Adding a plugin to a stage

[DomonkosSuranyi]

Hi all!
Is there any way to add a plugin to a stage? If there's no such way I'm curious to the reason why.

My concrete issue:
On the game server I most of my systems should run at a fixed framerate.
I've found one way to do so: Adding the systems to a custom stage where I set run criteria to FixedFramestep.
The issue is that there are Plugins too that I would like to run with exactly the same timestep but I couldn't find a way to add the plugin to my FixedUpdate stage.

The same issue occurs when I want a plugin to run only in a specific state.
E.g. at "Connecting" state (where client tries to connect to server) I don't really need the CollisionPlugin to run...

There currently isn't. A plugin may currently add systems to any and all stages it wants. You may be interested in bevyengine/rfcs#45.

Ask plugin authors to add a configuration flag named dont_register_your_systems_let_me_do_it_instead.

Then register their stuff manually, here's an example how to do this with rapier3d:
