Procedural Content Generation for Unity Game Development

Random versus pseudo random numbers

The most important distinction to make is that PRNs are not random numbers. A truly random event would be something like a die roll. We could write some sort of physics simulation to simulate a die roll to achieve a random number. We could also take the static from a TV screen and plot it on an XY plane and take a single point to represent a random number. However, PRNs are preferred in game programming because they are easier to generate. The preceding examples would take too much processing power as they are a fairly complex idea. But a PRN generator is an equation that calculates a string of numbers. This also produces an added benefit of being able to find our way back to a certain generated result.
