Description

Description:
Set variable to given value in the variable space of given element.
To remove a variable, set it to nil (e.g. player setVariable ["varname", nil];).
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 setVariable will not work.
All supported variable types:
Arma 3
In Arma 3 it is possible to broadcast nil value
Multiplayer:
The variable space of the object is local to each client and by default changes are not broadcast.
Since Arma 2: If the public parameter for supported types is true, the value will be synchronized also for a JIP player.
Groups:
Uncategorised

Syntax

Syntax:
varspace setVariable [name, value]
Parameters:
varspace: Namespace, Object, Group, Team_Member, Task, Location, Control, Display - variable space in which variable can be set
[name, value]: Array
name: String - variable name
value: Anything - variable value
Return Value:
Nothing

Alternative Syntax

Syntax:
varspace setVariable [name, value, public]
Parameters:
varspace: missionNamespace, Object or Group - variable space in which variable can be set
[name, value, public]: Array
name: String - variable name
value: Anything - variable value (if public is true, check publicVariable for what types are supported for broadcast)
public: Boolean, Number or Array of Numbers
Return Value:
Nothing

Examples

Example 1:
_myTruck setVariable ["myPublicVariable", 123, true];
Example 2:
_myTruck setVariable ["myLocalVariable", ["321", _var], false];
Example 3:
missionNamespace setVariable ["myName", "KK"]; hint myName; //KK
Example 4:
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

This command does not work with CfgAmmo or CfgNonAIVehicles objects, like bullets, mines or butterflies (probably because they are local objects Killzone Kid (talk) 11:25, 9 July 2017 (CEST)).
