Hello, I have a use case for some external tooling interacting with a running game. While the game is running I'd like it to process messages sent to it by the tooling. Currently it's not possible to do non-blocking reads from stdin. Calls to serial(0x804, ...) will block until the pico 8 process receives something. What I'd like to do is something like this:
function _update()
-- Hypothetically stat returns true if there's data available on stdin, false otherwise,
if stat(123) then
serial(0x804, 0x4300, 1)
local message_type = peek(0x4300, 1)
process_message(message_type)
end
end |
It would be useful to have some way to tell if there's data available on stdin or to perform non-blocking reads from stdin.

Durnshire Crossing
A Frogger remake
My very first full game on Pico-8! It's a simple fantasy-themed Frogger-like game, with goblins and orcs and stuff. Very simple, just use arrow keys to move around and avoid the monsters along the way. Cross the river with the barrels and boats and grab all coins to get to the next level! Advance far enough and battle the guardian dragon!
Hope you enjoy!

Controls
Move card: ⬆️ ⬅️ ⬇️ ➡️ keys
Rotate card: tap "Z" key
Place card: hold "Z" key + tap ⬇️ key
Help screen: hold "X" key
Rules
The aim of the game is to grow trees in your orchard by placing cards. The more trees you have, and the older the trees are, the more points you will score. 🌳
You can only place cards when at least one of its fruit types (apple/lemon/blueberry) overlaps an existing fruit type in the orchard. Once a card is placed, any matching fruit types underneath the card will grow.

Abandoned: a celeste classic mod
This mod adds 3 new mechanics, a completely new set of levels, and even a 100% original not-so-secret route that's definitely fun i promise.
The difficulty of this mod is above normal celeste difficulty, so I would recommend playing the base game if you haven't already
Controls:
jump: z/c
move: arrow keys
dash: x
v4 update: made one level more speedrun friendly and fixed the dashing after using cannon bug
If you get stuck feel free to ping me @coolelectronics on the celeste classic discord server.

so I tried to use my Playstation 5 controller with my PICO-8 software, it is running on windows and I added the sdl2 map. Here is the map:
030000004c050000e60c000000000000,PS5 Controller,a:b1,b:b2,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b12,leftshoulder:b4,leftstick:b10,lefttrigger:a3,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b11,righttrigger:a4,rightx:a2,righty:a5,start:b9,touchpad:b13,x:b0,y:b3,platform:Windows,
it should be correct yet when I try to use my Playstation 5 controller it isn't working, no buttons do anything. I read the wiki on how to set it up and I think I'm doing everything right. what are common mistakes or causes that this doesn't work.

Based on a request for help in the Pico-8 Discord, I ended up working on a rope/string/ribbon/chain/etc. simulation:
The behavior of the rope changes substantially depending on the gravity and drag settings.
This sim tries to model the object as inelastically as possible, although it's far from perfect in that regard. The rope here has 128 segments, which is very difficult to handle without (a) instability, (b) excess springiness in the rope, or (c) tons of damping. So i ended up having to write a slightly clever constraint solver (multigrid for n log n instead of n^2 performance), and I chose a step schedule that uses almost 100% CPU at 60fps. But if you use fewer segments and tune the solver differently, going down to 16 segments or so and using a less conservative step schedule, like one suggested in the cart comments, you can get the CPU usage closer to 5% at 60fps. That might be more suitable for inclusion in a game.
