The trailer_def unit class acts as an intermediary between cargo_data and trailer units. Units of this type are usually defined in /def/cargo/<cargo_name>/<trailer_name>.sii, corresponding to def/cargo/<cargo_name>.sii. They define which trailer configuration to enable for the cargo, the cargo's mass for that trailer configuration, how that mass is distributed/placed on the trailer and its slave units, and where the configuration is permitted.

Attributes

Name Type Default Value Description
trailer string The unit name of the trailer unit to be enabled for the cargo. This attribute can safely refer to units which aren't present.
mass float The mass of the cargo for this trailer configuration in kilograms (kg).
volume_factor float 1.0 The amount of cargo relative to what the cargo definition is nominally based on. This allows the game economy to scale the pay per distance for trailers of different sizes hauling the same cargo. Added in 1.28.

Note: For example, if the cargo definition is nominally based on a 53ft trailer, the volume_factor for a 40ft trailer might be approximately 0.75 (40÷53).

length uint 20 The approximate length of the trailer combination in meters. When generating a job this is compared against the allowed_trailer_length of the source and destination depot prefabs to determine whether this trailer_def is suitable for the job. Added in 1.28.
country array<token> Each member is a country (state in ATS) where this trailer_def will be suitable for generated jobs. Both the origin and destination of a job must be in the country array for the trailer_def to be suitable for it. If unset, then the trailer_def is suitable in all countries. Added in 1.28.
cog_offset array<float3> Each member defines the offset of the cargo center of gravity from the calculated value for each trailer in the trailer configuration, starting with the master trailer and iterating through the slave trailers. (X, Y, Z) corresponds to lateral, vertical, and longitudinal offsets respectively.
cargo_mass_ratio array<float>
cargo_mass_ratio: 1
cargo_mass_ratio[0]: 1
Each member defines how much of the cargo mass and forces are borne by each trailer in the trailer configuration, starting with the master trailer and iterating through the slave trailers.
