While enabling mouse input:
POKE(0x5F2D, flags) -- where flags are:
0x1 Enable
0x2 Mouse buttons trigger btn(4)..btn(6)
STAT(34) -- Mouse buttons (bitfield) with
0x1: Left
0x2: Right
0x4: middle
poke(0x5f2d, 3)
function _update()
if (stat(34)==1) print("l")
if (stat(34)==2) print("r")
if (stat(34)==4) print("m")
if (btn(4)) print(4)
if (btn(5)) print(5)
if (btn(6)) print(6)
if (btn(🅾️)) print('🅾️')
if (btn(❎)) print('❎')
end |
Left mouse button (1) triggers button 5 (❎)
Right mouse button (2) triggers button 4 (🅾️)
Shouldn't this be the other way round?

This cart runs ok at first but fails when returned to from the breadcrumb.
code:
::_::
cart='#'
for i=1,5 do
cart=cart..flr(rnd(10))
end
cls()
print(cart,64-#cart*2,4)
flip()
load(cart,"leave "..cart)
goto _ |
There's no newline after "goto _", adding one fixed the issue.
This only happens on the bbs.
Just a quick experiment, slightly related to magnetic fields around wires and strange attractors.
10 minutes coding and hours contemplating...
Have fun!

Lorenzo 2! The result might be different but for the same reasons.
(x): reset
(o): toggle trace
This template enables mouse pointer locking thanks to the JavaScript Pointer Lock API & Pico-8's GPIO system. The mouse pointer will get locked inside the pico-8 frame, while still providing movement deltas from your mouse. Now you can do a proper Marble Madness or Quake remake!
here's a demo cart (also included in the zip below):
Of course it doesn't work as advertised here on the bbs, nor within the pico-8 binary. You'll get stuck when the pointer quits the frame.
-
unzip ubmlock.zip in your template dir:
Windows: C:/Users/{Yourname}/AppData/Roaming/pico-8/plates
OSX: /Users/{Yourname}/Library/Application Support/pico-8/plates
Linux: ~/.lexaloffle/pico-8/plates - load the cart in pico (fotubigibu until I figure out how to change its name. I kinda like it though):
load #fotubigibu-0 - export as html, using the above template:
export mlockdemo.html -p ubmlock - have a taste of freedom!
The mouse handling code is in the first tab:
mouse.lockable : true when the cart is run from the proper html template, false otherwise
mouse.locked : true when the mouse is actually locked within the web browser, false otherwise
(for instance you might want to pause and print a message for the user to click back)
mouse.dx, mouse.dy : mouse deltas!
mouse.x, mouse.y : mouse coordinates, still updated and available for your menus even when the mouse is locked
note that you'll need to call mouse:update() every frame to... update the stuff above!
also the mouse buttons and wheel are not handled here, but still available through the usual stat()
when not lockable there's a fallback to standard mouse input while still trying to provide deltas, for dev purpose, with the result you can see above.
Free to use and modify, no attribution required, have fun!
they're clamped to color 15 it seems.
not a big deal, but maybe it's an easy fix?
this happened to me a couple of times in the last few days, and just now: I left pico-8 running (not a cart, console prompt) and found it completely irresponsive after something like two hours...
windows 10, pc didn't go to sleep (I usually manually Win+L, but not those times)
edit: 0.2.0d - missed an update ;)
Wandering carelessly through space you get swallowed by b'Ah, the semi-sentient semi-cybernetic semi-grumpy semi-planetoid! Now fight your way to its other end (there's one)!
Still in need of some polish here and there but (hope)fully playable, so here it is!
(edit) moved from w.i.p. to cartridges after all. some update still coming up later on...
just a very old very unfinished project, not playable but small and hopefully readable.
free to use and modify or take from, make something awesome and have fun!
standard version (export from 0.1.11g):
https://www.lexaloffle.com/bbs/files/13845/crt_template.zip
unzip crt.html to {application data}/pico-8/plates
then
EXPORT GAME.HTML -P CRT
alternate version (see here):
https://www.lexaloffle.com/bbs/files/13845/ubcrt_template.zip
Feel free to use & modify, no attribution required.
Have fun!
Connect the pipes!
There's an auto-connect feature to help you (most of the time). It can be disabled through the pause menu.
Reset the cart to replay a game (sorry!)
Early but old wip, I don't think I'll have time to work on it for a while so here it is, instead of gathering dust all alone.
This was inspired by a minesweeper puzzle I saw in a paper magazine years ago.
- tag bombs with (X). once you've tagged 20 cells the board is revealed
- tag free cells in green with (O) (in easy mode only)
-
the bomb count does not include the cell itself (a '0' cell can contain a bomb)
- new version with mouse support (from 2019, forgot to post ¯\(''/)/¯).
- some polish still needed, so still w.i.p.
older version:
Fixes:
- pixel-perfect fullscreen (requested https://www.lexaloffle.com/bbs/?tid=28615)
- fullscreen mouse support (reported https://www.lexaloffle.com/bbs/?tid=28295)
- browser zoom (ctrl+/ctrl-) doesn't break fullscreen (also reported above)
- tab key disabled (https://www.lexaloffle.com/bbs/?tid=28844)
- select & drag disabled (https://www.lexaloffle.com/bbs/?tid=30380)
- context menu disabled on canvas & buttons
- gamepad support (krajzeg's https://github.com/krajzeg/pico8gamepad/)
Features:
- pixel-perfect auto-resizing (optional, set autoresize to true in html)
- minor enhancements (pico8 palette colors, black frame with shadow)
- play button when autoplay is denied (in compliance with autoplay policy changes in chrome 66)
Tested on:
- win10 (chrome,opera,firefox, edge(blurry as expected, [email protected]))
- linux mint (chromium,firefox)
- macos (safari)
- itch.io, site & app (min embed size is 516x540, close fit with borders without autoresize)
How to:
unzip ub.html to {application data}/pico-8/plates
and then
> EXPORT FOO.HTML -P UB
minified version:
> EXPORT FOO.HTML -P UBM
Download:

