Changes

All of SCS games are using partially prescribed folder structure. This means {{Tip|Be aware 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 page is giving insight obsolete, due to big changes in game base folder structure, it's crucial resources and their place in folderswith each update!

 All of SCS games are using partially prescribed folder structure. This means that some resources must have the proper name and be placed into the proper folder otherwise game may malfunction or even crash. That's why this topic is giving insight to game base folder structure, its crucial resources and their place in folders. In general , this topic is showing and describing the structure of the folders and files as you get them by using the [[Documentation/Tools/Game Archive Extractor|Game Archive Extractor]] for two basic files with .scs extension found in game installation directory: "'''base.scs'''" and "'''def.scs'''".

├{{FileSystemTreeEntry|icon=FST-IconFolder|type=|name=map}} ''Storage for maps and it's its additional data.''

├{{FileSystemTreeEntry|icon=FST-IconFolder|type=|name=city}} ''Defines cities for game. Each city is defined in it's its own SII file.''

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

Each climate is defined in it's its 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).

├{{FileSystemTreeEntry|icon=FST-IconFolder|type=|name=<company_name_1>}} ''Folder defining company data, named same as it's its corresponding company data file.''

Each country has it's its 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 its name tells which car it 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/'''").

Vehicle definitions are responsible for configuration of any type of vehicles and it's its parts in SCS games that are not map assets. Biggest part of this configurations belongs to configuration of possible player vehicles and it's its parts.

├{{FileSystemTreeEntry|icon=FST-IconFolder|type=|name=truck_dealer}} ''See: [[#Truck dealer definitions|Truck dealer definitions]].''

Trailer definitions defines trailers for usage with players truck or for usage by AI traffic. For defining a trailer, one SII file and folder with "'''chassis.sii'''" and/or additional cargo definitions has to be created. All of the trailers definition files also have to be included in one of the storage files to be used in game. In case trailer should be used by player it has to be included in one of the "'''trailer_storage(.infix).sii'''" files and if trailer should be used by AI trucks it has to be included in one of "'''trailer_storage_semi_trailertraffic_storage_semi_trailer(.infix).sii'''" files or custom type of AI trailers storage file.

{{Note|Difference between AI trailer trailers and players trailer is in player trailers are handled somewhat differently. Player trailers use the type of SiiUnit in trailer definition file, where players trailer SiiUnit name is "'''trailer'''" and AI SiiUnit class with a naming convention of <code>trailer SiiUnit .<name is ></code>, while AI trailers use the "'''traffic.trailertraffic_trailer'''"SiiUnit class and a naming convention of <code>traffic.trailer.<name></code>.}}
