=== 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.
