Basic Event Handlers
The object-based Event Handler is always executed on the computer where it was added.
Commands:
Standard
AnimChanged
GAGlobal
Triggered every time a new animation is started. This EH is only triggered for the 1st animation state in a sequence.
- unit: Object - object the event handler is assigned to
- anim: String - name of the anim that is started
AnimDone
GAGlobal
Triggered every time an animation is finished. Triggered for all animation states in a sequence.
- unit: Object - object the event handler is assigned to
- anim: String - name of the anim that has been finished
AnimStateChanged
GAGlobal
Triggered every time an animation state changes. Triggered for all animation states in a sequence.
- unit: Object - object the event handler is assigned to
- anim: String - name of the anim that has been started
CargoLoaded
GAGlobal
Triggered when a vehicle is loaded into another vehicle (ViV).
It can be added to either the transport vehicle, or the cargo vehicle, and will fire for both cases.
- parentVehicle: Object - the transport (parent) vehicle
- cargoVehicle: Object - the cargo (child) vehicle
CargoUnloaded
GAGlobal
Triggered when a vehicle is unloaded from another vehicle (ViV).
It can be added to either the transport vehicle, or the cargo vehicle, and will fire for both cases.
- parentVehicle: Object - the transport (parent) vehicle
- cargoVehicle: Object - the cargo (child) vehicle
ContainerClosed
GAGlobal
Triggers when player finished accessing cargo container.
This event handler is similar to InventoryClosed EH, but needs to be assigned to the container rather than the player.
Note: will trigger only for the unit opening container.
ContainerOpened
GAGlobal
Triggers when cargo container is accessed by player.
This event handler is similar to InventoryOpened EH, but needs to be assigned to the container rather than the player and cannot be overridden.
Note: will trigger only for the unit opening container.
ControlsShifted
GAGlobalLELocal
Triggers when control of a vehicle is shifted (pilot->co-pilot, co-pilot->pilot), usually when user performs an action such as TakeVehicleControl, SuspendVehicleControl, UnlockVehicleControl, LockVehicleControl, or when enableCopilot command is used. This event handler will always fire on the PC where action is triggered as well as where the vehicle is local at the time. When control of the vehicle is shifted, the locality of the vehicle changes to the locality of the new controller. For example, if helicopter is local to the server and co-pilot takes controls, the helicopter changes locality to co-pilot PC.
This means that if "ControlsShifted" EH was added on both server and client, "Take Controls" action will trigger EH on both, client and server PC, but subsequent co-pilot "Release Controls" action will trigger only on co-pilot's PC, because vehicle will be local to co-pilot at this point. There is also a slightly better mission version of ControlsShifted event handler.
- vehicle: Object - vehicle which controls were shifted
- activeCoPilot: Object - co-pilot unit which controls vehicle after this event. objNull if co-pilot is not controlling the vehicle
- oldController: Object - unit who controlled vehicle before this event
Dammaged
GAGlobal
Triggered when the unit is damaged. In ArmA works with all vehicles not only men like in OFP.
Notes:
- The typo is "intentional": it is Dammaged with two "m".
- If simultaneous damage occured (e.g. via grenade) EH might be triggered several times.
- The Dammaged EH will not necessarily fire if only minor damage occurred (e.g. firing a bullet at a tank), even though the damage increased.
- unit: Object - object the event handler is assigned to
- hitSelection: String - name of the selection where the unit was damaged
- damage: Number - resulting level of damage
1.68 hitPartIndex: Number - hit index of the hit selection- 1.68 hitPoint: String - hit point Cfg name

Explosion
GAGlobal
Triggered when a vehicle or unit is damaged by a nearby explosion.

- damage: Number - damage inflicted to the object
2.10 source: Object - may be objNull in some cases
Fired
GAGlobal
Triggered when the unit fires a weapon.
This EH will not trigger if a unit fires out of a vehicle. For those cases an EH has to be attached to that particular vehicle.
When "Manual Fire" is used, the gunner is objNull if gunner is not present or the gunner is not the one who fires.
To check if "Manual Fire" is on, use isManualFire. The actual shot instigator could be retrieved with getShotParents command.

