0.2.2 menuitems always respond to L/R??

Tue, 28 Mar 2023 04:29:40 UTC

as of 0.2.2, all menuitems now have their functions called when left/right are pushed while the menuitem is selected?? It took me an embarrassingly long time to realize this... (probably due largely to a bug where the menu doesn't actually close but the items are still triggered, even if the function does not return true which helped to obscure this behavior)

@zep it seems like this change to menuitem's functionality was intended to be extra functionality and only improve the capabilities of menuitems, but the problem is that the new functionality is always activated, even it's not needed or wanted, so if the user accidentally presses left or right (which is very easy to do with a joystick, and this is how I noticed it!) the menuitem's function gets triggered, and the only way to prevent that (i.e. in order to maintain the old behavior where left/right do not trigger the function) is to use up more tokens in the menuitem's function to check which button was pressed!

it seems backwards from most of the nice feature changes we've had in recent releases which tend to result in added convenience and token efficiency :D

I know I'm responding very late to this change :D but it seems like it would have been preferable if the new functionality was only activated if an extra param was given to menuitem or something like that...because it is very frustrating for a user to accidentally trigger "restart level" for instance when they were just intending to move down the list of items using a joystick!

exit early from print delay?

Sat, 30 Apr 2022 18:25:59 UTC

Does anyone know if there is a way to exit early when a print command is running with the \^d p8scii special command that adds delay frames in between each character?

I'm in token crunch mode and realizing this new special command could be extremely handy for easy RPG-style printing delay with zero code in certain situations, but if there was a way to exit early, it would be even more useful!

And if this is not currently possible, consider it a feature request :p

cassino

I've been playing a bunch of Cassino lately in real life, so just for fun I thought I'd try making a simple PICO-8 version of it where you play against an AI.

The suits are all just built-in PICO-8 glyphs so note that the stars are spades.

If you've never played Cassino before, it's a really fun two-player card game (it can technically be played with more than 2 players but it doesn't work nearly as well) with an uncommon "fishing" mechanic and I highly recommend trying it with a real human!

feature request: option to allow gamepad input when not focused

Mon, 27 Sep 2021 04:36:40 UTC

Feature Request:

a config.txt option to allow PICO-8 to respond to gamepad input even when the window is not in focus

I imagine this option would be disabled by default, but it would come in handy for a workflow which is very common for me, wherein both PICO-8 and an external text editor are open side by side (and sometimes also a terminal window for viewing printh output) and I want to be able to control something in the game with my gamepad, but then also be able to type in a different window using my keyboard, without having to switch windows as frequently. Obviously in this out-of-focus situation PICO-8 would have to ignore keyboard input, but still respond to gamepad input.

love,

line-drawing wraparound bug in v0.2.2

Fri, 26 Feb 2021 19:16:51 UTC

Run the cart at this link: https://www.lexaloffle.com/bbs/?tid=41062
Pick up the hen with the web
Slam into the right side of the screen repeatedly

observe that part of the lines which make up the web are visible on the left (opposite) side of the screen

This happens in v0.2.2 of the BBS player, the native version, and the HTML export from the native version. It does not happen in the previous version.

splore/binary export: cstore file doesn't correctly overlay onto cart ROM

Fri, 11 Dec 2020 21:03:58 UTC

@zep it looks like if you do a cstore from a cart in splore or an exported binary, what it saves to the .lexaloffle/pico-8/cstore folder is only those regions of cart ROM that were cstored, and then next time you launch it from splore (or next time you run the exported binary), only those regions of the ROM are copied to base RAM; everything else is blank

I'm guessing the cstore file is intended be overlayed on top of the original ROM contents when copying from cart ROM to cart RAM (and that's why it only saves the changed parts?), but it looks like there was a mistake in implementation and the cstore file contents actually are the only thing copied to base RAM?

I can't reproduce the behavior when using a p8 or p8.png file; this happens only with splore or from an exported binary

