To allow user of this mod to create their own X4 mod that will allow of adding content based on existing models to the game.

This repo has a number of scipts to allow:

• extract_x4.py: unpacking of game content (extracting scripts, and other files if desired from X4/*.cat, into a SRC dir)
• compile_mod2.py: using yaml files modify specs of different ships, engines, weapons in existing game
• pack_mod.py: pack your MOD dir files into cat/dat and place them inside your X4/extensions dir, so you can test them right away in your game

When you extract the scripts with python3 extract_x4.py --extract the src dir should have all the script files

• all macros are indexed in ./src/base/index/macros.xml
• all components are indexed in ./src/base/index/components.xml
• ship macros are in ./src/base/assets/units/*/macros/ship_{arg|par|tel}_*_macro.xml
• shield macros are in ./src/base/assets/props/SurfaceElements/macros/shield_*_macro.xml
• weapon macros are in ./src/base/assets/props/WeaponSystems/*/macros/*_macros.xml

Note: base games are in /src/base, the dlc files are in /src/ego_dlc_*

see mods/rat2 for example

(work in progress)

• Step 1: Create config.py run ./setup.py or python3.7 setup.py (this should create a config.py with paths for present dir, game dir, src dir, mods dir)

• Step 2: extract X4 scripts run python3 extract_x4.py --extract (this should extract all the scripts/xml from the game cats+dats into src/ dir) (run python3 extract_x4.py --extract --all if you plan to want to work with the model files)

• Step 3: make modifications use: mods/rat2/content.xml mods/rat2/*.yaml as a templates to create your own mod

• Step 4: compile mod run python3 compile_mod2.py {your mod name} (this should read the yaml files and copy the appropriate xml source files, update them with values in csv, and place them in your mod dir.
  It should create the index, macros, components

• Step 6: pack your mod run python3 pack_mod.py {mod name} (this should take the files in your mods/{mod name}/, copy the files in root dir and pack the files in index, libraries, mod, and t dirs into your {game dir}/extensions/{mod name}/)

• Step 7: run game and verify it works In the game in Extensions you should see the name of your mod. If there are any issues look at your Debug Log (you can assign a key to it in Controls -> General -> Open Debug Log, you can open it without loading any saves, on game start) Note: if you add a ship or ware, it might not be in the Wharf/Shipyard you are docked at, it depends on the faction where it's available (this can be controlled in the libraries/wares.xml)

• auto path configuration via ./setup.py or python3.7 setup.py (ubuntu)
• extracting scripts and/or all files from game files via extract_x4.py
• packing mod files into cat/dat via pack_x4.py or pack_mod.py
• compiling mod from csv files via compile_mod2.py

Written and tested in the following environment

• OS:Written on Ubuntu 16.04
• PWD: ~/x4
• GAME DIR ~/.steam/.local/share/Steam/steamapps/common/X4 Foundations
• PYTHON3 VERSION: 3.5.2 (this can run most of the scripts)
• PYTHON3 VERSION: 3.6+ (required for the xmf2obj.py script)

• clone this repo
• if you have ubuntu 16+ you should already have python3.5 installed
• in a terminal in the repo dir run: ./setup.py which will try to auto detect your X4 game dir and create config.py
• (optional) if ./setup.py doesn't work, use config.py.sample to create your own config.py (adjust paths as necessary)
• after this you should be able to run python3 extract_x4.py --extract to exract the game scripts for most modding
• (optional) to extract all content, run python3 extract_x4.py --extract --all (this is necessary for xmf2obj.py)
• after the extraction, take a look at the mods/template dir or mods/rat to see examples of how to mod
• you can copy the template dir and create a mod based on it
• you can then run python3 compile_mod.py {your-mod-name} and in the mods/{your-mod-name} the script will create index, libraries, mod, t directories, and xml files in them (which you can further update as needed)
• you can then run python3 pack_mod.py {your-mod-name} and in your game X4/extensions/ {your-mod-name} dir should be created with the content.xml file and ext_01.cat and ext_01.dat files, which is your packed mod
• you should be able to run your game after this and use your new content
• if you plan to run the tests or xmf2obj.py, you will need to create a virtualenv with python3.6, source it, and pip install -r requirements.txt, then you can run ./run_tests.sh or './xmf2obj.py --all'
• for xmf2obj.py you can extract specific xmf files, or run xmf2obj.py --all to extract all ship models
