//! Hot reloading allows you to modify assets files to be immediately reloaded while your game is
//! running. This lets you immediately see the results of your changes without restarting the game.
//! This example illustrates hot reloading mesh changes.
//!
//! Note that hot asset reloading requires the [`AssetWatcher`](bevy::asset::io::AssetWatcher) to be enabled
//! for your current platform. For desktop platforms, enable the `file_watcher` cargo feature.
