App runs but window does not appear and app does not loop

[alice-i-cecile]

I've been working on a template repo for Bevy games and libraries.

The file structure is slightly different than the typical: both a main.rs and lib.rs exist within the src file, and main is recorded as bin in Cargo.toml.

When I call cargo run, my app runs "successfully", printing `Hello, World!".
However:

• no main window appears
• the app does not loop: each main stage runs exactly once
• no errors, warnings or other diagnostics appear

This is isolated to this project, other simple demos and existing projects work totally fine.

I suspect the project structure is somehow interacting badly with the default winit-powered runner, but I have no idea how or why. Any thoughts would be welcome!

You don't have the winit feature enabled in your bevy dependency, so the winit runner isn't on the default plugins

This is expected behaviour

As a side note, you need to add the WindowDescriptor before the DefaultPlugins, because otherwise it won't be registered properly.

Aha! Curse my split design. Let me test this out.

That worked! Thanks; sometimes it's incredibly hard to spot the obvious stuff when you've been staring at a project all day.
