aka writing down how my cart works before I forget.

This is about my game, Halloween Horrors, which is here.

This game was written very much based on previous work, with functions dating all the way back to P8C-BUN, my first game. I started from the Demystify the Christmas Tree code because I wanted the kittens. It's not very token efficient at all, but I didn't come close to running out of tokens in the end (6447/8192). Originally, I was making another Christmas game - it was only very late on that my gf persuaded me to make it into something for Halloween - thus it's a little bit messy and rushed.

The unminified source is at the bottom of this post in a spoiler - it's too big to make into a cart without minification. Even after minifying, I did run out of space: v1.0.1 takes up 99.8% of the compressed cart size(!).

General Notes

Sprite sheets

There are 3 sprite sheets:

  • "game" the built-in PICO-8 one which has the kittens, the breakable objects, candles and monsters.
  • "house" the map tiles for the house background
  • "title" the letters for the intro titles

The latter two are encoded in "dbi" format - i.e. the output of my Python image downsampling and compression code (dbi=="drake blue image"; I needed a name of some sort...). This will encode 4 bit PICO-8 images as 1,2 or 3 bit data if few enough colours are used, apply a couple of run length encoding schemes and encode the smallest result as 8 bit unicode for pasting into source code as a string. I wrote it for my attempt at a Dungeon Master clone at the end of last year and tweaked it since then (one day I'll finish that game too). The PICO-8 code for it unpacks this format to lua memory as a table with palette and image data. Once unpacked, the palette for the image can be set by a simple pal call, the data by using poke4(dest,unpack(data)) - very simple and, surprisingly, faster than a memcpy. I tried unpacking to the "upper memory" above 0x8000, but it was slower.

I drew the letters sheet using only 8 colours for the Christmas game which lets that image be encoded as 3 bits per pixel. I think I could have used 4 colours (i.e. 2 bit) and it would have looked fine for this game and saved up to a third of the data size.

At the end of the project I found that I'd run over the compressed size limit, but also that I hadn't used all of these two extra sprite sheets. I cropped them to the portions I was using, re-encoded and that was enough to get under the bar no code changes necessary :)

Editor

I knew I would use a separate sprite sheet for the house graphics (as opposed to the characters, decorations) so I began by making the house in a separate cart. I started off using PICO-8's sprite and map editor, but I swapped the latter for Tiled using the plugin here. This worked very well. I use Aseprite for most sprite work, but for some reason I did all drawing in PICO-8 for this game.

For the last game I'd generated the platforms by hand: add some values, run, look at a debug rectangle, repeat. That was okay for one Christmas tree, but didn't appeal for a whole house. I considered having no separate platforms and using impassable tiles, but having experimented a little with drawing the house interior already I was having enough trouble making it look as nice as I wanted without adding any more limitations. Besides, I wanted to see if it would work "off-grid".
I was already working in a separate cart to the game so I started adding code there for editing where the platforms and walls went. Then I added a simple ball sprite in position 0 (so it wouldn't be drawn by the map) so I could test the platforms. I considered adding the kitten code and encoding their graphics for it, but never got round to it.

Eventually I moved more and more into the editor as, even though it is clunky, it's still easier to work with for me than entering numbers by hand.

I liked adding the rectfill areas that paint the walls so much that I used that to draw the "paintings" instead of using more sprites. I considered adding a bunch of shadows this way, but ran out of time/patience.
PICO-8 draws rectangles so fast that this didn't seem to dent performance at all.

In retrospect, I would have liked to do one of two things:

  1. implement the editor in another environment eg. Love2D

Primarily so I could take advantage of a bigger resolution window and make the interface a bit nicer.
Incidentally, I did make a double display version of the game in PICO-8 very early on so that the two kittens could play split-screen. It worked very well, but I couldn't get the html output to work nicely with the two displays, despite a few attempted hacks (I hate web-programming) so I parked it. Might have another look at that soon especially if someone can help me hack the css to display it nicely.

  1. make the editor and game one cart

Getting the platform data to save so that it could be used by the editor and the game was a bit annoying. To begin with I used printh to output to console then copied and pasted into the editor and game code separately. Yep, pretty annoying.
I worked out that I could printh to a file and then #include that file from both carts. Problem solved! Except PICO-8 didn't seem to like writing to a lua file that already existed (even though I told it to) and wrote out a .p8l file instead. I'd rename the file back to .lua to update the data. Annoying.
So I wrote a little bash script to run between saves. Less annoying.
It's kinda funny, but I only just worked out I could import the p8l file, instead of .lua and it would Just Work. Ah well, next time...
This has also made me wonder about making user-definable levels for a future game...

