# Objective
Allow `Gizmos` to work in `FixedUpdate` without any changes needed. This
changes `Gizmos` from being a purely immediate mode api, but allows the
user to use it as if it were an immediate mode API regardless of
schedule context.
Also allows for extending by other custom schedules by adding their own
`GizmoStorage<Clear>` and the requisite systems:
- `propagate_gizmos::<Clear>` before `update_gizmo_meshes`
- `stash_default_gizmos` when starting a clear context
- `pop_default_gizmos` when ending a clear context
- `collect_default_gizmos` when grabbing the requested gizmos
- `clear_gizmos` for clearing the context's gizmos
## Solution
Adds a generic to `Gizmos` that defaults to `Update` (the current way
gizmos works). When entering a new clear context the default `Gizmos`
gets swapped out for that context's duration so the context can collect
the gizmos requested.
Prior work: https://github.com/bevyengine/bevy/pull/9153
## To do
- [x] `FixedUpdate` should probably get its own First, Pre, Update,
Post, Last system sets for this. Otherwise users will need to make sure
to order their systems before `clear_gizmos`. This could alternatively
be fixed by moving the setup of this to `bevy_time::fixed`?
PR to fix this issue: https://github.com/bevyengine/bevy/pull/10977
- [x] use mem::take internally for the swaps?
- [x] Better name for the `Context` generic on gizmos? `Clear`?
---
## Changelog
- Gizmos drawn in `FixedMain` now last until the next `FixedMain`
iteration runs.
# Objective
- Adds 3d grids, suggestion of #9400
## Solution
- Added 3d grids (grids spanning all three dimensions, not flat grids)
to bevy_gizmos
---
## Changelog
- `gizmos.grid(...)` and `gizmos.grid_2d(...)` now return a
`GridBuilder2d`.
- Added `gizmos.grid_3d(...)` which returns a `GridBuilder3d`.
- The difference between them is basically only that `GridBuilder3d`
exposes some methods for configuring the z axis while the 2d version
doesn't.
- Allowed for drawing the outer edges along a specific axis by calling
`.outer_edges_x()`, etc. on the builder.
## Additional information
Please note that I have not added the 3d grid to any example as not to
clutter them.
Here is an image of what the 3d grid looks like:

# Objective
- As part of the migration process we need to a) see the end effect of
the migration on user ergonomics b) check for serious perf regressions
c) actually migrate the code
- To accomplish this, I'm going to attempt to migrate all of the
remaining user-facing usages of `LegacyColor` in one PR, being careful
to keep a clean commit history.
- Fixes#12056.
## Solution
I've chosen to use the polymorphic `Color` type as our standard
user-facing API.
- [x] Migrate `bevy_gizmos`.
- [x] Take `impl Into<Color>` in all `bevy_gizmos` APIs
- [x] Migrate sprites
- [x] Migrate UI
- [x] Migrate `ColorMaterial`
- [x] Migrate `MaterialMesh2D`
- [x] Migrate fog
- [x] Migrate lights
- [x] Migrate StandardMaterial
- [x] Migrate wireframes
- [x] Migrate clear color
- [x] Migrate text
- [x] Migrate gltf loader
- [x] Register color types for reflection
- [x] Remove `LegacyColor`
- [x] Make sure CI passes
Incidental improvements to ease migration:
- added `Color::srgba_u8`, `Color::srgba_from_array` and friends
- added `set_alpha`, `is_fully_transparent` and `is_fully_opaque` to the
`Alpha` trait
- add and immediately deprecate (lol) `Color::rgb` and friends in favor
of more explicit and consistent `Color::srgb`
- standardized on white and black for most example text colors
- added vector field traits to `LinearRgba`: ~~`Add`, `Sub`,
`AddAssign`, `SubAssign`,~~ `Mul<f32>` and `Div<f32>`. Multiplications
and divisions do not scale alpha. `Add` and `Sub` have been cut from
this PR.
