# Objective Fixes issue #12613 - the RNG used in examples is _deterministic_, but its implementation is not _portable_ across platforms. We want to switch to using a portable RNG that does not vary across platforms, to ensure certain examples play out the same way every time. ## Solution Replace all occurences of `rand::rngs::StdRng` with `rand_chacha::ChaCha8Rng`, as recommended in issue #12613 --- ## Changelog - Add `rand_chacha` as a new dependency (controversial?) - Replace all occurences of `rand::rngs::StdRng` with `rand_chacha::ChaCha8Rng` |

Stress tests
These examples are used to stress test Bevy's performance in various ways. These should be run with the "stress-test" profile to accurately represent performance in production, otherwise they will run in cargo's default "dev" profile which is very slow.
Example Command
cargo run --profile stress-test --example <EXAMPLE>
