Here is also a pic of the leaderboard setup i test today. Maybe it is easier to see how the selection works there.
Edit:
Turns out to do the Leadboard this way is almost impossible. I should have calculate before testing. This way i end up with almost 100k data in a single game mode struct. It´s just not doable. So i need to find a better way to store the leaderboards. Sounds good and easy to handle on paper but it is definitely not the way to do this.
Guess will need to go back to try the DataAssets again even if i hade problems with using them the time i tried (not the usage but compiling almost crushed the project a few times).
But it seems like this is the way to go for something like this.
