Function Documentation

SP_EXPORT bool sp::math::Randomizer::randBool ( const u32 Probability )

Returns true if the specified probability occurs. This is equivalent to "randInt(Probability) == 0".

SP_EXPORT video::color sp::math::Randomizer::randColor ( bool RandAlpha )

Returns a random color. If 'RandAlpha' is false, the alpha channel is always 255.

SP_EXPORT f32 sp::math::Randomizer::randFloat	(	const f32	Min,
		const f32	Max
	)

Returns a floating point random value in the range [Min .. Max].

SP_EXPORT f32 sp::math::Randomizer::randFloat ( )

Returns a random value in the range [0.0 .. 1.0].

SP_EXPORT f32 sp::math::Randomizer::randFloat ( const f32 Max )

Returns a floating point random value in the range [0.0 .. Max].

SP_EXPORT s32 sp::math::Randomizer::randInt ( )

Returns a random value in the range [0 .. RAND_MAX].

SP_EXPORT s32 sp::math::Randomizer::randInt	(	const s32	Min,
		const s32	Max
	)

Returns a random value in the range [Min .. Max]. These values can also be negative.

SP_EXPORT s32 sp::math::Randomizer::randInt ( const s32 Max )

Returns a random value in the range [0 .. Max]. This value can also be negative.

SP_EXPORT dim::vector3df sp::math::Randomizer::randVector ( )

Returns a random direction vector. This vector is always normalized.

SP_EXPORT void sp::math::Randomizer::seedRandom ( bool isTimeBase = true )

Seeds a random to have always other random values when the program starts.

Parameters:

isTimeBase,:

Specifies whether the current time shall be used as the base for further random value generations.
