Press X to jump.
Rules
You must start your jump before the foul line and then jump two more times before landing in the sand pit. Running across the foul line, in between jumps, or into the sand pit will result in a foul.

Hello, I need some help with an error that I have been encountering in my code. I started coding a few days ago but I have been working on someone else's game. For some weird reason when I call cartdata() in the init function and later in the update60() function I get a error "DGET CALLED BEFORE CARTDATA() IN _INIT LINE 287 (TAB 0) AT LINE 1 (TAB 3) you can see it for yourself if you run the game and chose "TIMED" and collect 25 flowers.

The cartdata() function is in init so I do not get why the error is occuring.

RAIDOUZ
Raidouz is a really simple shoot-em-up type game, you can shoot, you can upgrade and you can even change weapon, but for now not everything is balanced as all things should be. It is a work in progress ! There is still some little bugs but the game is playable and you can get fun with it !
Controls
Z to shoot.
X to change between two weapons.
Arrow keys to move.
The Goal
Have fun, kill everyone and try to score as much as possible !

Welcome to Elite for the Pico-8 home console!
This game is intended to be less grindy and slow version of the NES Elite, suited more for an evening of fun rather than a week of space-trucking. If you're wondering how to play, I've written a Game Manual
Before you play: Holding down the (X) button and pressing Left or Right is how you navigate menus. Double-tap (X) to select a menu option.

A short little game about eavesdropping on conversations in the park.
Thanks to my partner for contributing dialogue, and NerdyTeachers for the tutorial on text animations that sparked the idea.

Basically, I’m working on a digging game and am revisiting something I have worked with in the past: marching squares. I recommend looking it up, but basically the way it works in this project is for each “tile” a table of tables is examined and depending on whether each of the tiles coordinates are on or off the algorithm figure out which sides does the line on the square intersect. Sometime marching squares also uses linear interpolation, but since my screen is stored in binary instead of floating point values I am storing intersection points in separate nested tables. The main thing is that each square is checked, and depending on stored values a specific line might be drawn through it.

I made this tool for myself, for reordering levels to fix difficulty curves. But I thought I'd share it in case anyone else finds it useful.
How it works:
- Press X to select a room, and then X again to swap the two rooms
- Press C to preview a room
- Maps are imported/exported manually using
cstore. Cry about it :(
Note: Mapshuffle cannot import/export maps in the web player. You must download the cart and use it in immediate mode.
Instructions:
- Back up your project in case something goes wrong.
- Download mapshuffle.p8 and place the cart in the same folder as your project.
- Open your project, type the following line into the terminal, and hit enter:

people often ask about object orientation (OOP) and inheritance, but can get confusing or incomplete guides. I want to help everyone understand how prototypes work!
lua does support object-oriented programming (but does not require it), based on prototype inheritance — not classes.
metatables are part of this but also often misunderstood. this is a complete explainer that I wrote on discord and keep not putting here in a clean way. so I am putting it here as it is!
so what is a prototype?
goblin={
sp=42,
}
function goblin:new(x,y)
local obj={x=x, y=y}
return setmetatable(obj, {__index=self})
end
function goblin:draw()
spr(self.sp,self.x,self.y)
end
gob1=goblin:new(40,40)
gob2=goblin:new(60,70) |
alright so this is like 6 different things working together.
1) table with methods: goblin is a table with property sp and methods new and draw (a method is a function attached to an object)
calling goblin:new(40,40) is the same as goblin.new(self,40,40); self is «the object we are working on»; defining function goblin:draw() is the same as function goblin.draw(self) and the same as goblin={sp=42, draw=function(self) spr(...) end, somethingelse=true}
there is a difference between the two methods in my example: when we call goblin:new, the self param inside it will be the goblin table itself (the prototype), but when we have gob1:draw() then self inside draw will refer to gob1.
2) metatables. there are special methods that lua uses to implement operators (+, /, .., etc). the method for addition for example is __add (we call these metamethods). if I want to be able to do vector1 + vector2for my custom vector tables for example, I need to define a method named __add but I can’t do it in the vector prototype table, lua will not look it there; it is required to define these metamethods in a table’s metatable. (the metatable is similar to a class in other object-oriented languages: it is the template, or the definition, or the model for many tables.) so that’s what happens in goblin:new: I define a metatable with one metamethod and set it on my goblin object.
3) prototype. these are great! if I have 50 goblins on screen and they have different health and coordinates but the same properties for sprite, width, height, etc, and the same methods for update, attack, draw, etc, I would like to define all the shared things in one place, then have custom things in each goblin table. that’s what a prototype is for! here in goblin example we have sp and draw shared, and in a specific goblin table (it starts as obj on line 6, then it’s gob1 or gob2 in my example) we have specific data like x and y.
much more info on this really useful site: https://gameprogrammingpatterns.com/prototype.html
alright so how do I say «gob1 and gob2 should delegate to goblin prototype for some properties»? I define a metatable with an __index property. it is called by lua when I do gob1.sp and sp is not found inside gob1. it can be a function (can be useful to have a dynamic property that’s computed from other properties) or another table: the prototype!
more: https://www.lua.org/pil/13.4.1.html
now this is the cool thing with prototype-based object-oriented language that you don’t have in such a nice way with class-based OO languages
what if I want 40 goblins on screen and 10 archer goblins? these should have a different sprite and different attack method.
archer=goblin:new() archer.sp=52 function archer:attack(target) --use the bow end arcgob1=archer:new(20,50) arcgob2=archer:new(40,70) |
look at this from bottom to top:
arcgob1.xwill be 20,y50- arcgob1’s and arcgob2’s prototype is
archer, because when we callarcher:new,selfon line 6 of my first code block points toarcher arcgob1.spis 52 (the value comes from the prototype)arcgob1:attack(hero)will use ourarcher:attackmethod.arcgob1:draw()will usegoblin:draw! archer itself is a table that has goblin for prototype
drawis not found in arcgob1, look at its prototype archer, not found, look at its prototype goblin, found! call it withselfpointing to arcgob1.

n-back (Wikipedia, Gwern)
How to play:
1-Back: Remember whether the position or color (or both) is the same as in the previous round, press the according button/buttons if they match.
2-Back: Remember whether position or color are the same as 2 rounds ago.
N-back: Remember whether position or color are the same as n rounds ago.
Controls:
Z or <- for a position match
X or -> for a color match
P to pause (+ additional menu)
Tips:
Try playing in standard mode to understand how the game works, in endless the game ends when you make a mistake or miss a match.

Cascade Cascade
A game somewhere in the space between a breakout clone and a puzzle bobble clone, inspired by a half-remembered game I played on an airplane seatback.
Controls
- Aim with left and right arrows
- Press [x] to fire
Or, as of 2024.04.27, point and click with the mouse to aim and fire.
Rules
This is an endless arcade game. Your goal is to survive by keeping the blocks from reaching the bottom.
- Each hit reduces a block's strength by one. When a block's strength reaches zero, it's destroyed.
- Powerups (white concentric circles) increase the number of balls you can accumulate for your next shot.
- The number of balls you'll fire next shot is indicated by the combo meter on the right side of the screen. It increases by one-half for each block you hit.
