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!

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).

Let me clear things up:
I don't know trigonometry.
I made this from my incredibly basic understanding of it.
Do not expect this to be great.
But I mean, it kinda gets the job done?
anyway, here it is.
PHOTOSENSITIVITY WARNING: If the character reaches the mouse, it moves left and right fast.
(Please explain to me how to do trig for this in the comments)

This is just a simple first game I created in order to get used to the engine and get back into the swing of LUA.
Any feedback is of course welcome, but I don't think I'll touch it much after this!

PICO-Patch is an 2OP instrument and music sequence creator for PICO-8, developed by MegaSparky as a spiritual successor to his independently released tool 4OP-8. It allows users to create instruments by mixing two sine wave operators in different ways and create melodies with them.
Controls:
All actions are controlled with the mouse cursor/touchscreen, except for playing notes. To trigger a note outside of play mode, press (o) - z on the keyboard - and use the d-pad/arrow keys to change the note that you play; left and right changes it to the previous and following one respectively, while up and down switch octaves.
Creating instruments:
PICO-Patch features four types of sound synthesis: phase modulation (PM), amplitude modulation (AM), ring modulation and additive. The "ADSR" parameters allow you to modify each operator's attack, decay, sustain and release respectively. The "V" meter controls the operator's global volume, and the "M" parameter defines the multiplication of its frequency.

press x to randomize colors ^-^
thanks to pixienop's webpage on tweetcarts for the sin usage tips used on this program!

i'm not managing to get the music player to play music, and all the controls also seem to be doing nothing. see this post for an example:
https://www.lexaloffle.com/bbs/?tid=43733
i also checked with more recent posts that use the music player. i tried both latest firefox and chromium on linux mint 20.3. i don't have the tab muted, and other applications as well as other sites and the cart player still play sound

Made this as a birthday gift for my wife.
I hope she enjoys playing it on her new retro device.
Instructions:
The goal is to save all the bunnies from the wolf/fox
- collecting all coins will automatically purchase & place the burrow

Hello!
I have just started working on a little metroidvania-style platformer. I started by following the platformer tutorial on [youtube]Youtube[https://www.youtube.com/watch?v=q6c6DvGK4lg&list=PLyhkEEoUjSQtUiSOu-N4BIrHBFtLNjkyE] and looking at some carts here.
I want to have different rooms connected by doors, which I have all drawn in the map editor. But apparently I don't understand how the map() function works.
I have one rooms that stretches from the map cells x000/y000 to x063/y015 and another smaller one below that from x000/y016 to x026/y022. I have a simple camera function like this:
function update_cam(m_start, m_end)
cam_x=plr.x-64+(plr.w/2)
cam_y=plr.y-64+(plr.w/2)
if cam_x<m_start then
cam_x=m_start
end
if cam_x>m_end-128 then
cam_x=m_end-128
end
camera(cam_x,cam_y)
end |
I have collision checks done like this:
function collide_map(obj,aim,flag) -- obj = table needs x,y,w,h [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=116420#p) |

An HACK*MATCH demake
HACK*MATCH is a series of puzzle games by Zachtronics in the vein of the Magical Drop series of arcade games.
Its first appearance was as a mini-game in EXAPUNKS, then it came back as a standalone game on the NES and its last appearance was in Last Call BBS as a emulated arcade game.
The arcade version from Last Call BBS was quite addictive and I wanted to make a demake to play it on-the-go.

Hi, I think the tittle is self explanatory. I always had to fight against that lua lack. I came from c, so I am very accustomed to use the inline conditions. And it can be very useful for shrink code, like with tweetcarts. I know, there are some approaches in lua to solve this, but an official and explicit way would be very good.

Completed this game as part of the LazyDevs Basic Shmup Showcase Game Jam. I was going for a bit of a Star Wars-y vibe, though I was also influenced by the shooter I grew up with as a kid, Star Solider on the NES.
The soundtrack was inspired by a chord progression used in a lot of Japanese pop and Anime theme songs, with just a pinch of Duck Tales Moon Theme in the mix.
First edit: commented out the code that clears the high score every playthrough. Oops.
Second edit: V2 with powerups that bounce off the sides/top.
Third edit: V3 with levels that persist until all powerups are collected or exit the screen. Adds difficulty settings and logic that ties percentage chance of getting shields vs laser upgrade to the current % shields remaining.

I just recently watched Stargate again and I like the song from the last episode.
Feel the infinite unknown space. Let's hope for a new Stargate series.

Hello.
Now that we can access strings a little easier I am coming across a problem I did not have in GFA or QBASIC.
For instance is there a way to have a function change an argument in return ?
function addadd(static a) a=a.."+" end cls() a="hello" addadd(a) print(a) |
Result would be: hello+

Hey All!
PICO-8 0.2.5 is now up on lexaloffle, Humble, itch.io, and for PocketCHIP and web (Education Edition).
Edit: 0.2.5b is now up for Linux users who had trouble connecting to the BBS: https://www.lexaloffle.com/bbs/?pid=116441#p
Built-in Help
PICO-8 0.2.5 has built-in documentation on API functions and other topics. Type "HELP" at the prompt to see a list of topics in blue, and then e.g. "HELP GFX" to get more information about that thing.
While in the code editor, you can also press CTRL-U to get help on whatever is under the cursor, including operators and Lua keywords.
> HELP FILLP |
String Indexing
Single characters can now be grabbed from strings using a familiar str[i] style syntax that means something similar to sub(str, i, i). The index is rounded down to the closest integer, and can be negative to index from the end of the string.

Where it says...
"Stretch an rectangle of the sprite sheet (sx, sy, sw, sh) to a destination rectangle on the screen (sx, sy, dw, dh)."
...it should say "(dx, dy, dw, dh)" instead.
Although if you read the paragraph fast enough your brain probably autocorrects it, heh.

Feature Overview
TTABLE() returns the table if the argument is a table.
- Returns FALSE if not a table.
- Use when table or string determination is required.
- e.g., when using a string for initialization and replacing it with a table
- Simultaneously check the type and reference the contents inline, as in
type(tbl)=='table' and tbl.
- This function consumes 10 Token.
tbl = '1 5 10' -- Default value.
tbl = ttable(tbl) or split(tbl, ' ') -- tbl = {1, 5, 10}
----
----
-- Thereafter, the tbl is not initialized even if there are changes to the elements of the tbl.
tbl = ttable(tbl) or split(tbl, ' ')
|
This function is included in the KNUTIL library.
