    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This is a blueprint library plugin

It exposes 60 functions to handle arrays by value or by reference

Can be used in any blueprint

Documentation can be found here :

If you wish to update the current array, use functions with "ref" for performance

If you wish to keep the current array and receive another array as output, use standard function without "ref" (a copy of the array will be made)

To use the sort or filter by predicate, implement ArrayComparator or ArrayFilter interface in a blueprint and pass it as Context

If you find a bug, please contact me, I will fix it

If you want a new feature to handle arrays, contact me, I will implement it eventually
