The wiki has detailed information on everything (https://github.com/alec101/OSInteraction/wiki)
When you write a program using OSI, the same code will run under Windows, Linux and MacOS, without changing any line of code.
One of the main features of OSI is to create any number of OpenGL windows, on any number of monitors. If the system has multiple graphics cards, all of them can be used in rendering. Each of these windows can be a full screen window, normal window or a window that spans on all system monitors (this last type of window uses only 1 graphics card to render with OpenGL - to use all graphics cards, 1 full screen window per monitor must be created). Today's games and applications do not use more than 1 graphics card usually and for sure will not work on all 3 big operating systems. Imagine a strategy game: on one monitor you have the map, on the other, building queues, factories, maybe a radar etc... don't know why so very few games use this kind of feature.
Mouse/Keyboard/Joystick/ Gamepad (every kind) / GameWheel (all main HID's) support, for all OS-es, with almost all driver types (XInput, DirectInput, linux joystick.h method, etc)
The Keyboard class was designed to be able to build Mortal-Kombat style games, if you wish - it has a history of the keys that were pressed and their time when they were pressed and depressed. It has support for text input and editing in unicode and many more things, about everything you need from a keyboard.
osiDisplay class scans every monitor connected to the system, and stores it's capabilities - resolutions frequencies, etc. This data is easy to access, and is sorted and stored in the same manner under Windows/Linux/Mac.
High performance timers for all OS-es (same function names, same variable outputs).
OpenGL functions that have different usage mode/names under each OS, are nicely combined under 1 function. (ex: call glMakeCurrent(....), which knows to call wglMakeCurrent under WIN, glxMakeCurrent under LINUX, blaBlaBla under MAC)
tired of setting the locale to utf8/blabla, that just doesn't work on all systems? or just doesn't work, period? use supplied str8 class that uses only UTF-8 strings, or the UTF-32 class str32. Str namespace have functions that apply to UTF-8 / UTF-32 strings
Tons of other nice stuff.
main() { osi.createGLWindow(&osi.win[0], // creates an OpenGL window - first parameter is what window object to use (there are 64 pre-alocated) &osi.display.monitor[0], // specify on what monitor to create the window "Win 0", // window name 500, 500, // window size OR if fullscreen, what resolution to change the monitor to 1); // window mode: 1-normal window; 2-fullscreen; 3-fullscreen window(ignores size); 4-fullscreen window on all monitors(also ignores size)
in.init(); // initializes mouse / keyboard / rest of HIDs
while(1) { // a basic program loop
osi.checkMSG(); // checks system messages
in.update(); // updates HIDs (mouse / keyboard / activated joysticks
if(in.k.key[in.Kv.esc] || osi.flags.exit) // if escape key is pressed or the system signaled the program to close, break from the loop
break;} }
Needs tons of bug squishing - all this was done only by me (alec.paunescu@gmail.com), so i expect tons of bugs that i missed
Check out OSinteraction.h for further compiling instructions & other info
Needed libraries to compile:
LINUX libraries: [X11] [GL] [GLU] [Xrandr] [Xinerama]
WIN libraries: [opengl32] [glu32] [d3d9] [dinput8] [dxguid] [xinput]
MAC frameworks: [-framework Opengl] [-framework cocoa] [-framework IOKit] [-framework CoreFoundation]
Detail library explanation:
LINUX libs: [X11] - libX base - don't leave home without it [GL] [GLU] - OpenGL libraries [Xrandr] - used for monitor / GPU info / monitor resoulution changes [Xinerama] - used for monitor position info only
WIN libs: [opengl32] [glu32] - OpenGL libraries
if any dinput, xinput or direct3d are used, some directx sdk files (libs+includes) are provided, but directx sdk can be downloaded and used instead
[d3d9]: [#define USING_DIRECT3D] must be set in osinteraction.h - used ONLY for GPU detection (hopefully oGL will have an extension for this, in the future)
[dinput8] [dxguid]: [#define USING_DIRECTINPUT] must be set in osinteration.h - used for direct input HIDs - joysticks gamepads etc
[xinput]: [#define USING_XINPUT] must be set in osinteraction.h - used for xinput HIDs - probly only gamepads
the next libs should be auto-included, but here is the list in case something is missing:
kernel32.lib;user32.lib;gdi32.lib;winspool.lib;comdlg32.lib;advapi32.lib;shell32.lib;ole32.lib;oleaut32.lib;uuid.lib;odbc32.lib;odbccp32.lib;%(AdditionalDependencies)MAC frameworks: [-framework Opengl]: opengl library, basically [-framework cocoa]: macOSX api [-framework IOKit]: some monitor functions use this lib [-framework CoreFoundation]: used for simple error message boxes only
How to get the neccesary libs under Linux / Ubuntu:
sudo apt-get install mesa-common-dev GL/gl.h GL/glx.h
sudo apt-get install libglu1-mesa-dev GL/glu.h
or the freeglu one
sudo apt-get install libx11-dev for X11/Xlib.h - probably this is already installed
sudo apt-get install libxrandr-dev used for resolution changes
sudo apt-get install libc6-dev-i386 the 32-bit C libraries (only 64bit libs are in linux64)
sudo apt-get install xxxxxxxxxxxx the 64-bit C libraries (only 32bit libs are in linux32)
sudo apt-get install libxinerama-dev Xinerama header files, used to identify monitors
sudo apt-get install gcc-4.8-multilib g++-4.8-multilib - or whatever your gcc version is, if you get [fatal error: 'bits/c++config.h' file not found]
http://unlicense.org/ - so you can do whatever you want to do with this code - copy, change, wipe the floor, etc without any kind of pressure. Hope it helps!
