Function active

active(): Random.Generator
The generator the free functions (int, float, chance, ...) draw from.

This is the handle a SimulationRuntime needs to share the ambient stream: pass the returned object as the runtime's random and both sides draw from (and snapshot) one sequence, so a journal replay reproduces scene draws.

Returns Random.Generator
Example
```
import { Random } from '@datamoc/mwg/core';

Random.push(12345);
const shared = Random.active();
const roll = shared.int(20);
Random.pop();
```
