After over a year of working on my own 3D graphics engine and my own 3D modeller for it, I threw this together in a day just to have finally made a "game" with the engine after all this time.

avoid rocks, shoot for points
star worth more points if shot rather than collected by the ship

this is really rough but again its made in a day, I plan to use this as a kind of starting point for a semi-ambitious racing game I have a ton of ideas for, so look forward to that in a loooong time
sorry if there are any bugs!

also credit to p01 for the trifill I'm using

Taking care of a pet rock can be very hard, in this simulation game,
take care of your pet rock thats constantly getting into trouble
and getting dirty!
dont let it get too dirty by shaking it off every few seconds,
if it gets too dirty, your rock may disintegrate,
and thats game over for you. Have fun playing this pet
rock simulator!

[this probably isn't a bug but I don't know where would be a better place to post it to]
I just downloaded pico-8 but I can't get it to work. Or, basically, I can get it to open, but it automatically opens as fullscreen [which I don't want] and then I can't exist fullscreen or quit the app. I had to turn off my computer to get out of the app. I can't use "alt+enter" to toggle fullscreen because my keyboard doesn't have "alt+enter", it has option (same as alt) but enter? what button should I press instead? will "option+return" work on mac? or can I change what the keyboard shortcut is somewhere without opening the app?
Also, "ctrl-Q" was not working for some reason, I couldn't quit the app that way, which is worrying because "ctrl-Q" should have worked since I have those buttons on the keyboard. "escape" did work to toggle between the viewscreens in pico-8 which is apparently what it's set to do, however, I will say it might be nice if it actually let you get out of the app... surely there's another key command that could be used to toggle, so that you can actually use esc to get out?????
There's definitely no way I'll want to open the app if I can't even get out of fullscreen or quit it...

Hi,

I have noticed an issue in some carts that if I switch between keyboard and mouse, then the keyboard no longer works correctly. In particular the cart "Dungeons & Diagrams PICO-8 Demake" by @choo-t ( https://www.lexaloffle.com/bbs/?pid=dungeons_and_diagrams-5 )

If you start it up and use the keys, you can move around the grid. As soon as you use the mouse to move, the arrow keys stop working. The work-around is to click on the browser tab, or the PICO-8 Window Title bar and then the keys start working again.

Running on Windows 10

Technical Notes


This game uses P9 Compression to have four banks of 16x128 tiles that can be switched between during gameplay.
[128x32]

Each level is then defined as an array of "blocks", where each block is a rectangle of the tilemap somewhere in the level. This allows me to have seven different areas, some of which are quite large, as well as easily having overlapping elements. Blocks can also have properties such as an update method ran each frame, if they should have collision disabled, if they should be drawn in front of the player, if they should be drawn just as a cheap rect fill, if they should be repeated etc. This gives me a lot of power in level design.

The physics is relatively simple, with the character animations being based on a very simple spring math:

spring_dy = (spring_y - spring_y_target) * SPRING_CONSTANT 
spring_dy *= (1-DAMPING_CONSTANT)
spring_y += spring_dy

Each level uses a different screen pallete, which often use the secret palette. Additionally for the title screen, a (trick)[https://www.lexaloffle.com/bbs/?tid=38565] documented by @BoneVolt is used to switch to a different pallete for the area of the screen behind the logo! I had to do some extra bit of bit math to have it drawn to an arbitrary place on the screen without clobbering memory!

 y= 10 -- The vertical position in PIXELS
 h= 3 -- The height in rows of EIGHT pixels
 poke(0x5f5f,0x10) -- enable the effect
 pal(NEW_PAL,2) -- Set the pallete for the section
 pal_memset(0x5f70,0,16) -- clear the settings from previous update
 local rem=flr(y)%8 -- calculate the remainder, since the dual-pallete mode works rows of 8 at a pixels at a time
 pal_memset(0x5f70+(y)/8-1,255<<rem,1) -- Set the flags above where main body made of full 8-high rows can be set
 pal_memset(0x5f70+(y)/8,255,h) --Set the flags for the main body of h 8-pixel-high rows
 pal_memset(0x5f70+(y)/8+h,~(255<<rem),1) -- Set the flags below where main body made of full 8-high rows can be set
function pal_memset(addr, val, len)
    if addr >= min_mem and (addr + len - 1) <= max_mem then
        memset(addr, val, len)
    end
end

Made in like 40 minutes for some reason. Actually made throughout one day when I was bored in school but I ended up losing the cart (as per my last post) and remaking it as fast as possible.
You can stand on the little dots inside the ground (for beatability purposes).

P.S. I generally don't like naming mods ___este but I had to.

I was making a game on pico-8-edu.com and when I saved it, everything appeared to work normally. But when I tried to open that cart again on the education edition, it said it couldn't fetch the cart. Luckily I had the cart open in another tab so I saved it as a .p8.png this time. The image wouldn't open either. I renamed the .p8 to a .txt and it showed as an empty txt file. It also says both the .p8 and the .p8.png are 0 bytes. I need to restart my chromebook tomorrow so how can I save my cart (obviously without leaving the tab open)? I really don't want to lose the game, I've put a lot of hard work into it.

A simple game made in two hours about a bat who hates fruit!!
The only fruit it'll eat is dragonfruit and watermelon.
Watermelon slows time down to make it easier to navigate,
dragonfruit gives you an extra life

I've written a small game about fitting a block through a gap. The smaller the gap the better the score. Left/right buttons move the left paddle in that direction and the right in the opposite direction. The Z button drops the block and you can also use the X button to pause the game but I might remove this. The block reduces in size each time you are successful and the game speeds up once you get through all size of block.

I'd like to add menus, a level select with how well you've done in each level and maybe some music.

Behind the Scenes

This is my basic shmup game, I was going to make it more elaborate, having my original design being "Bayonetta Dodonpachi" but after coming across a bug with the lazer I gave up on the project. I wasn't satisfied with this so I decided to cut the stuff that wasn't functional or working and decided to post this online, maybe you can take this and make something better than I did! I am just glad that it is "Finished"

Hello! I've made a cart on my console and it runs there. But when I upload it onto BBS, it gives a syntax error.

Error:
syntax error line 5 (tab 1)
-return fget(mget(x/8,y/8),f)
<eof> expected near 'end'

Function:

function gfap(x,y,f)
-return fget(mget(x/8,y/8),f)
end

i've marked indent spaces as '-'
