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!")

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.
- In order to achieve this, ensure the
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, orMAKE.bat sln
. - Much faster builds by typing
MAKE.bat tcc
(Win/Linux). Beware: compiler has no thread-locals support.
Bindings
