Hello, I would like to know how to make a smooth scroll to zoom system for my game!

I have been very confused lately on how to do it, I’ve tried Tweening it, and adding and subtracting the FOV it worked, but it wasn’t smooth.

Can anyone please help?

  • Here’s the code
connection2 = m.WheelForward:Connect(function()
							if cam.FieldOfView > 10 then
								if zoomTog == true then
									cam.FieldOfView = cam.FieldOfView - 1
									blurIn:Play()
									wait(0.25)
									blurOut:Play()
								end
							end
						end)

It doesn’t look like you are adding a debounce, and why don’t you tween the fov and blur

Have you tried using the TweenService to tween the FOV value?

I think you are looking for something similar to this?

UserInputService = game:GetService("UserInputService")
RunService = game:GetService("RunService")


local scrollSpeed = 1
local easeSpeed = .02
local fovTarget = 70
UserInputService.InputChanged:Connect(function(input)
	if input.UserInputType == Enum.UserInputType.MouseWheel then
		local up = input.Position.Z > 0 and 1 or -1
		
		fovTarget += up * scrollSpeed
	end
end)

RunService.Heartbeat:Connect(function()
	local camera = workspace:FindFirstChild("Camera")
	local fovCamera = camera.FieldOfView
	local fovDifference = fovTarget - fovCamera
	
	camera.FieldOfView += fovDifference * easeSpeed
end)

Here is a test place I set up for you to try this out:

  • scrollSpeed is unnessecary as you set it to just one

Use Tween Service.
If you’re looking for a mouse wheel input with a smooth zoom in, I recommend you using Tween Service to Tween FOV.
I Will link some tutorials below, if they’re any help to you let me know!

Well if you want the scrolling to be faster or slower you can change the scrollSpeed to 3 or 0.5 for example. Also useful if you have other modules that interact with these values (For example a Settings Module to adjust scrolling speed).
