Unreal Engine Tutorial Blueprint 12: Arrays, Lists and Maps

This video teaches about using list-based variables in Unreal Blueprint Scripting. It focuses on Arrays and Maps (which is the Unreal name for what is often called an associative array, or a dictionary.) It mentions, but does not explore sets, which is the unordered list type. It shows various ways of defining and using these data structures, and some of the most common nodes associated with them. It was created using UE4.26 but the implementation has not changed from earlier versions of Unreal.
