How do I sum all instances matching another instance?

Hi!

I have a family with many objects with four family instance variables. The first one (string) is the type of this object (for example "Enemy1", "Enemy2", etc.) and the other ones are values (for example "Health","Attack", etc.).

What I want is to sum all these number instance variables for each type of object (for example, health of all Enemy1s toghether, and then attack of all Enemy2s toghether, etc.).

For each lets you use a family and not just objects so just use that.

Yes, I know. But as every object had many instances, I had to use an Array.

Anyway, now it's solved, thank you Maukka