The big problem with putting the editor in the game would be that the editor functions obviously use tokens. It's another reason (along with test and debug code) that I would appreciate a "dev mode" in PICO-8 that blocked exporting to png, html, bin etc. but would work from .p8 files during dev time. Even if it put in a "dev mode only" banner or "over token limit" that flashes up every ten seconds or something when run like that...

Anyway, here's the editor if you're interested, with data baked in so it runs - it will still output, I guess, but I don't think it will update to use the new data. I've not tested it on here much at all and be warned: it's really not intended for use by anyone but me and even I could barely use it.

X shows platforms, walls, floors and highlights current selection for those (and the "paints").
N shows monsters, candles, dec(orations).
There's a bunch of other obscure key commands.

Worst bit: delete (-) has no "are you sure?" and there's no undo.

Interface weirdness aside, it's still been a much nicer way of working than typing the code in by hand so I would definitely use this approach again.

Initialisation

I pull in the two "extra" sprite sheets first ("house", "title") then store the cart's one ("game") so I can restore it from lua memory when needed. There's a few palettes for fading to black, lightning and the darker palette that's used for most of the game.

Because the game never really restarts and when you finish it the cart is just run again, the state of the music is pulled in from one of the stat values. This is the downside of that approach. The upside is that there's no need to write a reset routine and test it. It's worked okay for other game for me.

Writing this post has made me remember that switching the storm off doesn't survive restarting the game so maybe I should fix that if I find space in future.

Most of the rest is run of the mill initialising of variables and tables, except for setting up the majority of the entities in the game: the platforms, monsters, items etc.

During this project I wrote about how I was processing data stored in strings into tables: see here. I improved this a few times, but it always relied on feeding to the same constructor function that meant every entity had the same elements: x,y,r,b,c (if I remember correctly).
x and y were fine - position. But r and b (right, bottom), for instance, only made sense for the platforms and meant different things for, um, different things e.g. velocity for the bats.

I wanted to change that so I considered different constructor functions and triggering those depending on the data - that might have worked, but they'd have cost a lot of tokens and I would have needed to put those functions in a table (or mess about with _ENV) anyway and it occurred to me that I could implement what's now in the code:

function unpack_data(raw_data)
 local raw_data=split(raw_data)
 local num_elements,data,names,item=raw_data[1],{},{},{}
 for p=2,num_elements+2 do
  add(names,raw_data[p])
 end
 for p=num_elements+2,#raw_data do
  item[names[(p-2)%num_elements+1]]=raw_data[p]
  if p%num_elements==1 then
   add(data,item)
   item={}
  end
 end
 return data
end

This lets me describe and initialise a table of tables (or entities as I think of them) with the element names that I want like so:

g_things=unpack_data'5,x,y,vx,vy,col,10,10,0,0,12,20,20,0,0,11'

The first value is the number of elements for each item, then a list of the element names and then the values themselves; for two items in this case. Add more entities by adding more numbers to the end of the string. It works for string values too of course.
That line costs 5 tokens and each table subsequently costs 4 more if you put them on the same line. You can see that the vx, and vy values burn a lot of characters - there's nothing to stop you adding those values later. I needed those elements to be non-nil so I put them in there. I might try adding them later if I need to extend the game as I'm in the weird position where I've run out of space before tokens. Of course, this string data, and the encoded images, are probably why it's got like that.

Having an editor to automatically output the large strings involved in this approach is quite helpful.

I guess the next step may be to encode the values as unicode (assuming they fit in a byte or two) to save even more space, but I haven't tried that yet and I don't know how the PICO-8 compression would react; it might not result in much of a saving.

Game modes, _draw and _update

There are three game modes: title, start and play. I re-used a set_fade function to move between these which deals with fading the palette in and out and changing the mode. You can pass it various functions and arguments to execute as soon as it's called, when it's faded to black and when it's faded up. I think. I can't remember how it works, but it seems to do what I want it to...

As with most of my carts, in the _update and _draw functions there are a few things that get done every frame, whatever the mode.
_update60: pulse and fr variables that control animation and periodic effects. I've used these since P8C-BUN, they work very well for little PICO-8 games (when trying to write bigger things e.g. using Love2D they don't and they are a pain to remove, but that's a whole different story).

