Build Your First Roblox Game with Claude Code

Build me a pet simulator with 3 zones and a prestige system.

I want to make a tycoon game where players build and run a pizza restaurant.

Create a horror game — players explore a haunted mansion and try to escape a monster.

Make an obby with 50 stages, a timer, and a leaderboard for fastest completions.

Build a battle royale game for up to 20 players with a shrinking storm.

-- SERVER: Listen for client requests (in a Script inside ServerScriptService)
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local CollectRemote = ReplicatedStorage.Remotes.CollectResource

CollectRemote.OnServerEvent:Connect(function(player, nodeId)
    -- ALWAYS validate on the server — never trust the client
    if typeof(nodeId) ~= "string" then return end
    -- Process the collection authoritatively
    CollectionService:HandleCollect(player, nodeId)
end)

-- CLIENT: Fire the server when the player interacts (in a LocalScript)
local CollectRemote = game:GetService("ReplicatedStorage").Remotes.CollectResource
CollectRemote:FireServer(node.Name)

-- SERVER → CLIENT: Replicate the updated value back for display
CollectRemote:FireClient(player, newCoinTotal)

local DataStoreService = game:GetService("DataStoreService")
local store = DataStoreService:GetDataStore("PlayerData")

-- Reading data safely
local success, data = pcall(function()
    return store:GetAsync("Player_" .. player.UserId)
end)

if success and data then
    -- Apply saved data to the player session
    applyData(player, data)
else
    -- Fall back to defaults if load fails — never leave a player with nil data
    applyData(player, getDefaultData())
end

-- Writing data safely
local saveSuccess, saveErr = pcall(function()
    store:SetAsync("Player_" .. player.UserId, playerData)
end)

if not saveSuccess then
    warn("DataStore save failed for", player.Name, saveErr)
end
