Making a different type of rig with a humanoid move to closest player help

Help and Feedback Scripting Support
#1

This is the ‘different’ type of rig, it has a humanoid, primary part and everything is grouped in a model.
It can move if i set the MoveToPart manually but when i try it with a script it kinda breaks.

heres the script:

local SearchDistance = 	100000000

local WanderX, WanderZ = 30, 30

function getHumanoid(model)
   for _, v in pairs(model:GetChildren())do
   	if v:IsA'Humanoid' then
   		return v
   	end
   end
end


local Bot = script.Parent
local human = Bot:WaitForChild("Humanoid")
local hroot = Bot:WaitForChild("HumanoidRootPart")
local zspeed = hroot.Velocity.magnitude
local head = Bot.Head
local vars = script.vars

local pfs = game:GetService("PathfindingService")
local players = game:GetService('Players')

can someone help me making it work?
