Hello V4K

#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!");
    }
}

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 (Win) or sh MAKE.bat (Linux/OSX) to quick start.
• MAKE.bat all (Win) or sh MAKE.bat all (Linux/OSX) to build everything.
• MAKE.bat proj (Win) or sh MAKE.bat proj (Linux/OSX) to generate solutions/makefiles.
• MAKE.bat help (Win) or sh MAKE.bat help (Linux/OSX) for a bunch of options.
• MAKE.bat hello.c (Win) or sh MAKE.bat hello.c (Linux/OSX) to build a single executable.
• Alternatively,

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/ folder contains all the related binaries to perform any asset processing plus the cookbook to do so.
• Your game will cook all your assets as long as the tools/ folder is next to your executable. Alternatively, cook them all just by invoking supplied tools/cook standalone binary.
• 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/ folder.
• Update the gamepad controller database by upgrading the gamecontrollerdb.txt file.
• Depending on your IDE, you might need to browse to 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/ folder.
