Documentation/Engine/Game data

All of SCS games are using partially prescribed folder structure. This means that some resources must have proper name and be placed into proper folder otherwise game may malfunction or even crash. That's why this topic is giving insight to game base folder structure, it's crucial resources and their place in folders.

In general topic is showing and describing structure of the folders and files as you get them by using Game Archive Extractor for two basic files with .scs extension found in game installation directory: "base.scs" and "def.scs".

Camera definitions

Camera definitions folder ("/def/camera") is using "camera_storage(.infix).sii" files as storage files defining cameras that can be used by player while in game (UI interface is not handled by cameras, as UI is drawn directly on screen 2D plane). Note that this defines only storage for available in game cameras, but which camera is used in the game depends on currently user selected view and current used player vehicle.

Beside storage files camera definitions folder also includes "cutscene.sii" file which defines camera and it's movement in different cut-scenes.

Root game folder 
├def
  ├camera
    ├...                        Folders for cut scenes camera definitions.
    ├ui                         Folder for storing camera movement definitions related to game desktop (main menu).
    ├units                      Folder for storing players camera included in "camera_storage" SII files.
    ├camera_storage.sii         Defining cameras storage that can be used in game by player. When creating your own cameras use infixed storage file name like: "camera_storage.mymod.sii".
    ├camera_storage.oculus.sii  Same as camera_storage.sii with purpose of defined cameras for Oculus Rift head set.
    └cutscene.sii               Defines cut scene data for each type.

Cargo definitions

This folder contains all cargoes definitions that player can transport in the game.

Unique cargo is defined by SII file and folder having one or more SII files defining trailers which can carry this cargo. So for each cargo you have one SII file inside "/def/cargo/" and one or multiple SII files inside folder "/def/cargo/<cargo_name>/". Example definition for cargo: "<cargo_name>" is shown in the tree below.

Root game folder 
├def
  ├cargo
    ├<cargo_name_1>             Folder defining trailers that can carry cargo defined in "<cargo_name>.sii" file.
      ├trailer.unit.name.sii    Defines trailer that can carry this cargo. SII file is named by trailer SiiUnit name.
      └...                      More definitions for different trailers carrying this cargo.
    ├<cargo_name_2>
      └...
    ├...                        The rest of cargo trailer definition folders.
    ├<cargo_name_1>.sii         Defining one cargo data.
    ├<cargo_name_2>.sii
    └...                        The rest of unique cargoes definition.

Climate definitions

Each climate is defined in it's own folder "/def/climate/<climate_name>/" and usually have profile SII files: one for nice weather "nice.sii" and second for bad weather "bad.sii". Climates definitions are used in Map Editor (Editor Settings -> Weather tab).

By default there should be at least two climates:

Root game folder 
├def
  ├climate
    ├reference    Reference climate.
      ├bad.sii    Climate definition for bad weather.
      └nice.sii   Climate definition for nice weather.
    └...          The rest of climates.

Company definitions

Companies are entry and exit places on map for player missions (e.g. trailer delivery). So when defining new company make sure to include it in company storage file "/def/company(.infix).sii" otherwise company won't appear in the Map Editor and later in game.

Company definition folder with included company "<company_name_1>" would look like:

Root game folder 
├def
  ├company
    ├<company_name_1>        Folder defining company data, named same as it's corresponding company data file.
      ├editor                Folder containing definitions for cities in which this company exists and which prefab will be used for it.
      ├in                    Folder containing SII files for cargoes this company accepts.
      └out                   Folder containing SII files for cargoes this company is shipping out.
    ├<company_name_2>
      └...
    ├...                     The rest of the folders defining other companies data.
    ├<company_name_1>.sii    File defining company: name, trailer look and sounds.
    ├<company_name_2>.sii
    └...                     The rest of companies definitions.

Country definitions

Defines available countries that can be used in the Map Editor and later in game. While defining new country make sure to include it in country storage file "/def/country(.infix).sii".

Each country has it's own folder defining all possible country specific data. Worth mentioning is modification of AI traffic appearing frequencies, which is done by adding SII files inside "/def/country/<country_name>/ai/" folder. Each SII file defines modified frequency for one AI vehicle, where it's name tells which car is it. Possible file names are AI vehicles unit name suffixes used inside AI vehicle definitions (AI vehicles definitions can be found in: "/def/vehicle/ai/").

Tree overview of country definitions:

Root game folder 
├def
  ├country
    ├<country_name_1>      Folder defining other country specific data: license plates, speed limits, AI cars frequency.
      ├ai                  Folder containing SII files for AI traffic vehicles, that should have modified frequency in that country.
      ├license_plates.sii  Defines license plate data for that country.
      └speed_limits.sii    Defines speed limits for AI traffic for that country.
    ├<country_name_2>        
      ├...
      └...
    ├...                   Folders for the rest of the countries data.
    ├<country_name_1>.sii  File defining country general data: id, name, country code, position, fuel price etc.
    ├<country_name_2>.sii
    └...                   The rest of the countries definition.

Ferry definitions

Defines names of the ferries and their connections. For proper working in game this ferries has to be used in Map Editor while adding Ferry points. All ferries also have to be included in ferry storage file "/def/ferry(.infix).sii".

Connections on the other hand are defined in "/def/ferry/connection/" folder. Each file in that folder defines one direction connection from one ferry to second ferry. How connection is directed is defined by SiiUnit name, so for example SiiUnit name: "conn.<ferry1>.<ferry2>" is presenting ferry connection from <ferry1> to <ferry2>.

Tree overview of ferry definitions:

Root game folder 
├def
  ├ferry
    ├connection   Folder with SII files defining connections between ferries. Each file defines one way direction between two ferries.
    └...          SII files defining ferries. Each file defines one unique ferry.

Sign definitions

Sign definitions are meant for new on-the-fly sign generation system which uses:

• Image atlases which are used to combine several related image into one and use atlas entries to address only part of the image.
• Frame templates which replaces sign background images for generated ones, where quality is not compromised with scaling.

Moreover sign definitions includes projects and template folder where game saves projects and end sign templates created within Map Editor.

Whole sign definitions tree structure:

Root game folder 
├def
  ├sign
    ├atlas            Defines image atlases for signs. SII files are created by hand.
    ├frame            Defines frames templates for signs. SII files are created by hand
    ├project          Defines sign projects which links associated data for example: creation of signs for one country. SII files are created by Map Editor.
    ├template         Defines signs template featuring all sign components, their positions and other properties. SII files are created by Map Editor.
    └templates.sii    Templates storage file including templates from "/def/sign/template/ folder. Also managed by Map Editor
