Hi all,
I was wondering if it’s possible to add or remove menus from the start screen. By the start screen, I mean the screen that appears when the application first opens. I want to add a graphics menu option so that I can set custom presets in my game. Is this possible?
Thanks
What you mean is refered to as the StartDialog / AppSettings.
I think per default you can only change the splash screen of it, but it should also possible by overriding the correct values and then returning a regular awt panel/swing jPanel/Frame whatever that is, just examine the code a bit and tell us if you’re having problems there.
Oh and you should probably use the AppSettings class there as that’s what is used by jme as well.
As-is you can mostly only tweak the image and the title text. It’s way easier to just make your own launcher in JavaFX or Swing though, since you can also avoid many other problems and issues that the default launcher has. Like not detecting refresh rate on iOS for example. It’s generally a poorly made placeholder.
Yep, it falls into the same category as FlyCam and simpleUpdate()… ie: the first things you will replace when you make a real game.
Does something like this work:

}Like fallout or whatever. A separate application that gathers settings and launches the main game. You should probably pass the data as command line args to the game so you can keep them separate. Additionally you have the benefit of bypassing the launcher and creating an icon with args. Simple things make life simple 
Why does a settings dialog extend application? How many applications do you want in your application?
That’s for JavaFX.
That’s not the issue @pspeed is saying: why are you making your settings dialog a JMonkey Application?
It’s not a jMonkey application. It’s a JavaFX application.
My import:
import javafx.application.Application;
Oracle’s tutorial:
Yeah, it’s not… I didn’t read too deeply before commenting. I just get triggered by “extends Application”.
The JavaFx construct is still pretty weird but that’s not really OP’s fault. All of the good Java designers left after Oracle bought Java, I guess.
