Mob pathfinding like minecraft zombies?

The following code is little sniplets from my npc George, hes quite advanced. You can find him in person here:

https://www.roblox.com/library/331847610/Its-George

He can also (or could) drive vehicles and did i mention he can also get travel sick! :P

lol anyway the basics of his path finding is below. Your more than welcome to download him and disect his brain (he's kinda used to me doing it! lol)

Code:

local Self 	= script.Parent	 -- Base 
local ME 		= Self.Humanoid -- My Brain! :D
local Path 	= {}			-- a Table that holds the points of our path
local CurrentPoint = 1		-- Current point on our path to our destination

local function computePathtoV3(Target)
	local PFS = game:GetService("PathfindingService")
	local path = PFS:FindPathAsync(Self.HumanoidRootPart.CFrame.p,Target,1024)
	return path:GetWaypoints()
end


-- wrap this in your target finder function/bit!
--[[
kinda like 
local Target = workspace.TGazza
local TargetPos = Target.HumanoidRootPart.Position
]]
myPos = TargetPos
Path = computePathtoV3(myPos)


-- Main loop for traveling along the found path...
local atEnd = false
while true do
	if(#Path > 0 and AtEnd == false) then
		local Dist = (Self.HumanoidRootPart.Position - Path[CurrentPoint].Position).magnitude
		Self.Humanoid:MoveTo(Path[CurrentPoint].Position)
		if(Dist < 3) then
			CurrentPoint = CurrentPoint +1
		end
	end
	if(CurrentPoint >= #Path) then
		AtEnd = true
		--// do stuff!
	end
	wait()
end

Each time your npc gets to the end of a path you would clear the Path table and resetting the path index (CurrentPoint ) to 1

aka:

Path = {}
CutrrentPoint = 1

Hope this helps! :)
