- UE Plugin to handle arrays operations (sort, filter, match, range, clamp, random, average, min, max, normalize)
- Use custom predicate function to sort or filter arrays (Int, Float, Byte, Integer64, String, Name, Vector, Object, Actor, Generic)
- This is a blueprint library plugin
- It exposes 60+ functions to handle arrays by value or by reference
- Can be used in any blueprint

Note v2: In order to sort by predicate you must create a functions by dragging the PredicateFunction pin and select create event, then create or select a matching function in the list
Note v1.1 and minor: In order to sort by predicate you must implement the ArrayComparator Interface and pass the object implementing this interface as input of the function (Context), the appropriate compare method will be called to perform the sort
