Compiling

Windows:

get qtCreator for mingw get zlib source and complied there http://www.winimage.com/zLibDll/ Copy zlib.h and zlib_bor.lib in C:\libs\ Open .pro file compile

Linux:

sudo apt install qtcreator zlib
qmake
make

Automatic cross compilation from linux

Create docker image from: https://github.com/jmimu/crossqt

Then, from distrib directory:

docker run --rm --device /dev/fuse --privileged -v $(pwd)/..:/pakedit crossqt1804 /pakedit/distrib/compile_all.sh

Getting Started

Copy io_alone/ to bender/2.9x/scripts/addons/

Make a copy of your original PAK files.

Run AITD_PakEdit. Open a database corresponding to the game (AITD1_PAK_DB.json for AITD1). Open a PAK.

You see every file in the PAK, with there description and type from the database. You can modify them and overwrite database (and send it to me for next release!). When selecting a file, you can export it depending of its type. For now you can export raw files (just decompressed), pictures, texts, palettes+pictures, sound samples and floors (not finalized). For now only pictures, texts, sound samples and raw files can be re-imported. You can then modify the exported files, and re-import them. Overwrite the PAK file (a .PAK.BAK file will be created to save previous version). Run the game with the new PAK.

To be able to re-import compressed files (mandatory for bodies), you have to install Dosbox emulator and set dosbox executable path (if it is not in system's PATH) with Settings>Set Dosbox Path menu. You also have to get PKZip 1.1 executable, and give its path with Settings>Set PKZip Path menu.

Floors are exported in Collada format. You can open it with meshlab or blender. To have a correct superposition with the background images, you must stretch them into 320*240 or set blender's output Y aspect to 1.2. Objects names are : type_rX_tY_pZ, where X is room number, Y type and Z parameter. You have to change those names in order to change objects metadata.
