How to add limits for alignOrientation

[famse32 (mr_Fishman)]

I am trying to create a code which will rotate given part in direction of players mouse using alignOrientation. That’s easy but how do i add limits for rotation? Let’s imagine that we need to let part freely rotate on Y axis but make it unable to rotate for more than 45 degrees in both up and down on x axis.

I already tried to do it through geting orientation from :ToOrientation(), clamping by math.clamp() and returning in CFrame.Angles but it only follow limits when facing world front direction. In other case it gives unexpected rotation. And yes I was including difference between radians and degrees.

Here is the part of the code that is responsible for this

--CFrame which will rotate part without including limits
local potentialCFrame = CFrame.lookAt(helicopterRoot.Position, lookPosition.Position)
local pitch, yaw, roll = potentialCFrame:ToOrientation()
local orientationVector = Vector3.new(
	math.deg(pitch),
	math.deg(yaw),
	math.deg(roll)
	)
--Clamped orientation which in theory must be ok
alignOrientation.CFrame = CFrame.Angles(
    math.rad(math.clamp(orientationVector.X,-45,45)),
    math.rad(orientationVector.Y),
    math.rad(orientationVector.Z)
)

English isn’t my native language so be aware of misundarstanding. I will be happy to hear any response!

you’d have to apply the ‘limit’ relative to the direction the player is facing (or something like that)
how you do that is something i can’t tell you though

local rootPos = helicopterRoot.Position
local targetPos = lookPosition.Position
local dir = (targetPos - rootPos).Unit
local yAxis = Vector3.new(0, 1, 0)

local yawCFrame = CFrame.new(Vector3.zero, Vector3.new(dir.X, 0, dir.Z))
local localDir = yawCFrame:Inverse():VectorToObjectSpace(dir)
local pitch = math.asin(math.clamp(localDir.Y, -math.sin(math.rad(45)), math.sin(math.rad(45))))

alignOrientation.CFrame = yawCFrame * CFrame.Angles(pitch, 0, 0)

This should work regardless of world-facing direction and avoids the gimbal issue.
