Let's start adding the code to create the blocks.

  • Go to and drag out Rectangle. Drop it on the line right after the random number.
  • Make sure that there is a green block ···· to the left of your rectangle code.

This is how the program knows which lines of code are inside the interval event.

To navigate the page using the TAB key, first press ESC to exit the code editor.

stage.set_background("city") sprite = codesters.Sprite("bike") 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(): # add any other actions... top_height = random.randint(1,10) stage.event_interval(interval, 2)
