Player camera breaking when player collides with part

Help and Feedback Scripting Support
#1

I am making a camera script for my third person shooter, and it works well until the player collides with a wall. When the player collides with anything that is at an angle, the character rotates, but not the camera, and the camera is supposed to be behind the character at all times.

Here is the script:

local Players = game:GetService("Players")
local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local camera = workspace.CurrentCamera
local cameraOffset = Vector3.new(2.2, 1.8, 5)
local player = Players.LocalPlayer

local mouseMode = "locked"
local initialFunctionCalled = false

player.CharacterAdded:Connect(function(character)

	local humanoid = character:WaitForChild("Humanoid")
	local rootPart = character:WaitForChild("HumanoidRootPart")
	humanoid.AutoRotate = false
	
	
	local cameraAngleX = 7.5
	local cameraAngleY = 0

	local function playerInput(actionName, inputState, inputObject)
		-- Calculate camera/player rotation on input change
		if inputState == Enum.UserInputState.Change then
			cameraAngleX = cameraAngleX - inputObject.Delta.X
			-- Reduce vertical mouse/touch sensitivity and clamp vertical axis
			cameraAngleY = math.clamp(cameraAngleY-inputObject.Delta.Y*0.4, -75, 75)
			-- Rotate root part CFrame by X delta
			rootPart.CFrame = rootPart.CFrame * CFrame.Angles(0, math.rad(-inputObject.Delta.X), 0)
		end
	end
	ContextActionService:BindAction("PlayerInput", playerInput, false, Enum.UserInputType.MouseMovement, Enum.UserInputType.Touch)

	RunService.RenderStepped:Connect(function()
		if camera.CameraType ~= Enum.CameraType.Scriptable then
			camera.CameraType = Enum.CameraType.Scriptable
		end
		local startCFrame = CFrame.new((rootPart.CFrame.Position)) * CFrame.Angles(0, math.rad(cameraAngleX), 0) * CFrame.Angles(math.rad(cameraAngleY), 0, 0)
		local cameraCFrame = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, cameraOffset.Z))
		local cameraFocus = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, -10000))
		camera.CFrame = CFrame.new(cameraCFrame.Position, cameraFocus.Position)
	end)
end)
local function focusControl(actionName, inputState, inputObject)
	-- Lock and hide mouse icon on input began
	if inputState == Enum.UserInputState.Begin then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
		UserInputService.MouseIconEnabled =  false
		initialFunctionCalled = true
		ContextActionService:UnbindAction("FocusControl", focusControl, false, Enum.KeyCode.LeftAlt, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
	end
end
ContextActionService:BindAction("FocusControl", focusControl, false, Enum.KeyCode.LeftAlt, Enum.UserInputType.Touch, Enum.UserInputType.Focus)

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if initialFunctionCalled == true then
		if input.UserInputType == Enum.UserInputType.Keyboard then
			if input.KeyCode == Enum.KeyCode.LeftAlt then
				if mouseMode == "locked" then
					mouseMode = "unlocked"
					UserInputService.MouseBehavior = Enum.MouseBehavior.Default
					UserInputService.MouseIconEnabled = true
				elseif mouseMode == "unlocked" then
					mouseMode = "locked"
					UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
					UserInputService.MouseIconEnabled = false
				end

			end
		end
	end
end)

btw i tried messing around with Humanoid states and it didn’t work

thanks in advance! =D
