# js-tinymt
[](https://travis-ci.org/mizdra/js-tinymt)
[](https://badge.fury.io/js/%40mizdra%2Ftinymt)
The JavaScript implements of TinyMT for Pokémon RNG.
## :warning: Note :warning:
This library is not designed for common use, but for **Pokémon RNG**.
If you want to use for simulation and numerical analysis and so on,
**I recommend other library**.
## Installation
```bash
$ npm install @mizdra/tinymt -S
# or
$ yarn add @mizdra/tinymt
```
## Usage
```js
import * as assert from 'assert'
import { Tinymt32 } from '@mizdra/tinymt'
function u32 (num) {
return num >>> 0
}
const param: Tinymt32.Param = {
mat1: 0x8F7011EE,
mat2: 0xFC78FF1F,
tmat: 0x3793fdff,
}
const seed = 1
const status = [0xCCA24D8, 0x11BA5AD5, 0xF2DAD045, 0xD95DD7B2]
// Tinymt32.fromSeed(param, seed)
const rng1 = Tinymt32.fromSeed(param, seed)
assert(u32(rng1.gen()) === 2545341989)
assert(u32(rng1.gen()) === 981918433)
assert.deepEqual(
[...Array(2)].map((_) => u32(rng1.gen())),
[3715302833, 2387538352],
)
// Tinymt32.fromStatus(param, status)
const rng2 = Tinymt32.fromStatus(param, status)
rng2.nextState()
assert(u32(rng2.temper()) === 2545341989)
assert(u32(rng2.gen()) === 981918433)
assert(u32(rng2.temper()) === 981918433)
for (let i = 0; i < 2; i++) { rng2.nextState() }
assert.deepEqual(
rng1.status().map(u32),
rng2.status().map(u32),
)
```
