Game Screens - UQdeco2800/2022-studio-1 GitHub Wiki
Introduction
The game contains several screen which which each implement libgdx's ScreenAdapter interface. Screen are responsible for initiating important game services, loading screen resources, drawing the background and UI, rendering the entities, handling input, etc.
Only one screen is shown at a time and GDXGame.java
contains functionality for transitioning between screens. Screen transitions are triggered by the current screen.
Within the base game, there are 3 screens: Main Menu Screen, Main Game Screen, and Settings Screen. The Main Menu Screen is the starting screen.
Screens can also be split into different Game Areas which can be used to create different levels and areas. Read more here!
