The accessory_addon_tank_data unit class is used for adding accessory based tank data container. For player trucks, units of this type are usually defined in /def/vehicle/truck/<brand.model>/accessory/tank/*.sii and valid unit names end in .tank. This unit type was added in 1.41.

Many common attributes are inherited from accessory_addon_data.

Model

A valid trailer cables accessory model must have the following:

• Some visible geometry (models cannot contain only locators)
• Attachment locators for each member defined in the cables array, where the truck plug model will be placed. The locator names are defined by each trailer_cable_data unit's locator_prefix attribute.

It may additionally make use of the following:

• Rest locators for each defined cable where the trailer plug model will be placed when there is no trailer connected (otherwise the cable will not be drawn/simulated when there is no trailer connected). The locator names are defined by each trailer_cable_data unit's rest_locator_prefix attribute.
• Special part names are displayed only during particular states:
  • cables_off is displayed only when no trailer is attached
  • cables_on is displayed only when a trailer is attached
