This plugin provides a new node BackgroundWorker to make it easy to queue up and track background tasks.
This can be used to preload scenes, save games, synchronize or upload files, etc.
All queued up jobs are processed by an adjustable amount of worker threads. For strict linear processing "one after the other" you can reduce the number of active worker threads to one.
Progress is reported back through signals, although hooked up functions can still trigger their own signals from their own thread in case you need it.
The latest version of the addon can be found in my repository.
As with any other Godot addon, put the contents of addons/BackgroundWorker in your own project's addons directory and make sure to enable it in Project Setting's "Plugins" tab.
To queue up new jobs, call the member methods queue_job(target, method, [binds]) or queue_load(file, [type_hint]). Processing starts automatically on the next frame.