It seems I'm using these a lot, so here they are:
-----------------
-- table as string
-----------------
function tab2str(t)
local s="("
for i,v in pairs(t) do
if type(i)=="number" then
s=s.."["..i.."]="
else
s=s..i..'='
end
if type(v)=="boolean" then
s=s..(v and "true" or "false")
elseif type(v)=="table" then
s=s..tab2str(v)
else
s=s..v
end
s=s..','
end
s=sub(s,1,#s-1)--remove last comma
return s..')'
end
----------
-- example
----------
l={1,2,4,5,s=5}
print(tab2str(l))
|
----------------
-- clone a table
----------------
function clone(t)
local c={}
for i,v in pairs(t) do
c[i]=type(v)=="table" and clone(v) or v
end
return c
end
|
---------------------------------------------------
-- sort a table (insertion sort)
-- cmp(a,b) should return true when a,b are ordered
---------------------------------------------------
function insort(t,cmp)
for n=2,#t do
local i=n
while i>1 and not cmp(t[i-1],t[i]) do
t[i],t[i-1]=t[i-1],t[i]
i-=1
end
end
end
----------
-- example
----------
function ascending_y(a,b)
return a.y<=b.y
end
t={}
for i=1,5 do
add(t,{i=i,y=rnd(10)})
print(i..': '..t[i].i..' '..t[i].y)
end
print("----")
insort(t,ascending_y)
for i=1,#t do
print(i..': '..t[i].i..' '..t[i].y)
end
|
-- note: better version by kittenm4ster, read below
------------------
-- shuffle a table
------------------
function shuffle(t)
for n=1,#t*2 do -- #t*2 times seems enough
local a,b=flr(1+rnd(#t)),flr(1+rnd(#t))
t[a],t[b]=t[b],t[a]
end
return t
end
----------
-- example
----------
t={1,2,3,4}
for i=1,#t do
print(i..': '..t[i])
end
print("----")
shuffle(t)
for i=1,#t do
print(i..': '..t[i])
end
|
------------------------------
-- random element from a table
------------------------------
function trand(t) return t[flr(1+rnd(#t))] end
----------
-- example
----------
l={1,2,3,4}
print(trand(l))
|
-- note: a little overkill token-wise, read below (thanks felice!)
-----------------------------------
-- stack (lifo: last in, first out)
-----------------------------------
lifo={
new = function() return setmetatable({d={}},lifo) end,
clear = function(m) m.d={} end,
len = function(m) return #m.d end,
empty = function(m) return #m.d==0 end,
push = function(m,v) m.d[#m.d+1]=v end,
pop = function(m)
local v=m.d[#m.d]
m.d[#m.d]=nil
return v
end
} lifo.__index=lifo
----------
-- example
----------
stack = lifo.new()
stack:push(10)
stack:push(20)
stack:push(30)
while(not stack:empty()) do
print(stack:pop())
end

I think some of these would be handy as part of the pico8 api (clone,sort,shuffle...)
feel free to criticize, comment, correct mine, post yours...

v1.2:
- went other directions ;)
v1.1:
- digging mechanic
- down button: soft drop with soft lock
- up button: hard drop with hard lock
v1.0:
Work in progress!
note:
I made the game quite forgiving, and I just realized it's still playable without even cycling the colors.
maybe I could ditch the cycling altogether? or make it a difficulty option? what do you think?
Here's a simple one:
use stat(x), where x is:

This game should have been released a year ago! I exhumed it this year, hoping I could polish it for good. but it seems I'm falling short once again! I'm not putting it back six feet under though, so here it is, in its (appropriate) semi-zombified state, in time for Halloween!
so, still a work in progress, but fully playable though. mostly the sound effects need some work...
Happy Halloween!
There's quite a bunch of pico-8 games on arcadeprehacks. they're leeched from here, and modified with "trainer" options. ads all around, no acknowledgment nor links to the original stuff. at least they could add a cracktro!
found the site searching for my "pellet muncher" on google. I lol'd at first. sad thing is, there's 1300+ "plays" there, while I painfully got a hundred "views" on itchio plus gamejolt. well, at least there are people playing my game...
here's a wip of another take on my tetramino-making mechanic (T-Factory 1)
hopefully a little more appealing / a little less awkward (?)
