Question

Posted (edited)

Anyone can help me edit a jar file?

I am trying to edit a jar file, i added jar in intellij, opened the gameserver.class which i want to edit, i have made a copy and saved as java and i cannot build it because it show lots of errors.

I started to belive my PC windows is broken and I have to reinstall it. I need to know if I have to reinstall my OS or I am too tired and I make little mistakes, this is driving me crazy...

PS: This should work 100% as the author of the guide say, I am using this guide here:

If you want just to edit some strings, theres a way:

But if you want to rebuild decompiled jar then its complicated because you will have to reverse engineer everything yourself.

Is strange because i follow the video exactly, with all details and not work for me. I have tryed with different jars and nothing, same errors. I ask for help because I need to know 100% if I do some mistakes or my PC windows OS is broken... I already repeat the same thing even following a tutorial video because i was thinking I do things wrong.

Edited the file, but won't share how he did it. Also the file is full of errors and bad edits... Thanks for your effort anyway.

    • Thank you for the reply. I know that this issue is due to L2 being so old. I was just wondering if there was an external way to fix the UI scaling. Like a patch or some settings.
    • Bro the game is so old it doesn't have a native option to scale the UI like in modern MMOs
