Ya that fixed it, thank you.

I totally am, I'll adjust it. Sorry I've been programming this non-stop since Monday, think I'm getting sloppy.

And Rebirth, the change to the way I handle the connection info works wonderfully, thank you. But I needed to keep it in the GameState, But I adjusted based on what you said

If I try it that way it throws an error about not having a state with an ID of 0, so they are not initialized at all (I'm assuming), even if I leave the

1 2	this.getState(MAINMENUSTATE).init(gameContainer, this); this.getState(GAMEPLAYSTATE).init(gameContainer, this);

sections in, once the .addstate() code is moved it doesnt work.

Full source is uploaded, and I could try that, but that sounds like a messy workaround, considering that the initStatesList() is meant as a list to declare what to init (or so I thought) and basically SHOULD do the same thing. I probably just messed up something in my declarations that I didn't notice cause I am quite new to the Slick2D lib

I'll post the full source, but the issue is that it's even running that code, I don't need that code until it has the data that I declare earlier in the program. Basically in the menus I get the user to login, then it sends those credentials to the server in the GameState. But on Launch the GameState init() is being run when I dont want to call it until I need it. Ill post full source code once I copy it to the bin, but would there be a better way to approach something like this?

sorry forgot to put it in, it's there now. Is there anything else that I should include to make this easier? like the gameState init()?

on: 2012-06-13 08:48:50

Seems like my game state is being initialized even though I have it commented out in the initStatesList(...) is there a reason for that? I have it initializing network code would that affect the initializing?

the exact error im getting is:

Unable to get I/O connection to: localhost on port: 1967

but the only connection attempt to localhost is in the game state

Heres my initStatesList:

public void initStatesList(GameContainer gameContainer) throws SlickException {
        this.getState(MAINMENUSTATE).init(gameContainer, this);
        //this.getState(GAMEPLAYSTATE).init(gameContainer, this);
        this.getState(VICTORYSTATE).init(gameContainer, this);
        this.getState(OPTIONSSTATE).init(gameContainer, this);
}

and the states added to the state list:

super("Title");

this.addState(new MainMenuState(MAINMENUSTATE));

That worked, thank you very much

Game Development / Newbie & Debugging Questions / [Slick2d] [input] Keys and mouse firing too fast

on: 2012-06-13 03:35:10

Hey I'm having an issue were, when clicking on a button or when clicking a key, the key or mouse click fires like 10 responses (restricting my game to 30fps reduces the number to that, without the fps reduction its closer to 100) I'm just wondering how I can maintain that when I click or hit a button, it with only receive one response?

heres some of my input code:

// Play button
if( ( mouseX >= 0 && mouseX <= play_button.getWidth()) && ( mouseY >= 90 && mouseY <= 90 + play_button.getHeight()) ){
   insidePlay = true;
}

if(insidePlay){
   if(playScale < 1.015f)
      playScale += scaleStep * delta;
             
   if ( input.isMouseButtonDown(Input.MOUSE_LEFT_BUTTON) ){
           if(!isLogin) {
                 tryLogin = true;
              } else {
                 sb.enterState(CodaClient.GAMEPLAYSTATE);
              }
         }
 }else{
        if(playScale > 1.0f)
            playScale -= scaleStep * delta;
 }

EDIT: Sorry if there's another thread with a similar question, I searched threw a few pages but wasn't sure what this exact issue is called, so I didnt find much that helped.

13	Game Development / Newbie & Debugging Questions / Re: Need help swapping between States	on: 2012-06-12 05:51:08
FIXED: It didn't have to do with the states at all, it was the in the mouse check, was exiting the display if it was outside every button (which it would be no matter what).

Game Development / Newbie & Debugging Questions / Need help swapping between States (FIXED)

on: 2012-06-12 05:35:07

Hey, I'm having difficulty figuring out why I cannot swap between 2 different states, the game just crashes after I click the button to make the switch. Was just wondering if someone could give me a hand?

I run the game, click on the high scores button, then the display closes. I was following the SlickBox example http://slick.cokeandcode.com/wiki/doku.php?id=02_-_slickblocks

Sorry about the wall of code, but I really don't know were the issue is.

EDIT: after a bit more debugging it seems to be on the input, when I click anywhere on the screen, it just closes the display, is there anything that could be causing that?
