Ignore Y orientation on CFrame.lookat

#1

i know this is sorta a duplicate but all the posts i found made no sense

so i have a while loop that makes an npc look at the player but if the player goes up and down this happens

the npc goes up and down looking at the player too which looks really weird
how could i make it not go up and down? just x and z
sorry for the rather bad explanation

local at = character.PrimaryPart.Position
local lookAt = npc.PrimaryPart.Position

-- change lookAt Y axis to be the same as at
lookAt = Vector3.new(lookAt.X, at.Y, lookAt.Z)

character.PrimaryPart.CFrame = CFrame.lookAt(at, lookAt)

Part rotation alignment

Alternative method:

local x, y, z= CFrame.lookAt(something1,something2):ToOrientation()
local newCFrameLookAt = CFrame.fromOrientation(0,y,z)

do you happen to know how to prevent it from spinning if there is a player below it?

local at = character.PrimaryPart.Position
local lookAt = npc.PrimaryPart.Position

-- change lookAt Y axis to be the same as at
lookAt = Vector3.new(lookAt.X, at.Y, lookAt.Z)

-- if the distance is less then 0.5 studs exit
if (lookAt - at).Magnitude < 0.5 then return end

character.PrimaryPart.CFrame = CFrame.lookAt(at, lookAt)

Change the 0.5 to match your requirements