Screen shake is updated here as well, inline since there's no need to call it in a function (and some token-saving habits are hard to shake ;) ):

-- update_ss()
 g_ss.x+=g_ss.vx
 g_ss.y+=g_ss.vy

 g_ss.r,g_ss.b=g_ss.vx*0.6-g_ss.x/5,g_ss.vy*0.6-g_ss.y/5
 if abs(g_ss.vx)+abs(g_ss.vy)<0.1 then
  g_ss.x,g_ss.y=0,0
 end

There's no real reason not to make this separate variables instead of a table (g_ss_s vs g_ss.vx), but I never needed to do it. The conditional at the end of this snippet makes sure that the camera doesn't get "stuck" slightly off centre.
My "cam" function that wraps the PICO=8 camera() native function adds the screen shake values any time I change drawing origin and ensure that everything shakes.
There's a "shake" function that actually kicks it off.

Then it calls whatever update function is currently set.

_draw()
This resets the palette and camera and calls the current draw function. It also does the lightning - which is the same in every mode.
Randomly, a lightning strike is triggered, which consists of the screen being cleared to white, sfx triggered and countdown set. For each frame the countdown hasn't reached zero, the screen palette is set to a pre-determined set of lighter colours. Very simple, but works quite nicely. Looking at it now, I'm tempted to see if I could make the lightning fade more gradual by having more stages. I could feed the palette through the lighter map more than once, just like how the fade to black works or set up a table with gradually lighter palettes.

Most of the time, the palette is darkened to make the lightning more of a contrast and attempt to give the game a slightly more spooky atmosphere. Yellow is the exception to this (the orange is fairly bright too) so I had to be careful where I used that - it's supposed to highlight the candles that the kittens need to find and make the monster's eyes (and the pumpkin) a bit more scary.

In the menu, you can switch the storm off and that restores the normal palette and stops the lightning.

Title

As mentioned above, I started with the DtCT code and was writing a Christmas game, so for ages this section was untouched from that. When I embarked on the Halloween project this was the first thing I played with though.

Snow to rain

I altered the snow code to update multiple times per iteration. This makes two things happen: the raindrops appear to fall faster and makes them appear to be elongated. I tweaked the number of drops to make sure that it still ran fast enough and noticed that they were getting "caught" on the letters to the extent that the rain appeared to stop. So I hijacked the "simpler snow" (which also became rain) I'd added to the play game mode to fall constantly in the background and not interact with the letters. Speeding up the letters moving helps to hide this problem too.

Titles

There are some pal calls to make the letters a more spooky colour - I didn't change the image asset at all apart from making a K into an H and the dots on the 'i's into skulls.
For ages it still talked about Christmas after that until I could face updating the title data to be the right words...
For the previous game I'd entered this all by hand with a lot of trial and error, but having used an editor for the rest of the game I couldn't be bothered doing it by hand again. I also couldn't be bothered adding all the code to my editor that I'd need to draw the titles so instead I added it straight into the game mode and commented out the lines that move the titles about. It's pretty crude, but got the job done far faster than doing it by hand.

The code is still there, commented out.

This mode also uses the screen fade routine with one of the variants described here for added wibbliness. This is the same effect as used in PICO Space.

Start

I pulled in the simpler rain code and screen fade for this screen too. Writing text and getting it to fit on the screen takes ages - I really should find a nicer way to edit it e.g. in PICO-8 itself. P8SCII means that the whole description is a single string. I added the control descriptions, ghosts and kitten heads at the end when I knew I wasn't short of tokens.

Play

I implemented this constantly watching out for the moment when performance would drop enough that I'd need to do some optimisation, most likely to draw/update portions of the house at a time, instead of just updating and drawing everything every frame.
I considered various strategies to bucket entities, update on alternating frames etc.

The moment never came. The game draws and updates everything, every single frame and only rarely breaks 90% CPU, even now I stopped worrying about it.

I was disappointed and relieved at the same time :)

Update

  • move enemies: note the pumpkin and the skulls are all considered to be pumpkins. I probably didn't need to do that in the end, but that's the way it is.
  • move kittens and check how they're interacting with platforms, floors etc.
    -- platforms are only impassible from above if the player isn't pushing down 'Mario'-style (I think, never played Mario much as I never had a Nintendo as a kid).
    -- floors are impassible from above and below
    -- walls are impassible from left or right
    There are many, many platforms and not many floors or walls
  • check if kittens have hit anything with their bops and react
    -- spawns some particles
    -- converts decorations to "fallers"
    I've just noticed I still have some of the bonus code in there even though it isn't used in this game...

