I have a ‘Door BP’ in which I reference 4 keys. Each key is a separate BP used to unlock instances/copies of the ‘Door BP’. For example, ‘BP Door Key Front’ is used to unlock the instance of ‘Door BP’ named ‘Front Door BP’. I have used ‘All Actors Of Class’ to reference each Key BP inside my ‘Door BP’ (see pic). This works but have a feeling using an array might be more economical, but have no experience using arrays. If anyone knows what type of array I would use and how I use it, that’d be great. Thanks.
