Difference between Res<Input<MouseButton>> and EventReader<MouseButtonInput>?

[Metadorius]

Those two seems pretty similar, what's the difference between them and which should be used when?

For most input types (where it makes sense), Bevy provides two ways of dealing with them:

• by checking the current state via resources (input resources),
• or via events (input events).

Events (input events) are a lower-level, more all-encompassing approach. Use them if you want to get all activity from that class of input device, rather than only checking for specific inputs.
