This is useful for things such as roguelite run seeds, where you want to ensure results are exactly the same regardless of what hardware a player has.

Features

• next() method can be used to return a random 32 bit integer
• gaussian(mean, stddev) method can be used to instead return a random number along a gaussian normal curve
  • Because of the limitations of working with integers, this is not perfect, see the notes at the bottom.
• Written in C++ as a GDExtension addon
• Can be accessed by GDScript, C#, and any language Godot supports

Limitations of Gaussian Method

Only integer math is used to ensure deterministic outcomes across all platforms. As a result, values are rounded towards the mean. This means that if you provide a low standard deviation, the real stddev of the generated numbers will be smaller (e.g. given stddev = 2, results will really have a stddev of ~1.6). A workaround for this is to multiply all of your numbers by some factor of 10, because the larger the numbers are, the less significant this rounding is.
