Unoccupied dots have a type=False. − − Your strategy should start with: − − def _turtle_strategy(self, turtle): − − The turtle argument is a tuple containing the column and row of the current turtle position. That is, turtle[0] is the horizontal position and turtle[1] is the vertical position. − − Your strategy should return a tuple containing the column and row of the new turtle position, e.g., − − return [col, row] − − There are some resources that you can use in your program, including: − − ;CIRCLE: a 2x6x2 array of offsets that can used to find the col and row of the dots surrounding the turtle. − ;self._dots: the array of dots. − ;self._pressed: the index of the most recent dot pressed by the user − ;self._orientation:you can set the orientation of your turtle by assigning a number from 0-5 (clockwise beginning with 30 degrees from north) − ;self._set_label('your message here'):you can write a message on the toolbar if you want to communicate what your turtle is thinking − − === Where to get Turtle in a Pond === − − The Turtle in a Pond activity is available for download from the [http://activities.sugarlabs.org Sugar activity portal]: [http://activities.sugarlabs.org/en-US/sugar/addon/4516 Turtle in a Pond] − − The source code is available on [http://git.sugarlabs.org/turtlepond the Sugar Labs Gitorious server]. − − [[Category:Activity]]
