| === Strategy ===
| |
| | |
| The default strategy is simple: choose a random direction and go there if the dot is open.
| |
| <pre>
| |
| def _turtle_strategy(self, turtle):
| |
| c = turtle[1] % 2
| |
| n = int(uniform(0, 6))
| |
| for i in range(6):
| |
| col = turtle[0] + CIRCLE[c][(i + n) % 6][0]
| |
| row = turtle[1] + CIRCLE[c][(i + n) % 6][1]
| |
| if not self._dots[self._grid_to_dot((col, row))].type:
| |
| return [col, row]
| |
| return turtle
| |
| </pre>
| |
| | |
| In this version, the turtle will go off the edge if it can.
| |
| <pre>
| |
| def _turtle_strategy(self, turtle):
| |
| c = turtle[1] % 2
| |
| for i in range(6):
| |
| col = turtle[0] + CIRCLE[c][i][0]
| |
| row = turtle[1] + CIRCLE[c][i][1]
| |
| if self._dots[self._grid_to_dot((col, row))].type is None:
| |
| return [col, row]
| |
| | |
| n = int(uniform(0, 6))
| |
| for i in range(6):
| |
| col = turtle[0] + CIRCLE[c][(i + n) % 6][0]
| |
| row = turtle[1] + CIRCLE[c][(i + n) % 6][1]
| |
| if not self._dots[self._grid_to_dot((col, row))].type:
| |
| return [col, row]
| |
| return turtle
| |
| </pre>
| |
| | |
| The dots are stored in a 13x13 array. Each dot has an attribute, 'type', that determines it status. The edges have a type=None. Occupied dots have a type=True. Unoccupied dots have a type=False.
