Weird CFrame.lookAt() bug

[Kilpamations (Kilp)]

Hello
I am experiencing a weird bug with CFrame.lookAt(). When I type this line of code:

char.HumanoidRootPart.CFrame = CFrame.lookAt(char.HumanoidRootPart.Position, Vector3.new(aimatt.WorldPosition.X, aimatt.WorldPosition.Y, aimatt.WorldPosition.Z))

It works (but it rotates the character up which is not what I want)
However, when I type this out:

char.HumanoidRootPart.CFrame = CFrame.lookAt(char.HumanoidRootPart.Position, Vector3.new(aimatt.WorldPosition.X, aimatt.WorldPosition.Y, 1))

Nothing happens; the character just stays in place and doesn’t rotate towards the attachment.
Thank you for your help in advance

Judging off of your code, if you want your character to face aimatt.WorldPosition, here is what you could do:

local hPos = char.HumanoidRootPart.Position
local aPos = aimatt.WorldPosition
char.HumanoidRootPart.CFrame = CFrame.lookAt(hPos, Vector3.new(aPos.X, hPos.Y, aPos.Z))

Basically, this code will make the HumanoidRootPart face the target position on the X and Z axes (left/right, forward/back), and the HumanoidRootPart’s position on the Y axis, so that it does not face up or downwards towards the target.

Hopefully this helps. Let me know if you had any other questions!
