STEP 18: Now let's create the asteroid sprites that will run across the bottom of the screen!

  • Click on GRAPHICS. Go to and drag Sprite At Position inside the interval() event.
  • Change the name of the sprite to bot_rock. Change the image label to "asteroid".
  • Click on . Drag Set Height inside your interval event, under your bot_rock sprite.
  • Change the name in front to bot_rock. Change the number in parentheses to the variable bot_height.

stage.set_background("space") sprite = codesters.Sprite("spaceship") sprite.set_size(0.5) sprite.go_to(-200, 0) stage.set_gravity(10) stage.disable_all_walls() def space_bar(): sprite.jump(5) # add other actions... stage.event_key("space", space_bar) def interval(): top_height = random.randint(50, 300) # sprite = codesters.Sprite("image", x, y) top_rock = codesters.Sprite("asteroid", 0, 0) top_rock.set_height(top_height) top_rock.set_gravity_off() top_rock.set_y_speed(0) top_rock.set_top(250) bot_height = 350 - top_height # add any other actions... stage.event_interval(interval, 2)
