Description
- Description:
- Sets a variable to the innermost scope as demonstrated in Example 3. See also param and params.
- Groups:
- Variables
Syntax 1
Syntax 2
- Syntax:
- private variableNameList
- Parameters:
- variableNameList: Array of Strings, e.g ["_target", "_damage"]
- Return Value:
- Nothing
Syntax 3
- Syntax:
- private _identifier = value Template:Since
- Parameters:
- _identifier: underscored variable name, for example _myVar
- value: Anything: value to assign to the variable
- Return Value:
- Nothing
Examples
- Example 1:
private _varname = "this is my new variable"; // since Arma 3 v1.53 only // identical, but less performant private "_varname"; _varname = "this is my new variable";- Example 2:
private ["_varname1", "_varname2"]; _varname1 = "variable 1"; _varname2 = "variable 2";- Example 3:
_lol = 123; call { hint str [_lol] }; // [123] _lol = 123; call { private "_lol"; hint str [_lol] }; // [any]- Example 4:
_myvar = 123; systemChat str [_myvar]; // [123] call { systemChat str [_myvar]; // [123] private "_myvar"; systemChat str [_myvar]; // [any] _myvar = 345; systemChat str [_myvar]; // [345] }; systemChat str [_myvar]; // [123]

- The higher scope is also the script from which the function has been called.
in script2.sqf:_a = 2;in script1.sqf:_a = 1; call compile preprocessFileLineNumbers "script2.sqf"; hint format ["%1", _a];
Game will display 2.
Insertingprivate "_a"in the function prevents the change and so number 1 will be displayed on the screen. - Posted on February 25, 2015 - 17:06 (UTC)

- Recursive loops require the use of private. Without it, your variables will be overwritten.

This command is similar to javascript's let keyword.
EDIT: in the way that it scopes the variable to the innermost scope. Otherwise, let and private can behave differently - Lou Montana (talk)
