How to manually allow player to zoom in/zoom out

Help and Feedback Scripting Support
#1

Hello everyone, I am making a 2D-esque type of game. I made a script that locks the camera behind the player, so it feels more like a 2D game. However, I still want the player to be able to zoom in and out, but I do not know how to do this. My script is as follows:

local CAMERA_OFFSET = Vector3.new(-15,20,0)


camera.CameraType = Enum.CameraType.Scriptable

local function onRenderStep()
	
	if player.Character then
		local playerPosition = player.Character.HumanoidRootPart.Position
		local cameraPosition = playerPosition + CAMERA_OFFSET

		-- make the camera follow the player
		camera.CoordinateFrame = CFrame.new(cameraPosition, playerPosition)
	end
end

RunService:BindToRenderStep("Camera", Enum.RenderPriority.Camera.Value, onRenderStep)

You can change the camera offset every time the player uses the scroll wheel

You can achieve this by listening for mouse wheel movement then directly changing “CAMERA_OFFSET” to make the camera zoom in or out.

The script I gave you also has clamping which stops the camera from zooming too in or too far.

local UIS = game:GetService("UserInputService")
local PS = game:GetService("Players")
local RNS = game:GetService("RunService")

local CAMERA_OFFSET = Vector3.new(-15,20,0)
local player = PS.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local HRP = char:WaitForChild("HumanoidRootPart")
local camera = workspace.CurrentCamera

local function OnRenderStep()
	if char then
		local playerPos = HRP.Position
		local camPos = playerPos + CAMERA_OFFSET

		camera.CFrame = CFrame.new(camPos, playerPos)
	end
end

local function OnScrollWheel(input)
	if input.UserInputType == Enum.UserInputType.MouseWheel then
		local pos = input.Position.Z
		local x,y
		
		if pos > 0 then
			x, y = CAMERA_OFFSET.X + -.5, CAMERA_OFFSET.Y + .5
			CAMERA_OFFSET = Vector3.new(if x < -5 and x > -20 then x else CAMERA_OFFSET.X, if y > 10 and y < 25 then y else CAMERA_OFFSET.Y, 0)
		else
			x, y = CAMERA_OFFSET.X - -.5, CAMERA_OFFSET.Y - .5
			CAMERA_OFFSET = Vector3.new(if x < -5 and x > -20 then x else CAMERA_OFFSET.X, if y > 10 and y < 25 then y else CAMERA_OFFSET.Y, 0)
		end
	end
end

UIS.InputChanged:Connect(OnScrollWheel)
RNS:BindToRenderStep("Camera", Enum.RenderPriority.Camera.Value, OnRenderStep)

This doesn’t seem to work for me…


It moves the camera up and down instead. Also, I put this in the invisicam script so I could have invisicam while still being able to customize the camera, although that shouldn’t change anything.

edit: Actually, I just tried it in a blank baseplate, and it worked…
