    Implementing PKGNX..

    Hello, so I`ve been wanting to implement and use NX files instead of my WZ, so I`ve been trying to get that to work. Lithium takes forever to load and I`m hoping this would help. Anyways my problem is that when I changed the .wz files in certain directories such as MapleLifeFactory.java, to .nx, I`ve been getting this error about:
    PHP Code:
    SERVER: Failed to load UTF in buffer 
    Anyways here is the full error, and yes I have all the files implemented in the source, and the NX folder in my source.
    PHP Code:

    Login Server failed java.lang.NullPointerException
    Press any key to     continue . . . 
    I've added the usage of NX files for everything that to the instances that use WZ in start.java
    Thanks for the reading .

    Also here is my getUTFString() in SeekableLittleEndianAccessor:
    PHP Code:
        public String getUTFString(int length) {        try {
                    byte[] data = getBytes(length);
                return     utfDecoder.decode(ByteBuffer.wrap(data).order(ByteOrder.LITTLE_ENDIAN)).toString();
            } catch (    CharacterCodingException e) {
                    logger.error("Failed to load UTF String in buffer.", e);
            }
            return     null;
        }

    Re: Implementing PKGNX..

    Clearly there is an invalid utf-8 string in the NX file, which leads me to ask how you obtained the NX files.
    To be more helpful, can you print out the raw bytes in hex format when that error occurs?

    Your code is fine, its just the NX file itself which is slightly broken.

    Well It was v145 converted files that a friend gave me. I'm not sure if anything of this version is released :O
    Also where do you want to me to inprint the the bytes?

    Re: Implementing PKGNX..

    Just print it out right in that catch thing, so when the error occurs it prints out the bytes.

    Re: Implementing PKGNX..

    I'm having trouble printing out bytes, since the function getUTF is in string.

    - - - Updated - - -

    I also tried to print toString() which didnt give any bytes.

    Re: Implementing PKGNX..

    I just added special code to NoLifeWzToNx to detect ansi strings which are not utf-8 compatible and automatically convert them to proper utf-8, which should fix your issue.
    You can convert the WZ files yourself using NoLifeWzToNx (prebuilt binary here: https://dl.dropboxusercontent.com/u/...NoLifeStory.7z)
    Or you can use my freshly converted GMS v145 NX files: https://mega.co.nz/#!pNtlXIqQ!JOJX_G...JQv13c7UHaQ540

    Re: Implementing PKGNX..

    Thanks, your version seems to be avoiding the previous error, but once I changed codes like these:
    PHP Code:
     final MapleDataProvider prov = MapleDataProviderFactory.getDataProvider(new File(WZpath + "/Etc.wz")); 
    From .wz to .nx, I get:
    PHP Code:
    Login Server failed: java.lang.NullPointerExpection 
    My start server reaches until here before it throws the error:
    PHP Code:
            MapleLifeFactory.loadQuestCounts();       
               MapleQuest.initQuests(); 
               MapleItemInformationProvider.getInstance().runEtc(); 
               MapleMonsterInformationProvider.getInstance().load(); 
    The only thing that was edited in those files should be changing the .wz to nx.
