Description

Description:

Returns an array of config entries which meet criteria in condition code. Command iterates through all available config sub classes of the given config class. Current looked at config is stored in _x variable (similar to alternative count command implementation). Condition has to return true in order for the looked at config to be added to the resulting array. Slightly faster than configProperties, but doesn't account for config properties or inherited entries.

⚠

The condition code passed to configClasses should only be used for simple filter expressions and nothing more
Do not use "isClass _x" in the condition. The engine does this check already
Arma 3 v2.02 brought specific engine optimisations for the following conditions:
- "true"
- "getNumber (_x >> 'scope') > 0"

Syntax

Syntax:: condition configClasses config
Parameters:: condition: String
: config: Config
Return Value:: Array - array of Configs

2.22

Alternative Syntax

Syntax:: configClasses [config, depth, includeInherited, allSubclasses, classNames]
Parameters:: config: Config - target config
: depth: Number - how many levels of subclasses to go deep
: includeInherited: Boolean - true to look through inherited classes
: allSubclasses: Boolean - true to return all subclasses, false - to return only the last tier.
: classnames: (Optional) Boolean - when true class names Strings are retuned, when false - Configs are returned. Default: false
Return Value:: Array - array of Configs or Strings, which represent class names.

Examples

Example 1:: collect all CfgVehicles configs:
_configs = "true" configClasses (configFile >> "CfgVehicles");
Example 2:: Return all classes that can transport 10 and more soldiers:
_transporters = "getNumber (_x >> 'transportSoldier') >= 10" configClasses (configFile >> "CfgVehicles");
Example 3:: Return all classes that inherit from 'RscText':
hint str ("inheritsFrom _x == (configFile >> 'RscText')" configClasses configFile);
Example 4:: Return children:
configClasses [configFile >> "CfgGroups", 0, true, true, true] //Returns ["West","East","Indep","Empty"]

: A fantastic way to filter stuff. eg:
// create an array of west vehicles and spawn then in front of the player in rows of 5 private ["_cfgArray", "_xPos", "_yPos", "_veh"]; _cfgArray = "( (getNumber (_x >> 'scope') >= 2) && { getNumber (_x >> 'side') == 1 && { getText (_x >> 'vehicleClass') in ['Armored', 'Car', 'Air'] } } )" configClasses (configFile >> "CfgVehicles"); _xPos = 0; _yPos = 0; { _yPos = _yPos + 20; _veh = createVehicle [(configName _x), player modelToWorld [_xPos, _yPos, 0], [], 0, "NONE"]; if (_yPos >= 100) then { _yPos = 0; _xPos = _xPos + 20; }; } forEach _cfgArray;

: configClasses does not account for inherited subclasses, use configProperties with isClass filter instead
configProperties [_config, "isClass _x", true];

: this will get a list of ALL locations on the currently loaded world
( "true" configClasses (configFile >> "CfgWorlds" >> worldName >> "names" ) ) apply { // change each config entry into a location nearestLocation [ getArray ( _x >> "position" ), getText ( _x >> "type" ) ] };
