View Bobbing Script stopped working with certain scripts?

I need help, I am using this view bobbing script and I need help fixing it. I am making a short horror/puzzle game and I need some help with some of the scripts. . .

View Bobbing Script

repeat wait() until game.Players.LocalPlayer.Character

camera = game.Workspace.CurrentCamera
character = game.Players.LocalPlayer.Character

Z = 0

damping = character.Humanoid.WalkSpeed / 2

PI = 3.1415926

tick = PI / 2

running = false
strafing = false

character.Humanoid.Strafing:connect(function(bool)
    strafing = bool
end)

character.Humanoid.Jumping:connect(function()
    running = false
end)

character.Humanoid.Swimming:connect(function()
    running = false
end)

character.Humanoid.Running:connect(function(speed)
    if speed > 0.1 then
        running = true
    else
        running = false
    end
end)

function mix(par1, par2, factor)
    return par2 + (par1 - par2) * factor
end

while true do
    game:GetService("RunService").RenderStepped:wait()

    fps = (camera.CoordinateFrame.p - character.Head.Position).Magnitude

    if fps < 0.52 then
        Z = 1
    else
        Z = 0
    end

    if running == true and strafing == false then
        tick = tick + character.Humanoid.WalkSpeed / 92 --Calculate Bobbing speed.
    else
        if tick > 0 and tick < PI / 2 then
            tick = mix(tick, PI / 2, 0.9)
        end
        if tick > PI / 2 and tick < PI then
            tick = mix(tick, PI / 2, 0.9)
        end
        if tick > PI and tick < PI * 1.5 then
            tick = mix(tick, PI * 1.5, 0.9)
        end
        if tick > PI * 1.5 and tick < PI * 2 then
            tick = mix(tick, PI * 1.5, 0.9)
        end
    end

    if tick >= PI * 2 then
        tick = 0
    end 

    camera.CoordinateFrame = camera.CoordinateFrame * 
        CFrame.new(math.cos(tick) / damping, math.sin(tick * 2) / (damping * 2), Z) * 
        CFrame.Angles(0, 0, math.sin(tick - PI * 1.5) / (damping * 20)) --Set camera CFrame
end

It sadly doesn't work with these 2 scripts. . .

First Person Seat thing...

while wait(1) do
self = script.Parent
c = workspace.CurrentCamera

player = game.Players.LocalPlayer
char = player.Character or player.CharacterAdded:wait()
humanoid = char:WaitForChild("Humanoid")
function ok()
humanoid.CameraOffset = Vector3.new(0,0,-1.2)
end
function ok2()
humanoid.CameraOffset = Vector3.new(0,-1,-1.2)
end
function ok3()
humanoid.CameraOffset = Vector3.new(0,-3,-1.2)
end

-- Apply some properties

player.CameraMaxZoomDistance = 8
if humanoid.CameraOffset == Vector3.new(0,0,0) then
ok()
elseif humanoid.CameraOffset == Vector3.new(0,0,-1.2) then
ok()
elseif
humanoid.CameraOffset == Vector3.new(0,-1,-1.2) then
ok2()
elseif
humanoid.CameraOffset == Vector3.new(0,-3,-1.2) then
ok3()
end


function lock(part)
    if part and part:IsA("BasePart") then
        part.LocalTransparencyModifier = part.Transparency
        part.Changed:connect(function (property)
            part.LocalTransparencyModifier = part.Transparency
        end)
    end
end

for _,v in pairs(char:GetChildren()) do
    lock(v)
end

char.ChildAdded:connect(lock)

c.Changed:connect(function (property)
    if property == "CameraSubject" then
        if c.CameraSubject and c.CameraSubject:IsA("VehicleSeat") and humanoid then
            -- Vehicle seats try to change the camera subject to the seat itself. This isn't what we wan't really.
            c.CameraSubject = humanoid;
        end
    end
end)
end

and

First Person script (with crosshair and shows body, with smooth sensitivity).

I am thinking that one of the scripts are not compatible with the View Bobbing. . .

Any help / adivce (adivce for to become a better scripter) Plz?
