To make things a little more interesting, we’ll add a new bird for each world. So the first world will have one bird, the second world will have two birds, and so on…
Add the following to Game.py:
# Game.py
def find_next_world(self):
##
if self.world == len(WORLDS) - 1:
self.game_end()
else:
self.clear_world()
user_turtle_start_position = self.current_world.portal_position
self.world = self.world + 1
self.current_world = WORLDS[self.world]
self.draw_world()
- self.create_robot_bird()
- self.bird.move()
+ num_birds = self.world + 1
+ for count in range(num_birds):
+ self.create_robot_bird()
+ for bird in self.birds:
+ bird.move()
self.create_user_turtle(user_turtle_start_position)
##
pass
We’ll need to check for collisions with all the birds.
Add the following to MoveObject.py:
# MoveObject.py
def is_collision(self):
##
- if self.game.myrtle.current_position == self.game.bird.current_position:
- return True
+ for bird in self.game.birds:
+ if self.game.myrtle.current_position == bird.current_position:
+ return True
return False
##
pass
Finally, make sure you remove the additional birds from testing earlier.
Remove the following from ‘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.create_robot_bird()
-game.create_robot_bird()
while True:
for bird in game.birds:
bird.move()
##
turtle.mainloop()