To reproduce:

load a cart from the splore or launch a binary export of a cart that contains data and calls cstore specifying a partial section of cart memory, e.g. cstore(0, 0, 0x2000) (which is what my jigsaw puzzle cart does but I'm about to change it to write the entire ROM as a workaround ;p)
exit splore or close the binary export
relaunch the cart
see that now all data regions of cart ROM are "permanently" empty, except for the spritesheet

sfx(-1, -2) doesn't stop sound if triggered by menuitem

Wed, 25 Nov 2020 21:37:28 UTC

I seem to have found a weird bug. Normally sfx(-1, -2) will stop sfx on all channels, but if it is triggered by a menuitem callback, it doesn't work; in that case only explicitly stopping sfx on each channel works

to reproduce, enter some notes on sfx 8 (so you can hear when playback stops), then use this code and compare the behavior of the two menu items:

function stop_all_sfx_short()
  sfx(-1, -2)
end

function stop_all_sfx_long()
  for i = 0, 3 do
    sfx(-1, i)
  end
end

function _init()
  menuitem(1, 'stop sfx (-2)', stop_all_sfx_short)
  menuitem(2, 'stop sfx (long)', stop_all_sfx_long)

  sfx(8)
end

function _update()
end

function _draw()
end

print(number, x, y) displays hex in v0.2.1

Sat, 04 Jul 2020 00:17:50 UTC

In the web player here on the BBS which currently says it's version 0.2.1, it appears print() now displays numbers as hex:

EDIT: oh wow I didn't realize v0.2.1 was out for real and not just in the BBS web version; I downloaded it and tried running the same cart (#xmasfish) and figured out how to reproduce it so I have corrected the title and description since my first report wrongly said the issue was with tostr()

as you can see here, it only displays as hex when x,y arguments are given to print():

btnp with _update60 stops working after resume (0.2.0i)

Mon, 25 May 2020 18:44:54 UTC

btnp seems to completely stop working iff _update60 is used instead of the normal _update

to reproduce:

run the program below
press Esc
type some sort of statement (for some reason the bug only occurs if you type something before typing resume) e.g. ?"hello"
type resume
push or hold down the button (O)

expected: "pushed" will appear onscreen
actual: "pushed" no longer appears onscreen

function _update60()
  pushed = btnp(4)
end

function _draw()
  cls()
  if pushed then
    print("pushed", 52, 60, 8)
  end
end

sprite editor: shift + q/w moves too far when zoomed

Sun, 10 May 2020 22:34:48 UTC

shift + q/w can be used to move up/down in the spritesheet, but when zoomed, the number of sprites it moves by seems to be greater than it should be, i.e. different from how normal q/w (left/right) works when zoomed.

coroutine problem with 0.2.0d (breaks Alfonzo's Bowling Challenge)

Sun, 26 Apr 2020 04:39:31 UTC

@zep seems like something in 0.2.0d (I don't know if it's present in earlier bugfixes of 0.2.0) is wonky with coroutines not updating sometimes or something?? different unpredictable problems are actually happening almost every time I run it; check this out (the dialogue is updated in a coroutine):

so far it seems like most of the time it seems to lead to crashing because variables that are declared inside coroutines are attempted to be referenced by code in the main thread but the variable hasn't been defined yet, which seems to also point to the culprit being coroutines mysteriously not updating every frame like they should (the _update60 method in this cart calls coresume on both of the coroutines every frame; there is one for the dialogue and one for controlling the presentation of the "pins" in each level--both of those are the things that seem to be breaking)

EDIT: okay I've done a bit more testing and there is definitely an issue where a coroutine just starts updating suuuper slowly (seems likely the same issue as is visible in the GIF above) and basically yields in the middle of itself where I don't have any yield statement. For reference, here is some code inside a coroutine where I added debug printh statements:

    repeat
        printh('offset.y:' .. offset.y)
        printh('vy:' .. vy)
        if offset.y >= maxtargetoffset then
            vy = -abs(vy)
        end

        printh('one')
        if targetzipy then
            if vy < 0 and offset.y < targetzipy then
                vy -= .1
            end
        elseif offset.y <= 0 then
            vy = abs(vy)
        end

        printh('two')
        offset.y += vy

        printh('three')
        for _, t in pairs(targets) do
            if not t.isknocked then
                t.y += vy
            end
        end

        printh('four')
        while playercount == 0 do yield() end
        yield()
    until state ~= state_play or all_offscreen(targets)

and here is the console output:

vy:0.09
done updating coroutines
resuming coroutine 1
resuming coroutine 2
done updating coroutines
resuming coroutine 1
resuming coroutine 2
done updating coroutines
resuming coroutine 1
resuming coroutine 2

resuming coroutine 1
resuming coroutine 2
done updating coroutines

resuming coroutine 2
done updating coroutines
resuming coroutine 1
resuming coroutine 2

done updating coroutines

done updating coroutines

resuming coroutine 2
done updating coroutines

resuming coroutine 1
resuming coroutine 2
two
done updating coroutines
resuming coroutine 1
resuming coroutine 2
done updating coroutines
resuming coroutine 1
resuming coroutine 2
done updating coroutines

you can see it's yielding all by itself in the middle of those lines for some reason?? (i.e. the "offset.y:whatever", "vy:0.09", "one", "two", "three", "four" should all be next to each other in the console but they are interrupted by several frames)

SFX editor clipboard breaks after moving SFX in pattern editor

Fri, 24 Apr 2020 18:09:18 UTC

after moving (via cut/paste) some SFX in the new super-cool pattern editor view, it seems sometimes it breaks the SFX editor's copy/paste in that when I highlight a few notes, copy them, and try to paste them, it keeps saying a message like "pasted 2 sfx" (instead of "notes") and has no apparent effect (at least not that I can see from within the SFX editor). I haven't found any way to fix it besides reloading the cart.

