Datastore & Purchase System is where progress lives: set what a new player starts with, and every pack saves into that same save.

What you get

  • The default data in the plugin: groups and keys with their types

    You describe the save

    Groups and keys, typed. No code.

  • The preview of exactly what a new player gets

    A new player's save

    See it whole before you press Play.

  • Datastore & Purchase System in the plugin: auto-save, save versions and Wipe Studio Data

    Safe testing

    Studio never touches your live saves.

  • A new session after leaving: the saved Cash and the pets loaded back

    Saved across sessions

    Leave, come back, and everything is still there.

In 3 steps

  1. Install from the plugin card

    Open the free plugin, go to My packs and press Install on Datastore & Purchase System. What it needs installs with it.

  2. Tell your AI

    Claude Code, Codex or any agent connected to Studio sets it up from a plain request: "Give new players 5 Gems." Or change it by hand in the plugin.

  3. Press Play

    It works straight away. No script editing.

Your AI adds a stat to the save data, and the Player shows it.

FAQ

Do the other packs need it?

Every pack that saves needs it, so the plugin installs it with them. It is free for everyone.

Does testing in Studio touch live saves?

No. Studio saves to its own store, so a playtest never changes a real player's data.
