GetSpeed() not working?

[G3bE]

Does it send 'nil' values or the actual number 0?

In the code above it's sending me the number 0, but in this code (yes, it is an anti cheat and I know that somebody else is doing this already)

function speedCheck(Player) -- called in OnPlayerMoving
  -- Horizontal speed check(doesn't include swimming)
 speed = Player:GetSpeedX() + Player:GetSpeedZ()
 -- if the player is sprinting
 if Player:IsSprinting() ~= nil then
   -- if he is faster than the max sprinting speed
   if speed > Player:GetSprintingMaxSpeed() then
     -- stop his movement
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 -- if the player is flying
 elseif Player:IsFlying() ~= nil then
   -- if he is faster than the max flying speed
   if speed > Player:GetFlyingMaxSpeed() then
     -- stop his movement
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 -- if the player is not sprinting and not flying he is walking normally
 else
   -- if he is faster than the max normal speed
   if speed > Player:GetNormalMaxSpeed() then
     -- stop his movement
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 end-- Horizontal speed check(doesn't includes swimming)
 speed = Player:GetSpeedX() + Player:GetSpeedY()
 -- if the player is sprinting
 if Player:IsSprinting() then
   -- if he is faster than the max sprinting speed
   if speed > Player:GetSprintingMaxSpeed() then
     -- stop his movement
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 -- if the player is flying
 elseif Player:IsFlying()  then
   -- if he is faster than the max flying speed
   if speed > Player:GetFlyingMaxSpeed() then
     -- stop his movement
     return true
   elseif Player:CanFly() == false then
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 -- if the player is not sprinting and not flying he is walking normally
 else
   -- if he is faster than the max normal speed
   if speed > Player:GetNormalMaxSpeed() then
     -- stop his movement
     return true
   -- if not
   else
     -- let the player move
     return false
   end
 end
end

it is sending me this error:

Code:

Warning: [23:03:44] LUA: Plugins/RAW_ac/checks/movement.lua:5: attempt to call method 'GetSpeedX' (a nil value)
Warning: [23:03:44] Stack trace:

Warning: [23:03:44] Error in <attached> calling function <callback>()

and the same comes for IsSprinting() if I set speed to 1 manually.
Hope that this helps.
