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).

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 is achieved through platforms (See `src/platform`), which act as the translation layer for different targets. The idea is to minimize the amount of work it takes to port graphical applications.
|
This repository contains documentation, links and example applications.
|
||||||
|
|
||||||
The pixel format and screen coordinates are standardized, however, the HID inputs are not. It is best to make button layouts for each platform.

# Features

# Compatibility
|

* Highly compatible with compilers (C89, simple preprocessors)
|
* Highly compatible with compilers (C89, simple preprocessors)
|
||||||
* No `make` required, entirely configurable from your compiler, or a header file (`src/config/user.h`)

|
||||||
* Supports wide range of hardware (16-bit+, little/big endian)
|
* Supports wide range of hardware (16-bit+, little/big endian)
|

* Standardized 16-bit color format (RRRRGGGGBBBBAAAA, effectively 12-bit on most platforms)
|
* Standardized 16-bit color format (AAAARRRRGGGGBBBB, effectively 12-bit on most platforms)
|
||||||
* Implements API for floats, letting you pick between fixed point or actual float numbers
|
* Screen coordinates are standardized
|
||||||
* Decent performance (Though some performance is sacrificed to standardize the interface. On DOS, it targets 30 fps on i586-class CPUs)

# How to build
|
# Layers
|
||||||
## Preparation
|
A unigi app is built from different layers:
|
||||||
1. `git clone "https://git.lumen.sh/Fierelier/unigi"`
|
* [Headers](https://git.lumen.sh/Fierelier/unigi.headers) - The functions to be implemented by the Platform
|
||||||
2. `git submodule update --init --recursive` (optional, required for fixed point math)
|
* 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
|
||||||
|
|
||||||
## Platform: null
|
# Platforms
|
||||||
This platform has a very simple implementation, that is essentially a no-op for any possible target. It's meant for running a basic test before one makes a proper port.
|
Platforms act as the translation layer for different systems. The idea is to minimize the amount of work it takes to port graphical applications.
|
||||||
1. `cc src/tests/draw.c -Dunigi_flag_platform_null`
|
|
||||||
|
|
||||||
## Platform: dos
|
## Official platforms
|
||||||
This platform implements DOS (MS-DOS, FreeDOS, etc.), Tested with Open Watcom.
|
* [SDL1](https://git.lumen.sh/Fierelier/unigi.platform.sdl1) - The highly compatible SDL 1.2, works on old Linux and Windows 95+
|
||||||
1. `cc src/tests/draw.c -Dunigi_flag_platform_dos`
|
* 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
|
||||||
|
|
||||||
## Platform: sdl1
|
## Third party platforms
|
||||||
This platform implements the highly compatible SDL 1.2, which runs on all sorts of versions of Linux and Windows, as well as big endian CPUs.
|
...
|
||||||
1. `cc src/tests/draw.c -Dunigi_flag_platform_sdl1 -lSDL`
|
|
||||||
|
|
||||||
## Advanced configuration
|
|
||||||
### No stdint.h
|
|
||||||
If no stdint.h is available, one must define `unigi_flag_nostdint` and also one of `unigi_flag_alu_*bit` (`*` = 8, 16, 32, 64), depending on how wide the ALU of the target CPU is.
|
|
||||||
|
|
||||||
### Fixed point numbers
|
|
||||||
If fixed point is wished instead of float, one can define `unigi_flag_fixedpoint`. This uses the external fptc-lib headers.
