Making camera zoom in?

If you're making a sniper rifle, Using FoV isn't the best idea: FoV means Feild of View. Lowering it will make your view more narrow, causing you too see less. It's best to change the position of the camera, and maybe slightly changing the field of view.

So first, we want to detect the Right Mouse Button input and define the camera.

cam = game.Workspace.CurrentCamera --Assuming this is in a local script
mouse = game.Players.LocalPlayer:GetMouse() --Assuming this is in a local script

mouse.Button2Down:connect(function() --Right Click



end)

This step is for if you have animations Next we want to move to the ADS, a good way to do this is to store all of your keyframes in a module script and call them in the main script.

local animModule = require(game.ReplicatedStorage.Anim)

animModule.AdsIn() -- Function name for the animation

Now we want to change the camera position to the player's position + a small value

cam.CoordinateFrame = cam.CoordinateFrame*CFrame.new(0,0,5) --If you can see through walls, a Vector3 might be better

That was simple, Right?

Now if you have a scope GUI you want that to be visible.

script.gunGui.Scope.Visible = true

Now you can scope with Right Mouse!

But you're also stuck!

So now we need to return!

To do this we start with a buttonup function.

mouse.Button2Up:connect(function() --Right Release



end)

Next we return the camera to it's default state.

cam.CoordinateFrame = cam.CoordinateFrame*CFrame.new(0,0,-5)

And we make the scope GUI invisible.

script.gunGui.Scope.Visible = false

Then call the animation if you have any

local animModule = require(game.ReplicatedStorage.Anim)

animModule.AdsOut() -- Function name for the animation

And now you're done! The final result should look like this:

cam = game.Workspace.CurrentCamera
mouse = game.Players.LocalPlayer:GetMouse() 

mouse.Button2Down:connect(function()

    local animModule = require(game.ReplicatedStorage.Anim)

    animModule.AdsIn()

    cam.CoordinateFrame = cam.CoordinateFrame*CFrame.new(0,0,-5)

    script.gunGui.Scope.Visible = true

end)

mouse.Button2Up:connect(function()

    cam.CoordinateFrame = cam.CoordinateFrame*CFrame.new(0,0,-5)

    script.gunGui.Scope.Visible = false

    local animModule = require(game.ReplicatedStorage.Anim)

    animModule.AdsOut()

end)

Note: It might be simpler to define the animModule with cam and mouse, rather than in each function.

Use CameraMaxZoomDistance. Since it only affects one player at a time and you can use a regular script instead of a local one, It's great!

game:GetService("Players").PlayerAdded:connect(function(player)
    player.CameraMaxZoomDistance = 0.5 --0.5 is the minimum.
end)

If you would like to use it in a script:

--Hopperbin, can be regular script or local.
script.Parent.Selected:connect(function()
    local player = game:GetService("Players"):GetPlayerFromCharacter(script.Parent.Parent)
    if player then
        player.CameraMaxZoomDistance = 0.5 --If you change it to 0, it will just turn back to 0.5.
    end
end)

Hope it helps!
