i have this script

-- NPC Script

local questItems = {"Engine", "Battery", "Tire"}
local playerProgress = {}
local TextValue = 0

function updateBillboard(player, currentStep)
	local billboard = script.Parent:FindFirstChild("Billboard")
	if billboard then
		local billboardGui = billboard:FindFirstChild("BillboardGui")
		local label = billboardGui:FindFirstChild("TextLabel")
		if label then
			label.Text = TextValue .. "/3"
		end
	end
end

function onInteract(player)
	local progressData = playerProgress[player.UserId] or {}
	local currentStep = progressData.currentStep or 1

	if not progressData.completed then
		local requiredItem = questItems[currentStep]

		local hasRequiredItem = player.Backpack:FindFirstChild(requiredItem)
		if hasRequiredItem then
			hasRequiredItem:Destroy()
			progressData.currentStep = currentStep + 1
			TextValue = TextValue + 1

			if currentStep == #questItems then
				progressData.completed = true
				print("Quest completed! Items removed from your inventory.")
			else
				print("Good job! Now bring me a " .. questItems[currentStep + 1] .. ".")
			end

			updateBillboard(player, progressData.currentStep)
		else
			print("You don't have the required item.")
		end

		playerProgress[player.UserId] = progressData
	else
		print("You have already completed the quest.")
	end
end

local clickDetector = script.Parent:WaitForChild("ClickDetector")

clickDetector.MouseClick:Connect(function(player)
	onInteract(player)
end)

its almost done, the only problem is i want the player to equip the tool and click on the npc through the server script not just use the click detector and click on the npc to give him the tools. I will pay 350 robux to someone who can help me with the fix.

its almost done my only problem is that the player should equip each tool to give to the npc.

QuestTesting.rbxl (121.9 KB)

here is the updated server

#4

u can get the equipped tool by simply checking it inside the player’s character e.g

local hasRequiredItem = player.Character:FindFirstChild(requiredItem)
if hasRequiredItem then
 --ur code logic
#5

but then how will i make it so that the player can click the npc’s model with the tool equipped? thats just checking for the item.

#6

u can use the hasRequiredItem conditional statement inside the event

clickDetector.MouseClick:Connect(function(player) --event
   local progressData = playerProgress[player.UserId] or {}
	local currentStep = progressData.currentStep or 1

	if not progressData.completed then
		local requiredItem = questItems[currentStep]

		local hasRequiredItem = 
player.Backpack:FindFirstChild(requiredItem)
        --if player dont have the item, we cancel his request
        if not hasRequiredItem then return end
        --other code

I think the code u provided above should work, u just have to implement the tool equipped logic

#7

so adding this logic to my script should work?

clickDetector.MouseClick:Connect(function(player) --event
   local progressData = playerProgress[player.UserId] or {}
	local currentStep = progressData.currentStep or 1

	if not progressData.completed then
		local requiredItem = questItems[currentStep]

		local hasRequiredItem = 
player.Backpack:FindFirstChild(requiredItem)
        --if player dont have the item, we cancel his request
        if not hasRequiredItem then return end
        --other code

alright so i was able to simply add it in but the thing is, it works the same as before. What i have right now is when the player picks up the 3 needed tools the only way they can give it to the npc is by having all the tools unequipped and clicking the click detector 3 times. I want the player to be able to give the tools but the only way they can give it is by equipping the tool and clicking the npc.

Something like this?


local questItems = {"EngineTool", "BatteryTool", "TireTool"}  -- Updated with tool names
local playerProgress = {}
local TextValue = 0

function updateBillboard(player, currentStep)
    -- billboard update logic
end

function onToolInteract(player, tool)
    local progressData = playerProgress[player.UserId] or {}
    local currentStep = progressData.currentStep or 1

    if not progressData.completed and tool.Name == questItems[currentStep] then
        tool:Destroy()
        progressData.currentStep = currentStep + 1
        TextValue = TextValue + 1

        -- quest completion logic

        updateBillboard(player, progressData.currentStep)
        playerProgress[player.UserId] = progressData
    else
        print("You don't have the required tool or have already completed the quest.")
    end
end

local function setupToolListener(tool)
    tool.Equipped:Connect(function()
        local clickDetector = script.Parent:WaitForChild("ClickDetector")
        clickDetector.MouseClick:Connect(function(player)
            onToolInteract(player, tool)
        end)
    end)
end

game.Players.PlayerAdded:Connect(function(player)
    player.Backpack.ChildAdded:Connect(function(child)
        if child:IsA("Tool") then
            setupToolListener(child)
        end
    end)
end)

i made a minor mistake here. it should be

local hasRequiredItem = 
player.Character:FindFirstChild(requiredItem)
