Function documentation

sead::Random::Random(u32 seed_x, u32 seed_y, u32 seed_z, u32 seed_w)

void sead::Random::init(u32 seed_x, u32 seed_y, u32 seed_z, u32 seed_w)

s32 sead::Random::getS32Range(s32 a, s32 b)

Generate a random s32 in [a .. b). Note that this does not provide a uniform distribution.

s64 sead::Random::getS64Range(s64 a, s64 b)

Generate a random s64 in [a .. b). Note that this does not provide a uniform distribution.
