In a previous post I’ve introduced the Gaussian distribution and how it is commonly found in the vast majority of natural phenomenon. It can be used to dramatically improve some aspect of your game, such as procedural terrain generation, enemy health and attack power, etc. Despite being so ubiquitous, very few gaming frameworks offer functions to generate numbers which follow such distribution. Unity developers, for instance, heavily rely on `Random.Range`

which generates uniformly distributed numbers (in blue). This post will show how to generate Gaussian distributed numbers (in red) in C#.

I’ll be explaining the Maths behind it, but there is no need to understand it to use the function correctly. You can download the `RandomGaussian`

Unity script here.
