How would I make the camera follow the mouse

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to make the player’s camera follow where he is pointing his mouse
  2. What is the issue? Include screenshots / videos if possible!
    I can’t seem to make the camera follow the mouse’s position.
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I have tried looking at the dev forums and topics similar to it and even YouTube videos.

Make camera behave like RMB is held, without actually holding RMB

I didn’t look much through your code block, but here is the general idea:

  • Make a CFrame position for the camera with the “at” position and the “lookAt” position (aka position to look towards)
  • Get the lookAt position with Mouse.Hit
  • IDK where you want your at position to be, below I have it at the camera’s position

Example:

local Workspace = game:GetService("Workspace")
local RunService = game:GetService("RunService")

local camera = Workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable

RunService.RenderStepped:Connect(function()
	local hit = Mouse.Hit
	if not hit then
		return
	end
	local lookAt = hit.Position
	local at = camera.CFrame.Position
	camera.CFrame = CFrame.new(at, lookAt)
end)

So for your last bullet. I just want the position to be at the mouse’s position. How would I do that?

#4

Let me rephrase that, you have two positions:

  • One where the camera is at, kind of like where the eyes are
  • And another where the camera is looking at, kind of like what the eyes are focusing on

To get the position where the mouse is, use Mouse.Hit.Position. Remember to check if the Hit CFrame exists first though :+1:

To make a cframe from where the camera is at and what it should be looking at, use: CFrame.new(at, lookingAt)

This is what happens when I make at the root part

I’m trying to make it so that it is maybe a bit behind this

This is a vortex that I bring from replicated storage by pressing “J” how do I make it so that my camera follows where I’m going to. I can’t make the “at” the vortex because this is in the local script so there is no way for me to call on it