(Exception(s): the Throw weapon wont broadcast the FiredNear event).
When "Manual Fire" is used, the gunner is objNull if gunner is not present or the gunner is not the one who fires.
To check if "Manual Fire" is on, use isManualFire. The actual shot instigator could be retrieved with getShotParents command.

GestureDone
GAGlobal
Triggered every time a gesture is finished.
- unit: Object - object the event handler is assigned to
- gesture: String - name of the gesture that has been finished
GetIn
GAGlobal
Triggers when a unit enters the vehicle to which this EH has been added. This EH is triggered by moveInXXXX commands and "GetInXXXX" actions, but not upon a seat change within the same vehicle.
In vehicles with multi-turret setup, entering any turret will show "gunner" for position.
- vehicle: Object - vehicle the event handler is assigned to
- role: String - can be either "driver", "gunner" or "cargo"
- unit: Object - unit that entered the vehicle
- 1.36 turret: Array - turret path
GetInMan
GAGlobal
Triggers when a unit enters a vehicle. Similar to "GetIn" but must be assigned to a unit and not vehicle.
Persistent on respawn if assigned where unit was local. This EH is triggered by moveInXXXX commands and "GetInXXXX" actions.
- unit: Object - unit the event handler is assigned to
- role: String - can be either "driver", "gunner" or "cargo"
- vehicle: Object - vehicle the unit entered
- turret: Array - turret path
GetOut
GAGlobal
Triggers when a unit gets out from the vehicle to which this EH has been added.
This EH is triggered by moveOut, "GetOut" & "Eject" actions, if an alive crew member disconnects or is deleted, but not upon a seat change within the same vehicle.
- vehicle: Object - vehicle the event handler is assigned to
- role: String - can be either "driver", "gunner" or "cargo"
- unit: Object - unit that left the vehicle
- 1.36 turret: Array - turret path
GetOutMan
GAGlobal
Triggers when a unit exits a vehicle. Similar to "GetOut" but must be assigned to a unit and not vehicle.
Persistent on respawn if assigned where unit was local. This EH is triggered by moveOut and "GetOut" & "Eject" actions.
- unit: Object - unit the event handler is assigned to
- role: String - can be either "driver", "gunner" or "cargo"
- vehicle: Object - vehicle that the unit left
- turret: Array - turret path
HandleDamage
GAGlobal
Triggers when the unit is damaged and fires for each damaged selection separately
Note: Currently, in Arma 3 v1.70 it triggers for every selection of a vehicle, no matter if the section was damaged or not). Works with all vehicles.
This EH can accept a remote unit as argument however it will only fire when the unit is local to the PC this event handler was added on.
For example, you can add this event handler to one particular vehicle on every PC.
When this vehicle gets hit, only EH on PC where the vehicle is currently local will fire.
If code provided returns a numeric value, this value will overwrite the default damage of given selection after processing. Return value of 0 will make the unit invulnerable if damage is not scripted in other ways (i.e using setDamage and/or setHit for additional damage handling). If no value is returned, the default damage processing will be done. This allows for safe stacking of this event handler. Only the return value of the last added "HandleDamage" EH is considered.
Notes:
- Multiple "HandleDamage" EHs can be added to the same unit. If multiple EHs return damage value for custom damage handling, only last returned value will be considered by the engine.
EHs that do not return value can be safely added after EHs that do return value.
- You can save the last event as timestamp (diag_tickTime) onto the unit, as well as the current health of the unit/its selections, with setVariable and query it on each "HandleDamage" event with getVariable to define a system how to handle the "HandleDamage" event.
- "HandleDamage" will continue to trigger even if the unit is already dead.
- "HandleDamage" is persistent. If you add it to the player object, it will continue to exist after player respawned.
- "HandleDamage" can trigger "twice" per damage event. Once for direct damage, once for indirect damage (explosive damage). This can happen even in the same frame, but is unlikely.
Additional Celery's explanation (Updated by ShadowRanger for Arma 3).
- unit: Object - object the event handler is assigned to
- selection: String - name of the selection where the unit was damaged.
- "" for overall structural damage
- "?" for unknown selections
- damage: Number - resulting level of damage for the selection
- source: Object - the source unit that caused the damage
- projectile: String - classname of the projectile that caused inflicted the damage. ("" for unknown, such as fall damage)
- 1.50 hitPartIndex: Number - hit part index of the hit point, -1 otherwise
- 1.66 instigator: Object - person who pulled the trigger
- 1.68 hitPoint: String - hit point Cfg name
- 2.12 directHit: Boolean - false for fall damage
HandleHeal
GAGlobal
Triggered when unit starts to heal (player using heal action or AI heals after being ordered).
Triggers only on PC where EH is added and unit is local.
