For your games, you could have to manage a score greater than 32768 (I like games were I can score millions), and often, you want the score displayed in a fixed length, prepended with zeros (00072635).
But managing this can consume lot of tokens.
I came accros a solution I'm quite proud (I'm still learning Lua...) and wanted to share.
In Lua, if you do : "the score is "..score , score is converted into a string and then concatenated to the first one.
So to convert a number into a string, you just have to write : ''"..score
I wrote a recursive function that takes a string and a number (the length) and returns a string padded with zeros at its beginning to reach the desired length :
function pad(string,length)
if (#string==length) return string
return "0"..pad(string, length-1)
end
score=723
print(pad(""..score,7)) -- will display 0000723

Elegant and thrifty, isn't it ?
Then, you can use two variables, score2 will store the 10 thousands, score1 anything under 10000
each time your player scores something, you add it to score1 and you test if it's above 9999 :
if score1>9999 then
score1-=9999
score2+=1
end

Hello, i'm coding a character movement but it don't work, why ? :(
Code :
function _init()
hero = {}
hero.x = 64
hero.y = 64
end
function _uptade()
if btn(0) then
hero.x = hero.x - 1
end
if btn(1) then
hero.x = hero.x + 1
end
end
function _draw()
cls()
spr(0,hero.x,hero.y)
end
|
my character don't move :(

A howto about rotating a sprite around its center...
Use left and right arrows to spin the sprite.

Hi, for a game I'm working on, you can choose between two characters. But I dont have enough space to store the two characters in the same cart. I was thinking about releasing two carts, each one with a character.
The issue is that a given thread in the BBS only show the most recent cart in the "splore" of Pico 8.
Do I need to make two separate threads then ? Or is there a way to show or choose what cart is shown in splore ?
I could also try a multiple cartridge thing, like with a main cart with a selection menu, and two cart for the characters. But I dont think it work in web player or in splore. You would need to download the 3 carts manualy.
Is there a better idea than two separate threads ?

Accidentally found a fun wavy transition effect while screwing around with math.
I added nice comments to the source. Try pulling it down and tweaking the values to see if you can make it even cuter-looking.
--timer t=0 function _update() --increase timer t+=0.05 end function _draw() cls() --this crazy bit loops through --limited background colors, --and changes it when the --screen is covered with white local c = 12 + ((t-2.55)/4)%4 rectfill(0,0,128,128,c) for i=0,8 do -- column loop for j=0,8 do -- row loop --x positions are snapped --to 16px columns local x = i*16 --this number sweeps back --and forth from -1 to 1 local osc1 = sin(t+i*0.1) --this number also sweeps --back and forth, but at --a different rate local osc2 = sin(t/4+j*0.03) --y positions are influenced --by one of the sweepy --numbers local y = j*16 + osc1*10 --the circles' radii are --influenced by the other --sweepy number circfill(x, y, osc2*15, 7) end end end |

Is it possible, to modify the speed of the (keyboard) cursor if you hold one key down.? I think it is too slow and I want to tweak it, to let the cursor move at a higher speed. This might be something for the config.txt.

Since P8 has a 32k limit on numbers, what's the best way (or a way) to have numbers in the 100 thousands or millions and so on?
I mean, I guess I could super fake it by just printing out zeros after a low score integer but is that really the best way to deal with it?

Oh no! There's been a disaster, and your crew has gotten lost at sea. Luckily, you've got a supremely buoyant sailboat: it's up to you to pick them up and tow them back to safety!
Controls:
-Arrows for movement
-Z to toggle UI
-X to swap palettes
I went with some extra self-imposed challenges on this one:
-1-bit colour
-No text
-No assets (i.e. sprites, tiles, sounds, or music)
Made for #simplejam.

This is a set of sprites and functions that allow the user to draw text with a proportional font. The font covers upper and lowercase, digits and basic punctuation. This set is not as compact as the others right now, demanding 16 sprites, but it provides, IMO, more readable characters.
current version:
- switched from using the bottom 16 sprites in the first page to a 4x4 area in the first page
- restored all characters to their intended designs

UPDATE: (0.2) Updated the mouse library so that the cursor can be driven by the gamepad OR the mouse at any time, to make the cart compatible with all Pico-8 devices.
I'm cobbling together a UI/mouse library for my own use, and thought it might be useful to others. For now the only widget is a button, but I wrote the API so that it's easy to modify and extend (in theory). Will provide more documentation if there's interest.
This would be a quick "hello world" with the library, for instance:
--button "onclick" callback function hideme(this) this.visible=false end function _init() --enable the mouse and --set the cursor to a 6x6 sprite --at index 0 mouse_init(0,6,6) --create a new parent UI and --make it the active one mainui = ui_make() ui_setactive(mainui) --make a button labeled "hello, world!" --which calls hideme() when clicked. --It will draw at screen position (30,30). --I could also optionally specify a width and height, --but if I leave it out the button will be sized automatically --based on the length of the label text. btn_make(mainui, "hello, world!", hideme, 30, 30) end function _update() --update mouse position and do event callbacks --as needed mouse_update() end function _draw() cls() --print mouse position print(mouse.x.." "..mouse.y,0,0,7) -- draw mouse on top of UI ui_draw() mouse_draw() end |

As I already says in a topic in the Pico8 forum, I'm going to make a Pico-8 stand for a French retro-gaming convention during Fall (at least this one, but I hope to be able to deploy my stand in more locations!)
My goal with this stand is to allow people to discover Pico-8 and I will also run a simple jam for the interested people.
The stand will be made from Raspberry Pi (I have a few of them) connected to CRT monitors (or whatever is available) potentially two CHIP as soon as there is the update that include Pico-8 also connected on CRT or other screen, depending on the availability (hopefully the people that organise that even can lend monitors, that's really handy! :D) and my Picade with a rPi3.
Basically all of the Pi/CHIP will be connected together on a private network (I want this stand to be autonomous, because some convention can't provide an internet access, so I want them to be able to run without an internet access.
So on that network, either a computer, or one of the "Pico computer" will also have an offline BBS that will allow splore to work as if it were online.
I've found how the BBS is working and it's not really hard to make it work using DNS spoofing, but I really hope that ZEP will provide at some point a way to have our own offline BBS (at least an option in the config file to change the BBS address for such uses)
The best would also to directly submit a cart from Pico-8 that would be marvellous, but I may ask too much there :)
Anyway, all the Pi (and I will see for the CHIPs) will run a specialised version of Linux that boot directly into Pico-8 and will provide a way to upload cart to the offline BBS, need to check for that.
Anyway, I'm going back to the original goal of this blog entry.
There is something that all good stand need: a stunning logo, and the Pico-8 logo is a really stunning one because it's blocky and colourful! And how to make it even better? make it shine in the dark using LEDs.
I've been working on that for a few weeks now, and I've finally done the mechanical part, as I have access to a laser cutter, I had great fun today with it, and cut what will be the shiniest Pico-8 logo!

Hey all, me and a friend have been talking about the possibilities of being able to split a pico script into multiple files and compile them as they're edited for a while, so here is a python script that'll let you do that, hopefully it works well.
https://github.com/ambocclusion/pico-8-compiler
Let me know what you think!
Also if you plan on using it, back up frequently or use version control as it might end up wiping your file more than once because it's super destructive!!!!
