Function Documentation

poissonDiscDistribution()

XY_EXPORT_API std::vector<sf::Vector2f> xy::Util::Random::poissonDiscDistribution	(	const sf::FloatRect &	area,
		float	minDist,
		std::size_t	maxPoints,
		std::mt19937 &	engine = rndEngine
	)

Returns a poission disc sampled distribution of points within a given area.

Parameters

area	sf::FloatRect within which the points are distributed
minDist	minimum distance between points
maxPoints	maximum number of points to try generating
engine	Seeded random engine to use. Defaults to (non-threadsafe) instance seeded with current time

value() [1/2]

static float xy::Util::Random::value ( float  begin, float  end, std::mt19937 &  engine = rndEngine  )

inlinestatic

Returns a pseudo random floating point value.

Parameters

begin	Minimum value
end	Maximum value
engine	Seeded random engine to use. Defaults to (non-threadsafe) instance seeded with current time

value() [2/2]

static int xy::Util::Random::value ( int  begin, int  end, std::mt19937 &  engine = rndEngine  )

inlinestatic

Returns a pseudo random integer value.

Parameters

begin	Minimum value
end	Maximum value
engine	Seeded random engine to use. Defaults to (non-threadsafe) instance seeded with current time