If code returns false, engine side healing follows.
Return true if you handle healing in script, use AISFinishHeal to tell engine that script side healing is done.
See also lifeState and setUnconscious commands.
NOTE: This Event Handler is broken but somewhat usable.
When attached to a unit it will fire when medic action is started (not finished!) on the unit.
_this select 0 will be the unit itself, _this select 1 will be the healer.
The 3rd param will always be false and neither returning true nor using AISFinishHeal will have any effect on the engine default healing behaviour.
If unit walks away from the healer during healing action, the heal will not finish but there is no way to detect this within "HandleHeal" framework.
This code will fix unit to 100% health after self-use of medpack:
HandleIdentity
GAGlobal
Triggered whenever an entity is created. Can be used in scripts if EH is added immediately after unit is created in unscheduled environment.
Doesn't trigger for editor placed units. Does not work in Multiplayer. If EH scope returns true, the default engine identity application is overridden.
- unit: Object - object the event handler is assigned to
HandleRating
LALocal
Triggered when engine adds rating to overall rating of the unit, usually after a kill or a friendly kill.
If EH code returns Number, this will override default engine behaviour and the resulting value added will be the one returned by EH code.
HandleScore
GAGlobalSEServer
Triggered when engine adds score to overall score of the unit, usually after a kill.
If the EH code returns Nothing or true, the default engine scoreboard update (score, vehicle kills, infantry kills, etc) is applied, if it returns false, the engine update is cancelled. To add or modify score, use addScore and addScoreSide commands.
For remote units like players, the event does not persist after respawn, and must be re-added to the new unit.
NOTE: MP only.
- unit: Object - object the event handler is assigned to
- object: Object - object for which score was awarded
- score: Number - score to be added
Hit
LALocal
Triggered when the unit is hit/damaged.
Is not always triggered when unit is killed by a hit.
Most of the time only the killed event handler is triggered when a unit dies from a hit.
The hit EH will not necessarily fire if only minor damage occurred (e.g. firing a bullet at a tank), even though the damage increased.
Does not fire when a unit is set to allowDamage false.
- unit: Object - object the event handler is assigned to
- source: Object - object that caused the damage – contains unit in case of collisions
- damage: Number - level of damage caused by the hit
- 1.66 instigator: Object - person who pulled the trigger
HitPart
GAGlobal
Runs when the object it was added to gets injured/damaged.
It returns the position and component that was hit on the object within a nested array, this is because the model may have more than one selection name for the hit component
(i.e. a single piece of geometry can be simultaneously part of multiple, overlapping named selections).
While you can add "HitPart" handler to a remote unit, the respective addEventHandler command must be executed on the shooter's PC and will only fire on shooter's PC as well. The event will not fire if the shooter is not local, even if the target itself is local. Additionally, if the unit gets damaged by any means other than ammunition or explosions, such as fall damage and burning, "HitPart" will not fire. Because of this, this event handler is most suitable for when the shooter needs feedback on his shooting, such as target practicing or hitmarker creation.
This EH returns array of sub-arrays [[...],[...], ... [...]]. Each sub-array contains data for the part that was hit as usually multiple parts are hit at the same time (see HitPart_Sample). The structure of each sub-array is listed below.
- target: Object - object that got injured/damaged
- shooter: Object - unit or vehicle that inflicted the damage. If injured by a vehicle collision, the target itself is returned, or in case of explosions, the null object.In case of explosives that were planted by someone (e.g. satchel charges), that unit is returned
- projectile: Object - object that was fired
- position: Array format PositionASL - position the bullet impacted
- velocity: Vector3D - 3D speed at which the bullet impacted
- selection: Array - array of Strings with named selection of the object that were hit
- ammo: Array - ammo info: [hit value, indirect hit value, indirect hit range, explosive damage, ammo class name]; Or, in case of a vehicle collision: [impulse value, 0, 0, 0]; hit and damage values are derived from the projectile's CfgAmmo class, and do not match the actual damage inflicted, which is usually lower due to armor and other factors
- vector: Vector3D - vector that is orthogonal (perpendicular) to the surface struck. For example, if a wall was hit, vector would be pointing out of the wall at a 90 degree angle
- radius: Number - radius (size) of component hit
- surface: String - surface type struck
- direct: Boolean - true if object was directly hit, false if it was hit by indirect/splash damage

