Camera Main Menu Effect

Hello, so, I want to make an effect like this, but I have no idea how to do it

External Media

What I do is:

local Camera = workspace.CurrentCamera
local UIS = game:GetService("UserInputService")

local function get_mouse_pos_in_percentage()
    local mp = (UIS:GetMouseLocation()/Camera.ViewPortsize) - Vector2.one*0.5
    return mp
end

What this does is makes the mouse’s top-left corner (-1,-1), middle (0,0) and bottom-right (1,1) and then you can do:

local mp = get_mouse_pos_in_percentage()
local maxangle = 10
Camera.CFrame = CFrame.Angles(math.rad(mp.X*maxangle),math.rad(mp.X*maxangle),0)

and set the above code in a loop.

Where can I learn to do this type of calculation? I don’t want to have to resort to coming here every time I need to do a calculation

I don’t really know. Its quite simple honestly. Just google stuff.

[RuanFyze (Ruann)]

Yeah but, I would never know how to do that. I wouldn’t know that you need to calculate the screen or anything.

Well thats a bummer. Anyways if you need maths help then this site (Devforum) is perfect for you, because most of the maths here is out of my brain.
