Camera CFrame orientation from Vector2, as MouseDelta

Help and Feedback Scripting Support
#1

Currently I’m working on a custom camera script, and I want to achieve proper camera rotation from a Vector2 as x and y values. I apologize if I’m stupid, but I don’t have much knowledge on Euler Angles.
The issue is about the camera rotation, I’ve tried many combinations between x, y and z by vector 2’s. Of course I used math.rad to fix degrees into CFrame rotations. Results has been the camera rotating in the wrong axes so far.

I’ve tried looking for solutions, but no helpful solutions so far.

Here’s the code I wrote for the custom camera. I use the code in a ModuleScript in the default PlayerScripts ModuleScript. The PlayerScriptsLoader script is modified to use the camPos to set the CurrentCamera’s CFrame every frame.

local plr = game.Players.LocalPlayer
local char

function updateChar()
	char = plr.Character or plr.CharacterAdded:Wait()
end

plr.CharacterAdded:Connect(updateChar)
updateChar()

local rs = game:GetService("RunService")
local uis = game:GetService("UserInputService")

local mouse2Down = false

uis.InputBegan:Connect(function(key, gp)
	if gp then return end
	local inputType = key.UserInputType
	if inputType == Enum.UserInputType.MouseButton2 then
		uis.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
		mouse2Down = true
	end
end)

uis.InputEnded:Connect(function(key, gp)
	if gp then return end
	local inputType = key.UserInputType
	if inputType == Enum.UserInputType.MouseButton2 then
		uis.MouseBehavior = Enum.MouseBehavior.Default
		mouse2Down = false
	end
end)

local module = {}
local self = setmetatable({}, module)

self.pos = self.pos or Vector3.new(0, 0, 0)
self.rot = self.rot or Vector2.new(0, 0)
self.camPos = self.camPos or CFrame.new(self.pos) * CFrame.Angles(self.rot.x, self.rot.y, 0)
self.smoothPos = self.smoothPos or Vector3.new(0, 0, 0)
self.smoothRot = self.smoothRot or Vector2.new(0, 0)
self.offset = self.offset or Vector3.new(0, 1.5, 0) --Head position
self.smoothPosModifier = self.smoothPosModifier or 8
self.smoothRotModifier = self.smoothRotModifier or 16
self.zoomMin = self.zoomMin or 0.5 --Stud
self.zoomMax = self.zoomMax or 10 --Stud
self.zoom = self.zoom or self.zoomMax --Stud
self.sensitivity = self.sensitivity or 0.05 --Real low lol

function update(dt)
	--Camera Positioning
	
	if char then
		local hrp = char:FindFirstChild("HumanoidRootPart")
		
		if hrp then
			self.pos = hrp.Position
		end
	end
	
	self.smoothPos = self.smoothPos + ((self.pos - self.smoothPos) * (dt * self.smoothPosModifier))
	
	--Camera Panning
	
	if mouse2Down then
		local delta = -uis:GetMouseDelta() * self.sensitivity
		self.rot = self.rot + Vector2.new(delta.y, delta.x)
	end
	
	self.smoothRot = self.smoothRot + ((self.rot - self.smoothRot) * (dt * self.smoothRotModifier))
	
	--Camera Result
	
	self.camPos = CFrame.new(self.smoothPos + self.offset) * CFrame.Angles(math.rad(self.smoothRot.y), math.rad(self.smoothRot.x), 0)
end

function start()
	rs:BindToRenderStep("CameraUpdate", Enum.RenderPriority.Camera.Value - 1, update)
end

function stop()
	rs:UnbindToRenderStep("CameraUpdate")
end

function self:Start()
	start()
end

function self:Stop()
	stop()
end

return self

I figured out how to do a correct rotation with X and Y by mouse delta.

	self.camPos = CFrame.new((self.smoothPos + self.offset)) * CFrame.Angles(0, math.rad(self.smoothRot.y), 0) * CFrame.Angles(math.rad(self.smoothRot.x), 0, 0)
