DataStores for Inventory

Help and Feedback Scripting Support
#1

I’ve created an inventory script that allows the player to pick up and drop items, these items are stored in IntValues within a folder inside the player. How would I go about saving and loading each of those values?

Create a table and add those items in the table and save the table in DATASTORE.

I’ve answered to something similar there and you shouldn’t have to change the script too much

I just decided to write up a little script for you to achieve this.

#5

How would I go about saving both the name of the value and the value of it?

#6

Good point, that makes things a little trickier (storing a dictionary of tables) but here:

#7

I’m getting this error for just under game:BindToClose(function())

ServerScriptService.Script:40: invalid argument #1 to ‘pairs’ (table expected, got Instance)

#8

Uh, that’s not the script I posted.

#9

I changed a few things to suit the Inventory I have, it’s inside a folder called Inventory inside of player.

I had to remove the “local player = players.LocalPlayer or players.PlayerAdded:Wait()” because it was saying “Player.PlayerAdded” isn’t apart of player.

#10

Oh, that was just a mistake on my part, should have been players.PlayerAdded instead.

Add the bits again to this script & repost it. The error was in relation to something you had added, so I’ll likely need to see how everything is organised on your end.

#11

So in this one I’ve just changed storage to where my inventory is.

#12

Can I see how everything is organised your end?

#13

Yeah of-course!

Have a wee look, sorry for all the bother.

#14

Oh never mind, I see the change at the top. I’ll get to it shortly.

#15

Just noticed everything had “player.PlayerRemoving” too it should have been “players.PlayerRemoving” I’ve fixed that too.

Should Weight be inside inventory?

#17

No weight can stay inside PlayerData. It’s not saving/loading for me any ideas why?

Okay, so the DataStore is working, now you just need to make it so that the inventory stuff is correctly given to the user.

I’ve sent you a message containing a modified .rbxl file.
