ProtocolVersion packet is one of the first exchanges in the client-server handshake, and if the versions don't match, the server cannot correctly interpret the packet, leading to a buffer underflow. Since you're the only one trying to log in, the error likely means there's a version mismatch between your game client and the server. Even though it's just you on the server, if the client is not exactly aligned with what the server expects, it can still cause the server to misinterpret the data it receives, leading to that BufferUnderflowException error.

sounds like there are two different attack intentions, try to find the usages of the intention, keep in mind that isAttacking doesnt return the correct value in most cases so a quick approach for that is to get the AI of the attacker first

I agree with Baygus. The guy had absolutely no idea what he was asking for, which ended up being incredibly frustrating. I remember finishing some tasks related to the client, and this guy would just make shitcomments about how I was doing my job, all that because he didn't know how to apply the patch. It's like he was trying to prove that he was going dumber and dumber day by day, He didn't even bother to take a look at what the heck is inside this core side or client side. In short, a shitty experience.

for some weird reason //sethero is not enough to equip hero weapons, you have to be a hero from olympiad, i have managed to fix that weird problem in the past but i cant remember the solution of it

if (!target.getAggroList().isEmpty() && !target.getAggroList().containsKey(player)) continue;

based on Zake's reply, assume that the target is an instance of MonsterInstance so you can simply make a check like if (!target.getAggroList().isEmpty()) continue;

Assume that you already have made a new instance for your npc its simple onBypassFeedback you will add a check, like if (player.isVIP() && command.contains("tryme")) { player.getInventory().equipItemAndRecord(item); } then you will make an NpcHtmlMessage with a stringbuilder embedded and do smth like String button = "<button value=\"Give me the sauce\" action=\"bypass -h tryme\" width=\"50\" height=\"20\" back=\"L2UI_ct1.button_df\" fore=\"L2UI_ct1.button_df\">"; htmContent = htmContent.replace("%buttonTryMe%", button); as you can see above in the first example i made a check to handle the action of the button, in the second example we just simply create the button, hope you find it helpful

what you did right now is to move weapon map outside your main method, why to do that?

You can do it by moding the client either by implementing a part of code in your server side(sending any type of msg on player with the augmentation info)

You have to simply create an npc instance which handles this type of request, by reviewing similar codes you can easily understand what you have to do. Remember your class should extend Npc mother class so you can implement such methods like bypassFeedback

That should be inside CharInfo with no doubt

Its 15 vs 7 its not a draw mxc should be clearly specialized on l2
