Please Help With Updating Pathfinding/Chase Script?

Ok So I am trying to update my chase script for my zombies from the deprecated and older system of GetPointCoordinates() to GetWaypoints(). Right now my script works but as you can see in the script I have to tell NPC's to jump and to be honest it is not the best pathfinding script. If anyone has any suggestions, a better NEW pathfinding script or can help me re-code this I would be very grateful for the help. Thanks in advance.

workspace:WaitForChild("Wave0")
local p=game:GetService("PathfindingService")

p.EmptyCutoff=0.024



function addz(v)
    spawn(function()
        v:WaitForChild("Humanoid").WalkSpeed=16
        local parts={}
        local target=v.Head
                v.Humanoid.Died:connect(function()wait(5)v:Destroy().Parent=workspace.Wave0 end)

        while wait()do
            if v.Humanoid.Health==0 then break end

            if target==v.Head or not target:IsDescendantOf(workspace)then
                local r={}
                for _,v in pairs(game.Players:GetPlayers())do
                    pcall(function()
                        r[#r+1]=v.Character.Head
                    end)
                end
                target=#r>0 and r[math.random(1,#r)]or target
            end
            for _,v in pairs(parts)do v:health(-20)end parts={}
