scene.rs example crashes

[gabriel-gheorghe]

Bevy version

Bevy 0.6.1

Operating system & version

Windows 10

What you did

Run examples/scene/scene.rs

What actually happened

thread 'main' panicked at 'scene contains the unregistered type scene::ComponentB. consider registering the type using app.register_type::()' file src\scene_spawner.rs:333:35

I was going to look into this, but the example is running fine for me. I'm running Win 11, but not sure that'd make much of a difference.

Could you describe the exact steps you took to run this.

Did you simply clone the repository with the main branch and then ran cargo run --example scene?

Hey guys, I can reproduce this as well on Windows 10.

On a clean project with only the bevy dependency (0.6.1), copy the example code to the main.rs, also add the assets folder.
Running cargo run results in the error.

I have no idea sure why, but if I copy the same file to examples/scene.rs of this clean project and run cargo run --example scene it works.

I tried both nightly and stable toolchain.

[mockersf]

This is normal if you copy the code somewhere else.
In the scene, ComponentB has been serialised as scene::ComponentB, so the struct must be declared under a root binary named scene

bevy/assets/scenes/load_scene_example.scn.ron

Line 23 in 30878e3

"type": "scene::ComponentB",

Oh I didn't know that, was just testing the scene example to try to learn from it.
Thanks for the info @mockersf !

@themilkybit maybe your issue is the same misunderstanding?

Still broken on main (69760c7):

2024-01-13T14:53:16.822805Z ERROR bevy_asset::server: Failed to load asset 'scenes/load_scene_example.scn.ron' with asset loader 'bevy_scene::scene_loader::SceneLoader': Could not parse RON: 8:6: The given id is not a valid entity.

But this is likely due to e6a324a I think. FYI @Bluefinger

This is also to do with #9907 as now the Entity format has changed so that 0 is an invalid u64 value to deserialize an Entity from. This current fix is here #11289
