A class for generating pseudo-random numbers.
RandomNumberGenerator is a class for generating pseudo-random numbers. It currently uses PCG32. The underlying algorithm is an implementation detail. As a result, it should not be depended upon for reproducible random streams across Godot versions.
Generates pseudo-random float between '0.0' and '1.0', inclusive.
Generates pseudo-random float between [code]from[/code] and [code]to[/code], inclusive.
Generates normally(gaussian) distributed pseudo-random number, using Box-Muller transform with the specified [code]mean[/code] and a standard [code]deviation[/code].
Generates pseudo-random 32-bit unsigned integer between '0' and '4294967295', inclusive.
Generates pseudo-random 32-bit signed integer between [code]from[/code] and [code]to[/code] (inclusive).
Setups a time-based seed to generator.
- The seed used by the random number generator. A given seed will give a reproducible sequence of pseudo-random numbers. [b]Note:[/b] The RNG does not have an avalanche effect, and can output similar random streams given similar seeds. Consider using a hash function to improve your seed quality if they're sourced externally.
