You can write your topic however you want, but you need to answer these questions:
- What do you want to achieve? Keep it simple and clear!
I’m trying to give player’s clothing when they join and that clothing to save when they leave the game and load the same clothing when thet join back.
- What is the issue? Include screenshots / videos if possible!
So I created a diccionary to store the player’s Shirt and Pants templates. The thing is that when a player with saved data tries to rejoin the game it will give this error on the function that gives player’s clothing:
“ServerScriptService.ClothingSystem:40: attempt to index nil with ‘ShirtTemplate’”
I thought it would be that probably I didn’t saved the value correctly and it was a nil, however when I tried printing it, it actually printed the player’s clothing so that wasn’t the problem.
- What solutions have you tried so far? Did you look for solutions on the Developer Hub?
As it’s usual for me, I’m the only one who got this problem (or at least I think so.) because I just learnt what is Json and how to “use it” yesterday.
This is the full code:
local Module = require(game.ReplicatedStorage.Modules.Functions)
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("PlayerClothingDatastore")
local HttpService = game:GetService("HttpService")
function addClothing(player, character, ShirtId, PantsId)
repeat wait() until player:HasAppearanceLoaded()
local Shirt
local Pants
if not character:FindFirstChildOfClass("Shirt") then
Shirt = Instance.new("Shirt")
Shirt.Parent = character
elseif character:FindFirstChildOfClass("Shirt") then
Shirt = character:FindFirstChildOfClass("Shirt")
end
if not character:FindFirstChildOfClass("Pants") then
Pants = Instance.new("Pants")
Pants.Parent = character
elseif character:FindFirstChildOfClass("Pants") then
Pants = character:FindFirstChildOfClass("Pants")
end
local success, model = pcall(function()
return game:GetService("InsertService"):LoadAsset(ShirtId)
end)
if success then
model.Parent = workspace.Clothing
end
local success2, model2 = pcall(function()
return game:GetService("InsertService"):LoadAsset(PantsId)
end)
if success2 then
model2.Parent = workspace.Clothing
end
wait()
if Shirt then Shirt.ShirtTemplate = model.Shirt.ShirtTemplate end
if Pants then Pants.PantsTemplate = model2.Pants.PantsTemplate end
end
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(Character)
local success, data = pcall(function()
return DataStore:GetAsync(player.UserId)
end)
if success and Character:FindFirstChild("Pants") and Character:FindFirstChild("Shirt") then
print("Successfully obtained data for player",player)
if data then
print("Data was found!")
local Decoded_Json = HttpService:JSONDecode(data)
local ShirtID = tostring(string.sub(Decoded_Json["Shirt"], string.find(Decoded_Json["Shirt"],"=")+1, string.len(Decoded_Json["Shirt"])))
local PantsID = tostring(string.sub(Decoded_Json["Pants"], string.find(Decoded_Json["Pants"],"=")+1, string.len(Decoded_Json["Pants"])))
addClothing(player, Character, ShirtID, PantsID)
else
wait()
print("Data wasn't found")
addClothing(player, Character, Module.GetShirt(), Module.GetPants())
wait()
print("New Data Saved")
local Table = {
["Pants"] = player.Character:WaitForChild("Pants").PantsTemplate,
["Shirt"] = player.Character:WaitForChild("Pants").PantsTemplate
}
local NewData = HttpService:JSONEncode(Table)
local success, err = pcall(function()
DataStore:SetAsync(player.UserId, NewData)
end)
if success then
print("Data saved for player",player)
else
print("Data did not save for player",player,err)
end
end
else
print("Couldn't load data for player",player)
player:Kick("Rejoin please")
end
end)
end)
game.Players.PlayerRemoving:Connect(function(player)
local Table = {
["Pants"] = player.Character:WaitForChild("Pants").PantsTemplate,
["Shirt"] = player.Character:WaitForChild("Pants").PantsTemplate
}
local data = HttpService:JSONEncode(Table)
local success, err = pcall(function()
DataStore:SetAsync(player.UserId, data)
end)
if success then
print("Data saved for player", player)
else
print("Data couldn't save for player", player, err)
end
end)
game:BindToClose(function()
for i, player in pairs(game.Players:GetPlayers()) do
local Table = {
["Pants"] = player.Character:WaitForChild("Pants").PantsTemplate,
["Shirt"] = player.Character:WaitForChild("Pants").PantsTemplate
}
local data = HttpService:JSONEncode(Table)
local success, err = pcall(function()
DataStore:SetAsync(player.UserId, data)
end)
if success then
print("Data saved for player",player)
else
print("Data couldn't save for player",player,err)
end
end
end)
Hope you can help me, I’m really having struggles understand Json and HttpService in general.