EDIT: actually I just saw it happen even without using the pattern editor...copy/paste just mysteriously stops working sometimes. it looks like entering some notes makes it start working again though?

"0 joysticks detected" in exported binary player

The new options menu with controls documentation is so great to have in the binary exports! :)

There just seems to be a small problem where it says there are "0 joysticks" even though I have one plugged in and it is working fine:

Backstory

My wife Aubrianne wrote a 100% completely original poem which provides the deep lore behind this game:

'Twas the night before Christmas, when all through the sea
Not a creature was swimming, not you and not me;
The lights were all strung on the coral with care,
In hopes that St. Nicholas soon would be there;
The wee fry were nestled all snug in their beds;
While visions of sugar-worms danced in their heads;
When up from the surface there came such a splashing,
I sprang from my bed to see what could be happening.

Up, up to the top I swam like a flash,
Looked up through the ripples, popped up with a splash.
When what to my protruding eyes did appear,
But a crash-landed sleigh and eight whiplashed rein-deer,
With a little old driver so frantic and quick,
I knew in a moment he must be St. Nick.

They paddled like puppies, his coursers they came,
And he whistled, and shouted, and called them by name:
"Now, Dasher! now, Dancer! now Prancer and Vixen!
On, Comet! on, Cupid! on, Donner and Blitzen!
To the shore of the beach! to this lonely atoll!
Now swim on up! swim on up! swim on up all!"
As awkward as kittens dropped into a bath,
They bobbed and they flailed and sought for a path;

And then, in a twinkling, reindeer on the beach
Were prancing and pawing the sand with relief.
As I dipped 'neath the waves, and was turning around,
Into the water St. Nicholas came with a bound.
He was dressed all in fur, which was quite a blunder,
His clothes got all soaked and were pulling him under;
I was quite astonished to hear him call out
to me he was waving and said with a shout

"What ho, my good fish! You've been very good!
I'm here to bring gifts to your fine neighborhood!
But, alas! All the presents I brought for your friends
Have been lost at sea and I might get the bends.
Our tanks are all dented, and I very much fear
we have only wetsuits for seven reindeer.
Dasher, that rascal, lost his on that trip
we took to Fiji on our polar cruise ship.

"My friend, will you help me? I'm in dire straits
For all o'er the world empty stockings await
Will you find all the gifts and deliver each one?
Will you wear the red hat and make Christmas come?"
I solemnly blooped and I bubbled assent
I would see it through to the very last present!

His hand rose up all the way to his head
and came down again with his fine cap of red
He gave it to me and he said with a sigh,
"You're Santa now, fish. You are the guy!"
With a wink of his eye, he gave me a smile
I knew I had nothing to fear from this trial;
He sloshed to the beach, and tapped his red nose
The sleigh came together and in the air rose

He sprang right aboard, the reindeer all heartened,
And away they all flew, as fast as a marlin.
But I heard him exclaim, as I floated, awestruck—
“Happy Christmas to all, and to all, best of luck!”

unstable 60 FPS in new BBS HTML player

Fri, 22 Nov 2019 21:50:28 UTC

The new (just noticed it changed today) HTML player here on the BBS doesn't seem to be able to keep a steady 60 FPS

I can really feel a bunch of frame jitter when playing Alfonzo's Bowling Challenge and it makes the physics feel very noticeably off

(testing on a MacBook Pro in both Chrome and Firefox. The old exported HTML version (0.1.12c) on itch still runs smoothly on this same computer)

HTML desktop export: side button layout broken in Chrome

Mon, 11 Nov 2019 22:13:59 UTC

The layout of the clickable buttons (fullscreen, control help, mute, etc.) on the side in the 0.1.12c version of HTML exports appears to have broken in Google Chrome all of the sudden. All of the buttons now appear stacked on top of each other :\

screenshot:

The layout still works in Firefox. I guess Chrome recently changed their interpretation of CSS rules in a way that broke this?
