    The halo is in a wrong angle and im confused.

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    None atm.

Script:

local NHalo = script.Parent
local Number = 1
local cf = CFrame.new
local cfa = CFrame.Angles



game:GetService("RunService").Stepped:Connect(function(t)
	local tpi=t%math.pi
	local AP=cf(0,-1.5+math.sin(tpi)/8,0)*cfa(0,tpi,0)
	NHalo.AttachmentForward = NHalo.AttachmentForward + Vector3.new(1,0,0)
	NHalo.AttachmentPos = Vector3.new(0,0,-1)	
	NHalo.AttachmentPoint = AP
	end)

Have you tried adding 90 degrees to the values in cfa(0,tpi,0)

Yes this is the result

Since the halo is round why are you spinning it with the angle cfa(0,tpi,0)?
I’d think you just want it to bob up and down with AP=cf(0,-1.5+math.sin(tpi)/8,0) then put the cfa(0,0,90) without the variable or whatever works to rotate the mesh 90 degrees.
