How do I switch the roles of the background gray blocks with all the floor pieces? I am quite stuck and tried myself, it didn't work

This is a game I think I want to continue making.
You're a robot with a gun.
I'll leave out the story details for now..

Press X to shoot
Press O to interact with things (like doors)

Let me know what you think and if you have any cool ideas!

first game using pico8, just snake.
remember to like, comment, and subscribe.

Hello, I accidentally deleted my thread that had my main menu from a multi-cart game, and now my game doesn't function as intended. Is there any way to get the thread back?

i'm prepared for explanations that may contain math.
i have been working on this for too long over many attempts. it kinda works but there are definitely still issues.

i'm having problems with...

• normal calculations being off only some of the time
• when a shape returns to it's normal size, another the shape it collided with previously will get stuck inside
• shapes hovering 1 pixel over the ground???
• shapes are very bouncy
• shapes will not stay on other shapes (line segments can't collide with singular points)
• jiggle (i'll implement damping later on.)
• and cpu (not a priority yet, AABB tree later)

there are some comments that will hopefully help you find the issues in constrain() and shape_collision()

thanks

PicoTron file browser

I was looking through picotron's code, and i got a completely random idea!
"hey, LS and CD are really annoying..."
"..."
"okay screw it"

So yeah, this is a port of my pico-8 filebrowser "Picobrowser", but for picotron! it supports everything picobrowser did, but this can view and edit files! You can also edit it to detect more filetypes.

How to use:

Click "Show" button below and copypaste the code into picotron, then run!

cls()
function _init() --main init loop
  mode=0 --define vars
  p=1 
  e=0
  c=0
  dir=""
  dirt="/"
  odir={}
end

function _update() --main update loop
  flip()
  if dirt==nil then dirt="/" end
   if mode==0 then --check if mode=0
    flip()
    fil=ls(dirt.."/") --set fil to current dir path
    if fil==nil then end
    dir=fil[p+e] --set dir to current file+extention+location
    mode=1 --set mode to 1
    a=#fil --set a to fil table
    if a>24 then --check if total # of files is more then display size
      a=24
    end
  elseif mode==1 then --check if mode=1
    flip()
    cls(1) --clear screen to color 1
    for i=1+e,a+e do --for i=1+selected file, (incremented by total files+scroll amount)
      t=fil[i] --set t to index number of current file
        c=2
      if sub(t,-4)==".p64" then --check for carts
        c=14
      elseif sub(t,-4)==".txt" then --txt
        c=6

This is my first game in general, and the first time I try PICO8.
I am planning to make it more unique in the future, for now its basically snake.

PS: the text is in Portuguese for now

im tryin to make a platformer base to use for future projects, but when travelling in positive directions, the collision is seemingly not detected until a full pixel further than it should be

            local xd=n.x+n.speed.x+n.w/2*sgn(n.speed.x)
            local yd=n.y+n.speed.y+n.h/2*sgn(n.speed.y)

            n.grounded=false
            n.walled=false

            if fget(mget(xd\8,(n.y+n.h/2)\8))==1 or fget(mget(xd\8,(n.y-n.h/2)\8))==1 then
                n.x=xd\8*8+(n.speed.x>0 and -1-n.w/2 or 8+n.w/2)
                n.walled=true
                n.speed.x=0
            end

            if fget(mget((n.x+n.w\2)\8,yd\8))==1 or fget(mget((n.x-n.w\2)\8,yd\8))==1 then
                n.y=yd\8*8+(n.speed.y>0 and -1-n.h/2 or 8+n.h/2)
                n.grounded=true
                n.speed.y=0
            end

            n.x+=n.speed.x
            n.y+=n.speed.y

this happens at any speed/width/height combination, and the readings are from the last 5 frames before a collision is registered
i have a feeling this is because of flooring but i dont know how i would fix it :3

Hi all,

It was also important to me to have a matching "Dark Mode" variant, as that's my go-to style 🕶️

Dark Version

• 🔠 Clear, Monospaced JetBrains Mono Font
• 🔷 PICO-8 API up to v0.2.5g
• 🎨 Full PICO-8 Palette (inc. "Secret" cols)
• 🦓 Matching "Light" and "Dark" variants
• ⌨️ All Major PICO-8 Keyboard Shortcuts
• 🖌 FILLP() Mask + Glyph Patterns
• 🔄 Turn-Based Angle + Trigonometry Primer
• 🈂️ Full Character Set
• 😺 Glyph List + Constant Values
• 🐛 Debugging
• +More!

Please let me know what you think (...especially if you spot any errors! 😬)

Below you will find links to high-res .PNG + .PDF exports of my cheat sheets, enjoy! 🤓

Picoblazer 1K: A #pico-8 homage to the epic 1986 Trailblazer for Commodore 64, in 1017 bytes of compressed lua code. Produced for the 2023 #pico1k jam.

Use the left and arrow keys to direct the ball to the end of the track, while avoiding pits. Red tiles will bounce the ball back while green ones will speed it up. Blue tiles will cause it to leap forward.

I recently finished a game for the Cre8 Jam. You control a robot through commands to move through and scan a 3d environment. I would have added a bit more or fixed it up better, but I'm about out of time for the jam and really low on tokens. Even after using special functions to lower the token count.

You can get more information through the HELP command, but the main commands are:

MOVE (direction) (amount)
TURN (left/right) (amount)
WAVE
SWITCH [name]
SCAN (dot size)

And another important one is RSCAN, which is just SCAN, but repeatedly scans.

I would highly recommend checking out the itch.io page, as its design is special for this game.
https://werxzy.itch.io/sb-1800 The source code for the game and the map editor are also available on the itch.io page.

Use RIGHT ARROW to accelerate when on the ground
Release RIGHT ARROW to fall faster when in the air
Press UP ARROW to start a new level
Press ENTER and select SEED in the menu to start from level 1 if you want a fixed series of levels

Number on top left is a timer for your run of the level, counted in frames (at 60fps), on top right is the sum for all the levels in your session. For example a casual run of all the seeded levels from 1 to 10 took me 14027 frames. My PB for level 1 is 1071.

Source as p8 are available on https://nusan.itch.io/smooth-ride in two versions, the "comment" version is what I coded with additional comments, so it's readable but the "minimal" version uses a tool (https://thisismypassport.github.io/shrinko8/) to makes it even tinier, it's not readable but it fits into the 1k compressed bytes target
