There's nobody else like me. I checked.

This is a quick port of my PICO-8 boids cart. Nothing fancy, just some boids doing their thing.

I've been wanting to do this for a while. This is a simple boids simulation. Most of the code was adapted from Daniel Shiffman's implementation in Processing.

Feel free to pick apart the code. Unfortunately, it's not commented much, and I'm absolutely sure there are optimizations that can be done.

This is a heavily commented cart that shows one way of doing flowing dialog text with coroutines. If you have any questions on how it works, feel free to ask. Again, this is one way of doing it. :)

I just finished creating a tutorial for making a top-down adventure game in PICO-8. It's 10 relatively short videos (45 minutes for all 10 videos). You don't need any prior experience with PICO-8 to do the tutorial. I have done this tutorial with many, many kids and the games they create with it are always inspiring.

UPDATE 8/25: I've added a bonus step that allows you to add text to your game! :D

UPDATE 8/27: I added another bonus step that allows you have as many types of tiles as you want. You could use them for treasure, special keys to specific doors, teleporters, quest items, anything you want! πŸ—οΈπŸ“œ

You can find it on itch.io and on YouTube:

If you have any questions or need any help, feel free to let me know. I hope you enjoy it! :)

My Happy Challah Days entry for the 2018 PICO-8 Advent Calendar was created using this tutorial as the base code. (I added extra features for the jam, like dialog boxes, quests, and a larger inventory, but its foundation is this tutorial.)

This was a slide deck I made for a mini workshop I gave on arcade mechanics at a PIGSquad Summer Slow Jams event last night. (Following in the footsteps of @nextlevelbanana, I used a Nintendo controller as a clicker. πŸ˜„) Feel free to use the code for your own presentations.

This is a VERY simple game for very young kids to edit. This was literally coded in an hour, so it's not optimized or super clean code or anything like that. It just works and is easy for kids to edit. :) It's intended for kids to edit the sprites, sounds, and game variables.

Enjoy! :)

WHAT TO EDIT

SPRITES

Player - Sprite 1 and 2 are the player sprite.

Pickups - There are two rows of pickups. The top row gets only little_points if they are picked up. The bottom row gets big_points if they are picked up.

Baddies - These are sprites 49 and 50 (bottom-left of sprite tab 0).

Stars - The 4 pixels in sprite 48 (bottom-left) define the star colors.

SOUNDS

Sound 0 - When a top row pickup gets picked up.

Sound 1 - When a bottom row pickup gets picked up.

Sound 2 - When the player hits a baddie.

VARIABLES

little_points - Points gotten from picking up a top-row pickup.

big_points - Points gotten from picking up a bottom-row pickup.

game_speed - How fast the overall game should go.

player_speed - How fast the player moves.

animation_speed - How fast the animations change.

seconds_between_pickups - Self-explanatory.

seconds_between_baddies - Self-explanatory.

sky_color - Self-explanatory.

number_of_stars - Self-explanatory.

@zep, I've been really curious about the water feature in Voxatron. I love how it looks and how it acts. It just looks and feels so satisfying. But I've had just a hell of a time finding good articles that give me any sort of clue on how to recreate it with any sort of decent performance. (Or even to look as good as yours.) There's the classic water ripple algorithm that so many articles refer back to. But running that on 128^2 voxels just kills performance. Any clues as to what direction to look in to do water the way you do it in Voxatron? Is it something that works well because it's done "natively", so to speak, but wouldn't necessarily work well within the Lua performance constraints of the custom scripting feature?

A very simple tweetcart, but with the code expanded to make it easier to understand what's happening. Enjoy!

This is a quick little cart to let you see the difference between the editor color palette and the palette available through code. I hope it's useful! :)

A small exploration game about a little being who has crash landed on a planet and needs to find how to get home. You find some waystones that look promising. If you could only find a way to activate them, maybe they'd help....

(Please know that this is game jam code, which means it's horrendous.)

EDIT: Added the insides of trees so they look cool when they clip off the edge of the screen, and also a label image.

I don't know if this is a bug or a debug feature? But when pressing the number 6 while in the designer, it zooms in super huge on the mouse. This is really distracting when coding because it'll flash up huge on the screen if you happen to hit a 6 while you type! πŸ˜† Maybe an option to disable that feature while editing code?

The vox_api.txt lists the last two optional arguments for draw_voxmap() as rotation then color. However, it's color first, then rotation.

@zep, I had a few questions about the config.txt settings. I tried searching through old posts, but couldn't find anything, so I thought I'd ask here. Most of the things I could figure out just from knowing what they do in PICO-8. But a few were still mysteries.

  • ff_version
  • dummy
  • super_sample
  • voxel_style
  • render_mode
  • exhibition_mode

This is a remake of a PICO-8 game I made for the 2018 Zero-Hour Game Jam! Find all the orbs before the time runs out!

Trying to figure out why the player looks so jittery. I'm having the camera follow the player, and the ground below looks fine as the player moves, but the player itself is super jittery. In the embedded player here it looks fine, but while running in the designer, it's super jittery.

This was a game jam made for the PIGSquad Summer Slow Jams. Unfortunately, I started at 1:00am the night before the end of the jam. I worked until 3am until I couldn't do math anymore, then picked it up the next morning and put in another 3 hours to get it done before the end of the jam. So... uh... excuse the code. It's game jam code. :)

Pop Shot! is a 4-player arena brawler where you eliminate your opponents by charging up shots and using them to knock your opponents into the spikes. You have 3 lives, and if you lose them all, you turn into a floating skull. While you're a skull, though, you can mash the X button to float just a teensy bit faster. If your skull hits the planet, you get an extra life and respawn! (The creative theme for the jam was "The World Is Alive", so in this game, "The World Is A Life".) 😆

I am horrendous at music, so all credit for the music goes to @Gruber who makes fantastic tunes for all of us to use in our games. 😊
