How would I Move a Model, but also Change it's Rotation?

[kavi_conner (Kavi)]

Hello Developers,

I am currently working on a system that allows players to move a Model. With that system, I want to make it so players can rotate said Model.

For moving the Model, I am using Model:PivotTo(). But the issue comes when I rotate my Model and move my mouse. When rotating the Model, I am not taking in account of the rotation. So, it “Resets” the rotation applied.

Problem solved, right?- Nope.

Because I’m working with stuff which I don’t fully understand. (Cough Math Cough)

TLDR:

My Model’s rotation is being reset when I move my mouse.

Code

(Local Script)

-- // Services // --
local Players = game:GetService("Players")
local UserInputService = game:GetService("UserInputService")

-- // Variables // --
local Booth = workspace:WaitForChild("TheGenericBooth")
local ZeroBuildZone = workspace:WaitForChild("ZeroBuildZone")

local maxDistance = 1000
local Mouse = Players.LocalPlayer:GetMouse()



-- // Functions // --
local function getWorldMousePosition()
	
	-- Params --
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Exclude
	params.FilterDescendantsInstances = { Players.LocalPlayer.Character, workspace.TheGenericBooth }
	
	-- Raycast --
	local mouseLocation = UserInputService:GetMouseLocation()
	local screenToWorldRay = workspace.CurrentCamera:ViewportPointToRay(mouseLocation.X, mouseLocation.Y)
	
	local directionVector = screenToWorldRay.Direction * maxDistance
	local raycastResult = workspace:Raycast(screenToWorldRay.Origin, directionVector, params)
	
	-- Return --
	return raycastResult
	
end





-- // Mouse // --
Mouse.Move:Connect(function()
	local Cast = getWorldMousePosition()
	local Success, Error = pcall(function()
		local NewPivot = CFrame.new(Cast.Position) + (Booth.PrimaryPart.Size/2 * Cast.Normal)
		Booth:PivotTo(NewPivot)
	end)
	
	if not Success then
		print(Error)
	end
end)

Mouse.Button1Down:Connect(function()
	
	-- Variables --
	local BoundingBox = ZeroBuildZone:GetBoundingBox()
	local Region = Region3.new(ZeroBuildZone.PrimaryPart.Position - 0.5 * ZeroBuildZone.PrimaryPart.Size, ZeroBuildZone.PrimaryPart.Position + 0.5 * ZeroBuildZone.PrimaryPart.Size)
	local PartsInRegion = workspace:GetPartBoundsInBox(ZeroBuildZone.PrimaryPart.CFrame, ZeroBuildZone.PrimaryPart.Size)
	
	-- Print Parts in Zero Build Zone --
	for a, Part: BasePart in pairs(PartsInRegion) do
		if Part.Name == "BoothBorder" then
			print(Part.Name)
		end
	end
	
	
end)





-- // Rotation // --
local function RotateBooth()
	
	-- Variables --
	local rotation = CFrame.Angles(0, math.rad(90), 0)
	local modelCFrame = Booth:GetPivot()
	Booth:PivotTo(modelCFrame * rotation)
	
end

UserInputService.InputBegan:Connect(function(Input: InputObject, GPE: boolean)
	if Input.UserInputType == Enum.UserInputType.Keyboard then
		if Input.KeyCode == Enum.KeyCode.R or Input.KeyCode == Enum.KeyCode.Right then
			RotateBooth()
		end
	end
end)

So… you get the bounding box from the model, offset it with the mouse position, and then offset it with cframe.angles() and the whole thing would be like:

Model:GetBoundingBox().Position*CFrame.new(MousePosition)*CFrame.angles(math.rad(45),0,0) -- Offsets the rotation by 45° on the X axis

Unfortunately I got the error

invalid argument #1 (CFrame expected, got Vector3)

Which I believe it’s because I use Cast.Position where you said MousePosition.

My bad! I put Model:GetBoundingBox().Position expecting it would output the cframe without the rotation but it outputted a vector3, what you can do is replace Model:GetBoundingBox().Position with CFrame.new(Model:GetBoundingBox().Position)
