|Version: | 2024.9 | |:--------------|:------------| |Revision: | 133 | |Branch: | 1 | # [V·4·K 2024.9 ](https://v4k.dev) ## a b o u t - Envision, Prototype, Perfect. - visit the code repo at [v4k-mirror](https://github.com/zpl-zak/v4k-mirror) now! - you can try out the [live demo](https://demo.v4k.dev), too! - and for anything else, reach us at [v4.games](https://v4.games/).
Code style ```C linenumbers /// ## Markdown comments when documenting (3 slashes) // C++ comments allowed /*C comments too*/ // Order matters: includes -> defines -> enums -> structs -> functions #define puts(x) my_printf("%s", x) // lowercase defines allowed for syntax sugars #define VERSION "1.0.0" // uppercase defines otherwise enum { ZERO = 0 }; // uppercase enums. also, one-line brackets allowed void assert_positive( int my_int ) { // lowercase snake_case everywhere int *x = &my_int; // no spacing between pointers and variables if( *x < ZERO ) { // no outer padding space after if,do,while,for,switch puts( "Negative" ); // inner padding space around operators and parenthesis } // 4-spaces indents, 1TBS brackets } // when in doubt, dont worry & mimic style from codebase ```

Hello V4K ```C #include "v4k.h" // Minimal C sample int main() { window_create(75.0, 0); // 75% size, no extra flags while( window_swap() && !input(KEY_ESC) ) { // game loop puts("hello V4K from C!"); } } ``` ```lua local v4k = require("v4k") -- Minimal Lua sample v4k.window_create(75.0,0) -- 75% size, no extra flags while v4k.window_swap() and v4k.input(v4k.KEY_ESC) == 0 do -- game loop print("hello V4K from Lua!") end ```
Quickstart - Double-click `MAKE.bat` to quick start. - `MAKE.bat all` to build everything. - `MAKE.bat proj` to generate solutions/makefiles. - `MAKE.bat help` for a bunch of options. - `MAKE.bat hello.c` to build a single executable. - Alternatively, ```bat echo win/vc && cl hello.c echo win/clang-cl && clang-cl hello.c echo win/tcc && tools\tcc hello.c -m64 echo win/mingw && gcc hello.c -lws2_32 -lwinmm -ldbghelp -lole32 -luser32 -lgdi32 -lcomdlg32 echo win/clang && clang hello.c -lws2_32 -lwinmm -ldbghelp -lole32 -luser32 -lgdi32 -lcomdlg32 echo linux && cc hello.c -lm -ldl -lpthread -lX11 echo linux/tcc && tcc hello.c -lm -ldl -lpthread -lX11 -D__STDC_NO_VLA__ echo osx && cc -ObjC hello.c -framework cocoa -framework iokit -framework audiotoolbox ```
Cook - Assets need to be cooked before being consumed in your application. The [tools/](tools/) folder contains all the related binaries to perform any asset processing plus the [cookbook](tools/cook.ini) to do so. - Your game will cook all your assets as long as the [`tools/`](tools/) folder is next to your executable. Alternatively, cook them all just by invoking supplied [`tools/cook` standalone binary](tools/). - In both cases, assets will be cooked and packed into .zipfiles next to your executable, then mounted before entering game loop. These .zipfiles plus your executable are the only required files when releasing your game.
Extra tips - Any ico/png file named after the executable name will be automatically used as app icon. - Similar to the ico/png case above, the cooked .zipfiles can be named after the main executable as well. - Dropped files into game window will be imported & saved into [`import/`](engine/art/import/) folder. - Update the gamepad controller database by upgrading the [`gamecontrollerdb.txt`](engine/art/input/) file. - Depending on your IDE, you might need to browse to [`engine/split/`](engine/split/) sources when debugging FWK. - Cook assets on demand, as opposed to cook all existing assets on depot, by using `--cook-on-demand` flag. - Linux/OSX users can optionally install wine and use the Windows tools instead (by using `--cook-wine` flag). - Disable automatic cooking by using `--cook-jobs=0` flag (not recommended). - Generate a project solution by dropping `engine/v4k.h, v4k.c and v4k` files into it. - Auto-generated Luajit and Python bindings can be found in the [`engine/bind/`](engine/bind/) folder.
