Script not able to move model; "Position is not a valid member of Model"

#1

For some reason, my script that tries to move a model keeps saying that the “Position” isn’t a valid member of “[model name]”

the model.Position += Vector3.new(0,0.05,0)

Is there a way to fix this issue?

Hello, Yes I had a similar problem too, you have to set the primary part

You can use 2 solution

  1. Manual PrimaryPart

  2. Select the model in the Explorer.

  3. In the Properties pane, you’ll see a property named PrimaryPart. Click on the dropdown next to it.

  4. You’ll see a list of all the parts within the model. Select the part you want to set as the PrimaryPart.

  5. Use Setting the PrimaryPart using a Script:

local model = game.Workspace.YourModelName -- Replace with the path to your model
model.PrimaryPart = model.PartName -- Replace 'PartName' with the name of the part you want to set as the PrimaryPart

Just in case start debugging If won’t work:

local model = game.Workspace.YourModelName -- Replace with the path to your model
if model.PrimaryPart then
    model:SetPrimaryPartCFrame(model.PrimaryPart.CFrame + Vector3.new(0, 0.05, 0))
else
    warn("Model does not have a PrimaryPart set!")
end


local model = game.Workspace.YourModelName -- Replace with the path to your model
for _, part in ipairs(model:GetChildren()) do
    if part:IsA("BasePart") then
        part.CFrame = part.CFrame + Vector3.new(0, 0.05, 0)
    end
end

Tried it, didn’t work out too well.

--server (ServerScriptService)--

local REP = game:GetService("ReplicatedStorage")
local RS = game:GetService("RunService")

local remote = REP.Lift

local Vehicle = game.Workspace.Mover.Vehicle
local Move

for _, part in ipairs(Vehicle:GetChildren()) do
	if part:IsA("BasePart") then
		part.CFrame = part.CFrame + Vector3.new(0, 0.05, 0)
	end
end

remote.OnServerEvent:Connect(function(plr, state)
	Move = state
end)
#4

Okay, any error codes?

Ensure the Vehicle Exists :

local Vehicle = game.Workspace:WaitForChild("Mover"):WaitForChild("Vehicle")

Use the Remote Event

local Move = false

remote.OnServerEvent:Connect(function(plr, state)
    Move = state
end)

while wait(0.1) do -- This will loop every 0.1 seconds
    if Move then
        for _, part in ipairs(Vehicle:GetChildren()) do
            if part:IsA("BasePart") then
                part.CFrame = part.CFrame + Vector3.new(0, 0.05, 0)
            end
        end
    end
end

Client Side :

local remote = game.ReplicatedStorage.Lift

-- Example: To start moving the vehicle
remote:FireServer(true)

-- Example: To stop moving the vehicle
remote:FireServer(false)

Make sure that the part has a primarypart manually and If none of those worked let’s start debugging

I’ll support you with the client side and the image of the model itself.

--client (StarterPlayerScripts)--

local REP = game:GetService("ReplicatedStorage")
local UIS = game:GetService("UserInputService")

local remote = REP.Lift

UIS.InputBegan:Connect(function(input, gp)
	if gp then return end
	if input.KeyCode == Enum.KeyCode.E then
		remote:FireServer(true)
	end
end)

UIS.InputEnded:Connect(function(input, gp)
	if gp then return end
	if input.KeyCode == Enum.KeyCode.E then
		remote:FireServer(false)
	end
end)

Nothing shows up on the output either. (the movement is done via keybind by the way)

#6

Can’t you just move it’s pivot? It’s like CFrame on models

Vehicle:SetPivot(Vehicle:GetPivot() * CFrame.new(Vector3.new(0, 0.05, 0)))
#7

Just use SetPivot() and give it a CFrame instead of a Vector3

#8

SetPrimaryPartCFrame is deprecated.

#9

Model:PivotTo(targetCFrame) is the easiest way to move models. For consistency it would be best to have a primarypart set too, as the pivot is otherwise calculated as the centre of the group of parts (which could change).
