- 1 Introduction
- 2 TIC-80
TIC-80 is a fantasy computer for making, playing and sharing tiny games and demos.
There are built-in tools for development: code, sprites, maps, sound editors and the command line, which is enough to create a mini retro game. At the exit you will get a cartridge file, which can be stored and played on the website.
Also, the game can be packed into a player that works on all popular platforms and distribute as you wish. To make a retro styled game the whole process of creation takes place under some technical limitations: 240x136 pixels display, 16 color palette, 256 8x8 color sprites, 4 channel sound and etc.
As the TIC-80 fantasy computer is an all-in-one creation and execution platform, setting up TIC-80 is very easy:
Just go to the https://github.com/nesbox/TIC-80/releases page
and download the package for your platform of choice (Windows, OSX, Linux and even Raspberry Pi).
Or if you are just curious you can just start doodling online at http://tic80.com/
The TIC-80 has a 240x136 pixel display with 16colors which can be accessed via a wide range of graphics functions or by writing directly to VRAM at memory address 0x0000 using the poke4 instruction.
There are a couple of built-in drawing functions you can use:
cls(color=0) pix(x,y[color]) [-> color] circ(x,y,r,color) -- filled circle circb(x,y,r,color) -- border circle rect(x,y,w,h,color) -- filled rect rectb(x,y,w,h,color) -- border rect line(x0,y0,x1,y1,color) tri(x1,y1,x2,y2,x3,y3,color) textri(x1,y1,x2,y2,x3,y3,u1,v1,u2,v2,u3,v3,
scale=1,smallfont=false) -> width
Getting something on screen
Here is a bit of code to get you started:
function TIC() t=time()/99 for y=0,136 do for x=0,240 do pix(x,y,(x>>3~y>>3)+t) end;end;end
Which will display an animated XOR pattern.
Unfortunately for us sizecoders, the pre v0.8 TIC-80 came with a different palette than the now standard (and much more friendly) sweety16 palette. And because of backwards compatibility, this old palette is also the default palette that is being used when now palette chunk is defined in the TIC cart.
The TIC-80 has soundregisters and 32 byte waveforms to access
Make some noise
To be added soon.
Compression And Release
Sizecoding on the Atari ST is not very huge yet, so resources are sparse. Here are some bytetros with source code:
Online version: Metadata and Thumbnail image
When uploading the intro to the TIC80 website for an playable online version, you will need to build a new TIC file with some added some meta-data and Thumbnail image (You can take this snapshot using the F7 key) and use this as you online version.
The Meta data is added at the top of your intro as follows
-- title: My intro -- author: scener -- desc: my first sizecoded TIC-80 intro -- script: lua (or moon/wren/js/fennel)
Sizecoding on the TIC-80 is still in its infancy, but luckily there is already plenty of information to get you started!
