How to change the "end" of a circle

[silver4804]

thats what i already tried on the video, it just flipped it

[ghostreperlord]

no i changed the mouse position vector not the -1 or 1

@ghostreperlord

local RelativeDirection = (  self.UI.CoordinateSystem.AbsolutePosition-getPosition()).Unit
		
		local Degrees = math.deg(math.acos(RelativeDirection.Y)) 
		if math.sign(RelativeDirection.X)  == 1 then
			Degrees = 360 - Degrees
		end
		
		
		self.UI.DisplayVector.Arrow.Position = UDim2.new(0, 50*RelativeDirection.X, 0, 50*RelativeDirection.Y) + self.UI.CoordinateSystem.Position
		self.UI.DisplayVector.Arrow.Rotation = -Degrees
		local degPerSegment = 360 / 8

		for i, v in ipairs(self.slots) do
			if Degrees <= i * degPerSegment then
				print(`selecting {i}`)
				
				break
			end
		end
		
		print(Degrees)

bro thank you, finally

BTW something i noticed
your mouse position function has to be cooked because (mouse pos - other pos)
should be the vector pointing from other pos to mouse pos
instead it seems that your mouse pos is the inverse of what it should be for whatever reason.
please give me the solution mark though I have 0 solutions
edit:
thank you :3
