Help me out with this radar | Roblox Studio Community | Page 1

So the problem is, as shown in the clip, the radar moves in a sine-wave pattern from the origin, but it’s supposed to stay centered while rotating

local Radar = script.Parent.Parent

local Trace = Radar.Trace
local Radio = Radar.Size.X.Scale/2
local pi = math.pi

local xs = 0.5
local ys = 0.5
-- Centra el trace en el medio del radar
Trace.AnchorPoint = Vector2.new(0, 0.5)
Trace.Position = UDim2.new(0.5, 0, 0.5, 0)  -- punto de rotación: centro izquierdo

Trace.Size = UDim2.new(0.5, 0, 0.01, 0)  -- largo medio del radar, grosor pequeño



local x = (xs/0.5) * 2 - 1
local y = ((ys-0.25)/0.5) * 2 - 1

while task.wait() do
    Trace.Rotation += 1
local getx = math.cos(Trace.Rotation * pi/180)
local gety = math.sin(Trace.Rotation * pi/180)

    local xi = ((getx + 1) / 2) * 0.5
    local yi = ((gety + 1) / 2) * 0.5 + 0.25

Trace.Size = UDim2.new(1/2,0,0.01,0)
Trace.Position = UDim2.new(xi,0,yi,0)
Trace.Position = Trace.Position 


local perimeter = 2 * pi * Trace.Size.X.Scale
local Rootation = pi/2

end 
--print(perimeter)
--print(Trace.Position.Y.Scale)
--print("grade:"..math.atan(y/x) * 180/pi)
--print("grade2:"..math.atan(gety/getx) * 180/pi)
--              y     x
--print(x)
--print(y)

--print("----")
--print("x: "..xi)
--print("y: "..yi)

--print(getx)
--print(gety)

--print("----")

--print(((getx + 1) / 2) * 0.5)
    --print((xi/0.5) * 2 - 1)
