 # Simple math.noise world generation [Updated]

Math.noise is easy way to make world generation, draws curved lines and repeats by map size and coordinates like this:

Let’s start:
Make script in Workspace

``````math.noise(x, y, z)
``````

Ok we have XYZ coordinates, now we need Seed number.

``````local seed = math.random(1,999999) --Random seed that helps draw of Curved Lines.
math.noise(x, y, seed)
``````

Now we have Seed number, but we need size of map and XY coordinates, map size.

``````local seed = math.random(1,999999) --Random seed that helps draw of Curved Lines.
local map_size = 50 --Repeats Curve Lines by XY coords.
for x = 0, map_size do
for y = 0, map_size do
local h = math.noise(x, y, seed)
end
end
``````

Good, now we need Height, and terrain Smooth.

``````local smooth = 50 --How smooth will be Curved Lines.
local seed = math.random(1,999999) --Random seed that helps draw of Curved Lines.
local height = 50 --Max height of Curved Lines.
local map_size = 50 --Repeats Curve Lines by XY coords.
for x = 0, map_size do
for y = 0, map_size do
local h = math.noise(x / smooth, y / smooth, seed) * height
end
end
``````

And to finish this world generation we will make terrain parts and part size.

``````local size = 2 --Size of part.
local smooth = 50 --How smooth will be Curved Lines.
local seed = math.random(1,999999) --Random seed that helps draw of Curved Lines.
local height = 50 --Max height of Curved Lines.
local map_size = 50 --Repeats Curve Lines by XY coords.
for x = 0, map_size do
for y = 0, map_size do
local h = math.noise(x / smooth, y / smooth, seed) * height
local p = Instance.new("Part")
p.Position = Vector3.new(x * size, h, y * size)
p.Anchored = true
p.Size = Vector3.new(size, size, size)
p.Parent = game.Workspace
end
end
``````

And start the place, WOW we made it:

Can you explain a bit more and tell where to put the script? It will be very confusing for new devs trying to learn world generation. Thanks!

Can you actually explain what each code does so that beginner devs can understand it more? This feels more a resource than a tutorial.

If i’m correct, because it is relating to map, it should so in ServerScriptService. If it was local everyone would have a different map.

I think script can be located in Workspace and ServerScriptService.

Cant it be in workspace too?
Although can be in SSS (serverscriptservice)

This is so cool, I attempted this and the results were amazing. Reminds me of the old Roblox Terrain.
Here’s a YouTube how-to link for anyone who does not know what I am talking about.

Yes, the script can be located in Workspace or ServerScriptService, and Workspace is not local, it is a server like ServerScriptService, so you can create a script in Workspace or ServerScriptService.
