Random Walking is a handy technique to have in your gamdev toolbelt and - despite the name - it is most useful for everything but actual walking. With random walking, we define the output of a process that can be described sequence of random steps. The main difference with a random sequence is that each new value will be statistically near the previous one. Imagine a gold price chart and assume that the current cost is 10€ for 1g of gold. We cannot guess what will be the price in one hour but we can be sure that it will be around 10€ per gram, maybe 9.5€, maybe 10.5€. What is certain, is that a sudden drop to 1€ per gram would be deeply unlikely.

In this article, we will talk briefly about random walking and its ability to simulate many real-world processes such as resources prices, temperature, floating objects position over time, and much more.
