How do merge 2 distinct array of object, and then sort it?

[artest113]

Hello everyone,

As per title, how do I merge 2 different objects of array into one, and then sort or make a new array out of it with sorted attribute? It goes like this:

ArrayA:
Display Name: Amy , Score: 40
Display Name: James, Score: 50

ArrayB:
Display Name: Alex, Score: 60
Display Name: Lex, Score: 70

Expected New Array
ArrayC:
Display Name: Amy , Score: 40
Display Name: James, Score: 50
Display Name: Alex, Score: 60
Display Name: Lex, Score: 70

ArrayA and ArrayB objects are made up of different character class.

Blueprint or C++?

Without an idea of your knowledge of blueprint, guess a generic way could be:

1. One of the characters or a third class is needed to have a reference to all actors with the data to merge.
2. Iterate the references to append each to a new array or an existing one.
3. swap the indexes using your favorite sorting algorithm.

And of course do all this inside a function.

If a third class is used there is also the option to get the array using an interface to avoid the include of the character class.

Hope it helps. Let me know if you need anything specific.
