Looks like I finally made something with voxelspace terrain recent studies https://www.lexaloffle.com/bbs/?tid=35654

This Race The Sun partial demake is my first entry to #TweetTweetJam N°3, in Pico8 with a 560 characters limit !

The Goal

You must go as far as possible, with no sun :D

Ctrl + R to restart after crashing

Good luck and have fun !

Voxelspace experiments

Sun, 13 Oct 2019 19:50:29 UTC

At first, I saw a demo where a student implement a voxelspace algorithm with compute shaders. Voxelspace is a tech invented in the '90s by Kyle Freeman at Novalogic to render landscape. Games like Comanche, Deltaforce used it. It was based on heightmap and voxels, not polygon. I don't know much about shaders, but I know it is better at rendering polygons. So... I try to understand how all this work and here is the result: my voxelspace implementation on Pico 8

Here is an implementation of voxelspace rendering algorithm, with a little perlin noise map generation. Features :

Generate a 128x128 height map in memory,
Generate a color map base on height with some noise (I could also use height difference to better show cliffs and flat grounds, maybe latter),
colors fadding with distance
We can move, with player one controls, zoom map with X (or M), strafe with player 2 left and right (s,f)

I don't know where it will go, or if it will become a game, but here is my work :D Have fun tweaking or exploring !

PicoCyberbank is a cyberpunk remake of West Bank / Bank Panic by Damien Hostin, on twitter yourykiki (The Lurking Engine)

Goal :

you must help the bank collect the credchips by shooting the baddies and survive 9 days ! Beware some people are not as they seem to be at first !

Controls - keyboard or gamepad :

Use arrows to shoot left center or right
Use button 1 (x) or 2 (c) to change the doors you are looking

Behind the scene

This project was less complicated than Brutal Pico Race, I designed it to work with my kids... But actually, it was way too complicated for my little beginners, and they gave up after coding the open/close system for the doors :D It is also why there is a lot of functions in french. They came back for beta testing !

I keep some interesting parts for myself, such as the plasma doors, using the PX8 compression and a coroutine queue to load people graphics at runtime, a bunch of sprite picked up randomly to build the people, and little hidden surprises on the intro scene to reflect how far you went in the game !

Once again, great thanks to the pico 8 community !

Have fun !
