How can I move the part smoothly into position?

How can I make the camera move smoothly to the position of the script?

How do I make the camera move from where it stayed still to the new position?
and return to the position where the camera was before the new position?

whis is my code:

-- LOCALS --

-- Services
local uis = game:GetService("UserInputService")
local rs = game:GetService("RunService")
local context = game:GetService("ContextActionService")

-- Player & Character
local plr = game:GetService("Players").LocalPlayer

-- Other
local Camera = game:GetService("Workspace").CurrentCamera
local mouse = plr:GetMouse()
local cameraDB = false
local zoomDB = false

-- Values

local xAngle = 0
local yAngle = 0
local cameraPos = Vector3.new(2,0,3.5)


-- CAMERA SETTING --

wait(0.01)
Camera.CameraType = Enum.CameraType.Scriptable

-- FUNCTIONS --

context:BindAction("CameraMovement", function(_,_,input)
	xAngle = xAngle - input.Delta.x*0.4
	yAngle = math.clamp(yAngle - input.Delta.y*0.4,-80,80)
end, false, Enum.UserInputType.MouseMovement)

rs.RenderStepped:Connect(function()
	local c = plr.Character or plr.CharacterAdded:Wait()
	local rootPart = c:FindFirstChild("HumanoidRootPart")
	
	if c and rootPart then
		local startCFrame = CFrame.new((rootPart.CFrame.p + Vector3.new(0,2,0)))*CFrame.Angles(0, math.rad(xAngle), 0)*CFrame.Angles(math.rad(yAngle), 0, 0)
		
		local cameraCFrame = startCFrame + startCFrame:VectorToWorldSpace(Vector3.new(cameraPos.X,cameraPos.Y,cameraPos.Z))
		local cameraFocus = startCFrame + startCFrame:VectorToWorldSpace(Vector3.new(cameraPos.X,cameraPos.Y,-50000))

		Camera.CFrame = CFrame.new(cameraCFrame.p,cameraFocus.p)
	end
end)```

Shouldn’t you just use tweenservice with easing to make it smooth?

Hi, you could accomplish this with TweenService. I have left a couple recourses below as it is kind of confusing to understand.

Best of luck on your game! Tell me if you need help with anything else.

As @AnotherScriptStudio mentioned, you can use TweenService another possibility is to use CFrame:lerp. You could use Vector3:lerp, but CFrame accounts for the rotation and the position of the camera, so usually it’s your best option. So something like this:

local targetCframe = CFrame.lookAt(Vector3.new(2,0,3.5), Vector3.new(0,0,0)) -- CFrame.lookAt(position, lookat position)
local step = 0

local rstep
rstep = rs.RenderStepped:Connect(function(t)
	step += t

	Camera.CFrame = Camera.CFrame:Lerp(targetCframe, step)

	if step >= 1 then
		rstep:Disconnect()
	end
end)

I considered adding videos for that too but I decided not to because @skowdash mentioned they wanted to move the parts smoothly so I thought the transition options could be helpful to find the intended style that matches the game. In addition, I think that most people should try to learn tweening first because if you try to learn lerping first you could over-simplify a tween if you try to learn it later. Overall, both options should work.

Yes, I do agree that everyone should learn Tweening. However, as you said, it can be confusing to learn at first and also takes time to learn. Because Lerping is a simple concept to quickly learn, and the code shown in the original post displays an understanding of Iteration so I figured it’d be the easiest to implement in the pre-existing code.

Honestly you should just use TweenService, it’s quite simple and a lot more simpler and organized to control.
