Sending a cloned object to the server through a remote event?

Help and Feedback Scripting Support
#1

so I just created a custom copy tool which I am happy about because I dont have to use one from the toolbox pre-made.
but I ran into the issue of replicating copied parts to the workspace. if I try this:

local sendobject = selected
		local sendpos = selected.Position
		script.Parent.ChangeEvent:FireServer(sendobject,sendpos)

selected is the part Im trying to send over. but the part “selected” is nil. I also tried cloning selected but it also comes up nil. here is the entire copy tool:

--values
local debounce = false
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local tool = script.Parent
local box = Instance.new("SelectionBox")

local selected
local orig	
local dragger
--

function buttondown(mouse)
	local target = mouse.Target
	if target and target:IsA("BasePart") then
		if not debounce then
			debounce = true
			
			orig = target
			selected = orig:Clone()
			selected.Parent = game.Workspace
			selected.Position = orig.Position + Vector3.new(0,0.4,0)
			
			dragger = Instance.new("Dragger")
			pcall(function() dragger:MouseDown(selected, Vector3.new(0, 0, 0), {selected}) end)
		box.Adornee = selected
		wait(0.5)-- wait before going again
		debounce = false
		end
	end
end



function buttonup(mouse)
	if dragger then
		local sendobject = selected
		local sendpos = selected.Position
		script.Parent.ChangeEvent:FireServer(sendobject,sendpos)
		orig = nil
		pcall(function() dragger:MouseUp() end)
		selected = nil
		box.Adornee = nil
		dragger = nil
	end
end



function mousemove(mouse)
	if dragger then
		pcall(function() dragger:MouseMove(mouse.UnitRay) end)
	end
end




function keymover(key)
	if dragger then
		key = key:lower()
		if key == 'r' then
			dragger:AxisRotate(Enum.Axis.Y)
		elseif key == 't' then
			dragger:AxisRotate(Enum.Axis.Z)
		end
	end
end




function onEquippedLocal(mouse)
	box.Color = BrickColor.new("Lime green")
	box.Parent = plr.PlayerGui

	mouse.Button1Down:connect(function() buttondown(mouse) end)
	mouse.Button1Up:connect(function() buttonup(mouse) end)
	mouse.Move:connect(function() mousemove(mouse) end)
	mouse.KeyDown:connect(keymover)
end






function onUnequippedLocal(mouse)
	if dragger then
		orig = nil
		pcall(function() dragger:MouseUp() end)
		selected = nil
		box.Adornee = nil
		dragger = nil
	end
end


tool.Equipped:connect(onEquippedLocal)
tool.Unequipped:connect(onUnequippedLocal)

is there a way for me to get the cloned part to not be ignored by the server?

Err, not really. “Sending” an object via a remote event really just passes a reference of that object, rather than the object itself.

I would recommend you read though this article

but the object Im trying to pass to the server is nil

You could send the properties of the part through the remote event, and make the server create a new part with all the properties

I might have to do it that way as any attempt I make at sending it through a remote event as an object ends up nil.

It seems like you’re cloning parts on the client, a part that exists only on the client can’t be referenced by the server

As a solution you can pass the object you’re cloning to the server and clone it from the server itself (where the original part is presumably global)

Apparently you cannot pass parts, despite what the wiki says… I just tested it in studio.

The method provided on the wiki basically shows a “CreatePartRequest” that sends the server the properties necessary for the server to create the part itself – I guess that’s the best way to do it…

#10

Even if you don’t clone it it won’t work. There is no way to pass objects to the server I guess, only the properties which can be used to recreate them.

#11

I’m pretty confident references to objects can be passed through remotes provided the fact that the Instance exists both on the client and the server. The object can’t be passed if it doesn’t exist on both as seen on the Wiki:

Non-replicated Instances

If the value being sent is only visible to the sender then nil will be passed instead of the value. For example, if a server tries to pass a descendant of ServerStorage, the client listening to the event will see nil passed as the value.

I believe this explains OP’s situation

I was talking about a part generated on the client, but yes it would probably work if it was already on the server, which I guess in this case would be fine since it’s a copy tool and it’s not generating the initial parts on the client

#13

Im gonna store all the copy-able parts in serverstorage, then when the copy tool needs to make changes, its gonna send over the name of the part, and the parts position. so in a weird way there are two of the same parts in the exact position with each between the client and server.

#14

You could just clone on the server, it’s redundant to clone on the client as well as the server since you’re duplicating the same action

#15

You cannot pass a reference to an object in ServerStorage to clients. Clients do not have access to ServerStorage. If you’re going with this method, put the parts in ReplicatedStorage.

#16

let me clearify, the localscript is in charge of dragging and placing the clients part, a normal script reading off the remote event is the one that handles the part made on the server.
