Multiple Raycasts from single point to each player on server

Help and Feedback Scripting Support
#1

Since nobody answered on Port zombie that made out of parts into proper r6 zombie character , I started making my own zombie ai, which will work close to https://create.roblox.com/marketplace/asset/201169102/Realistic-Zombie-AI but with proper limbs.
And so i ran into a problem that i dont know how to cast ray from single zombie to all players to later check closest player that is being seen by zombie.

#2

loop through all players and make the following ray

local ray = Ray.new(zombieroot.Position,
(playerroot.Position-zombieroot.Position).Unit*1000)

#4

the problem is i have no idea how to loop raycast to each player, and not skipping anybody, read carefully before actually answering please

#5

try this, might not work cause i wrote it on mobile :0


-- services
local players = game:GetService("Players")

-- variables
local zombie = script.Parent --????
local zroot = zombie:WaitForChild("HumanoidRootPart")

-- raycasting to all players
while task.wait() do
	for _, player in pairs(players:GetPlayers()) do
		local character = player.Character
		local root = character:FindFirstChild("HumanoidRootPart")
		
		if character and root then
			local ray = Ray.new(
			   zroot.Position,
			   (root.Position-zroot.Position)
			)
			local ignore = {zombie}
			local hit = workspace:FindPartOnRayWithIgnoreList(ray,ignore,false,true)
		end
	end
end
