This command allows you to check for the presence of an addon.
 isClass (configFile >> "cfgVehicles" >> "MyCustomCar")
will return [true](../commands/true.md) if the addon "MyCustomCar" is installed, and [false](../commands/false.md) if it is not installed.

*You will have to know under which class the addon is categorized (in this case "cfgVehicles") to be able to use the right config path.*

(Arma 3 ver 1.14) According to BI Dev Karel Mořický, [BIS_fnc_getCfgIsClass](../functions/BIS_fnc_getCfgIsClass.md) provides a comfortable workaround with custom config under description.ext compared with [isClass](../commands/isClass.md).
(But as a function created specifically for A3 campaign, it is in no way intended as a replacement for [isClass](../commands/isClass.md).
So it is not suggested to use it for [configFile](../commands/configFile.md) classes. But [isClass](../commands/isClass.md) instead.)
E.g.

```sqf
["Something1", "Something2", "Something3"] call BIS_fnc_getCfgIsClass; // same as isClass (missionConfigFile >> "Something1" >> "Something2" >> "Something3")
```
