Hi, quick question.

Does anyone know if there is a limit to how many leaderboards can be created for a cart?
Documentation says scoresub() only returns the top 64 scores, but is there a limit for how many leaderboards can be made? Or can i just keep making new ones?

I assume only @zep would know, but maybe someone has the inside scoop?

Hi, new here. I'm trying to figure out how to handle collisions for a 16x16 player sprite with 8x8 map tiles with flags. I followed this SpaceCat tutorial https://www.youtube.com/watch?v=oBzmFxG2ezM.

Some edges do collide correctly and prevent the player (blue square) from crossing the map tile (green square) with flag set, but some edges don't and blue can cross over green.

I put together a very basic sample cart (and hopefully uploaded it correctly).

Can someone tell me what I'm doing wrong? Am I missing some math for the 16x16 sprite dimensions?

Thanks!

Call of Pico: Survivors!

Survive as long as you can
Kill enemies for points
Use points to buy perks and unlock new areas

controls:
🅾️ = shoot
❎ = interact
❎ + ⬅️ / ➡️ = switch weapon
❎ + 🅾️ = pause

I basically tried to make a fusion game of Call of Duty: Zombies and Vampire Survivors.

Pretty much my first game so there's probably tons of jank.

Im the only person that actually play tested this, so feedback is much appreciated

How far are you guys getting? Does the difficulty spike too fast?
Are you able to find the other weapons? Should I leave more tips or hints?

---------------Spoilers for Game--------------

--EE Steps--
--Get 4 new weapons by getting kills near weapon crates
--active teleporters by getting all weapons
--teleport to get soul keys in uwu room
--unlock doors with soul keys
--locked doors give either:
-- 1 more perk slot (up to 4),
-- parts to upgrade uwu (up to 4),
-- parts to increase perk level (4 parts for +1),
-- parts to craft wonder weapon
-- 4 perk slots can be unlocked by shooting 4 cracked tiles with wonder weapon
-- lvl 5 perks unlocked by shooting active box with lvl 3 weapon and 12, lvl 4 perks
--Final Step--
--after all weapons are lvl 3, use uwu to activate final step
--zombie spawn rate is increased and round does not increase
--interact with all weapon crates to level up uwu to teleporter
--interacting with the uwu teleports the player and finishes the game

What better way to get back on track than by making a little game? In "DIAMS ! DIAMS ! DIAMS !", you destroy monsters by matching groups of three of the same color. Every third monster earns you diamonds—both for itself and for any others it takes down with it. If you play without making mistakes, the number of diamonds earned per group of three increases. A good color combo also grants a lucrative bonus to help you smash the high score. The current house record is 42,182 points. I hope you have fun!

Preface

Last night I was gripped by the urge to make a tline() based map renderer so I could make cool distortions. I ended up finishing it after a couple hours of research and hacking, and I felt it was a good thing to write about.
This is going to be one of those tutorials where all the steps are explained. If you just want the final code, I won't judge, just scroll down and grab the demo cart, it should be well-commented and easy to pick apart.

Method

The specific way we're going to render the map with tline() is by defining the viewport with 4 points on a quadrilateral and rendering each column of the screen individually. We sample 128 points along the bottom and top lines using tline and draw those to the screen. This is actually the only rendering trick you need to pull off, all effects based on this just depend on how you move the four points!

TUTORIAL START

Defining Our Points

function _init()
	toplx1=0
	toplx2=128
	toply1=0
	toply2=128

objective

In "blob jump" you are a blob that can jump, you need to get the coin in every level while avoiding the spikes

lessons learned

Okey so I wanted to practice a few things but not create a ton of levels... this are just two levels, but I got to

  • Practice platforms collisions
  • Gravity and more advanced movement

I got a ton of inspiration for achieving this things from:

Second game from Dylan Bennet's zine, uploaded here to test the process of sharing games (and to celebrate success :D). I took the opportunity to mess around with particles since I never programmed particles myself.

Cooking up some mad wizardry on this.

3D + subscore() multiplayer is gonna go HARD! Wish me luck!

This is a reworked version of my first go at making Scoundrel in Pico-8

[First Scoundrel Game]

  • I have fixed the rules so that it follows the correct rule set from the original physical game.
  • I have also added 2 new styles to the game to play.

[ UPDATES ]

1.1

  • [NEW] Game resets to the last mode played in the menu after losing a game

1.2

  • [FIXED] The UI cursor would highlight hidden options by mistake when your hand was less than 4 cards or you avoided a room.
  • [FIXED] When playing HOUSE rules cards would display the sword is dull message on cards that could still be attacked by mistake

This is a simple little game I made for a short jam with a theme of "If you can't see it, it doesn't exist".
Decided to keep it simple with a one-button single screen game.

Sporting equipment is coming at you, but it can only hit you if you can see it: Hold (X) to blink while things go through you.
Your score increases while your eyes are open, and will decay if you keep them closed for long.
Things get harder as you reach certain score thresholds - More frequent and varying objects! Harsher score decay (but also faster score increase)!

I have been playing around with this idea for a while. It's fun to paint around and watch the pretty dots move. Or to find seeds of complex behavior. Lots of room for optimization or additional features. Much credit to John Conway.
