This page documents the live AutoFlip vehicle recovery module and the separate manual Flip Vehicle action. AutoFlip is a client-started watcher: client init starts Client\Module\AutoFlip\AutoFlip.sqf after WASP base/action setup, and the watcher only evaluates while the player is alive and the game is not over (Client/Init/Init_Client.sqf:647-653; Client/Module/AutoFlip/AutoFlip.sqf:75-100).

Runtime Route

Step	Source-backed behavior
Client startup	Client init starts AutoFlip with [] execVM "Client\Module\AutoFlip\AutoFlip.sqf" (Client/Init/Init_Client.sqf:652-653).
Scan cadence	The watcher sleeps _scanDelay = 3 seconds between scans (Client/Module/AutoFlip/AutoFlip.sqf:9,75-76).
Live guard	A scan runs only when alive player && !gameOver is true (Client/Module/AutoFlip/AutoFlip.sqf:78).
Watched vehicles	The scan adds the player's current vehicle when the player is mounted, then adds mounted vehicles used by units in the player's group while avoiding duplicates (Client/Module/AutoFlip/AutoFlip.sqf:79-99).
Per-vehicle worker	Each watched vehicle is passed to _processVehicle with the current time value (Client/Module/AutoFlip/AutoFlip.sqf:16-20,95-99).

Automatic Flip Gates

The automatic path only starts a stuck timer when every gate below passes.

Gate	Required value	Source
Vehicle exists and is alive	Null or dead vehicles exit immediately.	Client/Module/AutoFlip/AutoFlip.sqf:22-23
Vehicle type	Motorcycles, air vehicles and ships are excluded.	Client/Module/AutoFlip/AutoFlip.sqf:25-26
Tilt	(vectorUp _vehicle) select 2 must be below _tiltLimit = 0.35.	Client/Module/AutoFlip/AutoFlip.sqf:10,28,33,39
Speed	Computed 3D speed must be below _maxSpeed = 2.	Client/Module/AutoFlip/AutoFlip.sqf:13,29-34,40
Height above ground	getPos _vehicle select 2 must be below 3.	Client/Module/AutoFlip/AutoFlip.sqf:35,41
Surface	surfaceIsWater must be false.	Client/Module/AutoFlip/AutoFlip.sqf:36,42
Cooldown	time - WFBE_AutoFlip_LastFlip must be greater than _cooldown = 45.	Client/Module/AutoFlip/AutoFlip.sqf:12,31,37,43
Stuck duration	After a vehicle first passes the gates, it must stay eligible for _stuckDelay = 10 seconds before righting.	Client/Module/AutoFlip/AutoFlip.sqf:11,45-55

Failed tilt, speed, height, water or cooldown gates reset WFBE_AutoFlip_StuckSince to -1, so the ten-second stuck timer restarts after the vehicle leaves and re-enters the eligible state (Client/Module/AutoFlip/AutoFlip.sqf:39-43,45-55).

Righting Operation

Result	Source-backed behavior
Vehicle orientation	AutoFlip sets the vehicle upright with setVectorUp [0,0,1] (Client/Module/AutoFlip/AutoFlip.sqf:57-58).
Vehicle position	AutoFlip keeps the current X/Y position and moves the vehicle to Z 0.5 (Client/Module/AutoFlip/AutoFlip.sqf:57-59).
Vehicle velocity	AutoFlip sets velocity to [0,0,-0.5] after repositioning (Client/Module/AutoFlip/AutoFlip.sqf:60).
Cooldown marker	AutoFlip writes WFBE_AutoFlip_LastFlip with public flag true, then clears WFBE_AutoFlip_StuckSince locally with public flag false (Client/Module/AutoFlip/AutoFlip.sqf:61-62).
Client notification	The local watcher resolves the vehicle display name, localizes STR_WF_INFO_AutoFlip_Righted, falls back to an English template if the localization is empty, and sends systemChat (Client/Module/AutoFlip/AutoFlip.sqf:64-68; stringtable.xml:9540-9547).
Debug logging	With WF_Debug, AutoFlip logs both the initial tracking state and the final righting event (Client/Module/AutoFlip/AutoFlip.sqf:50-52,70-72).

Manual Flip Action

Manual Flip Vehicle is a separate on-demand path. It is added to tanks and cars from Init_Unit.sqf, appears only when the target's vectorUp Z value is below 0.35 and the target is within 10 meters of the player, and calls WASP\actions\FlipVehicle.sqf (Common/Init/Init_Unit.sqf:71-84).

Surface	Automatic AutoFlip	Manual Flip Vehicle
Startup	Starts from client init and keeps looping (Client/Init/Init_Client.sqf:652-653; Client/Module/AutoFlip/AutoFlip.sqf:75-100).	Added as a per-vehicle action on tank and car init paths (Common/Init/Init_Unit.sqf:71-84).
Target selection	Watches the player's vehicle plus vehicles used by units in the player's group (Client/Module/AutoFlip/AutoFlip.sqf:79-99).	Runs on the addAction target vehicle (WASP/actions/FlipVehicle.sqf:9-12).
Delay and cooldown	Requires the stuck timer and cooldown gates (Client/Module/AutoFlip/AutoFlip.sqf:11-12,45-55).	The script comment says it bypasses AutoFlip's stuck timer and cooldown, and the script only checks null/alive before righting (WASP/actions/FlipVehicle.sqf:1-19).
Righting technique	Uses setVectorUp, setPos and setVelocity (Client/Module/AutoFlip/AutoFlip.sqf:57-60).	Uses the same setVectorUp, setPos and setVelocity shape (WASP/actions/FlipVehicle.sqf:16-19).

Do not confuse either vehicle-righting path with Valhalla low gear. Valhalla's low-gear actions are adjacent tank/car actions that call Client\Module\Valhalla\LowGear_Toggle.sqf and gate on driver/vehicle state, not tilt recovery (Common/Init/Init_Unit.sqf:71-84).

Practical Limits

Limit	Source-backed meaning
Not map-wide cleanup	AutoFlip only scans the player's mounted vehicle and mounted vehicles used by units in the player's group, not every abandoned vehicle on the map (Client/Module/AutoFlip/AutoFlip.sqf:79-99).
Not for air, ships or motorcycles	The automatic worker exits for Motorcycle, Air and Ship, while the manual action is only attached in the tank and car init blocks (Client/Module/AutoFlip/AutoFlip.sqf:25-26; Common/Init/Init_Unit.sqf:71-84).
Not a water recovery feature	The automatic worker exits when surfaceIsWater is true (Client/Module/AutoFlip/AutoFlip.sqf:36,42).
Local notification only	The notification comment says it is sent only to the client whose watcher actually rights the vehicle, and the implementation uses systemChat inside that local script (Client/Module/AutoFlip/AutoFlip.sqf:64-68).
