How to generate random numbers in Godot

Random numbers are very useful in games and generating them is usually a single line of code. In this tutorial, we will see how to generate random numbers in Godot and see the available functions.

I am using Godot 3.4.2 for this tutorial.

To generate a random number in Godot you need to initialize a variable of type RandomNumberGenerator as shown below

var rand=RandomNumberGenerator.new()

You can set the seed if you want but it’s completely optional. Seed can be set as shown below

rand.seed=1001023

You can also set a random seed based on time using

rand.randomize()

Once initialized you can generate random numbers using the following functions

Function	Properties
randf()	Generates a random float between 0 and 1
randf_range()	Generates a random float in the given range
randi()	Generates a random integer
randi_range()	Generates a random int in the given range.

Here is a sample script to generate random numbers in Godot

extends Node2D

var rand=RandomNumberGenerator.new()
func _ready():
	rand.randomize()
	print(rand.randf())
