Requires mouse & keyboard

This started off as: "I wonder if I can get the ZX Spectrum font into pico-8?"
I then realised that 16 chars per line isn't particularly practical, and wrote a font editor.

Features:

  • edit, save, export fonts for use in pico-8
  • change width & height of font characters
  • adjust width per character
  • cut, copy, paste, undo, nudge
  • 8 internal save slots
  • exports a .txt file to desktop that will run in pico-8 to use the font in other projects
  • uses ZX Spectrum font as initial template

Limitations:

  • save/export won't work in browser
  • only edits the main 96 characters (i.e. Spectrum font)

If I view a post on the BBS and scroll down to the bottom to post a comment, there are two buttons: Submit, on the left and Preview, on the right.

If I click Preview I'm taken to a new screen. The first issue is that I've just clicked a Preview button but I'm not shown a preview just a larger text box. To actually see the preview I have to scroll down and click the Preview button again.

Which brings me to the second issue: The Preview button is now on the left and the submit button, now called Publish Changes, is on the right. I would expect the buttons to still be in the same place and the number of times I've almost posted half a comment because I almost clicked Publish when what I wanted was Preview are many.

Minor issues. Not the end of the world if it never gets fixed—at this point fixing it might cause as many or even more mistakes than not fixing it so maybe it's just not worth doing—but thought I'd point it out anyway.

I thought it was strange to restrict update posts to twitter, so here it is!

This is a project ive been working on for a few months and so far its about 1/4th the way done! now what is it though?

This is a game based of Scanner Sombre, a game/trend that was popular for about 2 weeks. Normal scanner sombre is a 1st person horror game where you cannot see and must use a Lidar scanner to sort of "Paint" dots on surfaces to see. after i watched Fundy make his version, i thought to myself: "huh. why cant i do that too?"

Then i decided to make a scanner sombre type game in pico-8! Obviously i do not have the brain power to make a 3D game in pico-8, so i decided to do something more... Creative. I opted to make it a top-down maze game with some puzzle elements and obstacles. The only catch, is that you Cant see the maze. obviously. Puzzle elements i will show later, Ill show the chase sequence after that, and then ill update you all if i add any other big features. for now, here is what i CAN tell you.

The Game

This ​game is ​​about buying and selling goods and traveling between outposts There are two types of goods: contraband and normal trade goods. The rules of the game are simple, you have 300 days to make as much money as possible and have the outposts up to level 3. Leveling outposts is completed through "outpost requests". These will upgrade the outposts so that they produce more.

The "hard mode" of the game is to complete all the outposts without selling any contraband.

Hello all.
I'm probably missing something really important but I'm trying to put a gradient sky on my game.
I spotted some code I thought would do the trick in another thread.

```
poke(0x5f5f,0x3c) -- 0x3c is the colour of the blue sky to be replaced.
pal({[0]=0x82,0x82,0x84,0x84,4,4,0x89,0x89,0x8e,0x8e,0x8f,0x8f,15,15,0x87,0x87},2)
memset(0x5f70,0xaa,16)


It's supposed to do a sunset gradient-styled sky, but I only get this:



Editing the colours in the table result in the same!

Ideally, I'd like it different shades of blue as in the other example, but I'll cross that bridge later.

Can someone please help out with what I'm doing wrong?

Thanks in advance

How can you move something along an outward spiral with consistent speed?

The method I have been using to make stuff move in circles doesn't quiete work with spirals because the change in angle stays the same while the circumference gets bigger.
This causes the object to accellerate as it moves outwards.
Is there any way around this?
I tried changing the amound by which "t" changes each frame to act as a speed correction but I get weird results, because it either goes below zero and changes direction or I run into the fixed point limit because all values are so small. Not that any values I tried to dercrease "spd" by each frame actually fixed the accellaration issue before acting up in the first place.
This gets even worse at 60 fps of course.
I don't feel like I am coming at it from the right angle.
Am I missing some completely different way to make spirals?

out=10
t=0
spd=0.01

function _draw()
	cls()
	out+=.2
	spd-=.0001
	t+=spd

	circfill(sin(t)*out+64,cos(t)*out+64,1,5)
	print(t)
	print(spd)
end

I was looking at the Pico-8 changelog and saw that themes were made easier to change. this got me thinking, how hard would it be to make a custom theme, or even accompanying thememaker.exe program? this seemed really cool to me, so i threw myself headfirst into pico-8's files. here are my findings/questions i have.

Firstly, in "pico8.dat" i found that it not only contains data code which i have no idea what it contains, but it also contains a lot of pico-8 code! after a bit of digging, i found that in this order, this pico-8 code is:

1: the pico-8 boot sfx
2:pico-8 democarts
3: i have no clue

I also found around 5 copies of the same lines of terminal syntax (eg 'ls' 'folder' 'load' etc.), which is interesting. i was mainly looking for the color codes that tell pico-8 what colors certain UI elements are, but i could not find them. they had to be in the mess of .dat stuff.

After awhile, i found that pico8.dat is byte-checked, meaning that pico-8 wont boot if pico8.dat has been altered at all. makes sense, it would significantly impact monetary gain if everyone could just write their own pico-8.

Took a shot at arranging a beautiful song into a chiptune version.

Does it work?

Should I finish it?

Particle Effects

Sixteen different kind of particles based on same generation method. I get the idea of the main function and loop of the particles from Youtube video of "Particles in Pico-8 - The Ultimate Guide" from SpaceCat.

All functions work and genrate particle when "O" button is passed. The particles can be implemented to other carts by only copying the function into the code. So, everyone is free to use the particless as long as they refer to my work :D

update 2024: the 0.2.6 update improves things! search the update post for menuitem(0x301 for details. (My original menuitem post remains below, unchanged)


PICO-8 has fancy menuitems but there are some gotchas and bugs to be aware of.

Here's an example of what I do by default; the rest of this post will explain how the code works and why I do things this way:

it's not a game at all it's just a reimagining of five night's at pico (https://www.lexaloffle.com/bbs/?tid=31672) (the gif is pretty bad)

Info:

I thought I would share this alpha of an fps I am working on. It is far from finished but I thought some feedback
would help.
most if not all graphics are placeholders.
If you want to look around the code of modify it, its fine with me. I have also uploaded the Base engine, but it is
missing afew variables for draw distance fov and similar things.

Controls:

p2 left and right to look around.
p1 dpad to move.
press p2 up for the map, and down to shoot.
pressing p1 X/O will switch weapons which hasn't been fully added.
on the menu you can change the draw distance and scaling of lines,
you can also force change the game state.
