I'm new to PICO-8, and am trying to get a basic top-down movement system. So far I have this:

 
left = btn(⬅️)
right = btn(➡️)
up = btn(⬆️)
down = btn(⬇️)

xspd = (num(right) - num(left)) * player.speed
yspd = (num(down) - num(up)) * player.speed

if fget(player.x + xspd, player.y) == 0 then
	xspd = 0
end

if fget(player.x, player.y + yspd) == 0 then
	yspd = 0
end

player.x = player.x + xspd
player.y = player.y + yspd

num() takes in a boolean, and outputs a number (true being 1, false being 0)
The problem I have, is that I'm trying to stop the player if they hit a wall (The wall's sprite having flag 0), and I'm not sure what to do. Does anyone know what's going on?

"Gravity Wrangler"

Each world hurtles into the deep, feigning a wandering heart, accelerating their demise. What would they think if they realized that, through the eons, I was the only one standing between them and the frozen abyss...

Carlae is a itsy-bitsy snake in 𝟹̶𝟽̶𝟼̶ 358 characters, named after the cute tetracheilostoma carlae, but tetracheilostoma was kind of a mouthful.

DESCRIPTION

A.N.N.A. SYSTEMS OPERATIONAL.
PATIENT STATUS IS CRITICAL. MASSIVE INFECTION.
BEGIN PROCEDURE AS SOON AS POSSIBLE.
GODSPEED.

CONTROLS

Directional Keys control menu navigation and the A.N.N.A. CANNON. Press Z to fire and interact with menus. Enter to pause and reset / edit config.

NOTES

I was very lucky to be picked for the livestream of the game jam's submissions, and I had a great time working on what I would describe as 'Blood Peggle' - I hope you enjoy it as much as I liked making it. I do think we made it a bit too hard, but given that you can start on any level you like, I've opted to leave it as is.

CREDITS

This was a project for the A2B2 Game Jam, made by Remagamer and Eleven. You can follow me at https://twitter.com/Remagamer1 if you are so inclined.

Work In Progress:
A tool I made to help learn how fillp() code works as well as the 256 colour combinations.
In future I plan to add a hexadecimal readout as well as a means of changing the colour other than rewriting the colour table in _init(). Comments and better organisation of code is also on the to do list.

Typing help yield on the console or pressing CTRL+U on the yield() function reveals that the help text misspells yield() as yeild().

That's... about it, really.

Hey there! I'm here with a tool for you people wanting to show off that you, too, can have a website. My little tool here can make a website with your games on it in a jiffy, and has a tutorial for putting it on the web. Hope you like it!

Might style this if anyone cares

This is something I made for a request on reddit a while ago, and thought I'd share it here.

The timing objects are excellent for using in any game that needs precise timing actions. The timer bars are something I added later, and are not perfect.

> Hope this helps somebody! Timing can be a real headache. But this is very user friendly. There's a full section of notes in the cartridge!

This is a simple way to browse the internal pico-8 api, which I posted about on Twitter a while back.

I'm creating a small game where a player is on a grid of tiles. I want the player to move smoothly from one tile to the next, not appear instantly in the next tile. I tried to create a delay loop in the update function when the direction key was pressed, but the sprite still appears instantly 8 pixels to the left, right, etc.

The sprite is drawn, then when I hit, say, right, then the loop increments the x position, but it doesn't draw the sprite again until the loop is completed. How would I go about moving the sprite 1 pixel per frame for 8 pixels then stop?

I can sort of imagine what I need to do, but it's just a sort of jumble in my mind right now!

Add speech synthesis to your games with Speako8, a speech synthesis library for PICO-8 in under a thousand tokens! It's loosely based on a Klatt synthesizer and will remind some folks of Software Automatic Mouth (S.A.M.)

To add Speako8 to your games, copy and paste the library below:

Hi, I'm ghettobastler ! I make stuff using electronics and programming, and recently I became interested in PICO-8 because of its ability to control a Raspberry Pi's GPIO from within a game.
I read that this was done by using peek() and poke() on an address in the 0x5f80..0x5fff range, but unfortunately, I was not able to find the exact mapping online (i.e. which particular address corresponds to a given GPIO pin). So I made this tool to help me figure that out.

This is meant to be used on a Raspberry Pi or a similar board that has GPIO pins. It will not work in a browser or on a computer (I mean it will run... but there isn't any point in doing that)

It is pretty bare-bones, but it does the job. To use it, connect an LED and a resistor to one of the GPIO and run the cartridge (see this guide if you don't know how to do that).
