Game Development / Newbie & Debugging Questions / loading textures on 64bit VM
|
on: 2010-02-13 13:05:25

hello, it seems my texture loader doesnt work anymore when run in a 64bit environment. im not sure if the cause is the 64bit VM itself or if the file lying on a 64bit filesystem. the image to load is a RGBA png file. here is my code: 1

does anyone know what could be wrong? thanks! |

thank you!
the reason why i would like to resuse the same keystore is, that i use more than one jar. for example libaries are in their own jars. and afaik the user has to accept one security warning per keystore. and i dont want him to have accept more than one.

Java Game APIs & Engines / Tools Discussion / webstart with nativelibs
|

hello, when i look at some webstart files, i see that they use something called nativelib. these jars seem to contain just the nativelibraries (dlls, so, ...) example: 1

<resources os="Windows">
<nativelib href="lwjgl-native.jar"/>
</resources>
<resources os="Mac OS X">
<nativelib href="lwjgl-native.jar"/>

my questions is: how do you create these nativelib-jars? is there an ant task for this? thanks! |

-keep public class * {

}

as soon as i put in the -dontoptimize option, it works. according to the stack of the exception it crashes when accessing a static public member of a class with a nullpointer. what could be the problem? thanks! |

hello i use a keystore file to sign my jars. now it says it has been expired. is it possible to update it without recreating it?

"The signer certificate has expired."

well, i did look at those replies, but maybe i am not getting things here...
only thing i can say is, that in my shaders i use glUniform with the id of the texture objects and it works perfectly like this:
glUniform1i( location, texture.getId() );

hello, i have a zip file that contains images, which i want to load so that they exist as BufferedImages.
i already got so far, that i have a ZipEntry and the corresponding BufferedReader but how can i convert the stream from the BufferedReader into a suitable format that is accepted by the ImageIO class?
thanks!

the jogl-dds loader crashes for me with this stack: java.lang.NullPointerException at com.sun.opengl.util.texture.TextureData.<init>(TextureData.java:258) at com.sun.opengl.util.texture.TextureIO.newTextureDataImpl(TextureIO.java:842) at com.sun.opengl.util.texture.TextureIO.newTextureData(TextureIO.java:250) at com.sun.opengl.util.texture.TextureIO.newTexture(TextureIO.java:538) lhkbob, yeah i would be happy to have a look at your dds reader!  btw: does anyone know of a good standalone TGA loader/writer for java? |
