A class for generating pseudo-random numbers.
RandomNumberGenerator is a class for generating pseudo-random numbers. It currently uses [url=http://www.pcg-random.org/]PCG32[/url]. [b]Note:[/b] The underlying algorithm is an implementation detail. As a result, it should not be depended upon for reproducible random streams across Godot versions. To generate a random float number (within a given range) based on a time-dependant seed: [codeblock] var rng = RandomNumberGenerator.new() func _ready(): rng.randomize() var my_random_number = rng.randf_range(-10.0, 10.0) [/codeblock]

Generates a pseudo-random float between [code]0.0[/code] and [code]1.0[/code] (inclusive).
Generates a pseudo-random float between [code]from[/code] and [code]to[/code] (inclusive).
Generates a [url=https://en.wikipedia.org/wiki/Normal_distribution]normally-distributed[/url] pseudo-random number, using Box-Muller transform with the specified [code]mean[/code] and a standard [code]deviation[/code]. This is also called Gaussian distribution.
Generates a pseudo-random 32-bit unsigned integer between [code]0[/code] and [code]4294967295[/code] (inclusive).
Generates a 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. [b]Note:[/b] The default value of this property is pseudo-random, and changes when calling [method randomize]. The [code]0[/code] value documented here is a placeholder, and not the actual default seed.
