LibGDX - implements ApplicationListener or Extends Game?

Newbie & Debugging Questions
#1

Hey guys, i’m rewriting my brickbreaker game to clean up code a bit, add a few things, etc. I’ve found a couple of tutorials for making screens, but i’m a bit confused about one thing in particular. I have my main class which is Game.java. In Game.java the class Implements ApplicationListener. I know I need to implement the application listener, but all of the tutorials are telling me, it should extend Game instead.


public class Game implements ApplicationListener {

I made another class thinking that, that should be my main class and it should extend game…But it doesnt seem right. I’m not sure I explained it correctly…Let me know if you understand what i’m saying.

I have a main class that extends libgdx’s Game class. This class will switch my screen(s).

#3

Game is an abstract class that implements ApplicationListener, so you do not have to implement ApplicationListener yourself.

#4

So, in my main Game.java class it should be:

public Game extends Game

instead of

public Game implements ApplicationListener
?

I used the GUI setup tool to create the project and the latter was used, (implements ApplicationListener.)

So basically, if I make (my)Game extend Game, it will implement ApplicationListener as well, correct?

Right, and to prevent ambiguity change your class’s name, like Main or else.

#6

Pretty much, but it implements ApplicationListener itself. Game is basically just a Helper class to be used with the Screen interface. This is an easy way to set up multiple screens, like a menu screen, a options screen, the actual gameplay screen, etc.

Exact implementation is here.

#7

extends ApplicationAdapter.

#8

we do: implements ApplicationListener

Differences, benefits ?

#9

It implements all the methods so you only have to implement the ones you care about. No difference other than that.

100% made to make your code cleaner ;D override needed only.
