A simple game on the RPI Pico

scottiebabe
scottiebabe over 2 years ago

Pimoroni have recently included support for basic 8x8 pixel sprites in micropython https://github.com/pimoroni/pimoroni-pico/tree/55821d2896ac12732c4e84142ba1fb76d4382dc5/micropython/modules/picographics#sprites 

So, I would like to try and make a simple holiday game on a RPI Pico.

I am thinking of something along the lines of:

image

Where the objective of the game is to avoid airborne objects while dropping presents into chimneys.

Two buttons for Rudolf up/down. Then a third button for santa to drop a present.

I got this Pimoroni example to run with my Pico Display: https://github.com/pimoroni/pimoroni-pico/blob/main/micropython/examples/tufty2040/awesome_game.py 

So, I can use that as a starting point. I'm still not sure how I will handle a scrolling scene.

I'll post a quick video of the example code running later.

Edit:

The 8-bit color gives such a cool retro vibe, I love it!

    What a cute idea! Maybe start with a static screen where Santa goes back and forth dropping presents into a static set of chimneys. The challenge element could be "smoke" coming out of the chimney means…

    You could perhaps drop baubles onto the Xmas trees causing them to light up/decorate. Brussel sprouts would make good airborne objects to avoid. Perhaps some carrots for the reindeer to collect and mince…

    irfanview You can select the target number of pixels, edit each pixel, select the color depth, select the file format, etc.

    Here is an image of the 2 sprite sheets I found at: https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/examples/tufty2040

    There are some here that might be morphable into usable sprites: https://www.shutterstock.com/search/christmas-sprite

    The page says "Christmas sprite royalty-free images" but on the other hand requires paid sign-up to see them without the junk overlays. So I think it's totally acceptable to clean up the preview images and not register, since the royalty-free bit was stated unequivocally and with no conditions.

    The clean-up would be needed get rid of the magnifiers on the top-right of the previews (or not use that frame) also they might not have proper spacing.

    This is wonderful! Thank you. I was also trying "https://icons8.com/" but am struggling to go from a high resosultion image to an 8x8 or 16x16 (I could draw 4 8x8 sprites as one)

    I have been playing with inkscape to make pixel art, perhaps its not the best:

    Any advise on how to scale images to an ultra small size ? :)

    Hi!

    If you've got a Linux box handy (or Pi):

    apt-get install imagemagick

    then:

    convert infilename.png -resize 32x32 outfilename.png

    I transparentized the reindeer

    https://1drv.ms/u/s!AlgR3ZgXGd0MqhPlNByvi_UVgZOA?e=C3zSzS

    Also got rid of the magnifier. Don't know if that helps or not,maybe there were different images you wanted?

    Anyway, if you need any transparentizing or basic removal of simple watermarks/junk, I'm quite good at that : ) Just send me the pics and I can figure that bit out.

    I'm not any good with artistic stuff though! : )
