ROBLOX String Value Datastore?

Data store can save all values that can be interpreted by another language. This includes strings, bools, numbers, and tables. Let's try going over this step by step:

Getting data store service

local DataStoreService = game:GetService'DataStoreService'

Creating a new data store

So, data store gives us the neat option to basically create a table we can save data to. We can create such a table with using the "GetDataStore" method on the data store service, like so:

local DataStoreService = game:GetService'DataStoreService'
local MyData = DataStoreService:GetDataStore'Testing'

If "Testing" already exists, it will retrieve all data from that table. If not, it will create a new one that we can configure.

Saving data

We can save data to this newly created table, using "SetAsync" and "UpdateAsync". Let's try an example of SetAsync:

-- Data stuff
local DataStoreService = game:GetService'DataStoreService'
local MyData = DataStoreService:GetDataStore'Testing'

-- New data
MyData:SetAsync("Key1" , "Hello world")

In the example above, we set "Key1" to the value of "Hello world". In Lua understanding, we can basically say it looks like this:

local DataStoreService = {
    ['MyData'] = {
        ['Key1'] = 'Hello world'
    }
}

Now, don't take this literally, but this can be a very clear way to look at it and understand it.

Getting data

Let's test our example by printing the data we saved with "print" and "GetAsync"

-- Data stuff
local DataStoreService = game:GetService'DataStoreService'
local MyData = DataStoreService:GetDataStore'Testing'

-- New data
MyData:SetAsync("Key1" , "Hello world")

-- Print results
print(MyData:GetAsync("Key1"))  -- > "Hello world"
