Hey everyone! I recorded a quick screencast on how to get started with responding to player input and animating a sprite to match the input.

I don't know if this is a bug or feature, but it seems to me that nested loops do not work.
I attempted to use the following code, debugging the text showed that only one loop occurred:
local x=0 local y=0 while(x<16) do while(y<16) do val=mget(x,y) print(val) y+=1 end x+=1 end |
I don't know if this is intended or a limit of lua, but I was able to work around it with the following code:
local i=0 while(i<256) do local x=i%16 local y=(i-x)/16 val=mget(x,y) print(val) i+=1 end |

Working on making a simple RPG style game, so far I've just been working on getting the very basic movement and collision detection code working. Let me know if you have any questions. Thanks!

Here's the small shooter I made with the early version of pico-8.
- fire with Z
- launch all missiles with X
- missiles recover with time
- missile deal double damage on non-shielded targets

Hey.
I really like PICO-8 - it's really helpful to be able to learn a little tool, and stay inside that same tool until I finish a whole game.
However, one of my goals in playing with PICO-8 is to practice Lua.
Is there a way to turn off the PICO-8 specific syntax, so that I don't acquire "bad habits" of using += or whatever?
Thanks!

I'm not 100% sure this is working correctly but it was a good first try.

neato features:
persistent loading/saving (not sure yet if this works in the web player?)
day/night cycle
shitty music

This is just me trying to learn how to use the map data. That tempting "door" at the top doesn't work yet.

The Argus is watching all, always,. .
(small graphic/sound test)
loving the hard limits of this system,.
except the color limit, can we currently peek/poke to dynamically alter the colors in the 16 ?
I like the limit of 16 palette,. however would rather be able to change these sometimes., all greens or blues,. cycle one, etc.
very cool system otherwise.

You are Flynn Flier, Ace Aerospacer, Space-Dart Superhero! After escaping Tranus's Test, you fly to planet Zondak, a land of energy-ball beings! You've been tasked with circumnavigating Zondak--with every ball of plasma on the planet trying to kill you! Weave through the world of the Zondaks, zapping everything in your way! Will you make it through the 13 zones of Zondak?
SPACE-DART PILOT'S MANUAL Use the ARROW KEYS to maneuver your craft LEFT, RIGHT, FORWARD, and BACKWARD. Note that you will pilot this ship in THREE DIMENSIONS! Press the Z key to ASCEND. Release the Z key to DESCEND. Your ship will automatically hover above the ground, so don't worry about crashing! Apply pressure on the X key to fire an ENERGY BLAST. Your ship can only manage the energy for one ENERGY BLAST per second, but each one is powerful enough to disrupt one Zondak Plasma Sphere. You will score 10 points for each Zondak Plasma Sphere you destroy, and clearing a zone scores you 100 points times that zone's number (clearing zone 1 gives you 100 points, zone 2 gives you 200, etc). You have 3 LIVES to reach Zone 13. Once you have made it past the final zone, you will see the GAME OVER screen, with your final score flashing on screen. Post a screenshot of this screen, with the zone and score clearly visible, and see how you stack up against other pilots! |

Over Ludum Dare #32, sugarbyte and I made Extinction Explosion!!one!
While reviewing games, I discovered PICO-8.
This is (the beginning of) a very crude demake, of the already simple jam game.

A simple little 2.5d test. Arrow keys move left/right and "forward/back", Z key jumps.
I created this effect by drawing the sprite to the screen at X, Y+Z*"angle" where "angle" is a value between 0 and 1.
For this demo, it's set at 0.5.

sin(0.25) that as far as I understand resolve to sin(0.25 PI 2) returns -1 counter intuitive to traditional math +1
Is this intentional?

Hi everyone! Here goes my first submitted thing : a recreation of the good old rotoscaling effect, quite known in the demoscene... scene... in way less than 1kb of code. I made it fit to a round 1kb by comments in the source code to explain some tricks about the calculation.
Rotoscaling is based on two things : rotation (good old cossin sin-cos) and scaling. I precalculate scaled sine and cosine tables according to the current angle in the update loop to gain some overall speed.
I programmed it on the alpha 0.0.5. I don't know if anything changed around to the speed/cpu usage but this should run quite quickly (don't expect 30 FPS neither, I couldn't make the pixel blit faster) on the 0.1 alpha.
I really liked playing with PICO and I'm not done at all with it! :D

You are Flynn Flier--Star Speeder! Known throughout the galaxy as one of the fastest pilots in the universe, you've always loved dodging danger and dashing through deadly dares.
One day, as you zoomed through the Altair constellation, you happened across a wormhole. Being the brave adventurer you are, you stepped on the gas and slipped through the tear in space-time...
You find yourself in a strange labyrinth, with your lazers disabled and a booming voice in your ear:
"I AM TRANUS, MIGHTY RULER OF THE MAZE YOU SEE BEFORE YOU. I ISSUE YOU A CHALLENGE, FLYNN FLIER--PASS THROUGH ALL THREE ZONES OF THE LABYRINTH, AND I SHALL SET YOU FREE!"
Your space-dart's engines roar behind you. The only way out is to get through the barriers before you. Will you reach the final Zone?
SPACE-DART PILOT'S MANUAL Use the ARROW KEYS to maneuver your craft. The Z KEY will perform a BARREL BOOST ROLL. This will make your SPACE DART speed up. However, you won't be able to move while performing the BARREL BOOST ROLL! You will score POINTS for flying through the holes in the WALLS at high speed, and for staying near the right edge of the screen. You score more points for moving quickly--but beware, your SPACE DART is not built for collisions, and running into a wall is sure to end in disaster! Your ship will AUTO-ROLL every four walls. Be prepared! Flying is harder when you're moving too fast to see! You will start in ZONE 0. After 5000 POINTS, you will reach ZONE 1. After 10000 POINTS, you will reach ZONE 2. Post a screenshot of your ship flying through ZONE 2, with your score clearly visible, and show off to your friends that you've passed Tranus's test! |

how much code do you usually write in there?
at around 400 lines it's getting hard to manage for me.
