# 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), })) ```

//! This example illustrates how to use logs in bevy.

use bevy::prelude::*;

fn main() {
|

App::new()

.add_plugins(DefaultPlugins.set(bevy::log::LogPlugin {

|

// level: bevy::log::Level::TRACE,
|

// filter: "wgpu=warn,bevy_ecs=info".to_string(),

// here is how you write new logs at each "log level" (in "least important" to "most important"
|
|
// order)
|
|
trace!("very noisy");
|
|
debug!("helpful for debugging");
|
|
info!("helpful information that is worth printing by default");
|
|
warn!("something bad happened that isn't a failure, but thats worth calling out");
|
|
error!("something failed");
|
|
|
|
// by default, trace and debug logs are ignored because they are "noisy"
|
|
// you can control what level is logged by setting up the LogPlugin
|
|
// alternatively you can set the log level via the RUST_LOG=LEVEL environment variable
|
|
// ex: RUST_LOG=trace, RUST_LOG=info,bevy_ecs=warn
|
|
// the format used here is super flexible. check out this documentation for more info:
