a beeper at the current intersection.
- bool not_facing_north() - true if Karel is not facing north, false if he is facing north.
- bool facing_south() - true if Karel is facing south, false otherwise.
- bool not_facing_south() - true if Karel is not facing south, false if he is facing south.
- bool facing_east() - true if Karel is facing east, false otherwise.
- bool not_facing_east() - true if Karel is not facing east, false if he is facing east.
- bool facing_west() - true if Karel is facing west, false otherwise.
- bool not_facing_west() - true if Karel is not facing west, false if he is facing west.
- bool no_beepers_in_bag() - true if Karel's beeper bag is empty, false if there is at least one beeper in the beeper bag.