- added `LinearRgba` and `Srgba` `RED/GREEN/BLUE`
- added `LinearRgba_to_f32_array` and `LinearRgba::to_u32`
## Migration Guide
Bevy's color types have changed! Wherever you used a
`bevy::render::Color`, a `bevy::color::Color` is used instead.
These are quite similar! Both are enums storing a color in a specific
color space (or to be more precise, using a specific color model).
However, each of the different color models now has its own type.
TODO...
- `Color::rgba`, `Color::rgb`, `Color::rbga_u8`, `Color::rgb_u8`,
`Color::rgb_from_array` are now `Color::srgba`, `Color::srgb`,
`Color::srgba_u8`, `Color::srgb_u8` and `Color::srgb_from_array`.
- `Color::set_a` and `Color::a` is now `Color::set_alpha` and
`Color::alpha`. These are part of the `Alpha` trait in `bevy_color`.
- `Color::is_fully_transparent` is now part of the `Alpha` trait in
`bevy_color`
- `Color::r`, `Color::set_r`, `Color::with_r` and the equivalents for
`g`, `b` `h`, `s` and `l` have been removed due to causing silent
relatively expensive conversions. Convert your `Color` into the desired
color space, perform your operations there, and then convert it back
into a polymorphic `Color` enum.
- `Color::hex` is now `Srgba::hex`. Call `.into` or construct a
`Color::Srgba` variant manually to convert it.
- `WireframeMaterial`, `ExtractedUiNode`, `ExtractedDirectionalLight`,
`ExtractedPointLight`, `ExtractedSpotLight` and `ExtractedSprite` now
store a `LinearRgba`, rather than a polymorphic `Color`
- `Color::rgb_linear` and `Color::rgba_linear` are now
`Color::linear_rgb` and `Color::linear_rgba`
- The various CSS color constants are no longer stored directly on
`Color`. Instead, they're defined in the `Srgba` color space, and
accessed via `bevy::color::palettes::css`. Call `.into()` on them to
convert them into a `Color` for quick debugging use, and consider using
the much prettier `tailwind` palette for prototyping.
- The `LIME_GREEN` color has been renamed to `LIMEGREEN` to comply with
the standard naming.
- Vector field arithmetic operations on `Color` (add, subtract, multiply
and divide by a f32) have been removed. Instead, convert your colors
into `LinearRgba` space, and perform your operations explicitly there.
This is particularly relevant when working with emissive or HDR colors,
whose color channel values are routinely outside of the ordinary 0 to 1
range.
- `Color::as_linear_rgba_f32` has been removed. Call
`LinearRgba::to_f32_array` instead, converting if needed.
- `Color::as_linear_rgba_u32` has been removed. Call
`LinearRgba::to_u32` instead, converting if needed.
- Several other color conversion methods to transform LCH or HSL colors
into float arrays or `Vec` types have been removed. Please reimplement
these externally or open a PR to re-add them if you found them
particularly useful.
- Various methods on `Color` such as `rgb` or `hsl` to convert the color
into a specific color space have been removed. Convert into
`LinearRgba`, then to the color space of your choice.
- Various implicitly-converting color value methods on `Color` such as
`r`, `g`, `b` or `h` have been removed. Please convert it into the color
space of your choice, then check these properties.
- `Color` no longer implements `AsBindGroup`. Store a `LinearRgba`
internally instead to avoid conversion costs.

# Objective
- Implement grid gizmos, suggestion of #9400
## Solution
- Added `gizmos.grid(...) ` and `gizmos.grid_2d(...)`
- The grids may be configured using `.outer_edges(...)` to specify
whether to draw the outer border/edges of the grid and `.skew(...)`to
specify the skew of the grid along the x or y directions.
---
## Changelog
- Added a `grid` module to `bevy_gizmos` containing `gizmos.grid(...) `
and `gizmos.grid_2d(...)` as well as assorted items.
- Updated the `2d_gizmos` and `3d_gizmos` examples to use grids.
