NOEDITSECTION Magic variables are engine-maintained variables that serve a specific purpose within a given scope and are often used by the engine to provide data to a script or code fragment.
They are usually no longer present after leaving the scope (e.g. after code execution or after a forEach-statement).
_this
Used to make the arguments of a script call (call, exec, execVM, spawn) visible and accessible to the script. Also used by Event Handlers to provide parameters.
_x
Represents the current element during iteration with apply, count, configClasses, configProperties, findIf, forEach and select.
_y (Arma 3 v2.02)
Iterating over a HashMap with forEach will return the key as _x and the value as _y.
_exception (Armed Assault v1.00)
Exception handling using a try-catch-statement declares this variable which contains details about the thrown exception in the try-block.
_fnc_scriptName (Arma 3 v1.00)
Note
Not engine-maintained, but added by
functions_f/initFunctions.sqf– see scriptName.
Within a Function, the TAG_fnc_functionName function name (e.g. "myTag_fnc_myFunction").
_fnc_scriptNameParent (Arma 3 v1.00)
Note
Not engine-maintained, but added by
functions_f/initFunctions.sqf– see scriptName.
Within a Function, the name of the function that called the current function (same as _fnc_scriptName if the function was not called by another function).
_forEachIndex (Arma 2: Operation Arrowhead v1.55)
Represents the (zero-based) index of a forEach- / forEachReversed-loop.
_self (Arma 3 v2.14)
Available in HashMapObject methods. Contains the HashMapObject instance that the method was invoked on (see createHashMapObject).
_thisArgs (Arma 3 v2.04)
Additional Event Handler arguments available with addMissionEventHandler.
_thisEvent (Arma 3 v2.06)
The name of the Event added with addEventHandler, addMPEventHandler, addMissionEventHandler,addUserActionEventHandler, ctrlAddEventHandler and displayAddEventHandler, as well as for config types EHs.
_thisEventHandler (Arma 3 v1.64)
The index for Event Handlers added with addEventHandler, addMPEventHandler, addMissionEventHandler, addUserActionEventHandler, ctrlAddEventHandler and displayAddEventHandler.
_thisFSM (Arma 3 v1.54)
The FSM ID for FSMs executed with execFSM.
_thisScript (Arma 3 v1.54)
The Script Handle of a script started with execVM, call or spawn.
_thisScriptedEventHandler (Arma 3 v1.68)
The index for Scripted Event Handlers added with BIS_fnc_addScriptedEventHandler.
_time
Warning
SQS only.
The time elapsed since the script started running.
this
- Addon Config Files (e.g. UserActions, onInit, etc.): The object to which the entry belongs.
- Dialogs: The player unit that activated control (e.g. via mouseEnter). false if non-activated.
- Object Init Fields: The object to which the init field belongs.
- Triggers:
- Waypoints:
- Condition, On Activation and On Deactivation: The group leader that completed the waypoint (or the driver, if the waypoint is assigned to a vehicle).
thisList
- Triggers:
- Accessible in the Condition, On Activation and On Deactivation code.
- Defines an array of objects that have been detected by the trigger (same as what is returned by the list command).
- Seems to be undefined in the On Deactivation expression and should not be used. It will either be an empty array, or possibly the contents of a different trigger.
- Waypoints:
- Accessible within the Condition or On Activation code.
- Defines an array containing all group members that completed the waypoint.
thisTrigger
Refers to the trigger object itself - accessible within the Condition, On Activation and On Deactivation code.
thisActivator (Arma 3 v2.22)
Refers to an Object, which activated this trigger. Default: the trigger Object itself.
