These are the .scar and .lua scripts found in CoH3's engine\archives\Data.sga and anvil\archives\Data.sga, useful for reference when scripting CoH3 mods. The engine directory contains the engine's scripts, and anvil the game's propper.
This was put together while developing coh3-bootstrap-mod, a mod template and Wiki to quickly learn and document Company of Heroes 3 scripting.
Of particular interest are the files described in the Win Condition template script:
engine\archive\data\scar\scarutil.scar: essential functions used almost everywhere.
anvil\archive\data\scar\game_modifiers.scar: if you're planning adding any modifiers to your mod. For example, if you want to change maximum population capacity or accuracy, sight range, health, etc.
engine\archive\data\scar\core.scar: This is required by all of the scripts found below:
anvil\archive\data\scar\ui\outcome_ui.scar: For default end of match flow.
anvil\archive\data\scar\audio\audio.scar: Audio support in general.
(These are already included in coh3-bootstrap-mod, BTW).
You can download the repo on the green <> Code button or with git clone https://github.com/Chematronix/coh3-internal-data-scripts. Add the directory to your VSCode project if you want to be able to look up a function definition by just pressing F12 or such.
Extracted after the Umber Patch, v1.3.0.18567. To extract a newer version, open the respective Data.sga file in the EssenceEditor.exe by doing File > Open... or dragging it to the tab bar. Select and right click the Data directory to Extract.
To remove non-.lua|.scar files and empty directories to greatly reduce the resulting size, run in a Linux/WSL shell on the containing directory:
find ./data -type f -not -regex '.*\.\(scar\|lua\)$' -print -delete
find ./data -type d -empty -print -delete
