Documentation/Engine/Units/accessory truck data

The accessory_truck_data unit class defines basic information, cameras, fallback rules, and required accessories for the player's truck. Units of this type are defined in /def/vehicle/truck/<brand.model>/data.sii.

Attributes

Many common attributes are inherited from accessory_data. Required attributes are bolded.

Name	Type	Default Value	Description
info	array<string>		Two info members are typically defined for accessory_truck_data: info[]: "@@brand_peterbilt@@" // The truck brand info[]: "@@series_peterbilt_579@@" // The truck model
require	array<token>		Accessory types which should be required, regardless of the vehicle configuration, should be defined in accessory_truck_data. For more information, see accessory_data.
behind_camera	link_ptr		The unit name of the camera to use for the orbit (2) view. Typically camera.behind.basic.
interior_camera	link_ptr		The unit name of the camera to use for the interior (1) view. Typically camera.interior.<brand>.<model>.
interior_camera_oculus	link_ptr		The unit name of the camera to use for the interior (1) view when using a head-mounted display. Typically camera.interior.<brand>.<model>.oculus.
window_camera	link_ptr		The unit name of the camera to use in the lean-out (5) view. Typically camera.window.basic.
bumper_camera	link_ptr		The unit name of the camera to use in the bumper (6) view. Typically camera.bumper.basic.
cabin_camera	link_ptr		The unit name of the camera to use for the cabin-top (4) view. Typically camera.cabin.basic, placed at the cam_cabin* locator of the active cabin accessory variant.
wheel_camera	link_ptr		The unit name of the camera to use in the wheel (7) view. Typically camera.wheel.basic.
top_camera	link_ptr		The unit name of the camera to use for the overhead (3) view. Typically camera.top.basic.
top_fixed_camera	link_ptr		Typically unused.
tv_camera	link_ptr		The unit name of the camera to use in TV (8) view. Typically camera.tv.basic.
predefined_tv_camera	link_ptr		Typically unused.
side_camera	link_ptr		Typically unused.
wander_camera	link_ptr		The unit name of the camera to use in wander mode. Typically camera.wander. The player typically won't encounter this mode as it is primarily used for testing.
debug_camera	link_ptr		The unit name of the camera to use for the developer/fly camera (0). Typically camera.debug.
fallback	array<string>		Each member contains a specially-formatted string which defines an accessory type (token) and the relative path to an SII file with a safe fallback accessory defined. So a fallback rule for chassis may look like fallback[]: "chassis|4x2.sii" which would call on /def/vehicle/truck/<make.model>/chassis/4x2.sii if there is ever a problem with the vehicle's currently assigned chassis accessory that makes it invalid or unloadable. Accessories in the accessory folder are handled somewhat specially. For example, a rule for steering_w looks like fallback[]: "accessory|steering_w/shape1.sii". Note: There are 15 required fallback rules: chassis, cabin, engine, transmission, f_tire, f_disc, f_hub, f_nuts, r_tire, r_disc, r_hub, r_nuts, head_light, paint_job, interior. It is generally advisable to include a rule for steering_w if the truck has interchangeable steering wheels.

Pin Overrides (Added in 1.40)

The following array attributes are used to override the location, appearance, and orientation of accessory pins in the truck configuration scene. Their usage is the same as the identically named attributes in the ui_truck_scene_config unit, such that one member of each array is used to override the behavior of each pin. Pin overrides defined in accessory_truck_data will supersede the data in ui_truck_scene_config for the associated truck.

Name	Type	Description
pin_group	array<token>	The name of the accessory group for each pin override
pin_look	array<token>	The appearance of the accessory pin to use – typically custom_acc
pin_offset	array<float3>	Vector to offset the accessory pin from the locator
pin_dir	array<float3>	Vector to set the direction of the pin (independent of locator orientation)
pin_dir_uk	array<float3>	Vector to set the direction of the pin for right-hand drive (independent of locator orientation). This attribute is typically omitted in ATS.
double_sided	array<bool>	When true, the pin will be duplicated and mirrored across the truck's X-axis.

In this first example, the pin for the sideskirt accessory is offset 1 m to the left of the locator (-X), and pointed to the left as well (-X). It will also be drawn 1 m to the right of the locator, pointed to the right.

	pin_group[]: 	sideskirt
	pin_look[]: 	custom_acc
	pin_offset[]: 	(-1, 0, 0)
	pin_dir[]: 	(-1, 0, 0)
	pin_dir_uk[]: 	(-1, 0, 0)
	double_sided[]:	true

In this example, the pin for the exhaust accessory will be drawn at the locator (no offset), and will be pointed 45° to the rear left of the truck. It will also be drawn 45° to the rear right of the truck. This has the effect of making the pin completely visible from both sides and the rear of the vehicle.

	pin_group[]: 	exhaust
	pin_look[]: 	custom_acc
	pin_offset[]: 	(0, 0, 0)
	pin_dir[]: 	(-1, 0, 1)
	pin_dir_uk[]: 	(-1, 0, 1)
	double_sided[]:	true
