# unigi
|
|
unigi (Universal Graphics & Input) is a collection of headers, that implement a cross-platform API for drawing to the screen (framebuffer or window), and taking inputs (keyboard, mouse, joypad).

This repository contains documentation, links and example applications.

# Compatibility
|
|
* Highly compatible with compilers (C89, simple preprocessors)
|
|
* No `make` required, entirely configurable from your compiler, or header files
|
|
* Supports wide range of hardware (16-bit+, little/big endian)
|
|
* Standardized 16-bit color format (AAAARRRRGGGGBBBB, effectively 12-bit on most platforms)
|
|
* Screen coordinates are standardized
|
|
* Decent performance (Though some performance is sacrificed for standardization)
|

|
# Layers
|
|
A unigi app is built from different layers:
|
|
* [Headers](https://git.lumen.sh/Fierelier/unigi.headers) - The functions to be implemented by the Platform
|
|
* Platform - Implements the functions from Headers to work on a particular system (see below for a list)
|
|
* ... - Optionally, more layers
|
|
* App - Your code, uses other layers for input/output
|
|
|
|
# Platforms
|
|
Platforms act as the translation layer for different systems. The idea is to minimize the amount of work it takes to port graphical applications.
|
|
|
|
## Official platforms
|
|
* [SDL1](https://git.lumen.sh/Fierelier/unigi.platform.sdl1) - The highly compatible SDL 1.2, works on old Linux and Windows 95+
|
|
* SDL2 (soon) - SDL 2.x, works on somewhat recent Linux and Windows XP+
|
|
* DOS (soon) - DOS (Disk Operating System), compatible with FreeDOS and MS-DOS
|
|
* PSP (soon) - PlayStation Portable gaming console
|
|
* Null (soon) - A placeholder that does "nothing", good if you want to test basic compilation for an unsupported platform
