It now works
but it doesnt rotate the part/model like its supposed to
How is it supposed to rotate? What is it doing now?
It is not doing anything. In the code I want to be able to only show a specific model/part form the folder “Items” and have it rotate
local items = script.Parent:WaitForChild("Items")
local part = game.StarterGui.ScreenGui.shop.info.preview.Items.Anonymous_Desire
local vpf = script.Parent
part.Parent = items
items.Parent = vpf
local index, event = 1, nil
local camera = Instance.new("Camera")
camera.FieldOfView = 10
vpf.CurrentCamera = camera
vpf.Visible = true
-- rotation
local function setRotationEvent(model)
local currentAngle = 0
local modelCF, modelSize = model:GetBoundingBox()
local rotInv = (modelCF - modelCF.p):inverse()
modelCF = modelCF * rotInv
modelSize = rotInv * modelSize
modelSize = Vector3.new(math.abs(modelSize.x), math.abs(modelSize.y), math.abs(modelSize.z))
local diagonal = 0
local maxExtent = math.max(modelSize.x, modelSize.y, modelSize.z)
local tan = math.tan(math.rad(camera.FieldOfView/2))
if (maxExtent == modelSize.x) then
diagonal = math.sqrt(modelSize.y*modelSize.y + modelSize.z*modelSize.z)/2
elseif (maxExtent == modelSize.y) then
diagonal = math.sqrt(modelSize.x*modelSize.x + modelSize.z*modelSize.z)/2
else
diagonal = math.sqrt(modelSize.x*modelSize.x + modelSize.y*modelSize.y)/2
end
local minDist = (maxExtent/2)/tan + diagonal
return game:GetService("RunService").RenderStepped:Connect(function(dt)
currentAngle = currentAngle + 1*dt*40
camera.CFrame = modelCF * CFrame.fromEulerAnglesYXZ(0, math.rad(currentAngle), 0) * CFrame.new(0, 0, minDist + 3)
end)
end
local function addChildren()
script.Parent.Items:WaitForChild("Anonymous_Desire")
local part = game.StarterGui.ScreenGui.shop.info.preview.Items.Anonymous_Desire
part.Parent.Parent = vfp
end
--
vpf.InputBegan:Connect(function(input)
if (input.UserInputType == Enum.UserInputType.MouseButton1) then
end
end)
but rn it is just showing the model and it is not rotating it
You have to call the setRotationEvent function and pass in the model as an argument, Also is there a reason you add the model to the viewportframe at the beginning of the script but you have a function later to do that . i also notice some unnecessary bits and some other problems so here is a simplified version of your code, where you need to define a folder that needs to be in the viewportframe (folder to hold currently visible model) and one that is outside of the viewportframe (that holds object that cannot be seen) it’s essentially what egomoose (where it appears this function is from) provided in his post.
local VisibleItems = script.Parent.VisibleFolder ---- the EMPTY folder within the viewportframe
local HiddenItems = script.Parent.Parent.HiddenFolder --- the items that you want to be placed in the viewport frame at some point (root path)
local PrevModel
local CurrentEvent
local vpf = script.Parent
local camera = Instance.new("Camera")
camera.FieldOfView = 10
vpf.CurrentCamera = camera
vpf.Visible = true
local function setRotationEvent(model)
local currentAngle = 0
local modelCF, modelSize = model:GetBoundingBox()
local rotInv = (modelCF - modelCF.p):inverse()
modelCF = modelCF * rotInv
modelSize = rotInv * modelSize
modelSize = Vector3.new(math.abs(modelSize.x), math.abs(modelSize.y), math.abs(modelSize.z))
local diagonal = 0
local maxExtent = math.max(modelSize.x, modelSize.y, modelSize.z)
local tan = math.tan(math.rad(camera.FieldOfView/2))
if (maxExtent == modelSize.x) then
diagonal = math.sqrt(modelSize.y*modelSize.y + modelSize.z*modelSize.z)/2
elseif (maxExtent == modelSize.y) then
diagonal = math.sqrt(modelSize.x*modelSize.x + modelSize.z*modelSize.z)/2
else
diagonal = math.sqrt(modelSize.x*modelSize.x + modelSize.y*modelSize.y)/2
end
local minDist = (maxExtent/2)/tan + diagonal
return game:GetService("RunService").RenderStepped:Connect(function(dt)
currentAngle = currentAngle + 1*dt*40
camera.CFrame = modelCF * CFrame.fromEulerAnglesYXZ(0, math.rad(currentAngle), 0) * CFrame.new(0, 0, minDist + 3)
end)
end
local function Rotate(Model)
if CurrentEvent then
CurrentEvent:Disconnect()
end
if PrevModel then
PrevModel.Parent = HiddenItems
end
Model.Parent = VisibleItems
PrevModel = Model
CurrentEvent = setRotationEvent(Model)
end
Rotate(HiddenItems.ModelName) -- here is where you pass the hidden object so that it can be showen
And as an example of what i mean:

ok one more problem.
I have a car model inside the hiddenfolder.
and now it doesnt show
it says this
Camaro is not a valid member of Folder
Players.no_clu360.PlayerGui.ScreenGui.shop.info_frame.info_1.preview.LocalScript’, Line 57
line 57 on the script is this
Rotate(HiddenItems.Camaro)
its basically the bottom of the script u help me on
You are getting that error because Camaro isn’t in the Hidden-items folder when you tried to reference it. if this is because not everything is finished loading/replicating then just add a wait for child Rotate(HiddenItems:WaitForChild("Camaro"))
It now says
Infinite yield possible on ‘Players.no_clu360.PlayerGui.ScreenGui.shop.HiddenFolder:WaitForChild(“Camaro”)’
Script ‘Players.no_clu360.PlayerGui.ScreenGui.shop.info_frame.info_1.preview.LocalScript’, Line 57
Then it must not be in the folder when you are trying to reference it, make sure the model’s name is exactly Camaro. When in-game is the model in HiddenFolder?
I found the solution
it just had to much folders inside of the model.
Thanks for your help anyways.
