i use this code


Object3D[] miss=Loader.load3DS(getFile("3ds"+c+"weapon.3ds"), 2);

    public java.io.InputStream getFile(String File)
    {
        return (RMain.class.getClassLoader().getResourceAsStream(File));
    }

The load3DS method takes 2 parameters, a string with the 3ds file path and a scale, you are not passing a path as String but a inputStram turned as String

your new code should be:

Code: [Select]



Object3D[] miss=Loader.load3DS (getFile, 2);

public String getFile (String File) {
    return File;
}



the error mesage is clear enough: ERROR: Couldn't read file from InputStream

No, InputStream is fine. The Loader supports it. Try to load it from "3ds/weapon.3ds" instead of using the separatorChar in the path name. If it doesn't work, double check your jar to see if the file is really where it's supposed to be.

yes it works.I use the following :arrow:


 InputStream inputstream = getFile("3ds/weapon.3ds");
        Object3D[] miss = Loader.load3DS(inputstream, 2.0F);



private InputStream getFile(String File)
    {
        return getClass().getClassLoader().getResourceAsStream(File);
    }


Thanks for the help :D
