when using bevy-vfx-bag but also with the egui-inspector. i dont know what it does but its in my ide and on compile even when there is a Plugin implemented for it

This error is generally seen when you have two different versions of Bevy: your app may implement Bevy 0.9's Plugin trait, while the plugin you're trying to use is using Bevy 0.8's Plugin trait. Definitely a poor error message.

Use cargo tree (or inspect your dependencies carefully) to figure out where the version mismatch is coming from.

bevy-vfx-bag only works with Bevy 0.9, so your repo is probably a fork of Bevy at a previous version (0.8 or 0.9.0-dev?)

You could fork bevy-vfx-bag and try to make it work with the same Bevy version you have, or update your Bevy version. If possible, I would recommend the latter.

The problem is that im not behind. im at the newest commit of bevy. so updating mine is downgrading which isn't a good idea because i use things that were added after 0.9. so forking?

Ah, in that case you'll want to follow the advice here: https://bevy-cheatbook.github.io/setup/bevy-git.html

[mockersf]

you can patch the Bevy used by the plugin by using:

[patch.crates-io]
bevy = { path = "path/to/your/bevy" }

or however you choose to depend on your own Bevy
