Object.FindObjectOfType
static function FindObjectOfType(type: Type): Object;
static Object FindObjectOfType(Type type);
static def FindObjectOfType(type as Type) as Object
Description

Returns the first active loaded object of Type type.

Please note that this function is very slow. It is not recommended to use this function every frame. In most cases you can use the singleton pattern instead.
