Flappy bird Micro:bit python tutorial for beginners

Step 1: Display welcome message

It’s really hard to play flappy bird if the game starts straight away: it works better if you give the user some warning that the game is about to start.

  • Add a line to your code that scrolls the text “Get ready…” across the screen:
from microbit import *

display.scroll("Get ready...")

Extend it with code

If you think the text scrolls too quickly or slowly you can change the speed using an additional parameter to the scroll procedure:

display.scroll("Get ready...", delay=200)  will scroll the speed twice as fast and  display.scroll("Get ready...", delay=800) will scroll twice as slowly.

Feel free to change the “Get ready…” message to whatever you like, but don’t forget the double quotation marks or brackets either side.

      Hi Darryl,

      Thanks – you’re right – sorry about that. I made a mistake when making micro:bit python simulator for the Image.shift_left() function – it ignored the parameter, which your comment has helped me fix: cheers!

      I’ve changed line 71 from i = i.shift_left() to i = i.shift_left(1) which should fix the problem when you test it on a micro:bit.

      Thanks for getting in touch, sorry about the error. Please could you post a link to your code or let me know which example you’re getting the error with?

        I’ve got the code https://create.withcode.uk/python/58B

        It is at the section of
        def make_pipe():
        i = Image("00003:00003:00003:00003:00003")
        gap = random.randint(0,3)
        i.set_pixel(4, gap, 0)
        i.set_pixel(4, gap+1, 0)
        return i

        The micro bit shows 'name error' ' name not defined'
        Hope this helps
        Thanks

    I’ve edited your comment to replace the code with a link if that’s ok? – posting python directly on here gets rid of indentation and swaps some characters like quotation marks. I can’t seem to get the same error as you on the simulator or a micro:bit. Please could you check the link and see if it works for you or if the code matches yours?

      I’ve tested the code you post on micro bit and it seems like it’s still having the same error message.
      Line 17 ‘name error’ name ‘random’ is not defined.

      Sorry my misunderstanding with your comment, i thought you fixed the issue. Yes the code matches my original code that I’ve got.

    Sorry-that’s very frustrating. It runs on a microbit without an error for me. Are you getting the hex file from create.withcode.uk when you run the simulator or are you using a different editor? Could you try clearing your browser cache in case you’ve got an old version of the runtime stored. You’re the second person to say there’s a problem with the random module so I’d like to track down what the issue is, but I can’t replicate the problem on any browser. Thanks for your patience and help.

      Hi, I tried clearing the cache and the same error occurs again. I’m using https://python.microbit.org/v/1 to edit my coding. Normally I would save the file from as a .py file and drag the file into the Micro:Bit folder.

      Hope those information helps

        Thanks – that’s helpful.

        The micro:bit can’t run .py files directly: micro:bits need to be flashed with .hex files which contain both your python code and the micropython runtime which tell the micro:bit how to interpret your code. In the https://python.microbit.org/v/1 editor you’re using, you need to press the download button to create a hex file. That’s the one you then drag into the micro:bit folder. In create.withcode.uk, press ctrl + enter to run your code and you’ll see a link above the simulator that will let you download the hex file.

        Hope that helps.
