.pngdo 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/cookstandalone 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
- 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.txtfile. - 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-demandflag. - Linux/OSX users can optionally install wine and use the Windows tools instead (by using
--cook-wineflag). - Disable automatic cooking by using
--cook-jobs=0flag (not recommended). - Generate a project solution by dropping
engine/fwk.h, fwk.c and fwkfiles into it, orMAKE.bat sln. - Much faster builds by typing
MAKE.bat tcc(Win/Linux). Beware: compiler has no thread-locals support.
- Luajit: Luajit bindings are provided in the auto-generated fwk.lua file.
- Python: Python bindings are provided in the auto-generated fwk.py file.
- Nelua: Nelua bindings provided by Rabia Alhaffar.
