Aye, yo. I’m tryna get the angle (θ) (θ - greek small letter theta (u+03B8) copy and paste - Unicode® symbol)) from the direction of where the mouse has moved. I was thinking I have to use some sort of trigonometry. Thing is, I don’t know trigonometry. ;-; But here’s my initial thought;

What I have so far;

local player = game.Players.LocalPlayer

local mouse = player:GetMouse()

local center = Vector2.new(500,500)

local origPos
local endPos

mouse.Button1Down:Connect(function()
	origPos = Vector2.new(mouse.X, mouse.Y)
end)

mouse.Button1Up:Connect(function()
	endPos = Vector2.new(mouse.X, mouse.Y)
	
	local length = (endPos - origPos).Magnitude
end)

The angle itself would just be math.atan2(dy,dx), with dy and dx being the difference between endPos and origPos’s vector components.

Can u explain what dy and dx exactly are? :(( Thank you!

Ok. I solved it! Thanks for the help mate!

local player = game.Players.LocalPlayer

local mouse = player:GetMouse()

local origin
local endPos

mouse.Button1Down:Connect(function()
	origin = Vector2.new(mouse.X, mouse.Y)
end)

mouse.Button1Up:Connect(function()
	endPos = Vector2.new(mouse.X, mouse.Y)
	
	local length = (origin - endPos).Unit --idrk, i just called it length 
	
	local angle = math.deg(math.atan2(length.Y, length.X))
end)
