Struct Random 

pub struct Random { /* private fields */ }

The game’s random number generator. See the module documentation.

Implementations

impl Random

pub fn new(seed: u32) -> Random

A generator seeded with seed, as the engine seeds one.

Original: Random::Random(unsigned int), Runtime 0x1800ca740.

pub fn from_parts(index: u32, state: [u32; 624]) -> Random

A generator restored from a save: its index, then its 624 state words.

pub fn index(&self) -> u32

The position of the next word in the state.

pub fn state(&self) -> &[u32; 624]

The 624 state words.

pub fn rand(&mut self) -> u32

The next number, any u32.

Original: Rand(), Runtime 0x1800ca800.

pub fn rand_below(&mut self, n: u32) -> u32

A number from 0 to n - 1. When n is 0, it returns 0 and draws nothing.

Original: Rand(unsigned int), Runtime 0x1800ca8b0.

pub fn rand_range(&mut self, lo: i32, hi: i32) -> i32

A number from lo to hi, both included.

Original: Rand(int, int), Runtime 0x1800ca5e0.

pub fn rand_tol(&mut self, t: i32) -> i32

A number from -t to t, both included.

Original: RandTol(int), Runtime 0x1800ca610.

pub fn rand_float(&mut self) -> f32

A float from 0 to 1, 1 not included: (float)u × 2⁻³².

Original: RandFloat(), Runtime 0x1800ca5b0.

pub fn rand_float_tol(&mut self) -> f32

A float from -1 to 1, -1 not included: 1 − (float)u × 2⁻³² × 2.

Original: RandFloatTol(), Runtime 0x1800ca870.
