How to doodle a distorted electric guitar waveform?

Sun, 20 Oct 2024 13:32:05 UTC

Any ideas on how to doodle something that sounds at least remotely like one?

Check if a given SFX (0-7) is a custom waveform or not

Fri, 04 Oct 2024 09:23:10 UTC

There are 8 sound effects (№0-№7) that can be interpreted either as a custom instrument or a custom waveform. Where in memory does a pico-8 cart store information about what sfx is in waveform-mode? Im guessing there's a byte somewhere in memory with each of its bits corresponding to each SFX mode. The question is - what's the address?

VJ8 - A PICO-8 VJing tool

Add visuals to your music

Get your best playlist blasting, get VJ8 rolling and get the rave going! Use your joystick to change ANIMS - short procedural (or not) animations that put you into trance (effect not guaranteed). Comes with a free distasteful demo song!(i cant make musik)

Use your own animations

Grab your old fancy demos and tweetcarts and turn them into something to be played at the party - just drop the code into VJ8.

The beat's about to drop

Hold the X button during intense parts of your song and let the visuals do their work.

Controls:

What are anims & breaks (manual from tab №2)

Your thoughts on Pico-8's "fantasy" year of release?

Wed, 17 Jul 2024 10:13:16 UTC

Hey everyone.
What year do you think Pico-8 would've been released if it was a real console that physically existed?
Late 80's? 90's? Before or after NES? Let's talk about this.
P.S. Another topic, would Pico-8 be a hand-held or a home console? Personally, I think
it'd be a cube-shaped home console, square-sided just like its display. Similar to GameCube but more "cuber" (with equal dimentions) and quite small in size. Regarding the colors, i think dark grey body with a red outline would look stylish. Like on the picture, but a different color.

Minesweeper by Collin

A second take on the minesweeper game. Priginally made in 2 hours and polished a couple of months later.

D-pad - navigate
X - Reveal tile
O - mark tile as flagged

Reveal numbered tiles when there are enough flags around it to reveal all neighboring unflagged tiles.

Random loot system

Sat, 27 May 2023 08:15:55 UTC

so today i made this
use it as you want guys
also maybe it's not token-efficient but
i'll leave it up to you

function randprob_from(l)
	--the function expects an
	--array of tables like these:
	--{p=0.5,v='item name'}

	--a "p" value between 0 and 1
	--and a "v" value.

	--"p" is propability of the
	--"v" value being returned

	local lim=1
	local value=rnd()
	for pos in all(l) do
		highlimit=lim
		lim-=pos.p
		lowlimit=lim
		if value<highlimit
		and value>=lowlimit then
			return pos.v
		end
	end
end

Hello! I've made a cart on my console and it runs there. But when I upload it onto BBS, it gives a syntax error.

Error:

2d line map editor

Tue, 15 Nov 2022 19:44:46 UTC

2D Line Map Editor 1.0

by collinthenewmaker

[Click to Play]

This tool allows you to map lines on a plane and export them into any of your carts.

Each line is represented as a table with values x1,y1,x2,y2.
This is useful for raycast projects or whatever you need to map lines for.

Buttons (left-up corner of the screen, top to bottom):

Temp save: temporarily saves all line data to adresses 0x4300-0x5dff in console memory.
Load: loads data at adresses 0x4300-0x5dff. Can be used as reserve copy.
Toggle ruler: Each line displays it's length to the right of it's 2nd point.
Export: allows you to type in your desired cart's name and export line data to it's addresses 0x4300-0x5dff. This overwrites your cartridge file so make sure you don't have anything valuable in there (sprites, map, sounds and, obviously, code are safe).

Modes: (down side of the screen, left to right):

Click: right-click to select the line and distplay it's info, left-click to deselect.
Pan: left-click drag across the plane to view different parts of it.
Draw: left-click and drag to create a new line at your pointer position.
Delete: left-click near the line to delete it. Lines that will be affected are highlighted red.

Memory:

Each line takes 8 bytes of space (2 bytes per 16-bit variable, 4 variables).
All memory in the aforementioed range is cleared before writing line data.

How to read line data back:

In your original cartridge, you can do something like this:

lines={}
for i=0x4300,0x5dff,8 do
 local x1=peek2(i)
 local y1=peek2(i+2)
 local x2=peek2(i+4)
 local y2=peek2(i+6)
 local line={x1=x1,y1=y1,x2=x2,y2=y2}
 add(lines,line)
end

Dealing with range overflow

Sun, 13 Nov 2022 22:09:50 UTC

How do you deal with range overflow? The numbers beyond 32767 warp to -32766 in pico8's 16 bit signed system when calculating. This is sometimes enough, but not always. For example,

 function distance(x1,y1,x2,y2)
  return sqrt((x2-x1)^2+(y2-y1)^2)
 end

will sometimes (very often actually) return 0 as a result of taking sqrt of the negative wrapped number. This is occasionally crutial. Is there a workaround to compute this as if this was an unsigned system?

Transferring data between cartridges

So i watched lazy devs' youtube shorts about how he makes his shmup levels. In there he mentioned that he has different pico8 cartridges that work as tools for editing stuff like sprites, bullet patterns and level scenery. I coded a 2d space line editor that can be used for raycasting. How can i transfer all lines data to an another cartridge for use? There is a big "lines" table that containes tables with individual line data. I know that you can't transfer actual code or tables between carts so lazy devs should have used something different.
