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.
- int seed
The seed used by the random number generator. 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.
- float randf ( )
Generates pseudo-random float between ‘0.0’ and ‘1.0’, inclusive.
Generates pseudo-random float between
Generates normally(gaussian) distributed pseudo-random number, using Box-Muller transform with the specified
mean and a standard
- int randi ( )
Generates pseudo-random 32-bit unsigned integer between ‘0’ and ‘4294967295’, inclusive.
Generates pseudo-random 32-bit signed integer between
- void randomize ( )
Setups a time-based seed to generator.