Also, you can see where I hacked the collision routine for the kittens (in_rect) with an unexpected "+8" because for some reason the kittens are drawn 8 pixels lower than you'd expect and I had to add that to make the collisions with the monsters work(!).

Draw

The trickiest bit of this was deciding when to swap between the house and game sprites. In the end it uses something like the following sequence, starting with the house sprites loaded into PICO-8 sprite memory:

  • draw background
  • load game sprites
  • draw decorations, candles
  • draw monsters
  • draw kittens
  • draw HUD
  • load house sprites
  • draw stairs and parts of doorways in foreground

This means there's only two loads, mid-frame. If you look closely you can see that the scores go behind the stairs, but to fix that I'd need two more loads and it'd never run at 60fps. Maybe for Picotron...

When the game ends, I use the title sprites for the "Happy Halloween" message so they need to be loaded in and that pushes the CPU just over the 60fps limit into 30fps too :( It's not too bad - you can still run about the house okay, I think - and I didn't have time to fix it. I'm not sure that I even can.

Conclusion

On the whole it works and people seem to like it. I could improve the code a lot and if I could work out a way to save compressed size and take advantage of the spare tokens I suspect I could add some more - maybe more options for more varied gameplay would be nice. I think I need to work on gameplay and prototyping that earlier and worry less about coding, squeezing in assets and graphics until I have that a bit more "down".

The editor worked really well and I was pleased with the data (un)packing functions.

Now I have to decide if I still want to make the Christmas game with the kittens and how I could make it better. I guess I could mahe the house/playing area even bigger. Only the background graphics are restricted by the map grid - just saying...

Unminified Code

Warning: this is pretty messy and not v efficient. I haven't really done any token optimisation on it at all.
If you have any questions about it, please comment and we can puzzle out what on earth it does together :)

I would help with JS and CSS to make the wide web version!
I’m on pico8 discord.

P#99532 2021-11-03 01:11

Ah, sorry merwok, just saw this.

I had a look at how far I'd got with the double screen version. I'd been able to hack it to work okayish on desktop, but I gave up when it came to the mobile version and touch controls etc.

I might have another go, but I have to confess that one of the reasons I like using PICO-8 is specifically because I don't have to do any web programming...

Changes I tried are in the spoiler:


After exporting to html like normal in PICO-8, enabling the second display to be viewed just needed a line in the html:

    Module = {};
    Module.canvas = canvas;
->   Module.arguments = ["-displays_x","2","-displays_y","2"];

That bit's okay. Its the next bit I don't think is very good: I hacked a couple of other values

        canvas.style.width = csize;
        canvas.style.height = csize;

to

        canvas.style.width = csize*1.5;
        canvas.style.height = csize*1.5;

and

->           margin_left = (frame_width - csize)/2;

            if (p8_touch_detected)
            {
                if (window.innerWidth < window.innerHeight)
                {
                    // portrait: keep at y=40 (avoid rounded top corners / camera nub thing etc.)
                    margin_top = Math.min(40, frame_height - csize);
                }
                else
                {
                    // landscape: put a little above vertical center
                    margin_top = (frame_height - csize)/4;
                }
            }
            else{
                // non-touch: center vertically
->               margin_top = (frame_height - csize)/2;

to

->           margin_left = (frame_width - csize*1.5)/2;

            if (p8_touch_detected)
            {
                if (window.innerWidth < window.innerHeight)
                {
                    // portrait: keep at y=40 (avoid rounded top corners / camera nub thing etc.)
                    margin_top = Math.min(40, frame_height - csize);
                }
                else
                {
                    // landscape: put a little above vertical center
                    margin_top = (frame_height - csize)/4;
                }
            }
            else{
                // non-touch: center vertically
->               margin_top = (frame_height - csize*0.75)/2;

Then I gave up.

Can you share the cart with multi-display?

P#99744 2021-11-07 18:30

This is as far as I got:

Cart #db_multi_xmas2-0 | 2021-11-08 | Code ▽ | Embed ▽ | License: CC4-BY-NC-SA

It won't work as multi-display if clicked here. It's also pretty broken and is still Christmas-themed, but you get the idea.

These args are needed to launch pico8 with the desired layout (same as in the html changes in my last reply)
-displays_x 2 -displays_y 1

If I get the chance I might work a bit on getting the Halloween game working with split screen.

P#99788 2021-11-08 17:04

Just realised that 0.2.3 isn't letting multi-display be enabled in HTML exports. It did work in 0.2.2b and I'm hopeful it will be re-enabled in a coming update.
