:move function doesn't seem to work ?

What I want to do is to have a part which forces the player to go in a certain direction once touched and the player continues to move in that direction regardless of player input. For some reason :move function doesn't respond.

function directionlock(object)
    if object.Parent:FindFirstChild("Humanoid") then
        local h = object.Parent:FindFirstChild("Humanoid")
        h:Move(Vector3.new(0, 1, 0), true)
    end
end


script.Parent.Touched:connect(directionlock)
