Description

Description:
Set variable to given value in the variable space of given element. Can be used to broadcast variables over the network. To remove a variable, set it to nil (see Example 5).
missionNamespace, uiNamespace, parsingNamespace and profileNamespace variable names can be any string but reserved names such as script commands. 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 scripting command. Other varspaces do not have such limitation. See also all available script commands.
Multiplayer:
The variable space of the object is local to each client and by default changes are not broadcast.
Groups:
MultiplayerVariables

Example 3:
missionNamespace setVariable ["TAG_myName", "Brian"]; hint TAG_myName; // hints "Brian"
Example 4:
Get the current value of a variable or, if it is undefined, define it and then get the value: private _var = missionNamespace getVariable "VarName"; if (isNil "_var") then { _var = 123; missionNamespace setVariable ["VarName", _var]; }; // _var now contains the current value of the missionNamespace variable varName
Example 5:
Remove TAG_myPublicVariable from _myTruck (globally): _myTruck setVariable ["TAG_myPublicVariable", nil, true];
