# Objects with "world context"

If you create a class off of a base UObject, it isn't guaranteed to have a "world context". For this reason, Unreal will hide away any methods that require a "world context object". This includes a lot of common, useful helpers, like `GetAllActorsOfClass`.

To help with this, we have added a `M2_ObjectWithWorldContext` helper - classes extending this will display the methods that require a world context object. If you create these objects with a suitable outer, that has the world context, then these methods will work.
