My first try at making a genetic algorithm, I will use it as the base for other projects.
I recommend using the black and white filter in the accessibility settings, since the values are based on the darkness of the color, darker to clearer as values become larger.

stars

a parallax background thing

I was looking at a friend of mine's game and saw a cool star background effect. I decided I wanted to make something similar. I ended up with this. It's not quite the same, but still cool.

Opening the pause menu (enter or p) lets you configure options for it.

The mouse does not work on BBS carts, however it works fine in the app. Run load #stars_effect to use it.

thoughts?

This is my first PICO-8 cartridge.
There are still some problems, but I decided to complete it once for now.

This is a game in which you control a stickman to avoid spikes and birds.
Inspired by Chrome Dino.
BGM was borrowed from 般若's MIDIの里 and used with denote.

Jump to avoid spikes and avoid birds by sliding.

Controls

• Left&Right: Move
• Up/O: Jump
• Down: Sliding...?

Current issue

• There are times when the placement is absolutely unavoidable. (Serious problem)
• The placement of the spikes follows one pattern to some extent. (spike-->spike-->(spike)-->bird)

This is a pong clone I was working on over the winter break but had to stop on once my college semester started up. I just finished it and I hope you enjoy!!! Also, hats off to Lazy Devs for getting me into pico-8 development. As you keep the ball in play the balls horizontal speed will increase and its color and point value will change. It's the same objective as OG pong. First player to (or past) 15 wins the game. Hope you enjoy!

not a game, not interactive. just an animation. the header for this section claimed to appreciate curiosities :)

it's within a month or so of easter here in the united states, and being within a month of a holiday means retailers are all keen to sell varying confections with absurd sugar contents vaguely themed after the season. "peeps" are a hallmark of this time of year for a lot of people, as a result. they're little marshmallow sweets with what amounts to a pure sugar coating on them. they usually come in packs of 4 or 8, and are shaped like small animals, typically bunnies or chicks (baby chickens...). i don't think they're often widely distributed outside the united states and canada.

there's a recurring urban rumor i hear every year that claims that peeps have their little eyes burnt on with lasers at the factory after they're formed. sadly, this isn't true, but the rumor continues circulating nonetheless. i was talking about this with a friend, and decided to animate a little view into the hypothetical peep factory where the peeps are granted their faces.

Hi,

I'm currently working on my custom editor to edit tiles in one of my game, using reload and cstore functions from another cart. But there's something I don't know how to do. I want it to detect if the other cart is present when I launch the editor cart, and output an error message if it isn't. Can someone help me?

Thanks in advance

There seems to have been a change in the virtual cpu cost of +=

Previously, in 0.2.4b, both x=x+y and x+=y cost 1 cycles.
Now, in 0.2.5g, x=x+y costs 1 cycle while x+=y costs 2 cycles.
(Where x and y are locals)

The same happens with other operators that cost 1 cycle, e.g. -=/- and &=/&

This feels like a bug since I wouldn't except x+=y to be costlier than x=x+y

Below code shows the perf. difference.

function testme_calib(name, func, calibrate_func, ...)
  -- based on https://www.lexaloffle.com/bbs/?pid=60198#p
  local n = 1024

  -- calibrate
  flip()
  local unused -- i am not sure why this helps give better results, but it does, so.

  local x,t=stat(1),stat(2)
  for i=1,n do
    calibrate_func(...)
  end
  local y,u=stat(1),stat(2)

  -- measure
  for i=1,n do
    func(...)
  end
  local z,v=stat(1),stat(2)

  -- report
  local function c(t0,t1,t2) return(t0+t2-2*t1)*128/n*256/60*256*2 end -- *2 for 0.2.x

  local s=name.." :"
  local lc=c(x-t,y-u,z-v)
  if (lc != 0) s..=" lua="..lc
  local sc=c(t,u,v)
  if (sc != 0) s..=" sys="..sc

  printh(s)
  print(s)
end

function testme(name, func, ...)
  return testme_calib(name, func, function() end, ...)
end

testme("+", function(x,y) x=x+y end, 1, 2)
testme("+=", function(x,y) x+=y end, 1, 2)

Hey All!

In Release 1.7 I have immortalized winners from my recent caravan competition :) They will forever be in this game now!

Also I have fixed options movement in Level 20 and later, there was a bug causing options beyond 20 to be stuck to the middle of the screen ( they now move as they should along with the other dozens of options in virtual insanity... the way it should be )

I believe this will be the last update unless another bug is found. Thank you to SquidLight yet again for his guidance on tokenizing my code so I could fit in the caravan winners.

Time to take a short break from devving!

Hi! I am a little new to PICO-8 and I am trying to make a Flappy Bird clone as it is one of my all time favorite games. I am having trouble on just one thing, pipe rendering. I have the top and bottom pipes working, but when I try to put the other pipes going up and down to the screen, it screws up. Can anyone help me? (Sorry for no cartridge image)

Hi,

pico-8_0.2.5g_windows
This morning after startup eset32 marked and deleted pico8.exe as suspicious. It is probably an error on their side. I had it installed for some time and came out of the blue.
Should i report a false positive?

I saw some cartridges had large images that would take the whole space of the spritesheet. To prevent that, they use strings to store data.

The bugs:

Colours:

• Q: 0
• W: 1
• E: 2
• R: 3
• T: 4
• Y: 5
• U: 6
• I: 7
• O: 8
• P: 9
• A: 10
• S: 11
• D: 12
• F: 13
• G: 14
• H: 15

Special characters:

• J: New line
• K: Space
