In my game Orbital there's a circ() call that looks like this:
circ(ax,ay,(time()*400)%4800,3)

It represents a rapid expansion (approx 13.3 pixels in radius per frame) of a circle until it reaches a max radius of 4800, then it restarts.

It looks like this up close (it's the fast green one at the end):

and it should be able to be seen from 37.5 screens (4800 pixels) away. (The mini-map at the top represents 16 screens width):

However, when playing on the web version, the circle only extends to 1024 pixels radius, then it stops rendering until it cycles around again. It never renders the circle with a radius bigger than 1024. Not sure why this is, but it happens on the Pico-8 BBS and on Itch.io.

edit: limit appears to be 1024 on Firefox 99.0, actually a little bit less ~980 on Safari 12.1.2

Poop Collector

The world is overflowing with POOP! You are summoned to help and collect it all!

This game has 32 levels, each one has a countdown of only few seconds to clear and collect all of the scat laying around. A simple platformer made with PICO8 where all you need to do is move left and right and jump from the start point to the exit door after everything is collected.

This game has 3 difficulties:

  • Easy
    • Start with 5 lives
    • Each level has extra 4 seconds
    • When resetting a level you don't loose a life
  • Normal
    • Start with 5 lives
    • No change in base time for levels
    • When you reset the level you lose 1 life
  • Hard
    • Starts with 1 life
    • Reduces each level's timer that is over 5 seconds by 2 seconds (or by 1 second if the level starts at 6 seconds)

When you reset the level you lose 1 life
Have fun, this is my first project in PICO8 and in general probably my second or third game that can actually be played from start to finish.

Thanks for playing!

Feedback is welcome!

Because of a serious bug, and for speedrunning reasons, below is an earlier version of the game that had hyper dashing, allowing for some crazy speedruns.

This isn't a celeste mod! (even if it would have been easier to make a celeste mod...)
I programmed and made everything my self, which explains why this is pretty much an inferior version of celeste.

Farland v2 as the name implies is a sequel to my first ever mod Farland. This mod is primarily a map mod like the original although there's some new mechanics, music (thanks RubyRed), etc. If you haven't played the original Celeste classic before playing this than I highly recommend it as some of the later levels may prove to be very challenging without previous experience.

Controls:
Arrow keys - Movement
Z/C - Jump
X - Dash

Huge thanks again to RubyRed for making the entire OST of the mod, and i want to give thanks to Maddy thorson and Noel berry for the original

PICO-8 0.2.4c is now up on lexaloffle, Humble, itch.io, and for PocketCHIP.

This is mostly a bug-fixing update; you can see the main 0.2.4 change notes in the 0.2.4 thread.

URL Cartridges

With the release of PICO-8 Education Edition, it is now possible to encode cartridges into a 2040-character URL that runs it in a web version of PICO-8's editing tools. Only the code and graphics sections are stored.

> SAVE @URL
COPIED URL TO CLIPBOARD
265 / 2040 CHARS

Tiny Cartridges

When exporting cartridges to .p8.rom format (the raw 32k block of data that is encoded inside .p8.png argb data), 0.2.4c allows only the code section to be stored using the -t (for tiny) switch:

> EXPORT -T TINY.P8.ROM
WRITING 154 BYTES (CODE ONLY)

You should get a file that is exactly as large as the compressed code size reported by INFO. When using LOAD, that file will be loaded into the code section, and the other sections reset to their default states.

There isn't much practical use for tiny .P8.ROM files, but I think it is nice to be able to store a tiny program in its true tiny form on disk.

On the subject of tiny cartridges, for those making

On a particular Linux system I was recently using wget was not installed by default. Splores in game message was "could not connect to bbs" which led me down a rabbit hole of network checks until I noticed the wget missing error in the terminal. I was running via a pico8.desktop entry without the terminal originally.

Could curl be used as a fallback? Running "curl -L -O" can usually be used as a fallback in many cases. Better yet just use libcurl in the compiled binary and then you don't need wget or any external tools.

Thanks!

@zep

Hey! Remember when I suggested putting next in the globals, since we could get to it anyway by doing next=pairs{}? You did! And that's been great!

Would it be okay to get inext the same way? It seems to be present, since I can get it by (similarly) doing inext=ipairs{}, and it seems to work the same way, just limited to index,value instead of key,value.

It's just not officially exposed.

I'm asking because there's a token saved when you switch from the first to the second implementation here:

for k,v in pairs(t) do ... end
for i,v in ipairs(t) do ... end

-- these are a little less clear to the reader but they work the same and save a token
for k,v in next,t do ... end
for i,v in inext,t do ... end

Technically it also shaves a couple of cycles off of the loop setup by inlining the return tuple from pairs()/ipairs(), but it's really the token savings that would be handy in some cases.
