Camera Controller

Help and Feedback Scripting Support
#1

I’m using a custom camera controller provided by @Programm_Bot some time ago.

I have been making progress on my game over time however I’m now at a point of defining the finer things -
The method of the custom Camera works perfectly; however my issue is understanding the Theta and Phi to have it always match the Players when the Module is enabled.
Currently each time it resets to 0, 0 whenever it’s loaded due to it being custom.
I’m not too familiar with Camera CFrame despite working through DevForum to find a method I have been unsuccessful.

Can anyone perhaps shed some light :confused:
Thank you!
Code is:

	
	local Core = { ... }
	local Server, Script = game, script
	
	-- Setting up the script
	local UserInputService = game:GetService("UserInputService")
	local RunService = game:GetService("RunService")
	
	local currentCamera = workspace.CurrentCamera
	
	local subjectPosition = Vector3.zero 
	
	local userGameSettings = UserSettings():GetService("UserGameSettings")
	local mouseSensitivitySetting = userGameSettings.MouseSensitivity
	
	local sensitivity = (mouseSensitivitySetting / 2) / 2
	local radius = 0.5
	local theta = 0
	local phi = 0
	
	function SphericalCoordinate(r: number, theta: number, phi: number)
		local Position = Vector3.new(
			r * math.sin(phi) * math.cos(theta),
			r * math.cos(phi),
			r * math.sin(phi) * math.sin(theta)
		)
		
		local Hat_r = Vector3.new(
			math.sin(phi) * math.cos(theta),
			math.cos(phi),
			math.sin(phi) * math.sin(theta)
		)
		
		local Hat_theta = Vector3.new(
			-math.sin(theta),
			0,
			math.cos(theta)
		)
		
		local Hat_phi = Vector3.new(
			math.cos(phi) * math.cos(theta),
			-math.sin(phi),
			math.cos(phi) * math.sin(theta)
		)
		
		return {
			Position = Position,
			UpVector = -Hat_phi,
			LeftVector = Hat_theta,
			FrontVector = -Hat_r,
			DownVector = Hat_phi,
			RightVector = -Hat_theta,
			BackVector = Hat_r
		}
	end
	
	UserInputService.InputBegan:Connect(function(input: InputObject, gameProcessedEvent: boolean)
		if gameProcessedEvent then return end
		if input.UserInputType ~= Enum.UserInputType.MouseButton2 then return end
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
	end)
	
	UserInputService.InputEnded:Connect(function(input: InputObject, gameProcessedEvent: boolean)
		if gameProcessedEvent then return end
		if input.UserInputType ~= Enum.UserInputType.MouseButton2 then return end
		UserInputService.MouseBehavior = Enum.MouseBehavior.Default
	end)
	
	function Core:SetPos(v3, Offset, ...)
		subjectPosition = v3
		radius = Offset
	end
	
	function Core:Enable(...)
		currentCamera.CameraType = Enum.CameraType.Scriptable
		
		Core['Run'] = RunService.RenderStepped:Connect(function()
			local delta = UserInputService:GetMouseDelta()
			
			theta = (theta + delta.X * sensitivity) % 360 -- Left and right
			phi = math.clamp(phi - delta.Y * sensitivity, 0, 180) -- Up and down
			
			local sphericalCoordinate = SphericalCoordinate(
				radius,
				theta * math.pi / 180, 
				phi * math.pi / 180
			)
			
			currentCamera.CFrame = CFrame.fromMatrix(
				sphericalCoordinate.Position + subjectPosition, 
				sphericalCoordinate.RightVector, 
				sphericalCoordinate.UpVector, 
				sphericalCoordinate.BackVector
			)
		end)
	end
	
	function Core:Disable(...)
		pcall(function(...)
			Core['Run']:Disconnect(...)
		end)
	end
	
	return Core
