At game start sometimes all dragdetectors work and sometimes they dont

Help and Feedback Scripting Support

What solutions have you tried so far? Look for solutions on the devforum, add a wait before loading the dragdetectors, debug, no errors,

The script handles all the dragdetectors,

this is the loading:

local CollectionService = game:GetService("CollectionService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TweenService = game:GetService("TweenService")
local Debris = game:GetService("Debris")

local function setup(instance)
	local primaryPart = instance
	if instance:IsA("Model") then
		primaryPart = instance.PrimaryPart
		if not primaryPart then
			warn(`{instance.Name} (Model) has no primarypart!`)
			return
		end
	elseif not instance:IsA("BasePart") then
		warn(`{instance.Name} is not a part or a model!`)
		return
	end

	primaryPart.CollisionGroup = "Dragging"

	local dragDetector = instance:FindFirstChildWhichIsA("DragDetector")
	if not dragDetector then
		local DD = script.DragDetector:Clone()
		DD.Parent = instance
		dragDetector = DD
	end

	dragDetector.ReferenceInstance = instance

	local PosAtt = Instance.new("Attachment")
	PosAtt.Parent = primaryPart

	local AlignPos = Instance.new("AlignPosition")
	AlignPos.Parent = primaryPart
	AlignPos.Attachment0 = PosAtt
	AlignPos.Enabled = false
	AlignPos.Responsiveness = 100

	local function GetLookAtt(plr)
		local char = plr.Character
		if not char then return end

		local hrp = char:FindFirstChild("HumanoidRootPart")
		if not hrp then return end

		local Att = hrp:FindFirstChild("LookAtt")
		if Att then
			return Att
		end
	end

	local highlight

	local function onHover(plr)
		if not highlight then
			highlight = script.Highlight:Clone()
			highlight.Parent = instance
			TweenService:Create(highlight, TweenInfo.new(.5), {OutlineTransparency = 0}):Play()

			instance:SetAttribute("CurrentHighlight", plr.UserId)
		end
	end

	local function onHoverEnd(plr)
		if highlight then
			TweenService:Create(highlight, TweenInfo.new(.5), {OutlineTransparency = 1}):Play()
			Debris:AddItem(highlight, .5)
			highlight = nil

			instance:SetAttribute("CurrentHighlight", nil)
		end
	end

	end)

		pcall(function()

		ReplicatedStorage.Events.Drag:FireClient(plr, true)

		if Att then
			local Y = viewFrame.LookVector.Y
			Att.CFrame = CFrame.new(Vector3.new(0, (Y * offset) + 1, -offset))

	end)

		end
		return false
	end)

	ReplicatedStorage.Events.Scroll.OnServerEvent:Connect(function(plr: Player, scroll: boolean)

			if scroll then
				offset = math.clamp(offset + .5, 5, 15)
			else
				offset = math.clamp(offset - .5, 5, 15)
			end
		end
	end)

	local touching = nil

	primaryPart.Touched:Connect(function(hit)
		if hit:IsA("BasePart") and instance:GetAttribute("CurrentDrag") then
			touching = hit
			print(instance.Name.." touched "..hit.Name)
		end
	end)

	primaryPart.TouchEnded:Connect(function(hit)
		if hit:IsA("BasePart") and instance:GetAttribute("CurrentDrag") then
			touching = nil
			print(instance.Name.." stopped touched "..hit.Name)
		end
	end)

	ReplicatedStorage.Events.Weld.OnServerEvent:Connect(function(plr: Player)

CollectionService:GetInstanceAddedSignal("Pickup"):Connect(function(instance)
	task.spawn(function()

	end)
end)

task.wait(5)

for _, instance in pairs(CollectionService:GetTagged("Pickup")) do
	task.spawn(function()
		setup(instance)
	end)
end

This looks good to me in principal. I copied the script, added a default dragdetector below it, scattered a bunch of parts and tagged them “Pickup”.
I did comment out all the replicatedstorage and highlight code.

But the objects dragged, and if I created and tagged a new part on the server, thje GetIstanceAddedSignal took care of hookup up its dragdetector.

In the case where it does not work, do you get any output to the console?
Can you give more detail aobut what doesn’t work and under what conditions?

Have tried moving task.wait(5) up a chunk… Even could put that top.
