Handle repeated interactions and cleanup

local nextAllowed = 0
if os.clock() < nextAllowed then return end
nextAllowed = os.clock() + 1

A one-second server-side cooldown denies repeated work until the next permitted time.

New syntax: cooldowns, cleanup, prompt-validation

Main guided reference implementation; use the hierarchy’s stated Script or ModuleScript type.

local Players = game:GetService("Players")
local lamp = game:GetService("Workspace"):WaitForChild("WorkshopLamp")
local prompt = lamp:WaitForChild("ProximityPrompt")
local nextAllowed = {}
local lit = false
local connection = prompt.Triggered:Connect(function(player)
    local character = player.Character
    local root = character and character:FindFirstChild("HumanoidRootPart")
    local humanoid = character and character:FindFirstChildOfClass("Humanoid")
    if not root or not root:IsA("BasePart") or not humanoid or humanoid.Health <= 0 then return end
    if (root.Position - lamp.Position).Magnitude > 10 then return end
    local now = os.clock()
    if now < (nextAllowed[player.UserId] or 0) then return end
    nextAllowed[player.UserId] = now + 1
    lit = not lit
    lamp.Color = lit and Color3.fromRGB(234,120,40) or Color3.fromRGB(100,100,100)
    print(lit and "Lamp on" or "Lamp off")
end)
local removing = Players.PlayerRemoving:Connect(function(player) nextAllowed[player.UserId] = nil end)
lamp.Destroying:Connect(function() connection:Disconnect(); removing:Disconnect(); table.clear(nextAllowed) end)

A missing HumanoidRootPart during spawning should reject safely, not throw.

Distance is measured from the server character root to this Part center; choose tolerances deliberately in a real game.

This is a bounded learning lab. It has not been executed in an approved Roblox Studio environment by this website.

A checked checklist records your own review, not automated project competence or a community verification.

A cooldown stores when the next interaction is allowed. Use a monotonic session clock such as os.clock for elapsed-time comparisons, not a local player claim.

A prompt is still a client-triggered surface. For this lamp, check that the server sees a live character close to the lamp. Prompt UI settings alone are not a general security boundary.

Store the event connection and disconnect it when the lamp is destroyed. Clear temporary per-player state on PlayerRemoving.
