Скачать или смотреть Node Communication! Using Signals for UI Interaction (Godot 4.5) | Buttons and Decoupling

Godot Dev Checkpoint: Time to build a working menu! This video is all about decoupled communication using Signals. Building on our physics lesson, we show how to make UI nodes (Buttons and Labels) interact safely and efficiently.

You will master:

Control Nodes: Understanding the Control root node for building all UI.

Signal Emitters: Finding and connecting the pressed() signal from a Button using the Node Tab.

Decoupling: Using the Signals system to ensure the Button doesn't know what happens when it's clicked, only that it needs to tell someone.

Child Access: Using the handy $ operator in GDScript to easily access child nodes like our Label.
