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 - The functions to be implemented by the Platform
• Platform - Implements the functions from Headers to work on a particular system
• ... - 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 - 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
