Description

Description:

Return the value of variable in the variable space assigned to various data types. In case of Alt Syntax usage in Arma 3, the default value will be returned if:

• Requested variable is either undefined or nil
• Variable namespace is null (objNull, grpNull, etc.)

All available data types combinations:

• Namespace getVariable String
• Namespace getVariable Array (since a2 1.60)
• Object getVariable String
• Object getVariable Array
• Group getVariable String
• Group getVariable Array
• Team_Member getVariable String
• Team_Member getVariable Array
• Task getVariable String
• Task getVariable Array (Since Arma 3 v1.67)
• Location getVariable String
• Location getVariable Array (Since Arma 3 v1.67)
• Control getVariable String (since Arma 3 v1.55.133553)
• Control getVariable Array (since Arma 3 v1.55.133553)
• Display getVariable String (since Arma 3 v1.55.133553)
• Display getVariable Array (since Arma 3 v1.55.133553)

When variable is set on Task, it is not actually set on task itself, but on FSM attached to the task. So 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, defaultValue]: Array

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:

_thePublicVariable = _myTruck getVariable "myPublicVariable";

Example 2:

_aLocalVariable = _myTruck getVariable ["myLocalVariable", ["Not set", _var]] select 1;

Example 3:

for "_i" from 0 to 5 do { _car = missionNamespace getVariable ("car" + str _i); _car setDamage 0; }; Sets damage of car0, car1, ..., car5 to 0.

Example 4:

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

Example 5:

WARNING when using dynamic default value: missionNamespace getVariable ["var", 123 call fnc_abc]; /// fnc_abc is always called even when 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","",[""]]];
