Declaração

class Astra.RandomStream

Deterministic, per-owner random stream. State is explicitly capturable for replay/save. PCG-XSH-RR 32; Godot 4.5 RandomNumberGenerator is the capability reference. Algorithm/version belongs to Astra and is not sequence-compatible with Godot or Unity.

AlgorithmVersion

public const uint AlgorithmVersion = 1

.ctor

public RandomStream(ulong seed, ulong stream = 0)

Parâmetro	Tipo	Contrato
seed	ulong
stream	ulong	· Opcional: 0

Capture

public Astra.RandomStream.Snapshot Capture()

Gaussian

public float Gaussian(float mean = 0, float standardDeviation = 1)

Normal distribution using Box-Muller; zero deviation returns the mean.

Parâmetro	Tipo	Contrato
mean	float	· Opcional: 0
standardDeviation	float	· Opcional: 1

InsideUnitCircle

public System.Numerics.Vector2 InsideUnitCircle()

InsideUnitSphere

public System.Numerics.Vector3 InsideUnitSphere()

Uniform volume distribution, not a uniform radius.

NextUInt

public uint NextUInt()

OnUnitSphere

public System.Numerics.Vector3 OnUnitSphere()

Uniform direction on the unit sphere (no rejection loop).

Range

public int Range(int minimumInclusive, int maximumExclusive)

Uniform integer range [minimumInclusive, maximumExclusive), without modulo bias.

Parâmetro	Tipo	Contrato
minimumInclusive	int
maximumExclusive	int

Range

public float Range(float minimumInclusive, float maximumExclusive)

Finite float range [minimumInclusive, maximumExclusive). Equal endpoints return the endpoint.

Parâmetro	Tipo	Contrato
minimumInclusive	float
maximumExclusive	float

Restore

public void Restore(Astra.RandomStream.Snapshot snapshot)

Parâmetro	Tipo	Contrato
snapshot	Astra.RandomStream.Snapshot

Shuffle

public void Shuffle<T>(System.Span<T> values)

Fisher-Yates shuffle, unbiased bounded indices.

Parâmetro	Tipo	Contrato
values	System.Span<T>

Value

public float Value { get; }

Uniform [0,1), using 24 random bits exactly representable by float.
