I am trying to make a music player with Bevy and Rust. I want to use global input to check if the play/pause button has been pressed even when the window is not in focus.
I’ve tried using a number of third-party libraries to get global input. I tried using bevy_global_input, but it gives a syntax error when I try to add the plugin as seen below.
error[E0277]: the trait bound `GlobalInputPlugins: Plugins<_>` is not satisfied

I also tried using inputbot, but I need to be able to check if the key was pressed in the last frame, and inputbot only allows me to attach a callback for when the key is pressed. I tried to get around this by putting it in its own thread and making a channel to a resource. The issue I faced is that the channel makes the struct non-sync, so I can’t make a resource out of it.
I also tried using hookmap-core, but faced a similar issue. To use it I would have to hold a Receiver in a resource which causes the same issue as inputbot did.
