Generates a pseudo-random float between 0.0 and 1.0 (inclusive).
Generates a pseudo-random float between from and to (inclusive).
Generates a url=https://en.wikipedia.org/wiki/Normal_distributionnormally-distributed/url pseudo-random number, using Box-Muller transform with the specified mean and a standard deviation. This is also called Gaussian distribution.
Generates a pseudo-random 32-bit unsigned integer between 0 and 4294967295 (inclusive).
Generates a pseudo-random 32-bit signed integer between from and to (inclusive).
Setups a time-based seed to generator.
Initializes the random number generator state based on the given seed value. A given seed will give a reproducible sequence of pseudo-random numbers. Note: 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. Note: Setting this property produces a side effect of changing the internal state, so make sure to initialize the seed before modifying the state:
The current state of the random number generator. Save and restore this property to restore the generator to a previous state:
Construct a new instance of RandomNumberGenerator. Note: use memnew!RandomNumberGenerator instead.
var rng = RandomNumberGenerator.new() func _ready(): rng.randomize() var my_random_number = rng.randf_range(-10.0, 10.0)
Note: The default values of seed and state properties are pseudo-random, and changes when calling randomize. The 0 value documented here is a placeholder, and not the actual default seed.
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. Note: 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:
