Does my game work on your machines?

[sthorsen]

Hi!
Just made this tetris clone using lwjgl. I wonder if it works on your machines?

And I would be happy if you would tell me your OS/Browser/GraphicsHardware details wether or not it works

wont even start. I see the webstart stuff with a "random industries" sign, and then nothign happens

gforce 3 ti200,windows XPpro , firefox

[sthorsen]

Middy>> Does it freeze at "Starting application" because I've seen that on a number of other machines which all had in common that no lwjgl had been executing on them before.
Any ideas what the problem can be?

Thanks to both of you for using some of your friday afternoon time on this!

[Middy]

yes it does, but I have run several LWjGl apps on it before using webstart, and nope I have no idea. I am using java  1.4.2_04 btw (not 1.5 as I stated)

[sthorsen]

Hmm ok. Can u see anything wrong in my php/jnlp file?

I guess you've been compiling with a 1.5 SDK, right?

Fails to download correctly here

Kev

[sthorsen]

yup! Compiled using 1.5 SDK! What's the problem with that? Does it work if I change my code to compile with an older version?

[elias]

I think you need to specify -target 1.4 to the 1.5 javac to make it generate 1.4 compatible class files.

- elias

[sthorsen]

Just compiled without option -source 1.5 and it works on all machines I've encountered. Does it work on yours now?
Thanks for your help everyone!

Søren

[elias]

I'm sure you meant "-source 1.4" Anyway, it works fine now.

- elias

[karatemarkel]

No problems here, XP Pro, firefox, 6800 GT and 1.4.2_01.

[sthorsen]

I meant what I said which was compiling with "bla bla bla" instead of "-source 1.5 bla bla bla". I think 1.4 is the default option so no need to specify it...
Anyway i'm glad it seems to work on most machines. Please let me know if I'm wrong!

[Middy]

works

[sthorsen]

Nice!  

[Middy]

sthorsen, how did you compile your 1.5 code to 1.4 compatible. Cause I cant make it work

[sthorsen]

I changed the few lines with 1.5 specific code to 1.4 compatible code and the compiled it with:

javac -classpath "$[ClassPath]" -d "$[OutputPath]" $[JavaFiles]

The javac.exe is still the 1.5 compiler but it compiles to 1.4 by default.

[Middy]

damn... I dont want to change my code and I cannot compile it to 1.4 code...


Well shrew it you'll get a webstart in a year or so (when 1.5 is out)

Would have been, if only it weren't using JOGL!

[renanse]

Would have been, if only it weren't using JOGL!

 What are you talking about.  Check your javaws cache, it uses lwjgl.

[sthorsen]

Thanks cas!  

I use LWJGL for rendering and input and pure java for the rest. No JOGL!

edit: And of course php/mysql for the hiscore part. That should cover it  

[cfmdobbie]

 What are you talking about.  Check your javaws cache, it uses lwjgl.

Hmm, than I take it all back.

It crashed out on my laptop, and my Webstart log contained a JOGL stack trace - I checked the timestamp, and was pretty sure Retris created it.  I must have been mistaken!

[EsotericMoniker]

It runs fine for me but the background graphic has interlaced black lines running through it.  I'm not sure if that was intentional.  I can send you a screen shot if you would like.

Specs:
Dell Inspiron 9100
Radeon Mobility 9700 128MB
XP Pro SP1
JVM 1.4.2_05-b04

[sthorsen]

I know about the interlaced lines - but I'm not sure how to fix it. Does anyone have an idea what can be wrong? The image for the texture measures 800x600 pixels and I use the following code to generate the texture:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36   37   38   39   40

private static int loadTexture(String path) {             java.net.URL url = Thread.currentThread().getContextClassLoader().getResource(path);             Image image = (new javax.swing.ImageIcon(url)).getImage();             // Exctract The Image            BufferedImage tex = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_3BYTE_BGR);             Graphics2D g = (Graphics2D) tex.getGraphics();             g.drawImage(image, null, null);             g.dispose();             // Flip Image            AffineTransform tx = AffineTransform.getScaleInstance(1, -1);             tx.translate(0, -image.getHeight(null));             AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);             tex = op.filter(tex, null);             // Put Image In Memory            ByteBuffer scratch = ByteBuffer.allocateDirect(4 * tex.getWidth() * tex.getHeight());             byte data[] = (byte[]) tex.getRaster().getDataElements(0, 0, tex.getWidth(), tex.getHeight(), null);             scratch.clear();             scratch.put(data);             scratch.rewind();             // Create A IntBuffer For Image Address In Memory              IntBuffer buf = ByteBuffer.allocateDirect(4).order(ByteOrder.nativeOrder()).asIntBuffer();             GL11.glGenTextures(buf); // Create Texture In OpenGL                           // Typical Texture Generation Using Data From The Image             // Linear Filtering          GL11.glBindTexture(GL11.GL_TEXTURE_2D, buf.get(0));           GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MAG_FILTER, GL11.GL_LINEAR);           GL11.glTexParameteri(GL11.GL_TEXTURE_2D, GL11.GL_TEXTURE_MIN_FILTER, GL11.GL_LINEAR_MIPMAP_NEAREST);             GLU.gluBuild2DMipmaps(GL11.GL_TEXTURE_2D, 3, tex.getWidth(), tex.getHeight(), GL11.GL_RGB, GL11.GL_UNSIGNED_BYTE, scratch);                         return buf.get(0); // Return Image Address In Memory      }

it works.
