How do I stop following?

local player = game.Players.LocalPlayer
repeat wait() until player.Character
local mouse = player:GetMouse()
local seconds = 10 -- Put how long you want it to happen here

for i=1,seconds*100 do true do
wait(0.01)
if mouse.Hit then
player.Character.Humanoid.WalkToPoint = mouse.Hit.p
end
player.Character.Humanoid.WalkToPoint = player.Character.Humanoid.Torso.Position
end

local player = game.Players.LocalPlayer
repeat wait() until player.Character
local mouse = player:GetMouse()
local breaker = Instance.new("Part")
game:GetService("Debris"):AddItem(breaker,10)
while true do
wait()
if mouse.Hit  and breaker ~= nil then
player.Character.Humanoid.WalkToPoint = mouse.Hit.p
end
if breaker == nil then
break
end
end
