Persistent Player Statistics

Many experiences use player stats to track player experience data over time. Statistics like high score, total games won, total play time and collected items give players a sense of progression and are all great ways to encourage players to return to your experience.

Verse Persistence is a powerful tool that allows you to add persistable data to your Verse scripts. Persistable data is saved on a per-player, per-island basis, and stays the same between gameplay sessions. Persistable data will allow you to track player progress between play sessions and will open up a variety of unique and interesting play experiences previously unavailable in UEFN.

This tutorial will show you how to create a custom table of player stats using Verse and set them up to be persistent across multiple plays of your experience.
