Doc/module style doc blocks for examples (#4438) # Objective Provide a starting point for #3951, or a partial solution. Providing a few comment blocks to discuss, and hopefully find better one in the process. ## Solution Since I am pretty new to pretty much anything in this context, I figured I'd just start with a draft for some file level doc blocks. For some of them I found more relevant details (or at least things I considered interessting), for some others there is less. ## Changelog - Moved some existing comments from main() functions in the 2d examples to the file header level - Wrote some more comment blocks for most other 2d examples TODO: - [x] 2d/sprite_sheet, wasnt able to come up with something good yet - [x] all other example groups... Also: Please let me know if the commit style is okay, or to verbose. I could certainly squash these things, or add more details if needed. I also hope its okay to raise this PR this early, with just a few files changed. Took me long enough and I dont wanted to let it go to waste because I lost motivation to do the whole thing. Additionally I am somewhat uncertain over the style and contents of the commets. So let me know what you thing please. 2022-05-16 13:53:20 +00:00			`//!

Merge AppBuilder into App (#2531) This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet. You can use `git diff --diff-filter=M eb8f973646476b4a4926ba644a77e2b3a5772159` to find all differences in this PR. The `--diff-filtered=M` filters all files added in the original commit but not in this commit away. Co-Authored-By: Carter Anderson <mcanders1@gmail.com> 2021-07-27 20:21:06 +00:00			`App::new()`
Break `CorePlugin` into `TaskPoolPlugin`, `TypeRegistrationPlugin`, `FrameCountPlugin`. (#7083) # Objective - Fixes #7081. ## Solution - Moved functionality from kitchen sink plugin `CorePlugin` to separate plugins, `TaskPoolPlugin`, `TypeRegistrationPlugin`, `FrameCountPlugin`. `TaskPoolOptions` resource should now be used with `TaskPoolPlugin`. ## Changelog Minimal changes made (code kept in `bevy_core/lib.rs`). ## Migration Guide - `CorePlugin` broken into separate plugins. If not using `DefaultPlugins` or `MinimalPlugins` `PluginGroup`s, the replacement for `CorePlugin` is now to add `TaskPoolPlugin`, `TypeRegistrationPlugin`, and `FrameCountPlugin` to the app. ## Notes - Consistent with Bevy goal "modularity over deep integration" but the functionality of `TypeRegistrationPlugin` and `FrameCountPlugin` is weak (the code has to go somewhere, though!). - No additional tests written. 2023-01-05 11:42:35 +00:00			`.add_plugins(DefaultPlugins.set(TaskPoolPlugin {`
Use plugin setup for resource only used at setup time (#6360) # Objective - Build on #6336 for more plugin configurations ## Solution - `LogSettings`, `ImageSettings` and `DefaultTaskPoolOptions` are now plugins settings rather than resources --- ## Changelog - `LogSettings` plugin settings have been move to `LogPlugin`, `ImageSettings` to `ImagePlugin` and `DefaultTaskPoolOptions` to `CorePlugin` ## Migration Guide The `LogSettings` settings have been moved from a resource to `LogPlugin` configuration: ```rust // Old (Bevy 0.8) app .insert_resource(LogSettings { level: Level::DEBUG, filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(), }) .add_plugins(DefaultPlugins) // New (Bevy 0.9) app.add_plugins(DefaultPlugins.set(LogPlugin { level: Level::DEBUG, filter: "wgpu=error,bevy_render=info,bevy_ecs=trace".to_string(), })) ``` The `ImageSettings` settings have been moved from a resource to `ImagePlugin` configuration: ```rust // Old (Bevy 0.8) app .insert_resource(ImageSettings::default_nearest()) .add_plugins(DefaultPlugins) // New (Bevy 0.9) app.add_plugins(DefaultPlugins.set(ImagePlugin::default_nearest())) ``` The `DefaultTaskPoolOptions` settings have been moved from a resource to `CorePlugin::task_pool_options`: ```rust // Old (Bevy 0.8) app .insert_resource(DefaultTaskPoolOptions::with_num_threads(4)) .add_plugins(DefaultPlugins) // New (Bevy 0.9) app.add_plugins(DefaultPlugins.set(CorePlugin { task_pool_options: TaskPoolOptions::with_num_threads(4), })) ``` 2022-10-25 22:19:34 +00:00			`task_pool_options: TaskPoolOptions::with_num_threads(4),`
