How to rotate orientation on one axis only using CFrame.LookAt

Hiya! I’ve been wanting to make a top down camera script and it’s been pretty simple so far but I hit a roadblock and that is that I need to only rotate the players humanoidrootpart on the Y axis but using CFrame.LookAt it’s rotating to look at the mouse on all axis.

The player rotation code:

RS.RenderStepped:Connect(function()
	camera.CFrame = (char.HumanoidRootPart.CFrame + offset) * CFrame.Angles(math.rad(-90), 0, 0)
	
	char.HumanoidRootPart.CFrame = CFrame.lookAt(char.HumanoidRootPart.Position, mouse.Hit.p) -- rotation on all axis!
end)

I would really appreciate help with this!

Hello.

I had actually done something similar and this is what worked for me.

CFrame.new(HumanoidRootPart.Position,Vector3.new(Mouse.hit.Position.X, HumanoidRootPart.Position.Y, Mouse.hit.Position.Z))

This works! Only problem I have now is that the player spins very quickly. Any idea on how to fix this?

You can make a tween and make the speed to your choice. (The number inside TweenInfo.new() )

local TweenService = game:GetService("TweenService")

local RootRotationTween = TweenService:Create(HumanoidRootPart,TweenInfo.new(1),{CFrame = CFrame.new(HumanoidRootPart.Position,Vector3.new(Mouse.hit.Position.X, HumanoidRootPart.Position.Y, Mouse.hit.Position.Z))})
RootRotationTween:Play()

You have to put the last two lines in the loop since the tween being created would need to use the current updated Root position and Mouse position.

Thank you so much for the well thought out reply but I actually found the problem! I used CFrame.new() instead and that seemed to fix the problem.

camera.CFrame = CFrame.new(char.HumanoidRootPart.Position + offset) * CFrame.Angles(math.rad(-90), 0, 0)

Funny thing is, now the player isn’t moving lol

Nvm fixed that! I just changed the rotation of the camera from -90 to -89. This seemed to do the job… I’m still kinda confused why it fixed it though.
