Now we have to make the stars disappear when the Hedgehog touches them.

  • Go to and drag Collision to the bottom of your program.
  • Delete the .go_to() command from the collision event.

stage.set_background("moon") sprite = codesters.Sprite("hedgehog") sprite.go_to(0, -210) def left(): sprite.turn_left(20) stage.event_left_key(left) def right(): sprite.turn_right(20) stage.event_right_key(right) def up(): sprite.move_forward(575) stage.wait(0.1) sprite.go_to(0, -210) stage.event_up_key(up) def interval(): rand_x = random.randint(-250, 250) rand_y = random.randint(-100, 250) goal_star = codesters.Star(rand_x, rand_y, 5, 15, "yellow") # add any other actions... stage.event_interval(interval, 2)
