Help with understanding Random.new()

Help and Feedback Scripting Support
#1

I had a guy help me with my Region3 Script, it works, but I have a problem understanding some of the code, and I was wondering if you guys can explain it to me or something. There are a couple of new concepts I have not learned yet.

Here is the code, I cant remember who helped me, he did most of the heavy lifting.

Thank you for your time.

local Workspace = workspace
local Part1 = Workspace.Region3Folder.F
local Part2 = Workspace.Region3Folder.E
local RandomObject = Random.new()

local function RandomPoint(Part1, Part2, Axis) --Part1, Part2, Axis.
	return RandomObject:NextNumber(math.min(Part1.Position[Axis], Part2.Position[Axis]), math.max(Part1.Position[Axis], Part2.Position[Axis]))
end

local function SpawnRandomPart(Part1, Part2)
	local Part = workspace.Meteor:Clone()
	Part.Name = "MeteorDestroy"
	Part.Position = Vector3.new(RandomPoint(Part1, Part2, "X"),RandomPoint(Part1, Part2, "Y") ,RandomPoint(Part1, Part2, "Z"))
	--print(Part.Position)
	Part.Parent = Workspace
end

for i = 1, math.huge do
	wait(2)
	SpawnRandomPart(Part1, Part2)
end

Random.new() has the same algorithm as math.random, but It’s not global so it has not been touched by other scripts.

math.random() is global
Random.new() is not
