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.
When variable is set on Location, it works only with locations created with createLocation.
All supported variable types:

• Namespace
• Object
• Group
• Team Member
• Task (FSM Task)
• Location (only scripted locations)
• Control (since Arma 3 v1.55.133553)
• Display (since Arma 3 v1.55.133553)

In Arma 3 it is possible to broadcast nil value

⚠

missionNamespace, uiNamespace, parsingNamespace and profileNamespace variable names could be any string, except for the reserved names, which are normally script command names. For example: missionNamespace setVariable ["west", 123]; will result in error:

Error in expression <missionNamespace setVariable ["west", 123];>
   Error position: <setVariable ["west", 123];>
   Error Reserved variable in expression  

as west is a script command. Other varspaces do not have such limitation. You can always check for all available script commands by running utility number 5

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.

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

• Boolean - when true, the variable broadcast is global and persistent
• Number - the variable is set only on the client of given owner (clientOwner) id, or if id is negative, the variable is set on every client except the given one
• Array of Numbers - array of owner (clientOwner) ids

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)).
