Changes

There was added A new array attribute, '''''steerable_axlessteerable_axle[]''''' , was added to [[Documentation/Engine/Units/accessory_chassis_data|chassis data that ]]. It controls which axle is axles are steerable instead of locator names. Locator names right now define only the wheel type (model) dependency. Semantics The semantics of '''''steerable_axlessteerable_axle[]''''' is the same as '''''powered_axlespowered_axle[]''''' or '''''liftable_axlesliftable_axle[]''''' respectively. If not defined its default is guessed , the values are inferred from the vehicle type (. By default, a trailer has will have no steerables, steerable axles and a truck has will have its first axle steerable).

Array The '''''powered_wheelspowered_wheel[]''''' array is not no longer supported for defining powered wheels definition anymore, its just and is now ignored. Use The '''''powered_axlespowered_axle[]''''' array must now be used properly.

With new feature of trailer cables, there is also new accessory type '''accessory_addon_trailer_cables_data'''that can be used on truck and trailer (for doubles, triples etc.). This accessory type can be used only in conjunction with accessory named: '''trlr_cables''' or cables won't be present in the game. New accessory type besides normal vehicle accessory attributes, has an array attribute of owner pointers of type '''physics_trailer_cable_data'''.

==== Physics trailer New accessory type, besides normal vehicle accessory attributes, has an array attribute of owner pointers of type '''physics_trailer_cable_data'''. This array defines what kind and how many cables will be used on vehicle. Each cable data ====pointer from array has to be defined inside same SiiNunit.
