Hello guys
I now whant to make a main menu for my game..
Problem is that the library i'm using is not working too well with swing..
So.. instead of swing what should i use?

Library is called : Slick 2D

You're going to have to be more specific. Not working how?

Also, from looking at Slick2D's forums, you can use CanvasGameContainer to hold your Swing elements.

Oh... I will look into it, Also can you link me to that thread?

But if you check the class AppGameContainer here : http://slick.cokeandcode.com/javadoc/

Is there no way i can just add a button to that ?

[macosxnerd101]

I'm honestly not familiar with that library at all. We don't have the best support with all the third party APIs, so I'm not sure how to advise you with your Slick2D.

Hmm Alright.. But it my situiatoin what would you do? Any advice or tips?

[macosxnerd101]

I probably would have started with Swing to begin with, or found a library that I could evaluate would suit my needs. And if it didn't work, then I would change libraries. Since I separate my GUI from my program state/data, I would be able to salvage a lot of code and just have to deal with redoing some of the UI components.

Alright thanks for the advice.

Which features of Slick2D do you use that are not available within Swing ?

[TheCompBoy]

I tried adding a swing JFrame to my application here is the error:

Exception in thread "main" java.lang.NullPointerException
at java.awt.Container.addImpl(Unknown Source)
at java.awt.Container.add(Unknown Source)
at galactic.adventures.Galacticadventures.main(Galacticadventures.java:54)

Here is the code:

    	JFrame frame = new JFrame("Galactic Adventures");
    	frame.setSize(800, 800);
    	Container content = frame.getContentPane();
    	content.setLayout(new FlowLayout());
    	content.add(newGame);
    	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	frame.setVisible(true);

And here is the variables that i create with the class:

	JFrame frame;
	static JButton newGame;

Obviously your newGame button is not initialized
And why static ???

When i first wrote it i got error it saying i can fix it by changin to static.

[macosxnerd101]

I'm betting the error was something like "non-static variable cannot be referenced from static context." When working with OOP, don't make something static unless you understand why it should be static. Chances are, if a static element is accessing a non-static element, making the non-static element static is the quick and dirty fix.

Alright thanks, I will remember this..
