Could someone help me in understanding how to access Pico-8 sounds programmatically? I'm very interested in building a little synth and sequencer but am unsure of where to start. Especially when it comes to editing the amp envelope (ADSR) through code.

Any help would be appreciated! Thanks :]

Just messing around with flight mechanics

It is possible to orbit stars and planets. The general movement is a bit on the fast side compared to other space flyers out here.

For now there is only flying around and crashing.
I want to turn this into a proper game some day, but feel like the flight mechanics need to be sorted out first.
I made it a challange to figure out how to make the movement work by myself, so the math probably isn't that great yet.

Any feedback is appreciated.
I will add a better title eventually.

This is the first technicly winnable version.

Hey, go fishing for a while. Pick one of these six characters and try fishing for a little bit. It's easy. It's nice. Try fishing out for size. Maybe see if you can make it a whole week without losing your worms? No pressure though; just enjoy fishing.

Better physics, better learning curve, better music, better art, what can I say?

Alright, here's my first foray into an actual game.

Updates in v0.2:

  • Spiffy new title screen, makes start of game and game over states more pleasant

  • Significantly better control handling using a button input queuing system

  • Sound improvements, including Crash sound volume reduced

  • Brief start of game animation to help gently draw player attention to the snake before it begins to rocket across the screen

  • Win condition is less seizure inducing (though still too hard for me to reach legitimately so that I cannot easily confirm it even works right. Are there tool-assisted-speedrun uh.. tools for PICO-8 by any chance? 😅)

itch.io link if you want to look at it. With a trailer!

Hey!!!!!! I made a shmup, with Lazy Dev's Basic Shmup Tutorial. It's like a shmup, but it's not! A fun-filled, action-packed game, for the whole family to enjoy! (Except it's single-player but lets move on.)

Power-ups, bosses and explosions GALORE!!!! What's not to love?

There's even a ranking system included, free of charge, no need to thank me.

Now the real question: Are you ready? Are you prepared? We know you aren't, but you never will.

Self-indulgent game for me, very fun that other folks are enjoying it too. I really wanted to make something like Blocksum, where you were on the clock to make a kind of... big blob of high scoring stuff? I guess. THat's a game. Seeing Tetrachroma helped me figure out some stuff too. Ok!

I couldn't even get done with Rat Dreams before I started doodling stuff that turned into Kuiper Cargo... went through a few iterations before settling on this kind of level limit / upgrades approach. Really happy with pretty much everything tbh. Ok!

I am trying to run Pico-8 on Raspberry Pi 4b with pi os lite.
I have tried following this post: https://www.lexaloffle.com/bbs/?tid=140366
but it did not work for me.

when I tried this command, it just got stucked and nothing happened.
root@rpi0:/home/rpi/pico-8# ./pico8_64

for other executable pico8, pico8_dyn, I got this error:
root@rpi0:/home/rpi/pico-8# ./pico8_dyn
-bash: ./pico8_dyn: cannot execute: required file not found

can anyone guide me how to debug this problem?

Please include the ability to specify a png to render around the content area (perhaps a command line option, with a default file called bezel.png located in the pico 8 home dir). This would be super helpful for custom RasPi setups and also nice in MacOS and Windows.

Thanks!

A demake of the classic flash game Boomshine by Danny Miller. Clear the screen of balls by causing exploding chain reactions. If the song gets too repetitive for you, there is an alternative song that fits into the background better in the game menu. Or turn off the music all together and just listen to the song that emerges naturally which will probably be better than anything I could write. Let me know if the difficulty or mechanics needs tweaking.
