how to save shop items bought?

Quick and easy question, i have a shop with trails, and pets, how would i save the trails, and pets bought, so no player has to restart on buying everything again?

To start, you need to learn DataStore, or be lazy and get spoonfed by pre-made code.

There is a good & simple method to save it, here's an a practical explanation:

Before starting,

• Store all of the tools / items in a folder where a script can access.

When the player leaves

• Check if they have any tools in their backpack,

  • If they do have tools / items then, (if statement)

    • Store the tools' / items' name that are in their backpack into a datastore. (Table)

  • If they don't have tools / items then, (if statement)

    • Store nil or nothing in the datastore. (nil)

When the player joins back

• Check if they have any tools / items saved in the datastore,

  • If they do have tools / items in the data store then: (if statement)

    • Look into the folder where all the tools / items are stored, (pairs())

      • Restore the tools / items back into their backpack. (:Clone())

  • If they don't have tools / items in the data store then: (if statement)

    • Don't do anything.
