Hi, I wasn't able to find an nice way to get access to godot InputEvent handles that are normally passed via _input or _unhandled_input in nodes. I went ahead and made a very rough draft (partly as a learning exercise for myself) of getting these into bevy events here: https://github.com/jrockett6/bevy_godot/tree/godot-input-to-bevy-events

If there already exists a good way to get access to InputEvent information I'd be curious to hear. Otherwise I'd be happy to open up a PR with the above changes and incorporate any feedback (I'm very new to the rust/godot/bevy ecosystem).

Thanks very much for your awesome library!

Bevy's asset server first checks if the file exists at the path and then continues the loading. A workaround is placing an empty file at the paths not found.

Not sure how we can work around this as we need Bevy's asset server to not care if the file exists because we map the filepath into the Godot res:// paths.

Pass InputEvents that are normally caught in _unhandled_input(input: InputEvent) in Godot into Bevy events, giving us access to the InputEvent information.

Also adds an associated example.

Issue #13

New bevy_godot features:

• fix(scene_tree): rework scene tree initialization to be correct for startup systems
• feat: add Godot signals
• feat(2d): add Transform2D and updating systems
• fix: move post update godot transform systems to Last
• feat(2d): removed additional check that prevented 2D collisions from working

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }', spawn_scene/../run_godot.rs:11:10

BREAKING CHANGES:

• The Bevy app will update on the visual frame and physics frame. Use of Time's delta may lead to unexpected values when systems are scheduled for the visual frame or physics frame. Consider using the SystemDelta to keep track of your own delta time.

Features:

• Update to Bevy 0.8
• Bevy Assets integration. Assets with a path ending with .tscn, .scn, .tres, and .res will be loaded with Godot's interactive loader
• Godot scenes can be spawned from an Asset Handle
• Godot object references can be used as an Asset
• Full implementation of the Dodge the Creeps example game
• Systems can be scheduled to only run on the visual frame or physics frame
• SystemDelta system param to keep track of a system's own delta time
• Errors rising from the internal NativeClasses will have a source location in the library

New bevy_godot features:

• Catch bevy app panics and prevent re-entry
• Removed GodotReference type
• ErasedGodotRef has added bounds to prevent misuse with Godot reference counted types

this would unify the code path for creating a Bevy entity from Godot nodes.

the end user would like a way to query added Godot nodes and also receive the ones found at startup.

to maintain compatibility also upgrade:

• bevy_asset_loader to 0.14
• iyes_loopless to 0.9

migration guide: https://bevyengine.org/learn/book/migration-guides/0.8-0.9/

I think all code changes fall into one of these categories (copied from migration guide):

Add #[derive(Resource)] to all types you are using as a resource.

Plugins own their settings. Rework PluginGroup trait.

// Old (Bevy 0.8)
let dur: Duration = time.time_since_startup();
let secs: f32 = time.time_since_startup().as_secs_f32();
let secs: f64 = time.seconds_since_startup();

// New (Bevy 0.9)
let dur: Duration = time.elapsed();
let secs: f32 = time.elapsed_seconds();
let secs: f64 = time.elapsed_seconds_f64();

// Old (0.8)
commands.spawn()
  .insert_bundle(SomeBundle::default())
  .insert(SomeComponent);

// New (0.9) - Option 1
commands.spawn_empty().insert((
  SomeBundle::default(),
  SomeComponent,
))

Testing

All examples were ran successfully on my M1 Mac, except for dodge_the_creeps which fails with godot import errors. Though it should be migrated successfully.
