Laggy camera problem

[addisonshiu]

I tried to make a first person camera function with 1 frame delayed to achieve the accelerate, decelerate and turning effect. But somehow it also produce a laggy camera effect.

Codes below:

local RunService = game:GetService("RunService")
local cam = workspace.CurrentCamera

function FirstPerson(haveDelay)
		
	local saveCam;
	
	RunService:BindToRenderStep("DrivingCamFirstPerson", Enum.RenderPriority.Camera.Value, function(dt)
		cam.CameraType = "Scriptable"
		
		local hhead = game.Players.LocalPlayer.Character.Head
		local rx, ry, rz  = hhead.CFrame:ToOrientation()
		local newcor =  CFrame.new(hhead.Position) * CFrame.fromOrientation(0, ry, rz) --remove angle x from the original cframe
		if haveDelay then
			if saveCam then
				cam.CFrame = saveCam --use the last CFrame
			end
			saveCam = newcor --save the camera CFrame
		else
			cam.CFrame = newcor
		end
	end)
end

From using FirstPerson(false) (First person camera without delay effect), the camera move smoothly

FirstPerson(false)

But for FirstPerson(true) (First person camera with delay effect), the camera move laggy.

FirstPerson(true)

Any ways to solve this problem? Thank you.

Make sure you are lerping to the new camera CFrame.

I believe there will still be a very small stutter, but I think that happens because there is no tick compensation or something?

Don’t quote me on that, seriously. I don’t really know what the cause is off the top of my head, but I had read about it somewhere.

Heres some help, utilize springs/dampening. Why? Think of it as this (I saw somebody explain this), if you’re moving the camera over and over to another part on lerp it’d keep changing as it moves meaning it never actually has any “velocity” to the camera, its just triyng to follow where you’d assign it.

Now if you were to use springs, it will keep moving forward smoothly until you stop or it finally reaches the destination. This allows for smooth camera movement, you can check this post out to help you:

Camera stutters while interpolating at high velocities

I’m trying to interpolate the camera to follow a target part, which works great at low speeds(for the most part), but trying to follow anything going at a decent speed causes the part to appear as if it’s stuttering. Here’s some examples:

(Its old but it will help, just search for the replies with dampening and springs)

Heres it in action and uncopylocked:

Hover car physics stuttering?

How about this place? JudderRepro-UseRunServiceSteppedDtInsteadOfRenderStepped.rbxl (414.9 KB) The only change is that in the spring equation instead of using RenderStepped’s dt, I use RunService.Stepped:wait() dt, which should actually track the different amount of work physics step does from frame to frame.

The spring method works but it is not suitable in my situation, mine is first person view and there are things at the back. The camera will clipped into the wall and go to the back of the vehicle if the speed is too fast which is not realist as first person driver.

If I’m not mistaken, they use springs/dampening in first person cameras. You just need to alter the settings and so on for it to work correctly in your game. (though I may be wrong )

I tried set spring.omega to a really high value but the stuttering happened again
