Hello FWK

#include "fwk.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 FWK from C!");
    }
}

#include "fwk.h" // Minimal HTML5 sample
void render(void *arg) {
    if( !input(KEY_ESC) ) puts("hello FWK from HTML5!");
}
int main() {
    window_create(75.0, 0); // 75% size, no extra flags
    window_loop(render, NULL); // game loop
}

local fwk = require("fwk") -- Minimal Lua sample
fwk.window_create(75.0,0) -- 75% size, no extra flags
while fwk.window_swap() and fwk.input(fwk.KEY_ESC) == 0 do -- game loop
    print("hello FWK from Lua!")
end

Quickstart

  • Double-click MAKE.bat (Win) or sh MAKE.bat (Linux/OSX) to compile everything.
  • MAKE.bat sln (Win) or sh MAKE.bat sln (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      && 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

  • Most asset types need to be cooked before being used in your application. Some other assets like .png do not.
  • Cooked assets will be written into .zipfiles close to your executable, and mounted before entering game loop.
  • Cooked .zipfiles and your executable are the only required assets when releasing your game.
  • Cook manually your assets by invoking supplied tools/cook standalone binary.
  • Cook automatically your assets by just playing your game: a runtime cook is already embedded into your binary.
    • In order to achieve this, ensure the tools/ folder is close to your executable.
    • This folder contains all the related binaries to perform any asset conversion plus the cookbook to do so.

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/fwk.h, fwk.c and fwk files into it, or MAKE.bat sln.
  • Much faster builds by typing MAKE.bat tcc (Win/Linux). Beware: compiler has no thread-locals support.
