In this arcade-style game, you need to collect all the items (blue circles) and avoid the enemies (red circles) in a circular stage to move to the next one. To do this, you need to move not only from left to right, but also dashing from one side of the stage to the other, which can be done with the O Button/Z Key. Try to clear as many stages as you can!


Controls:

  • Left/Right - Move
  • O Button/Z Key - Dash/Start

Thanks to the PICO-8 Discord server for all of the help and feedback!

Hey, how do I actually start this? I have PAID for the Pico-8 but I cannot see any obvious way to begin. Help anyone?

Final jam submission is here on the bbs! The "office" tutorial should hopefully teach how the game works, and address some of the problems people have been having figuring out the game. I've had very little time to playtest it (being a jam and all) so if anything still isn't clear or if you don't like something I'd like to hear your criticism!

Rare Monster Truck

A monster truck game with an ordinary name

This one is mostly aimed for kids and mostly designed and named by a 5 year old, meaning low on challenge but still enough for a bit of fun. Plus who doesn't like monster trucks.

Like my ghost game, the truck IP is totally original. Any similarities with real life trucks is purely co-incidence.

Now start your engines and get to crushing.

(i'm just now realizing how incredibly counter intuitive is to use stop and continue on the same button)

Ship captain crew is a dice game, I learned at a bar.

It can be a drinking game, but I've never played it that way (though I have always been drinking when I played it) I only know it as a basic very short gambling dice game.

The rules are pretty simple. But kinda hard to explain.

you are trying to get a 6(the ship) a 5 (the captain) and a 4 (the crew).

You roll all five dice, if you get a six you take it out and set it aside, same for five and four. Eventually you'll only have 2 dice left. These are your score (sometimes called cargo) you want the highest score.

The catch is that you have to get 6,5,4 in order.

For example if your first roll is 5,5,4,3,2 you get nothing. You must re-roll all dice. You cannot have a captain or a crew without a ship.
You re-roll and you get 6,4,4,3,3. You take the six and set it aside. You can't take one of the fours. You can't have a crew without a captain.
your final roll! 5,4,3,5. You take a five and set it aside then the four. You have eight points.

You could also get lucky, and on your first roll get 6,6,6,5,4 and suddenly have 12 points and stop right there.

  • the current highest score is called the point number.

  • Always keep rolling until you at least tie the point number.

  • You cannot re-roll only one of your final 2 dice. (its easier to code, but it's also the rules, at least at my local bar that plays it)

  • In case of tie no one wins. The money stays in the pot, everyone who wants a chance at it pony's up another buck and you go again.

This game should follow the rules as I understand them. They might be regional, I've seen others online claim that in case of tie the people who are tied play against each other, but I like the "let it ride" approach. I've seen a game of roughly 10 people end up with about 50 dollars in the pot due to consecutive ties.

Also the winner starting the next round might be regional, i've seen online people saying it rotates, but starting is actually a disadvantage (it's better to go later) so I think it makes sense for the winner to start.

I might change the rolls to display how many rolls you have left. I'm not sure that'd be better.

I hope to add some weird role playing elements like a luck score that will make dice rolls work out better for you, and also make the CPU players behave differently and have their own luck scores.

Also I want a nice random-ey looking dice rolling animation

A few things that would make this better:

  • More optimization
  • Higher resolution (if possible)
  • monotonic cubic interpolation for advection (likely too expensive)
  • MAC grid (NOPE - saves a lot of time to backtrace all quantities from cell centers instead. A MAC grid would mitigate some of the boundary artifacts here, but it's just too slow.)
  • vorticity confinement (expensive, but probably the next most important thing)
  • better smoke vis - bilinear interpolation? (almost certainly too expensive)
  • higher resolution for smoke than for velocity?
  • other forces: gravity / heat / etc.