Triggered whenever an entity is created. Cannot be used in scripts, only inside class Eventhandlers in config.
e.g:
init = "params ['_entity'];";

Triggered when unit opens inventory. Said unit can be non-local when adding the EH, but must be local for the EH to trigger. End EH main scope with true to override the opening of the inventory in case you wish to handle it yourself:
- unit: Object - object the event handler is assigned to
- targetContainer: Object - connected container or weaponholder
- 1.66 secondaryContainer: Object - second connected container or weaponholder or objNull
Killed

Note: Doesn't trigger if player switches off auto-pilot. Canceled is spelled with one L
- plane: Object - object the event handler is assigned to
- airportID: Number or Object - ID of the airport or aircraft carrier object (-1 no airport)
- isCarrier: Boolean - true if landing on aircraft carrier
Local
GAGlobal
Triggers when locality of object in MP is changed. The event handler only triggers on the computers that are directly involved in change of locality.
So if EH is added to every computer on network, it will only trigger on 2 computers, on the computer that receives ownership of the object (new owner), in which case _this select 1 will be true,
and on the computer from which ownership is transferred (old owner), in which case _this select 1 will be false.
- entity: Object - the object that changed locality

Multiplayer Event Handlers
Global object event handler, executed on every connected machine.
Commands:
MPHit
GAGlobalGEGlobal
Triggered when the unit is hit/damaged. EH can be added on any machine and EH code will trigger globally on every connected client and server.
This EH is clever enough to be triggered globally only once even if added on all clients or a single client that is then disconnected, EH will still trigger globally only once.
Is not always triggered when unit is killed by a hit. Most of the time only the Killed event handler is triggered when a unit dies from a hit. The hit EH will not necessarily fire if only minor damage occurred (e.g. firing a bullet at a tank), even though the damage increased. Can also trigger several times for an explosion (direct and indirect damage). Does not fire when a unit is set to allowDamage false. However it will fire with "HandleDamage" EH added alongside stopping unit from taking damage (unit addEventHandler ["HandleDamage", { 0 }];. Will not trigger once the unit is dead.
Note: call a function from the MPHit EH code space rather than defining the full code in there directly. The reason is the code space will be transferred over network on each event activation - so keep the data as small as possible!
- unit: Object - object the event handler is assigned to
- causedBy: Object - object that caused the damage. Contains the unit itself in case of collisions.
- damage: Number - level of damage caused by the hit
- 1.66 instigator: Object - person who pulled the trigger
MPKilled
GAGlobalGEGlobal
Triggered when the unit is killed. EH can be added on any machine and EH code will trigger globally on every connected client and server.
This EH has a safeguard measure so that even if it's added on all clients or a single client that is then disconnected, EH will still trigger globally only once per client.
- unit: Object - object the event handler is assigned to
- killer: Object - object that killed the unit. Contains the unit itself in case of collisions
- 1.66 instigator: Object - person who pulled the trigger
- 1.68 useEffects: Boolean - same as useEffects in setDamage alt syntax
MPRespawn
GAGlobalLELocal
Triggered when a unit, it is assigned to, respawns. This EH does not work as one would expect MP EH should work like.
It is only triggered on one machine where the unit it was assigned to is local.
The only difference between Respawn and MPRespawn is that MPRespawn can be assigned from anywhere while Respawn requires the unit to be local.
MPRespawn EH expects the EH code to return array in format of Position, which will be used to place respawned unit at desired coordinates.
For example: player addMPEventHandler ["MPRespawn", { [1234, 1234, 0] }]; will place player at [1234,1234,0] immediately on respawn.
