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.
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)
