RunService.RenderStepped:Connect(function()
	ViewModel.Torso.CFrame = Camera.CFrame  -- Set viewmodel cframe to camera cframe
	if Character:FindFirstChildWhichIsA("Tool") and Humanoid.MoveDirection.Magnitude > 0 then
        -- player is moving with a tool equipped
		local currentCF = Camera.CFrame

		local x = math.cos(tick() * 3) * 0.2
		local y = math.abs(math.sin(tick() * 5)) * 0.1

		local cf = currentCF * CFrame.new(x, y, 0)

The gun bobbing here works perfectly fine in my fps viewmodel, however once the player stops moving, it immediately goes back to the camera cframe which looks very jarring.

I had originally tried using the given example in this article to shift the viewmodel back smoothly.
(This part specifically)

humanoid.CameraOffset = humanoid.CameraOffset * 0.75

But I can’t apply this example to CFrames. Are there any other possible solutions?

Maybe try to lerp the CFrame to the Camera CFrame

ViewModel.Torso.CFrame = ViewModel.Torso.CFrame:Lerp(Camera.CFrame,0.07)

I’m not sure what’s the problem here, but if you want to, you should just use the spring module for bobbing. I can give you the bobbing code example if you’d like to.

Go ahead, although I try to avoid springs as I don’t understand them as well.

It’s not that hard, you just make a new instance with module.new() and do things.

Ok, first thing is get the module and put it in replicated storage and create a new instance.

local spring = require(game.ReplicatedStorage.SpringModule)
local bobbing = spring.new()

Then here’s a simple function I made for the bobbing.

local function Bobbing(addition)
	return math.sin(tick() * addition * 1.3) * 0.5 -- Increase the multiplication to make it faster!
end

Now you can simply do this.

game:GetService("RunService").RenderStepped:Connect(function(dt)
       local bob = Vector3.new(Bobbing(10),Bobbing(5),Bobbing(5))
       bobble:shove(bob / 10 * (char.HumanoidRootPart.Velocity.Magnitude / 10))
       local updatebob = bobble:update(dt)
       viewmodel.HumanoidRootPart.CFrame  = viewmodel.HumanoidRootPart.CFrame:ToWorldSpace(CFrame.new(updatebob.Y, updatebob.X, 0))
end)

This is the code that how I use and make my viewmodel, you can edit it according to your dependencies.

Hope it helps. :smiley:

What exactly is bobble in the script?

#7

Bumping the post. Don’t leave me hanging man

#8 
viewmodel.HumanoidRootPart.CFrame  = viewmodel.HumanoidRootPart.CFrame:ToWorldSpace(CFrame.new(updatebob.Y, updatebob.X, 0))

This line bobbles.

Sorry for late reply.
You can replace HumanoidRootPart with Torso or whatever your viewmodel has.

I mean this line, you never define it in your previous post, what is bobble?

#10

That’s the instance that we created with spring.new()

#11

Wait what is the spring module you’re referring to? Is it this one?

#12

SpringModule.rbxm (1.3 KB)
Take this module. Just drag and drop it in the explorer tab on your studio.

Should be the same.
