# Objective Another step in the migration to required components: lights! Note that this does not include `EnvironmentMapLight` or reflection probes yet, because their API hasn't been fully chosen yet. ## Solution As per the [selected proposals](https://hackmd.io/@bevy/required_components/%2FLLnzwz9XTxiD7i2jiUXkJg): - Deprecate `PointLightBundle` in favor of the `PointLight` component - Deprecate `SpotLightBundle` in favor of the `PointLight` component - Deprecate `DirectionalLightBundle` in favor of the `DirectionalLight` component ## Testing I ran some examples with lights. --- ## Migration Guide `PointLightBundle`, `SpotLightBundle`, and `DirectionalLightBundle` have been deprecated. Use the `PointLight`, `SpotLight`, and `DirectionalLight` components instead. Adding them will now insert the other components required by them automatically.

//! 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.
