# 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.
# Objective
Fixes#15223
## Solution
Adds an `enabled` flag to the `FpsOverlayConfig` resource with a system
that detects it's change, and adjusts the visibility of the overlay text
entity.
## Testing
I extended the `fps_overlay` example with the option to toggle the
overlay. Run with:
```
cargo run --features="bevy_dev_tools" --example fps_overlay
```
# Objective
- Currently the fps_overlay affects any other ui node spawned. This
should not happen
## Solution
- Use position absolute and a ZIndex of `i32::MAX - 32`
- I also modified the example a little bit to center it correctly. It
only worked previously because the overlay was pushing it down. I also
took the opportunity to simplify the text spawning code a little bit.
# Objective
- Part of #12351
- Add fps overlay
## Solution
- Create `FpsOverlayPlugin`
- Allow for configuration through resource `FpsOverlayConfig`
- Allow for configuration during runtime
