# Objective Yet another PR for migrating stuff to required components. This time, cameras! ## Solution As per the [selected proposal](https://hackmd.io/tsYID4CGRiWxzsgawzxG_g#Combined-Proposal-1-Selected), deprecate `Camera2dBundle` and `Camera3dBundle` in favor of `Camera2d` and `Camera3d`. Adding a `Camera` without `Camera2d` or `Camera3d` now logs a warning, as suggested by Cart [on Discord](https://discord.com/channels/691052431525675048/1264881140007702558/1291506402832945273). I would personally like cameras to work a bit differently and be split into a few more components, to avoid some footguns and confusing semantics, but that is more controversial, and shouldn't block this core migration. ## Testing I ran a few 2D and 3D examples, and tried cameras with and without render graphs. --- ## Migration Guide `Camera2dBundle` and `Camera3dBundle` have been deprecated in favor of `Camera2d` and `Camera3d`. Inserting them will now also 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.
