Description

Description:
Selects an element from an array, config entry from Config or substring from a string (since ["Arma 3","Arma3",127,126674,"Development"]).
Groups:
Uncategorised

Syntax 1

Syntax:
array select index
Parameters:
array : Array
index: Number - Index 0 denotes the first element, 1 the second, etc. If index has decimal places it gets rounded down for fractions less than or equal .5, otherwise it gets rounded up.
Return Value:
Anything

Syntax 2

Syntax:
array select boolean
Parameters:
array : Array
boolean: Boolean - true => 1, false => 0
Return Value:
Anything

Syntax 3

Syntax:
config select index
Parameters:
config : Config
index: Number - Index 0 denotes the first element, 1 the second, etc. If index has decimal places it gets rounded down for fractions less than or equal .5, otherwise it gets rounded up.
Return Value:
Config

Syntax 4

Syntax:
string select [start, length]
Parameters:
string: String
[start, length]: Array
start: Number - String position to start selection from. 0 denotes the first character of the string, 1 the second, etc. If passed number has decimal places it gets rounded down for fractions less than or equal .5, otherwise it gets rounded up.
length (optional): Number - Number of the string characters to select. If "length" is omitted, selection will be made from "start" to the end of the string.
Return Value:
String

Examples

Example 1:
[1,2,3,4] select 2; //result is 3 position player select 2; //result is Z coordinate of player position
Example 2:
["", currentWeapon player] select alive player; //if dead "" is selected
Example 3:
(configFile >> "cfgVehicles" >> typeOf vehicle player >> "Turrets") select 0 >> "gunnerAction";
Example 4:
hint str ("japa is the man!" select [8]); //the man! hint str ("japa is the man!" select [0,7]); //japa is

When combined with the count command, this can be used to read all entries out of a config; even when you don't know exactly how many entries there will be. See the notes under count for more info.

Rounding of fractions with select is not the same as when you use round command: _roundThis = 0.5; hint str ([0,1] select _roundThis); //0 hint str round _roundThis; //1

In ArmA3 ver 1.18, Boolean type supported. Which true defaulted as 1 and false as 0. [0,1] select (56 > 40) // 1 [0,1,2] select ((!isNil "v") && false) // 0
