er…in my case…which part of my program need to modifiy???
JavaCoolDude’s Demo the WaterSimulation can not execute…
java.lang.Error: Cannot load image Data/Water.png
please help
fun fun fun ;D
/me stabs self in the face with a soldering iron :
hahahaa…i don’t know what happen actually…
i usually download the source code and put it on my desktop…and run the program…
or should i put the program to c: or else???

With Kevin’s 3ds loader I experienced the same problem - because I don’t put the app’s resource paths into the classpath.
Let’s asume your Java application stays in a folder with a subfolder “models/”, where the models as well as their textures are. In addition to the model’s InputStream we’ve to give the “models”/ path to the loader, too, in order it can find the textures. From the three (+) possibles ways to create a TDSLoader I can only use this one:
final String pathname = "models/";
final String modelfile = "Yourmodel.3ds";
InputStream bis = FileInputStream(pathname + modelfile);
TDSLoader dslader = new TDSLoader();
dslader.setGenerateMipMaps(true);
TDSModel model = dslader.load(pathname, bis, true);
This way it works fine, no matter how you start the Java application: via dosbox (java -cp …), or via double click on your App.jar, or at a friend’s PC (again with emtpy CLASSPATH).

any problem in my program??
Posting the whole program is excessive, especially not in a code block…
Based on previous posts, I’ll start with the obvious, do you have a file at the path “model/character.3ds” ?
yes i do have…is like this
c:\xith-3ds\model\character.3ds
i even put the character.3ds here
c:\xith-3ds\character.3ds
but still can not locate the file…and one more, even if i change the file name like this
final String pathname = "model/";
final String modelfile = "cube.3ds";
it still display the error message
*java.io.IOException: Not found: model/character.3ds
instead of
*java.io.IOException: Not found: model/cube.3ds
please tell me why it still look for character.3ds only but not for cube.3ds…i tried other files but still look for chracter.3ds
thanks

Check the jar file for the loader and see if it has a class file in there with the same name as yours. I think you may not actually be executing your code, but code from the jar itself…
is it the xith-3ds.jar??? i do checked it, i execute but give me this
Failed to load Main-Class manifest attribute from
c:\xith\xith-3ds.jar
im using netbeans-ide as you know…
As stated before by others, you really need to brush up on Java basics.
Dont execute the Jar, open it up and look inside it. I think you’re gonna find a class file in there with the same name as yours. You’re going to want to remove it from the jar, or rename your class so it doesnt conflict.
Renaming your class may be easier for you.
im very sorry about this…im learning the basic java at the moment…other than Xith
any nice loader that can load animated .3ds recommend to me? thanks alot
This is just getting silly:
- Extract the contents of zip file. In there you will find:
- TDSTest.java - an example of how to use the loader
- org - the source for the loader, you won’t need this, and can just delete it.
- xith-3ds.jar - The jar file containing the binaries you need to use the loader.
-
Get a basic Xith demo running
-
Classpath through the xith-3ds.jar
-
Compile TDSTest.java
-
Run TDSTest
Kev
??? :-X
dude, you just went in a complete circle. You are wasting countless peoples time. Did you even read my last post?
I’m pretty sure my solution will fix your loading problem. But you’re gonna have lots of other issues because of your lack of fundamentals.
I wanted to program games in Java for a while, but it took quite a while to get the basics down, and I still have problems. Just takes time and experimentation.
im very sorry SpuTTer, i just asking only…i still want to learn Xith…please forgive me :-[ :’(
i did open the xith-3ds.jar inside got TDSTest.class, and i rename my class but still have the same error…
thanks
You renamed it, so I guess its not conflicting. What command line are you using to run the program?
you are compiling it after you make changes right?
Re: The loader--------
You already asked about a loader for animation. In fact, you made an entire posts about it:

Make sure you can handle Xith3D - open this in Java Web Start http://xith.org/jws/jws-org.xith3d.gsg.HelloXith3D.jnlp (if you can’t - google for help).
-
Install Xith3D http://xith.org/installing.php
-
Bury youself in the tutorial - http://xith.org/tutes/GettingStarted/html/ Make sure you can compile Java programs. If not - google for help.
-
Think about using third party API’s such as the 3ds loader.
Will.
before compile i rename the TDSTest.java…im using NetBeans0IDE…so im not sure what command lines is using…since in NetBeans-IDE can easily compile program by just clicking the “execute icon” to F6.
