Time to create the bottom block. We'll start by creating a variable for the height.
- Click on the PYTHON tab. Go to and drag Integer Variable inside the interval() event.
- Change the name of the variable (the word before the = sign) to bot_height.
- Change the value (after the = sign) to 350 - top_height.
Now we will always have a gap of 350 pixels to move the bike through.
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(50, 300)
# sprite = codesters.Rectangle(x, y, width, height, "color")
top_block = codesters.Rectangle(0, 0, 100, top_height, "blue")
top_block.set_gravity_off()
top_block.set_top(250)
stage.event_interval(interval, 2)
