Why my value is true now, but it still pass while Value == false do???

If you set Fighting to script.Parent.FoundPlayer.Value, you set it to the literal value at that present time, rather than setting it to "Whatever the value is".

local Noob = script.Parent
local Part = workspace.Part
local Part2 = workspace.Part1
local Fighting = script.Parent.FoundPlayer -- Reference the BooleanValue instance, rather than the value
----------------------------
while Fighting.Value == false do -- Reference the value from the instance
    print("Still...")
    if Fighting.Value == false then -- Reference the value from the instance
        Noob.Humanoid:MoveTo(Part.Position)
        Noob.Humanoid.MoveToFinished:wait()
    end
    if Fighting.Value == false then -- Reference the value from the instance
        Noob.Humanoid:MoveTo(Part2.Position)
        Noob.Humanoid.MoveToFinished:wait()
    end
end
