Cool, we have a bird. Next step: make it move!
You’re in competition with the teammate working on Myrtle. They may or may not have already completed the move_forward() function.
Add the following to MoveObject.py:
# MoveObject.py
def move_forward(self):
##
self.forward(CELL_WIDTH)
##
pass
And then add the following to Characters.py:
# Characters.py
class RobotBird(CustomTurtle):
def __init__(self, colour, shape, speed, game, start_position):
super().__init__(colour, shape, speed, game, False, start_position)
##
# YOUR CODE HERE
##
def move(self):
##
num_steps = random.randint(1, 5)
for step in range(num_steps):
self.move_forward()
##
pass
Finally, call the function that will actually trigger the movement in the bird.
Add the following to Game.py:
# Game.py
turtle.listen()
game = Game()
game.create_base_world()
game.draw_world()
##
game.create_user_turtle((0, 0))
game.create_robot_bird()
+game.bird.move()
##
turtle.mainloop()
Everytime you start the game the bird should move a random number of steps. Try restarting the game a few times to see this in action.
But we want the turtle to keep moving right?
Add the following to Game.py:
# Game.py
turtle.listen()
game = Game()
game.create_base_world()
game.draw_world()
##
game.create_user_turtle((0, 0))
game.create_robot_bird()
-game.bird.move()
+while True:
+ game.bird.move()
##
turtle.mainloop()
Restart the game, the bird should keep moving….too far, did it just fly off the screen? Don’t worry, we’ll fix that in a later step.
