Part 4 – User Interface

The final piece your game needs is a user interface (UI). This is an interface to display information that the player needs to see during gameplay. In games, this is also referred to as a Heads-Up Display (HUD), because the information appears as an overlay on top of the game view. You'll also use this scene to display a start button.

The HUD will display the following information:

• Score
• Time remaining
• A message, such as Game Over
• A start button

Node setup

Create a new scene and add a CanvasLayer node named HUD. A CanvasLayer node allows you to draw your UI elements on a layer above the rest of the game, so that the information it displays doesn't get covered up by any game elements...