Littleroot Town theme in PICO-8
It kinda sucks right now so I might keep working on it to make it more like the original

Pico Tower

Office Tower Simulator

Cart #tomuhikipi-3 | 2022-01-11 | Code ▽ | Embed ▽ | No License

What is this

Pico Tower is a tower simulator in the vein of a scaled-down SimTower or Project Highrise.
Build offices and provide needed services to earn money. Grow your tower and unlock more features as your tower grows in height. Experiment with layouts to optimize travel times for your tower's occupants.

Tips

  • Most rooms have an entranceway indicated by a yellow doorway. When building make sure this side is rotated to be accessible.
  • If a meeple is travelling, they aren't making money! Optimize travel times to make sure offices stay profitable.
  • If a meeple cannot find a nearby service they will eventually leave the building to meet their need elsewhere.

TL;DR

Run load #prof in your local PICO-8 console, then edit the last tab with some code you want to measure:

prof{
  locals={9},         -- args to pass each function (optional)
  function(x)
    local _=sqrt(x)   -- code snippet 1
  end,
  function(x)
    local _=x^0.5     -- code snippet 2
  end,
}

Run the cart: it will tell you exactly how many cycles it takes to run each code snippet.


OVERVIEW

This tool measures precisely how many cycles it takes to run arbitrary snippets of code. I use it all the time when I'm trying to figure out the fastest way to write an algorithm. For example, it's massively helpful to know the fastest way to calculate abs(x) in a modular synthesizer that needs to run this operation tens of thousands of times per second.

For context, PICO-8 runs at 8 million cycles per second. This number is unimaginably large and yet also hundreds of times slower than most desktop computers. To keep things in perspective, I like to remember that 1400 cycles is equal to 1% of your CPU budget each frame (at 60 fps -- 8*1024*1024/60/100 = 1398.1)

One post, two topics -- but I figured they are mildly related here since it's really up to zep in both cases :D

I know it's a long shot, but is there any chance of getting a port of PICO-8 to MIPS? Specifically, I want to be able to use my Abernic RG280V to play PICO-8 games on the Adam image (https://www.youtube.com/watch?v=kdIdiQ-dO_Y).

Second topic. Is official Apple Silicon (aka ARM64) support on the roadmap for the Mac version? I know the Intel version runs just fine under Rosetta, but there is still downsides to running Intel code on these machines, like additional memory and battery usage. Plus it future proofs things a little for the eventual (still years away) removal of Rosetta by Apple in a future OS update.

Second work in progress release based on user feedback.

Score, style meter, deathscreen with results and office practice room added.
Killfloor rises much slower, rising faster based on your level
Filling boost is made consistent, takes about 5 kills (fountains count as half)

Style rank adds power to your boost! The higher your rank the higher you fly!

[[z,x, and arrow keys to control
double jump recharges with time
double tap and hold direction to stinger attack
You can walljump (though not for much height)
hold up or hold down to do different attacks. Up attacking a stunned enemy gives you height!
Hold x while doing down attack to keep it active. Doing this on a stunned enemy stops this from canceling.

TO LOAD THIS CART in immediate mode, type: load #to_infinity

Written using 5 Pico-8 commands, see code.

Back when i was writing S2 (scenario rpgmaker 2), I wanted to have that cool neat zoom effect like you get on the SNES and more modern RPGs when you enter combat, you know, where the screen would blur and rotate and zoom forward.

At the time I was working in GFA for windows 3.1 and was told it could not be done, that it would require me to grab every pixel on the screen, calculate their point outward, then redraw them.

And yeah the first time I attempted that it was terribly slow and not even that pretty.

c-base - drink all the mate

my very first and very simple club-mate drinking game :D

footage

story

you are a nerd that needs all the club-mate they can get
every step drains your energy but club-mate can refill it
when you finished all the bottles you win
if you have no energy left and also no mate you loose

controls

you start the game with X

just walk over the club-mate bottles to drink them
and replenish your energy

why?

i just wanted to draw the c-base hackerspace logo in pico-8.
then i thought, ok what game could i write?
so i thought of c-base and whats there a lot. It's nerds and mate.
so story found, you are a nerd in a nice dark hoodie on the search for
all the club-mate in c-base.
