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! |
Spent my evening making a simple thing that pokes colors from a few preset palettes to the display memory. Added a modulus feature that makes the scrambling form into a few cool patterns.
Up/Down controls the modulus, Left/Right controls the magnitude (700 max w/ modulus, 1500 without) and Button_A changes the palette.
After looking in the forums a little, I've found out how to get Pico-8--but it's not really clear, so I figured I'd put it down in a forum post for anyone looking through Google.
TO ACQUIRE A PICO-8 FANTASY GAMING CONSOLE:
Step 1: Go buy Voxatron.
Step 2: Give it a minute or so. You'll need to let the payments process and such.
Step 3: You will be able to request a download link for the PICO-8 FANTASY GAMING CONSOLE from your MY GAMES tab.
Step 4: Download and start making games!
Original post, for posterity:
Two player game. Players try to draw a line into the other by holding the button down to draw. Pick up ink bottle power-ups to increase your draw speed, ink reserve, and refresh speed.

my submission for Ludum Dare 32. left and right arrow keys only
curse the earth with the power of prayer
if you could, please play and rate the game.
thanks zep for the amazing tool!
Howdy folks, this is my submission for LD48 #32! Definitely rough around the edges, but for my first work with Pico8 I am delighted.
There are some moving background and stuff that might cause motion sickness, so I included a no-blinky version that should have most of that gone.
Before playing, read the rules so you know how it works:
- defeat your opponent by making BINGO
- you have a 3x3 bingo card and a hand of 3 numbers below it
- you and the CPU take turns playing numbers until someone gets a bingo
- OR until the DEAD PILE fills up
- numbers played that aren't on either player's board go in the DEAD PILE
- if the DEAD PILE fills up (5 numbers), whoever played the last number loses 5 life
- if someone gets BINGO, the other player takes 5 damage per BINGO plus the size of the DEAD PILE
- you each start with 15hp
There are four stages and it should go quick; hope you enjoy!
