Hello, I have this code that circles an object around the player position.

It works well if the player stands still, but if the player moves the trajectory of the object goes a bit wonky. it sort of stops, or looks like it wants to go in the other direction for a bit.

How can I make it smoothly rotate around the player?

    local player = self.game_context.player
    local orbit_radius = 40  -- Distance from player to orbiting projectile
    local orbit_speed = self.speed  -- Normalized speed of orbit; consider this as fraction of a circle per frame

    for p in all(self.projectiles) do
        p.angle += orbit_speed
        if (p.angle > 360) p.angle = 0
        p.x = player.x + (player.attributes.w / 2) + orbit_radius * cos(p.angle/360)
        p.y = player.y + (player.attributes.h / 2) + orbit_radius * sin(p.angle/360)
        -- Handle projectile duration and collision
        p.duration -= 1	
    end

SETTINGS REFERENCE

CELESTE CLASSIC GENETIC ALGORITHM [CCGA]
MOD BY ANTIBRAIN

[SETTINGS REFERENCE]

`FPS` : Simulation FPS. The timer in the corner will not be affected. 
You do not need to set it to a normal number. framerates like 22 and 46 are just fine.

`# OF PLAYERS` : How many players to simulate at once. 
More players means it will learn faster, but too many can lag the machine.

`CYCLE LEN` : How many cycles to run before selecting iteration to reproduce and grow.

`ADDED PER C` : How many FRAMES to add after every cycle SET. [after `cycle>max_cycle`]

`FALLBACK` : Min # of frames the ai is allowed to go back from preserved solution in the event of failure.

`MAX_H YSPD` : If enabled, MAX_HEIGHT will ONLY be updated if THIS.SPD.Y==0

`COIN REWARD` : Amount of points given for collecting a coin.

`BASE MUTATE` : The base mutate chance from 0-100%, without any deaths or changes. 
The mutate chance for each instance will never go below this number.

`SFX?` : Toggles sound effects that instances can make. (dashing, jumping, etc)

`MUSIC?` : Toggles music.

`SHOW N` : Toggles whether to display each player's instance number on itself. Enable to keep track of players.

`FLIP?` : Toggles whether to call flip() every frame to update the screen. When disabled, each frame will be updated instantly after the last frame. When disabled, It does break menus and cause a LOT of flickering, so use caution.

`IMPRV FALLBK` : Number of frames to wait after last improvement to try again from improvement.

`IMPRV MOD` : Number of frames to add after improvement fallback, to avoid an infinite loop. Can be disabled.

`MTATE KEEP` : Toggles if kept frames can be mutated.

`SEED RND?` : Toggles weather to seed the rnd function. Read below for info about modifying the seed.

NOTE THAT PAGE 5 SEED SETTINGS ARE ONLY AVAILABLE IF `SEED RND?` IS ENABLED.

`S` : Shows current seed.

`INC BY .1` : Increments or decrements seed by .1.

`INC BY 1` : Increments or decrements seed by 1.

`INC BY 10` : Increments or decrements seed by 10.

`DASH CHANCE` : % Chance for GA to decide to dash each frame. 10% by default.

`JUMP CHANCE` : % Chance for GA to decide to jump each frame. 10% by default.

`▤  PAGE X/Y  ▤` : Current page number. Left/right to view other pages.

Numbers can be changed with L/R. Booleans [TRUE/FALSE] can be changed with any button.

can you launch pico-8 on a raspberry pi via batocera? if so, con you launch it via ports and not emulate it?

The goal: Survive as long as you can.

Dev Notes:
It should be known that right now it’s only one level.
Mostly as a test bed before I wrap it all together with level generation.

There are bugs I am working out but the next up will be figuring out how to generate floors and so on.

--- Bug Fixes --

• Player health actually follows you between rooms!
• Boss battle instadeath

Thanks for checking it out <3

hello

This is my absolute first attempt at making anything 3d or 3d looking.

I want to learn the math behind 3d graphics in Pico 8, not the crazy ones, but the very simple ones, I am thinking of making a game kinda like in voxatron, with a static camera and a platform. I dont even want voxels, just 2d sprites. I tried using tline, and I just messed arount until it got to something.
I would be very happy if someone showed me any sources for basic Pico 8 3d, or cool things done with tline.

