The code below is part of a demo I downloaded.

public SimpleJoglApp() {
    //set the JFrame title
    super("Simple JOGL Application");

    //kill the process when the JFrame is closed
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    //only three JOGL lines of code ... and here they are 
    GLCapabilities glcaps = new GLCapabilities();
    GLCanvas glcanvas = GLDrawableFactory.getFactory()
            .createGLCanvas(glcaps);
    glcanvas.addGLEventListener(new SimpleGLEventListener());

    //add the GLCanvas just like we would any Component
    getContentPane().add(glcanvas, BorderLayout.CENTER);
    setSize(500, 300);

    //center the JFrame on the screen
    centerWindow(this);
  }

I am having a problem with the line the shown below:

1 2	GLCanvas glcanvas = GLDrawableFactory.getFactory() .createGLCanvas(glcaps);

The problem is that there is no method .createGLCanvas(). How do I get round this problem.
Thanks

I think you have mismatched versions of jogl.jar and jogl.dll. You should delete all copies of these files (and make sure you haven't dropped any JOGL-related files into the JRE/JDK, which causes problems with Java Web Start and other applications) and re-install. I'd also recommend you upgrade to the latest nightly build on the JOGL web page; there are API changes involved, but the new code is much more robust than older versions.

Hi I just downloaded the lastest build of the jogl.jar file. I opened it up to find no mension of the net file path.
My demo uses the following header files

1 2	import net.java.games.jogl.*; import net.java.games.jogl.GLU;

but the classes in the jogl.jar file are as follows.

com---------sun----------glugen----runtime
                       +-----------opengl----cd
                                             +--------impl
                                             +--------utils

etc

where is the net.game.cd path
thanks

Java Game APIs & Engines / JOGL Development / Problem with gluOrtho2D (0.0, 500.0, 0.0, 300.0)

on: 2005-12-17 15:16:03

Hi,

I am using eclipse to compile and run jogl demos. I have a very simple program to test that everything is working. However I get a bug which seems to be related to a single line in the code. This line is as follows:

1	glu.gluOrtho2D (0.0, 500.0, 0.0, 300.0);

if I comment out the line above then the application runs fine but of course all I get a blank screen. However if I include this line then i get the following errors:

Huh

I have tried all the installation tutorials that are available on the internet but I still get this problem.
I have too question....
1. How do I fix this bug . Huh

2. When will an installer be released which puts everything in the right place on its own. Grin

thanks

Hi, I want to findout all the different techniques and technologies used for computer games. For example interactive audio. Also some history of sounds/audio/music/character speech in games would also be helpful. Anyone know of any sites. thanks

Hi, yeah ok thanks I would like to see your jumping and collision code. My collision isn't that good so it would be nice to see that too. my email is zainuluk@yahoo.co.uk

Hi I have a mario style platform game, and want to make my character jump...can someone show me how to achieve this or point me to a website which would help...ok thanks bye.

7	Java Game APIs & Engines / Java 2D / Re: COLLISIONS???? HELP ME PLEASE!!!!!!!	on: 2003-01-16 10:33:42
yes, there are multiply tiles of the same tile used. However I detect collisions on some tiles but not on other....for example.......if the level consists of a black background with several clouds each made up of two tiles, say 12, and 13. The when my character movesover a tile it wll detect some number '12' tiles but some number '12' tiles will be undetected.

Java Game APIs & Engines / Java 2D / COLLISIONS???? HELP ME PLEASE!!!!!!!

Ok here is all the collsion part of my game...hope someone can help.

Ok this is the main class where everything is controlled

class MyGame{

marioCharacter = new MainCharacter(.....some parameters...);
....
//here the background is controlled
bk_level_1 = new Scene(...some parameters...);

...
//test for collision between main character and a particular tile
public void collisionCheck(Scene _level,MainCharacter _char){
      if(_level.collisionTest(_char,173)){
            collision = true;
      }
      else {collision = false;}
}

....

}

This next class is one one for the maincharacter....I will just show how the bounding box is set up every cycle.

public void updateBounds(){

      boundY = current_pos.y()+10;
      boundWidth = tileWidth-28;
      boundHeight = tileHeight-18;
      character_bounds.setRect(boundX,boundY,boundWidth,boundHeight);
}
...
}

The next class two classes are the Scene class and the tile class. The Tile class simple is each tile . here a bounding box is created round the tile.

class Scene{
...
public boolean collisionTest(MainCharacter _character,int tileNum){
      return _character.getCharacterBounds().intersects(bkCollection[tileNum].getBound());
}
...
}

ok most of it should be obvious, but it only detects some tiles.
can anyone help. thanks.
If you need anyother info then just ask.

Can anyone hlp me. ok thanks a website would be nice The code I implemented is shown below I have a problem with in the ....

:oI am a new games programmer and want to design a platform 2d game in java. but I needsome graphics, but for the background as well as for the character which will animate. i am looking cartoon style ones. i have some mario ones and a few like that but :'(I have no background. like .hif file of clouds which can move in the background. Well i have a vision of what my game will look like but I can't find the visual objects can people help me. i went to the site mentioned above but I couldn't find any. Oh this game will not be for comerical use however I will put it up on the web for people to play >:(it and tell me what they think. Also i might send it to games companies to show then what I can do.. .that is if it looks good.

Also if you have and good ideas that you think would be good(such as a particular type of level) then please do tell me. Well thats all hope someone can help me ok bye bye

15	Java Game APIs & Engines / Java 2D / Hi, PixelGrabber problems	on: 2002-12-08 10:28:04
hi. I have an applet on to which I have tiled on a background.(background made up of tiles.ie top view of a racing track). now I want to put this background in to the pixelgrabber to identify the colours(and thus do some collision detection). So all I did was import the back buffer image to the pixelgrabber. I get a run time error. Note that the backbuffer is actually an image can anyone help me.
