A basic rundown of a faster Bounding Box solution.

It uses screen partitioning to select only near objects to check for collision. What is currently running is essentially a worst case scenario where all objects are searching for all other objects with no direct referencing.

The Algorithm

function buildarr()
	colarr = {}
		for y=0,18 do
			colarr[y] = {}
			for x=0,18 do
				colarr[y][x] = {}
			end
		end
end

function entcol(self,name,action)
	xx = flr(self.x/8)+2
	yy = flr(self.y/8)+2
	for xt = xx-1,xx+1 do
		for yt = yy-1,yy+1 do
			for obj in all(colarr[yt][xt]) do
				checks += 1
				if (obj.name == name and obj!= self and boxcol(self,obj)) action(self,obj)
			end
		end
	end
end
coladd = function(self)
		xx = flr(self.x/8) + 2
		yy = flr(self.y/8) + 2
		add(colarr[yy][xx],self)
	end

Hello! This is my second Celeste Classic mod, this one is a little longer. It includes several screens modeled off of counterparts from newleste's Forsaken City.

Basically the title.

info([cart])--returns tokens,chars,compressed_size of [cart] or the current cart if given none

This could be useful for people who are creating carts using printh() and such, to detect if the cart is able to be run before load()ing it:

tokens,chars,compressed=info("cart.p8")
if(tokens<8192 and chars<65536)load("cart.p8")

What do you all think?

Hi,

First, I'm a noob regarding Linux and alikes. I've been trying for last 24 hours to make my Picade (a small arcade bartop by Pimoroni, running on Raspberry Pi 4) start into Pico-8 in Splore mode. It boots in the desktop and I usually launch Pico-8 manually in the console with:

~/pico8/pico8 -splore

(my folder is pico8, not pico-8)

Works well, figured I could as well make Raspberry OS do it for me.

How naive.

Followed tens of tutorials, with no success. To the most, it looks like Pico-8 launches for a second then closes. Feels like this because there's a black screen opening that closes 1 sec later. I've made a .sh file with:

echo 'Launching Pico-8...'
/home/pi/pico8/pico8_dyn -splore
echo 'Pico-8 closed'

with 'pico8_dyn' in place of 'pico8' if that matters. If I run it on console it works with the added echos on start and closing of Pico-8.

Then I made a autostart file at .config/lxsession/LXDE-pi/autostart:

@lxpanel --profile LXDE-pi

Hello! I'm new to PICO-8, and loving it. I'm not new to programming or game dev.

I've collected a list of questions/thoughts, in no particular order...

1. Sharing: I've uploaded my first game to itch.io, rather than here, so I can customize the HTML around the player. Is it bad BBS etiquette to link to games on itch? It seems popular to directly share games here, not link to self-hosted or third-party.

2. Single-player: Is there a way to indicate a game is single-player? Maybe a register to Poke()? Ideally it would remove the "Player 2" controls from the Controls screen.

3. Exporting: I like that you can EXPORT the map, spritesheet, etc. "headlessly" via the commandline. Personally I love build scripts, and automatically exporting things. But is it impossible to export a cartridge (.p8.png) and music (.wav) by headless commandline? I must open the editor and type the commands?

4. Music: Does the Speed of a SFX correlate to a traditional BPM? Is there a formula? Or, is it not guaranteed to play back at one BPM depending on platform, etc. (I have seen this other thread, about roughly tracking the state of the music player https://www.lexaloffle.com/bbs/?pid=10719#p10719 )

5. HTML Export: When the p8 file contains a label image, and title (first comments in code), it would be neat to generate OpenGraph meta tags for the HTML (so you get a sleek preview card, when sharing your game)

6. Binaries: Is there a way in-code to know what platform you're playing on? Windows/Mac/HTML with touch controls, etc. Currently I detect HTML with/without touch by writing GPIO bytes from the HTML page.

7. Conventions: The "O" and "X" buttons... is the "O" conventionally Action/Confirm and the "X" is Secondary/Cancel? Like a Game Boy layout?

8. Menus: When you add a custom menu item, such as "TOGGLE MUSIC", and the callback function is triggered, is the game supposed to update/advance one frame? It seems to happen to me, but not 100% of the time, inconsistently. Maybe a bug?

That's all for now. I left out some other questions I've mostly solved.

Thanks for any guidance!
