Flappy bird for nibble

This is the code for flappy bird for the nibble! I used the code for the bit and modified it! Also, I have a suggestion, circuitmess. I think you should add the “push screen” block for the nibble like the bit has. It would improve the annoying screen flickering and make coding a whole lot easier.

from Nibble import *
import random
import time

sprite_bird = bytearray(b'\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\xFF\xFF\xFF\xFF\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\xAD\x55\xFF\xFF\xFF\xFF\x00\x00\xFF\xFF\x00\x00\x40\x00\x40\x00\x40\x00\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\xAD\x55\xFF\xFF\xFF\xFF\x00\x00\xFF\xFF\x00\x00\x40\x00\x40\x00\x40\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\xAD\x55\xFF\xFF\xFF\xFF\xFF\xFF\x00\x00\x40\x00\x40\x00\x00\x00\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF\xFF\x00\x00\xFF\xA0\xFF\xA0\xFF\xA0\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x40\x00\x00\x00\xAD\x55\xFF\xFF\xFF\xFF\xFF\xFF\xAD\x55\x00\x00\xFF\xA0\xFF\xA0\x00\x00\xC9\x86\xC9\x86\xC9\x86\xC9\x86\xC9\x86\xC9\x86\x00\x00\x40\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xAD\x20\xAD\x20\x00\x00\xC9\x86\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x40\x00\x40\x00\x40\x00\x00\x00\xAD\x20\xAD\x20\xAD\x20\xAD\x20\xAD\x20\xAD\x20\x00\x00\xC9\x86\xC9\x86\xC9\x86\xC9\x86\xC9\x86\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\x00\x00\xAD\x20\xAD\x20\xAD\x20\xAD\x20\xAD\x20\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00\x40\x00')

Hey @TestTubeGuy9999 ,

thank you for sharing your code, and for your feedback! :smile:

Best,

Would you guys be able to do it anytime soon?

Hey @TestTubeGuy9999,

unfortunately, as we stated in the previous post, this is a hardware limitation.

The ESP8266 microcontroller, which you can find on Nibble, doesn’t have enough RAM to use a display buffer when pushing the image to the display (when you have the Micropython installed, as the Python interpreter uses a lot of memory). The image is pushed onto the display directly, which causes that flicker.

This isn’t an issue with the stock firmware, as the memory isn’t limited by the Python interpreter in that case.

You can find out more about the display buffer here: Framebuffer - Wikipedia

Best,
Sandi
