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.
- Groups:

Syntax
- Syntax:
- condition configClasses config
- Parameters:
- condition: String
- config: Config
- Return Value:
- Array - array of Configs
Examples
- Example 1:
- collect all CfgVehicles configs:
- 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':

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

- this will get a list of ALL locations on the currently loaded world
