I want to switch from SetAsync to UpdateAsync (or better save system) please help?
I want to switch to UpdateAsync so players dont keep losing their data, but im not sure how to edit my code for it please help.

What you can do to prevent data loss is keep track of your data version history.
Have a variable in your playerData table called Version. Every time you update the player's data, add one to the version.
This way you'll know what version you're saving over so you don't overwrite a newer version.
First, make sure you have a table that contains the default data - data you want to save for the player when they're new to the game. Notice how there's a variable named version.
This is the version of the data you're saving. Since this is new data, the defaultData`s version variable is 0.
defaultData = {
--TODO: Insert default player data items such as strength, killed, etc.
Version = 0
}
Next, let's write a function called updateData()
Right now all it has are three variables:
- saveKey which is the player's datastore key.
- d which is where the player's in data is in game.
- playerData`, which is the player's data in a table.
function updateData()
local saveKey = prefix .. tostring(Player.UserId)
local d = Player.Data
--put the player's in game data in a table to save to the datatstore
local playerData = {
d.strength.Value,
d.strengthxp.Value,
d.defense.Value,
d.defensexp.Value,
d.ability.Value,
d.style.Value,
d.race.Value,
d.ate.Value,
d.killed.Value
d.Version.Value
}
--TODO: UpdateAsync() will go here, we'll talk about that in the next step
end
Now let's update the playerData to the datastore with UpdateAsync.
The code below will go where the TODO: comment in the previous step is, but I'm just writing it here because it's easier to read.
What the code is doing is checking if the data is valid (if the old data's version is the current version - 1), if it is, we'll update the data, if it's not, then the data isn't valid so we return nil and don't update
Data:UpdateAsync(saveKey, function(oldData)
--if the previous data doesn't exist, use the defaultData this is our first time saving the player's data, otherwise use the old data
local previousData = oldData or defaultData
--check to see if the data is valid
if playerData.Version == previousData.Version then
playerData.Version= playerData.Version+ 1
return playerData
else
return nil
end
end)
Tell me if you have any more questions
