Table of Contents

​
Core Technical Changes

​
JavaScript-Based Modding

  • Civilization VII uses JavaScript instead of Lua for modding (confirmed by multiple modders)
  • This is a significant change from previous Civilization games that used Lua
  • Waiting for official modding tools to provide JavaScript API documentation
  • Modders familiar with Lua will need to adapt their approaches and learn JavaScript
  • The map scripts in base-standard/maps provide examples of JavaScript implementation
  • No gameplay DLL is visible, with core functionality packed in executable files
  • The JavaScript API extent is currently unknown, but expected to be robust based on prior games

​
File Structure

​
Core Files

  • Uses .dep and .modinfo files for DLC and mods
  • DLC structure can serve as examples for mod creation

​
Age System Organization

The game uses a modular age system with separate files:
  • core.modinfo - Core game systems
  • base-standard.modinfo - Base game content
  • age-antiquity.modinfo - Antiquity Age specific content
  • age-exploration.modinfo - Exploration Age content
  • age-modern.modinfo - Modern Age content

​
Global Parameters

  • No longer contained in a single XML file
  • Split across multiple files based on relevance
  • Some Civilization VI artifacts remain in parameters
  • Parameters are era-specific

​
Modding Capabilities

​
Map Generation

  • Map scripts are editable and can be modified for custom maps
  • Located in: steamapps\common\Sid Meier's Civilization VII\Base\modules\base-standard\maps
  • Current maximum map width: 128 tiles (confirmed by Gedemon on CivFanatics)
  • Map generation parameters can be modified
  • Each map type has its own script file in the maps directory
  • Scripts appear to be written in JavaScript, consistent with other modding changes
  • Custom map types can potentially be created by duplicating and modifying existing scripts

​
Asset Management

  • Assets are loaded/unloaded between eras during age transitions
  • Possibly implemented due to Civilization VI asset limit bug (suggested by Gedemon)
  • May affect how mods handle era-specific content
  • Buildings from previous ages remain on map after transition despite asset unloading
  • Global parameters are era-specific and split across multiple files (discovered by thecrazyscot)
  • Each age has its own modinfo file that defines its content and assets
  • Modders should consider creating age-specific mods that respect this architecture

​
Known Limitations

​
Technical Restrictions

  • No visible gameplay DLL
  • All core functionality packed in exe files
  • Denuvo protection may limit certain modding capabilities
  • Art definitions (artdef) currently packed
  • Unit model modding may require SDK release

​
Tips & Tricks

​
Working with Ages

  • Consider asset loading/unloading when creating era-specific content
  • Buildings from previous ages remain on map after transition
  • Each age module can be modified independently

​
Map Modding

  • Scripts for each map type are editable
  • Located in base-standard/maps directory
  • Consider 128-tile width limitation
