+title: Random numbers
+brief: This example shows how to generate pseudo-random numbers in Defold using built-in math API.
+author: Defold Foundation
+scripts: random_numbers.script
+thumbnail: thumbnail.png
+---
+
+In this example you'll learn how to generate pseudo-random numbers in Defold using built-in math API.
+
+In the example there is only a game object containing:
+- *Label* component where we show the text information
+- *Script* component where we generate random numbers
+
+![collection](collection.png)
+
+Script sets the built-in random generator with a value of os.time() - which should be different every time you run it.
+Then produces 3 random numbers using math.random().
+
+For more details refer to Defold API: [https://defold.com/ref/stable/math-lua/#math.random:m-n](https://defold.com/ref/stable/math-lua/#math.random:m-n)

+1. First, set the randomseed. It can be specific, if you always want to generate same numbers,
+	otherwise you can utilise e.g. os.time, like in the example to make it different each time.
+2. math.random() with no arguments - generates a random floating point number between 0-1.
+3. math.random(X) with one argument - generates an integer between 1 - X.
+4. math.random(X, Y) with two arguments - generates an integer between X - Y.
