----
Signals are one of those features that are extremely useful. Once you know how it, you will use it all the time. It is Godot’s implementation of the Observer pattern, an extremely common one that limits the coupling in your code. Instead of having if statements everywhere, you let your script emits a message and another object, registered as the Observer listens it. Godot calls that signals: a node emits a signal, and if another one is connected to it, it will react in consequence.
