Free Cam

Sup,
I am currently looking for a good Free Cam Script for Garrys Mod. I have tested several scripts but most of them have not worked really well. One of the scripts worked but you couldn't unload it.

And yes everything was translated.

freecamAngles = Angle()
freecamAngles2 = Angle()
freecamPos = Vector()
freecamEnabled = false
freecamSpeed = 3
keyPressed = false

hook.Add("CreateMove", "lock_movement", function(ucmd)
if(freecamEnabled) then
ucmd:SetSideMove(0)
ucmd:SetForwardMove(0)
ucmd:SetViewAngles(freecamAngles2)
ucmd:RemoveKey(IN_JUMP)
ucmd:RemoveKey(IN_DUCK)

freecamAngles = (freecamAngles + Angle(ucmd:GetMouseY() * .023, ucmd:GetMouseX() * -.023, 0));
freecamAngles.p, freecamAngles.y, freecamAngles.x = math.Clamp(freecamAngles.p, -89, 89), math.NormalizeAngle(freecamAngles.y), math.NormalizeAngle(freecamAngles.x);

local curFreecamSpeed = freecamSpeed
if(input.IsKeyDown(KEY_LSHIFT)) then
curFreecamSpeed = freecamSpeed * 2
end

if(input.IsKeyDown(KEY_W)) then
freecamPos = freecamPos + (freecamAngles:Forward() * curFreecamSpeed)
end
if(input.IsKeyDown(KEY_S)) then
freecamPos = freecamPos - (freecamAngles:Forward() * curFreecamSpeed)
end
if(input.IsKeyDown(KEY_A)) then
freecamPos = freecamPos - (freecamAngles:Right() * curFreecamSpeed)
end
if(input.IsKeyDown(KEY_D)) then
freecamPos = freecamPos + (freecamAngles:Right() * curFreecamSpeed)
end
if(input.IsKeyDown(KEY_SPACE)) then
freecamPos = freecamPos + Vector(0,0,curFreecamSpeed)
end
if(input.IsKeyDown(KEY_LCONTROL)) then
freecamPos = freecamPos - Vector(0,0,curFreecamSpeed)
end
end
end)

hook.Add("Tick", "checkKeybind", function()
if(input.IsKeyDown(KEY_LALT)) then
if(!keyPressed) then
print("enable freecam")
freecamEnabled = !freecamEnabled
freecamAngles = LocalPlayer():EyeAngles()
freecamAngles2 = LocalPlayer():EyeAngles()
freecamPos = LocalPlayer():EyePos()
keyPressed = true
end
else
keyPressed = false
end
end)

hook.Add("CalcView", "freeCam", function(ply, pos, angles, fov)
local view = {}
if(freecamEnabled) then
view = {
origin = freecamPos,
angles = freecamAngles,
fov = fov,
drawviewer = true
}
else
view = {
origin = pos,
angles = angles,
fov = fov,
drawviewer = false
}
end

return view
end)
