Hello, how do i make it so in this script at random points in time it stops animating the part for a random amount of time?
Script:

local seed = 3
local p = script.Parent.Humanoid

function r()
	seed = seed + 3
	math.randomseed(tick() + seed)
end

function go(part)
	p:MoveTo(part.Position)
	p.MoveToFinished:Wait()
end

local locsv = game.Workspace:WaitForChild("WanderPoints")
local locs = locsv:GetChildren()
local loc = locsv:WaitForChild("Start")
local prev = loc

while true do
	local locs = locsv:GetChildren()
	go(loc)
	local tab = {}
	for i = 1,#locs,1 do
		local sub = locs[i]
		if (loc.Position-sub.Position).Magnitude <= 32 and sub ~= loc and sub ~= prev then
			table.insert(tab,#tab+1,sub)
		end
	end
	--We now have a table of possible locations.
	r()
	local newVar = math.random(1,#tab)
	prev = loc
	loc = tab[newVar]
	go(loc)
	wait()
end
