- MultiplayerVariables
Syntax
- Syntax:
- Syntax needed
- Parameters:
- varspace: Namespace, Object, Display, Control, Group, Location, Task, Team Member, Display, Control
- name: String - variable name that was defined in setVariable
- Return Value:
- Return value needed
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 - Posted on August 31, 2017 - 03:29 (UTC)

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