Need help clamping the player’s horizontal camera angle relative to the direction the character is facing.

This is what I have so far:

```
local function normalizeang(X)
return (X >= math.pi and X - 2*math.pi) or (X <= -math.pi and 2*math.pi + X ) or X
end
--clamp x rotation :DDD
local _, y = Root.CFrame:ToOrientation()
y = -y
local rR = y + math.pi/2
local rL = y - math.pi/2
local rRnorm = normalizeang(rR)
local rLnorm = normalizeang(rL)
--if not, find closest bound and camera to said bound
if not ((X <= rRnorm and X >= rL) or (X >= rLnorm and X <= rR) or (X >= rRnorm and X <= rLnorm)) then
X = (math.abs(X - rR) < math.pi/2 and rRnorm or rLnorm)
end
X = normalizeang(X)
```

This almost works, however it experiences false positives when the camera and character rotates beyond 180 degrees. Any ideas on how I could restrict the angle?
