Cannot store Array in DataStore?
Ok so i have been working on this script, trying to make it save the children in the Weaps model and then load it into the model when the player enters, everything looks like it would work but when i test it the output says "Cannot store Array in DataStore" or somthing? Can somone tell me what that means and how to fix it?
local datastore = game:GetService("DataStoreService"):GetDataStore("RobloxBackPack")
-------------------------------------------------------------------------
local wm = Instance.new("Model")
wm.Name = "Weaps"
function give(weap, player)
for _, w in ipairs(game.StarterPack:GetChildren()) do
if w.Name == weap.Name then return end
end
weap:clone().Parent = player.Weaps
end
game.Players.ChildAdded:connect(function(p)
wm:clone().Parent = p
wait()
p.Character.ChildAdded:connect(function(wep)
if wep.className == "Tool" then
give(wep, p)
end
end)
p.Changed:connect(function(pr)
if pr == "Character" then
for _, w in ipairs(p.Weaps:GetChildren()) do
w:clone().Parent = p.Backpack
end
p.Character.ChildAdded:connect(function(wep)
if wep.className == "Tool" then
give(wep, p)
end
end)
end
end)
p.Backpack.ChildAdded:connect(function(h)
if h.className == "HopperBin" then
give(h, p)
end
end)
end)
game.Players.PlayerAdded:connect(function(player) --Datastore stuff
local key = "user-" .. player.userId
local storeditems = datastore:GetAsync(key)
if storeditems then
local Special = storeditems[1]
Special.Parent = player.Weaps
else
local get = player.Weaps:GetChildren()
for i, v in pairs(get)do
local Potato = v:clone()
local items = {Potato}
datastore:SetAsync(key, items)
end
end
end)
--Says it cannot save a data array?
game.Players.PlayerRemoving:connect(function(player) -- more datastore stuff
local get = player.Weaps:GetChildren()
for i, v in pairs(get)do
local Potato = v:clone()
local items = {Potato}
local key = "user-" .. player.userId
datastore:SetAsync(key, items)
end
end)

You cannot store objects in the data store, you will have to save a value which represents the item.
Secondly you are also overwriting the data saved as the SetAsync. "Sets the value of the key. This overwrites any existing data stored in the key. "
To save the data you will need either a key value table or an array. More info can be found here.
As you are loading the data as an array e.g.
local Special = storeditems[1]
Then you will need to save the data as an array:-
game.Players.PlayerRemoving:connect(function(player) -- more datastore stuff
local key = "user-" .. player.userId
local items = {} -- our array of data
for i, v in pairs(player.Weaps:GetChildren()) do
-- e.g tool name is sword so we save a 1 ect
local item = [some method to turn the object to a value e.g. string or int]
table.insert(items, item) -- adds this value to out items list
end
datastore:SetAsync(key, items) -- once all items have been added save the array list
end)
When loading the data simply convert the numbers back into the tools ect which the player had.
Hope this helps.
