Description

Description:

Returns the value of variable in the variable space assigned to various data types. All available data types combinations:

Primary syntax (String)	Alternative syntax (Array)
Namespace getVariable String Object getVariable String Group getVariable String Team_Member getVariable String Task getVariable String Location getVariable String Control getVariable String (since Arma 3 v1.55.133553) Display getVariable String (since Arma 3 v1.55.133553)	Namespace getVariable Array (since Arma 2 OA v1.60) Object getVariable Array Group getVariable Array Team_Member getVariable Array Task getVariable Array (since Arma 3 v1.67) Location getVariable Array (since Arma 3 v1.67) Control getVariable Array (since Arma 3 v1.55.133553)) Display getVariable Array (since Arma 3 v1.55.133553)

⚠

When variable is set on a Task, it is not actually set on the task itself, but on the FSM attached to the task.
If there is no FSM, getVariable will not work.

Syntax

Syntax:

varspace getVariable name

Parameters:

varspace: Namespace, Object, Display, Control, Group, Location, Task, Team Member, Display, Control

name: String - variable name that was defined in setVariable

Return Value:

Anything or Nothing if the variable doesn't exist

Alternative Syntax

Syntax:

varspace getVariable [name, defaultValue]

Parameters:

varspace: Namespace, Object, Display, Control, Group, Location, Task, Team Member, Display, Control

name: String - Variable name that was defined in setVariable

defaultValue: Anything - Value to return if variable doesn't exist

Return Value:

Anything - current value of the variable or defaultValue if the variable doesn't exist.

Examples

Example 1:

private _variable = myTruck getVariable "myVariable"; // returns nil if "myVariable" is not set

Example 2:

private _variable = myTruck getVariable ["myVariable", 50]; // returns 50 if "myVariable" is not set

Example 3:

Set damage of car0..car5 to 0: for "_i" from 0 to 5 do { _car = missionNamespace getVariable ("car" + str _i); _car setDamage 0; };

Example 4:

myMissionVar = 2015; missionNamespace getVariable "myMissionVar"; // returns 2015

Example 5:

WARNING when using dynamic default values as they always get evaluated: missionNamespace getVariable ["var", 123 call fnc_abc]; // fnc_abc is called every getVariable even if "var" is defined

Example 6:

Get current value of a variable and if it is undefined, define it and get the defined value:private _var = missionNamespace getVariable "varName"; if (isNil "_var") then { missionNamespace setVariable ["varName", 123]; _var = 123; }; // _var here will contain current value of the variable varName

NOTE: Arma 2 ONLY! In Arma 3 this will return default value: Warning: the alternative syntax returns undefined when the varspace is an object and that object is null. Example:
_test = objNull getVariable ["test", "0"]; systemChat _test; Errors because _test is undefined. Tested in A2OA 1.63.131129

You can do typechecking using param: private _myVar = [player getVariable "myVar"] param [0, "", [""]]; and params: [player getVariable "myVar"] params [["_myVar", "", [""]]];
