The RNG() constructor initializes a new instance of the pseudorandom number generator, seeded using the current time and date.
Usage
rng_object = new RNG();
API Information
Description
new RNG() initializes a new instance of the built-in pseudorandom number generator, seeded based on the current time and date. Unlike Math.random() which uses a very basic linear generator, Sphere uses the xoroshiro128+ algorithm, providing games with a very high-quality source of pseudorandom numbers.
To control the initial state of the generator, use RNG.fromSeed() or RNG.fromState().
