Exporting Signals

[polar locust]

My player (scene) has HP variable which I would like to show in the canvas outside of the player.
Is there a good way of exporting this signal I'm sending so the UI will be able to listen to this signal

A global event bus could solve that.
Or you use editable children which exposes the signals also.

Or a UI singleton you can access from player
