I'm making a 2-D running game where you play as a noob (btw I didn't turn the player in to a noob I just created a called dummy1 and he's a npc) so I need the camera to be locked but, this makes it really jittery so can you help me. (code down below\/)

01wait(0.3)
02local cam = workspace.CurrentCamera
03-- Move the camera to the location of the player's torso
04cam.CameraType = "Scriptable"
05--cam.FieldOfView = 3
06cam.CameraSubject = workspace.Dummy1.Torso
07--cam.CoordinateFrame = CFrame.new(workspace.Dummy1.Torso.Position,workspace.Dummy1.Torso.Position)
08-- Now move the camera off of the player's side 
09 
10-- Now orient the camera to look at the player
11 
12--game:GetService('Runservice').Renderstepped:connect(function()
13--  while true do
14--      cam.CoordinateFrame = game.Workspace.Dummy1.HumanoidRootPart.CFrame * CFrame.Angles(0,math.rad(100),0) * CFrame.new(0,0,25)
15    --end
16--end)
17 
18--local foo = false
19 
20game:GetService("RunService").RenderStepped:connect(function ()
21    cam.CoordinateFrame = game.Workspace.Dummy1.HumanoidRootPart.CFrame * CFrame.Angles(0,math.rad(100),0) * CFrame.new(0,0,25)
22end)``

I have made numerous 2-Dimensional games on ROBLOX and this is usually the script I use to set a 2-Dimensional environment for the player.

01function GetMass(object)
02    local mass = 0
03    if pcall(function() return object:GetMass() end) then
04        mass = object:GetMass()
05    end
06    for _,child in pairs(object:GetChildren()) do
07        mass = mass + GetMass(child)
08    end
09    return mass
10end
11 
12function onPlayerRespawned(newPlayer)
13    wait()
14    local torso = newPlayer.Character.Torso 
15    local bp = Instance.new("BodyPosition")
16    bp.Name = "TwoD"
17    bp.position = torso.Position
18    bp.P = 1000000
19    bp.D = 1000
20    bp.maxForce = Vector3.new(0, 0, 1000000)
21    bp.Parent = torso
22    local bf = Instance.new("BodyForce")
23    bf.force = Vector3.new(0, 100*GetMass(newPlayer.Character), 0)
24    bf.Parent = torso
25    newPlayer.Character.Humanoid.WalkSpeed = 24
26    script.LocalScript:Clone().Parent = torso.Parent
27    newPlayer.Character.DescendantAdded:connect(function()
28        bf.force = Vector3.new(0, 100*GetMass(newPlayer.Character), 0)
29    end)
30    newPlayer.Character.DescendantRemoving:connect(function()
31        bf.force = Vector3.new(0, 100*GetMass(newPlayer.Character), 0)
32    end)
33end
34 
35function onPlayerEntered(newPlayer)
36    if newPlayer.Character then
37        onPlayerRespawned(newPlayer)
38    end
39    newPlayer.Changed:connect(function (property)
40        if (property == "Character") and newPlayer.Character then
41            onPlayerRespawned(newPlayer)
42        end
43    end)
44end

46game.Players.PlayerAdded:connect(onPlayerEntered)

So, you can put this script in the Workspace. Then insert a LocalScript inside the script (yes, that is script-ception) and paste this into the LocalScript.

01lockCamera = true --set true if you want the player to move the camera on a vertical axis only and zoom in and out as much as they want, if you want the player to have a complete locked camera keep it as true
02    distance = 15 -- you can modify this to your liking
03    height = 5 -- you can modify this to your liking
04 
05local torso = script.Parent.Torso
06local center = Instance.new("Part")
07center.Name = script.Parent.Name .. " Center"
08center.Transparency = 1
09center.CanCollide = false
10center.Size = Vector3.new(1,1,1)
11center.Position = torso.Position
12center.CFrame = CFrame.new(Vector3.new(0,0,0),Vector3.new(0,0,-1))
13center.Parent = game.Workspace
14local bp = Instance.new("BodyPosition")
15bp.position = center.Position
16bp.maxForce = Vector3.new(1000000, 1000000, 1000000)
17bp.Parent = center
18local bg = Instance.new("BodyGyro")
19bg.maxTorque = Vector3.new(9e+005, 9e+005, 9e+005)
20bg.cframe = center.CFrame
21bg.Parent = center
22local cam = game.Workspace.CurrentCamera
23cam.CameraSubject = center
24cam.CameraType = Enum.CameraType.Attach
25 
26while torso.Parent do
27    wait()
28    center.BodyPosition.position = torso.Position
29    if lockCamera then
30        cam.CoordinateFrame = CFrame.new(Vector3.new(center.Position.x + distance,center.Position.y + height,center.Position.z))
31    end
32end
33 
34center:Remove()

Hope this helps!

Thank you but, dummy1 is in fact a npc so I don't think that this script could work (he's a npc so that it's simple to make him run not only that as abused to changing how the character looks ) gaberdell 71 — 9y

You could try setting the camera subject to the humanoid within the dummy model. That is how ROBLOX has the default camera subject set as.
