[Solved] how to continually update the players speed?

so im making this thing and i used hum.Running:Connect(function() but i noticed that it only fires if the speed changes im making a walking animation when the player is holding a gun i need it to sway and i need it so if the speed changes to 0 it stops i want it to all happen in the same loop is there any easy way of getting the speed?

EDIT: ok i did it this is what i did:

local speed = 0
hum.Running:Connect(function(speedyboi)
	speed = speedyboi
end
while wait() do
	--wat ever u want speed = the players speed
end
