Documentation/Engine/Truck Interior Animations and IDs

Interior Animations

The movement of various things in the truck interior is controlled by program-driven animations ( *_anim ). For each animation, the range is set by the *_anim_min and *_anim_max values. As most animations expect a range from 0 to 1, these are also the default values. If an animation expects any other value range, it will be stated below.

Special Animations

Attribute Name	Function	Behavior	Notes
wheel_anim	Steering wheel	0 - left full lock 0.5 - center 1 - right full lock	(Obsolete in 1.42) For best results, each keyframe should be less than 45° The steering wheel bone should be named steering_w for compatibility with interchangeable steering wheels.
wheel_updown_anim	Steering column tilt adjustment	0 - lowest setting 1 - highest setting	The default position is set by wheel_updown_anim_default
wheel_frontback_anim	Steering column telescope adjustment	0 - fully retracted 1 - fully extended	The default position is set by wheel_frontback_anim_default
wiper_anim	Windshield wipers	0→1 is a full wipe cycle (from park to full travel and back to park)	The keyframes at 0 and 1 should match.
gadget_anim		0→1 is a full animation cycle (animation will be played as a continuous loop)	This animation is played in a loop while the truck's ignition/electricity is on.
left_window_anim	Left window up/down animation	0 - closed 1 - open	Controlled with window up/down controls.
right_window_anim	Right window up/down animation	0 - closed 1 - open	Controlled with window up/down controls.

Stick Animations

Attribute Name	Function	Behavior	Notes
blinker_anim	Turn signal control lever	0 - left indicator active 0.5 - rest position 1 - right indicator active
lights_anim	Headlight control	0 - lights off 0.5 - parking/clearance lights on 1 - headlights on
high_beam_anim	High beam headlight control	0 - rest position 1 - high beams on
light_horn_stick_anim	Light/city horn button	0 - rest position 1 - light horn being applied
wiper_stick_anim	Windshield wiper control	0 - off 1 - maximum speed	This animation is interpolated based on the total number of wiper speeds. For example, if there are two additional wiper speeds (delays), 0.33 would correspond with the first and 0.67 with the second delay definition.
parking_stick_anim	Parking brake control	0 - parking brake released 1 - parking brake applied	North America: Whether 'in' or 'out' is the applied state will depend on the truck – make sure that the animation matches the label on the valve or you will look like a goof. The typical usage is for 'push to release' systems where the 0.0 state is 'in' and the 1.0 state is 'out'.
			Europe:
flasher_4way_anim	Four-way flasher (hazard light) control	0 - rest position 1 - hazard lights are active	For a button, the “depressed” state would be 0.5 to make the button press and rebound for both activation and deactivation
engine_start_anim	Ignition and starting controls	0 - off 0.33 - electricity on 0.67 - engine on 1 - engine starting
beacon_anim	Beacon on/off switch	0 - beacon off 1 - beacon on
trailer_air_stick_anim	Trailer air supply valve	0 - trailer disconnected 1 - trailer connected	This is directly tied to whether a trailer is connected to the truck or not. Typical usage is for a 'push to supply' type, so the valve is 'out' in the 0.0 state and 'in' in the 1.0 state
trailer_brake_stick_anim	Trailer brake hand valve (sometimes called the 'spike')	0 - rest position 1 - trailer brake hand valve fully applied	Do not confuse this with the trailer supply valve - the hand valve is used (rarely) to apply only the trailer brakes in a controlled manner
retarder_stick_anim	Retarder control	0 - off 1 - maximum setting
engine_brake_stick_anim	Engine brake control	0 - off 1 - maximum setting	Added in 1.38
auto_transmission_stick_anim	Automatic transmission gear selector	0 - reverse 0.5 - neutral 1 - drive
lift_axle_stick_anim	Lift axle switch/control
differential_lock_stick_anim	Differential lock switch/control	0 - disengaged 1 - engaged	Added in ETS2 1.27/ATS 1.6
left_window_stick_anim	Left window switch/control	0 - closing 0.5 - rest position 1 - opening
right_window_stick_anim	Right window switch/control	0 - closing 0.5 - rest position 1 - opening

Gauge animations

This set of animations handles analog gauges. The related *_min and *_max attributes set the values that the start and end of the animation correspond to. Where the simulated value exceeds the min/max attribute, the animation is clamped.

Note: All *_psi_* attributes have been renamed to *_pressure_* as of ETS2 1.27/ATS 1.6. This is to reflect the change to bar (atmospheres) as the working pressure unit instead of psi.

Indicator animations

These animations are not interpolated from 0 to 1. Instead they have only 2 states: switched off (0) and switched on (1), so these animations should have only 2 key frames. All indicator animations are triggered during the start-up electrical check, as well as for their particular functions.

Dashboards IDs

Screen of dashboard computers uses our UI library and shows thus UI elements. Each element has unique ID and can be used only once (due to caching). Most of fields can be used as two parameter template - value and unit, both are used accordingly to current game options.

Note: In 1.49 text bars were changed to ui_text_bar element. No additional data is needed now, all is kept in regular members (vertical, min_size, max_size, min_value, max_value).

Old system (pre 1.49) used secondary text fields. Data for bars were entered in format "H~~0~~130", H means the bar is horizontal (or V for vertical), leftmost position represents value 0, rightmost position represents value 130. Empty text defaults to "H~~0~~1".
