Documentation/Engine/Game data/Player trucks definitions
Player trucks are defined using two complementary systems of unit definitions. Data definitions describe the characteristics of the truck and its many accessories. Think of these as a set of building blocks from which the truck can be built; They don't assemble themselves! Vehicle definitions configure the data definitions into a vehicle that may be driven or purchased. Think of them as the instructions for the game to assemble the building blocks (data definitions) into a vehicle when it is first loaded.
Each truck is configured in its own folder (e.g. "<brand.truck>" in tree view below) containing:
- SII file: data.sii - defining: truck info, cameras, fallback rules for parts of the truck and required accessories. There is 8 mandatory fallback rules: chassis, cabin, interior, engine, transmission, f_wheel (or f_tire), r_wheel (or r_tire), paint_job and head_light.
- Subfolders: (chassis, cabin, interior, engine, transmission, paint_job, head_light, sound) - defining different parts and accessories of the truck. First 7 folders are needed because of mandatory fallback rules and sound folder is needed for truck mandatory sounds definitions.
- Optional folder: accessory - defining all possible accessories for the truck that user can install in game Upgrade Shop. This folder holds another level of sub folders for separating different accessory types that player can install on the truck and will be listed in Upgrade Shop once player selects proper accessory type. Moreover names of subfolders directly correspond to the names of model locators truck 3D model has to have for ability of having that types of accessories enabled in the game.
