How to lock the character's Y orientation in water

I’m looking for a method to lock the player character’s Z and X axes when they step in water, while keeping the Y axis free for regular directional movement, to create a more realistic swimming and wading mechanism - the intended effect is for the character to swim upright. By the way, using a custom rotated swim animation doesn’t exactly work (I can explain if needed.)

I’ve tried using a couple methods, notably such as AlignOrientations, but none seem to work. My attempt as is follows:

	local Attachment=Instance.new('Attachment')
	Attachment.Parent=char.HumanoidRootPart
	Attachment.Name='SwimAttachment'

	local LV=Instance.new('AlignOrientation')
	LV.Parent=Attachment
	LV.RigidityEnabled=true
	LV.Enabled=true

	LV.Attachment0=Attachment
	LV.Attachment1= PartAttachment
	LV.Mode=Enum.OrientationAlignmentMode.OneAttachment
	
	game:GetService('RunService').Heartbeat:Connect(function()

		if Attachment 
		then
			
	
			LV.CFrame=CFrame.Angles(

				0,
				char.PrimaryPart.Orientation.Y,
			0,

			)
			
		end
		
	end)

So, does anyone have a fix or an alternative method? This issue relates to the default humanoid swimming state, which should honestly be toggled in the first place.

You could set the humanoid root part to the water’s y

I’m using terrain water at different heights so I’m not sure if this could work.

To anyone who sees this, I did sort of find a way to do this by automatically turning shift lock on in water, but this wasn’t my intended solution (it should be like the default non-shift lock movement) so I won’t mark it as answered.

(Sorry for the late reply :sweat_smile: )

Hello to anyone who happens to stumble across this, as I’ve found a solution. It works both server and client-sided.

Create an AlignOrientation in the character’s RootPart, and create a RunService function that runs either every heartbeat or step. Then, set the orientation’s CFrame to the following:

   local LV=char:FindFirstChild('SwimOrientation',true)

	local con=	game:GetService('RunService').Heartbeat:Connect(function()
		if  LV and char:FindFirstChild('Humanoid') and char.Humanoid.MoveDirection.Magnitude ~=0
			and char:FindFirstChild('HumanoidRootPart')
		then 
                     --Be sure to check if the character is in water, you could use Humanoid:GetState().
			LV.CFrame =CFrame.lookAt(char.PrimaryPart.Position - char.Humanoid.MoveDirection,char.PrimaryPart.Position)
		end
	end)

Enjoy!
