To achieve this, you can use random *noise* functions. Noise functions are
especially popular in procedural generation to generate realistic-looking
terrain. Godot provides :ref:`class_opensimplexnoise` for this, which supports
terrain. Godot provides :ref:`class_fastnoiselite` for this, which supports
1D, 2D, 3D, and 4D noise. Here's an example with 1D noise:
.. tabs::
.. code-tab:: gdscript GDScript
var _noise = OpenSimplexNoise.new()
var _noise = FastNoiseLite.new()
func _ready():
randomize()
# Configure the OpenSimplexNoise instance.
# Configure the FastNoiseLite instance.
_noise.seed = randi()
_noise.octaves = 4
_noise.period = 20.0
_noise.persistence = 0.8
_noise.fractal_octaves = 4
_noise.frequency = 1.0 / 20.0
