Hi @zep!
pico8 0.2.6b / linux:
cls() if (false)?1 --hi print(2) print(3) |
expected output: 2 3
actual output: 3
Here's an altered version that works as expected:
cls() if (false)?1 print(2) print(3) |
(this prints 2 3, as expected)
3 things seem required to trigger this bug:
- shorthand if
- shorthand print on the same line
- !! further text after the shorthand print (" --hi", in this example. but just a single trailing space triggers the bug too)
When these are all true, the next line seems to get scooped up into the shorthand line. This can include attaching an else to the wrong if, like in this more complicated example:
cls() if false then if (false)?1 --hi else print(2) print(3) end print(4) |
expected output: 2 3 4
actual output: 4

Hello good people of the Picotron! First time posting. I apologize if I<m not posting in the right forum, but I<m a bit lost in the current layout of the site.
I'm a amateur programmer who never went too far qith this hobby, so I thought maybe something meant to be "easy" like Picotron could be a thing for me, the eternal wannabe game designer.
My question to day is about tables.
I can<t quite get them to work. I use simple one dimension arrays, but I need more of a Pascal-type of record, and when I read the Lua documentation, it seems to be possible, but my code doesn<t compile when I try to create tables with more than one dimension or different types of variable. It<s a syntax problem. I know what I want to do, but I can't find the right syntax.
For instance, in my RPG, there will be a party of six characters. So I need a table with at least a string column for the name of the character, a number column for the character sprite number, one column each for the chacter<s abilities. At the end of the day, there will be a lot of data in that table.

Title says it all.
I'm making a horizontal scrolling game with a map 32 screen wide and 1 screen tall, and with the player using extra colors different from the enemy colors. (enemies can't be over or under the player).
For this, I'm using screen rotation, but now I can't use print to display text any more as it appears rotated.
Has anyone already implemented a 90° rotated print function ?

Hi, I encountered a waveform corruption bug while trying to move SFX as part of a multi-composer collaboration project.
On version 0.2.6B
Reproduction steps:
1) Make a custom waveform in SFX 0
2) Make in SFX 1 make a sequence using SFX 0
3) Make in SFX 2 make a sequence using SFX 0
4) Move (cut and paste) SFX 0 to SFX 4
5) Move (cut and paste) SFX 1 to SFX 5
6) Move (cut and paste) SFX 2 to SFX 6
7) Check SFX 4, the data will be corrupted
It seems that this can happen with other combinations but this is the procedure that caused the bug to happen and is reproducible on a fresh cart.
The corruption seem to be an inversion of the sign of alternating sample of some sections of the wave

Celeste but a black hole is chasing you.
The black hole speeds up over time. Here is everything that increases it's speed:
- New level (Biggest increase in speed)
- Death
- Dashing (Smallest increase in speed)
Getting berries decreases speed.
If the hole is more than 2 levels away, it starts to get a speed multiplier.
The formula for speed goes something like this:
(distance is distance between blackhole and roof of current level)
(0.025level + 0.01 deaths + 0.005 dashes)/berries + ((floor(distance)256)*2)

Controls:

Arrow keys to move
The only power-ups are the strawberries, nothing else is a power-up.

You are a space fighter who is currently fighting in the war of Andromeda. You were told to go to fight a battle against the evil aliens and you were told that people would be joining you to fight. But nobody showed up. You are all alone fighting 20 waves of evil aliens. Can you do it? Can you defeat the Gorthen and end it all?

We definitely need an option to download carts in splore. I bought this for my steam deck expecting the standalone app to be, well, standalone. I have to reboot my whole system to access the web browser and file explorer needed to download and add carts. It's very frustrating that such an essential feature was ignored. I doubt there's any chance for a refund, so I guess I'll just have to beg for features that should have been included from the start. Maybe if I'm lucky it'll be added in less than a year. It's only been 9 so far..
Maybe this is overly salty, but it's very frustrating that an implied feature isn't actually present when it's the whole reason I paid for the standalone app in the first place. Buyer beware I guess...

I want to make my own raycaster game in picotron and I have been following this blog written for a pico-8 raycaster. I get an error when I run this and I am not sure what I should do to fix this issue. Help would be much appreciated.
Other than the code, all I did is make a sprite in slot 1 and draw a simple map in the map editor.
function _init()
cam={
x=12,
y=12,
a=0,
w2d=2
}
scrx=0
end
function _update()
controls()
end
function _draw()
cls()
map(0,0,0,0,16,16)
circ(cam.x,cam.y,2,12)
--for scrx=0,480 do
-- raycast(cam,scrx)
--end
raycast(cam,240)
end
function controls()
if btn(0) then
cam.a+=0.01
end
if btn(1) then
cam.a-=0.01
end
if btn(2) then
cam.x+=cos(cam.a)*0.5
cam.y+=sin(cam.a)*0.5
end
if btn(3) then
cam.x+=cos(cam.a)*-0.25
cam.y*=sin(cam.a)*-0.25
end

About:
Zap-bot is an homage to the old Gameboy era cheap SBC (single board computer) handleds and their stupid little games, like the Classic and Brick Brick game!
This is a port of the shooter line filler game inside that. Your goal is to clear the lines for as long as you can last!
Controls:
Move with arrow keys left and right.
Shoot with X.

DVD Bounce Screensaver!
Thought it would be hilarious to make one of these.
Customizable settings such as ball speed, starting color, and turning off the sound.

If you all don't care again I need help with object pickups in my game when you pickup an object (artifact) you get a score of 1 point. What I need to know is how to add a spawner for that object and how to make the player pick it up.
Many thanks.
BTW I tried to use a YouTube tutorial with no luck
--pickups
function ipickups()
pu={
x=63,
y=50,
act=true,
}
artifacts=0
end
function upickups()
if pu.act then
if abs(px-pu.x)<=4 and abs(py-pu.y)<=4 then
pu.act=false
artifacts+=1
end
end
end
function dpickups()
if pu.act then
spr(6,pu.x,pu.y,4,4)
end
print("artifacts: "..artifacts)
end |
