Raycast won't ignore table?

Goal To make a part that face the player using a ray, and using a table to collect all of the descendants of the player except for the HumanoidRootPart so the body parts in the table would be ignored by the ray.

Script

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local BodyParts = {}

for i,v in pairs(game.Players:GetChildren()) do
	for _,p in pairs(v.Character:GetDescendants()) do
		if not p.Name == "HumanoidRootPart" then
			BodyParts[p] = p
			table.insert(BodyParts, script.Parent)
		end
	end
end

local function PlayerTarget(A)
	RunService.Heartbeat:Connect(function()
		script.Parent.CFrame = CFrame.new(script.Parent.Position, A.Position)
		local PlayerRay = Ray.new(script.Parent.CFrame.p, (A.CFrame.p - script.Parent.CFrame.p).unit * 500)
		local HIT = game.Workspace:FindPartOnRayWithIgnoreList(PlayerRay ,BodyParts)
		print(HIT)
	end)
end

Problem

local HIT = game.Workspace:FindPartOnRayWithIgnoreList(PlayerRay ,BodyParts)

Everything in the script works correctly, except for this line. The ray does work, but it won't ignore the BodyParts table, if I change "FindPartOnRayWithIgnoreList" with "FindPartOnRay" it will state "Unable to cast value to Object" on the output pointing to the line above. Any idea how to fix this?

The problem is in this line:

if not p.Name == "HumanoidRootPart" then

It evaluates not p.Name and checks if that is equal to "HumanoidRootPart". Since p.Name is a string which evaluates to true, not p.Name would evaluate to false and it's essentially doing if false == "HumanoidRootPart".

Instead of using not thing == anotherThing, use the ~= (not equal to) operator instead, as such:

if p.Name ~= "HumanoidRootPart" then

Hope this helped.
