Open Source Camera Manipulation GUI

For this script, you will need a part named "CamPart" or you can change the variable to your desired part in workspace. Make sure the part is anchored, and transparent. This is a local script inside a screengui.

local Camera = game.Workspace.CurrentCamera
local Client = game.Players.LocalPlayer
local CameraPart = game.Workspace.CameraPart

repeat wait() until Client.Character

Camera.CameraType = "Scriptable"
Camera.CFrame = CameraPart.CFrame

There is also ways to make this rotate, and etc. Thats just using basic velocity math on your camera part though.
