How do I use an image plugin with nearest sampling?

[vurpo]

I attempted to just add ImagePlugin::default_nearest(), however starting the app with this results in:

thread 'main' panicked at 'Resource requested by (bevy_ecs::system::system_param::Res<bevy_render::renderer::render_device::RenderDevice>, bevy_ecs::system::system_param::Res<bevy_render::texture::image::DefaultImageSampler>) does not exist: bevy_render::texture::image::DefaultImageSampler', /Users/tilde/.cargo/registry/src/github.com-1ecc6299db9ec823/bevy_ecs-0.9.1/src/system/system_param.rs:412:17

This is on macOS.

The previous discussions about this I can find mention ImageSettings, which seems to be gone entirely by now. What's the right way to get nearest sampling for images?

You can use the set method on DefaultPlugins to configure ImagePlugin.

This is exactly what I tried doing, resulting in the error above (sorry if that wasn't clear enough)

Actually that's what I thought I was doing. I don't know what the difference is, but previously I tried to create the DefaultPlugins object with the configured ImagePlugin separately before adding it to the app, but now that I wrote it inline all on the same line (like the example says) it stopped crashing.

So there are a couple concerns that using set on the DefaultPlugins PluginGroup solves.

• ImagePlugin needs RenderPlugin to be set up first.
  You were seeing the sort of error you were seeing because you were adding ImagePlugin before DefaultPlugins
• We can't add a second copy of ImagePlugin after DefaultPlugins adds its own.
  You would see another sort of error if you had added ImagePlugin after DefaultPlugins

With set, we can tell DefaultPlugins to use our configured version of ImagePlugins when the plugin group is built, with everything in the right order.