Thanks for checking this out :)

A Picotron port of Leonard Richardson's robotfindskitten.

Adapted from my PICO-8 version using pancelor's excellent p8x8.

Changes from the PICO-8 version:

• arena size embiggened to use Picotron's full resolution.
• everything is now rendered in the Picotron font
• you can now have up to 90 objects in a game
• the object descriptions removed from the PICO-8 version due to space constraints have been restored

This was mainly an exercise in trying out p8x8. It turns out p8x8 is really good and all the carts I tested with it went across smoothly. I recommend trying it out!

Made a tune:

Intermediate Celeste Classic mod.
Requires no tech.
May feature funny penguins and janky platforms, be warned.

v1.2 : Fixed a crash occuring when the player got crushed
v1.1 : Fixed an OOB glitch, added a secret penguin
v1.0 : Initial release

Hello,

I feel like I am being a bit thick this morning.

I have a 128 x 128 sprite sheet as a .png.

I've tried importpng and the pictron exporter from asesprite. both exhibit the same behaviour, when I paste from the clipboard the whole image fills sprite 0 and sets its size to 128 x 128, I'm expecting the image to start at sprite 0 and fill outwards. Am I missing something obvious?

thanks in advance

When Picotron was first released (around 0.1.0c) it seemingly just appeared in my Downloads/Updates page as a thing I could download, along with Voxatron, PICO-8, Chocolate Castle and others. I could download it just fine, and I continued to get new versions as they were released up until 0.1.0e.

At the time, I assumed this was intentional, perhaps because I'd purchased the Voxatron Debut Bundle way back in 2013. I believe there was a similar giveaway of the PICO-8 to who'd purchased Voxatron?

I understand now that Picotron just appearing on my Downloads page probably wasn't the intended behaviour of the website, and the Picotron should require a separate purchase to access, even for previous bundle/PICO-8 purchasers?

As of a couple weeks ago when version 0.1.0f was released, Picotron stopped appearing at all on my Downloads page.

I just wanted to check:

• Is it definitely intended behaviour that Picotron requires a separate purchase, and it wasn't given for free to anyone who'd previously purchased the Voxatron Debut Bundle or PICO-8?

Fun little project i hacked together on a weekend. It's my first "real" pico-8 cart.
Feedback and/or ideas are appreciated.

INTO THE INFINITUM

Hi there, hello! I'm Olórin, and Plasma-8 is my first attempt at creating a video game.

This game takes place in my science-fantasy, Horizon Nexus campaign setting; one of the many Realms in my tabletop RPG, Fable Spark. Our story begins when the evil Dr. Malicode conjures up a legion of awful pixel phantoms. From the bowels of the Super-Möbius galaxy, he now means to invade the Astraeus Beanstalk directly! What danger, what mayhem, what a whacky turn of events! Will you save this timeline from sure destruction, or will it be lost to the endless Infinitum?

Best score I've managed to get in testing is 1,284.

In pico-8, when I want to reuse a sprite sheet for a new cart, I would just
copy/paste all the gfx and map data at the end of the file. It's not so simple
in Picotron.

How do I start a new cart in Picotron with an existing sprite sheet and map?

I discovered the Pico-8 a few months ago, and have absolutely fallen in love with this project! I realize the intentions of the creator were to make a simple and comforting console for people to enjoy, but I can't help thinking that Lexaloffle doesn't really understand how important a Pico-16 would be to the gaming community as a whole.

Having the ability to create new games with slightly better capabilities would be absolutely game-changing (pun intended). I can just imagine how many designers would build amazing new games and even bring classic games back to life with a tasteful remaster. Unfortunately I don't think that would ever happen with a standard Pico-8, because the specs simply don't allow for this to happen. Don't get me wrong, I absolutely love the games that are available on the Pico-8 (as well as the limitations), but I can only imagine what a 16 bit version might look like! I think I speak for a lot of people when I say that a Pico 16 would make for the perfect fantasy console of all time!
