Function getNewBoard

src/gamesbyexample/hungryrobots.py:62–92

Returns a dictionary that represents the board. The keys are (x, y) tuples of integer indexes for board positions, the values are WALL, EMPTY_SPACE, or DEAD_ROBOT. The dictionary also has the key 'teleports' for the number of teleports the player has left. The living robots are store
