Question 1

How to prevent item duping in Roblox games?

Accepted Answer

ProfileStore uses session locking to ensure only one server modifies player data at a time, preventing conflicts that cause duplication. It's specifically designed for trading systems in multiplayer games.

Question 2

ProfileStore vs Roblox DataStoreService: which is better for player data?

Accepted Answer

ProfileStore is a wrapper that adds auto-saving and session locking, making it superior for preventing dupes and simplifying management. DataStoreService is more flexible but requires manual handling of conflicts and caching.

Question 3

How to set up auto-saving with ProfileStore?

Accepted Answer

Initialize a ProfileStore instance and start sessions for players using :StartSessionAsync(). Data is automatically saved periodically or when sessions end, as detailed in the documentation.

Question 4

What happens if a server crashes during a ProfileStore session?

Accepted Answer

ProfileStore gracefully handles conflicts, allowing other servers to take over sessions without data loss. However, recovery specifics depend on implementation; check the wiki for best practices.

Question 5

Can ProfileStore handle leaderboard data?

Accepted Answer

No, ProfileStore is optimized for player data and not suitable for leaderboards or global state, as it prioritizes reliability and simplicity for individual profiles over concurrent access.

Question 6

How to migrate existing player data to ProfileStore?

Accepted Answer

Write a migration script to load data from old storage into ProfileStore profiles, ensuring the structure matches. This may require manual adjustments based on your game's data schema.
