Metin2 Beta and some differences compared to the early Release
The hand is there also Idk why but in the 2005 beta client u have plenty of texture for hairs and a new one for the warrior but the GR2 are missing or they were attached to the armor originally ? After watching this trailer for like 20 times, i just noticed that spider dungeon is really different, they used the seatou dungeon models with spider dungeon textures, maybe we can found it in the beta clients ? -

Metin2 remake on Unreal Engine 5
Hi ! I've been working for a while on a full Metin2 remake on Unreal Engine 5. The assets are imported from the 40250 source files from TMP4. After thinking a lot on it, I decided to make it open-source for science ! I hope some of you find this helpful and maybe collaborate on this. Everyone is free to make any pull requests. You can find all the details in the repository's README.md. https://github.com/iamBVC/UnrealLongju https://www.youtube.com/watch?v=4pBvP3xnJyA Cheers- 1

[C++] Fishing: forged casts accepted anywhere, a reload crash and fish consumed for nothing
Hi, While reworking fishing on our server we went through the stock fishing code (fishing.cpp, char.cpp, input_main.cpp) and found a few bugs. They're in the original game source, so most files should have them. Function names and lines can differ on yours: search for the snippets. 1. Core crash on boot or on /reload f If the last line of fishing.txt has no line break, strrchr returns NULL and the core writes to it. fishing.cpp, in Initialize(), search: char * p = strrchr(buf, '\n'); *p = '\0'; Replace with: char * p = strrchr(buf, '\n'); if (p) *p = '\0'; 2. FishingPractice uses the rod outside its NULL check fishing.cpp, at the end of FishingPractice(), search: rod->SetSocket(2, 0); } Replace with: if (rod) rod->SetSocket(2, 0); } 3. GetDesc() used without a check The fishing event and Take() send a packet with ch->GetDesc()->Packet(...). If the player disconnects at the wrong moment, that's a NULL dereference. In fishing.cpp, search both: ch->GetDesc()->Packet(&p, sizeof(TPacketGCFishing)); Replace each with: if (ch->GetDesc()) ch->GetDesc()->Packet(&p, sizeof(TPacketGCFishing)); 4. Fish consumed for nothing (UseFish / Grill) Both functions deduce the fishing.txt row from the item vnum by subtraction. If a fish item has no row of its own in your fishing.txt (in our files, 27824 to 27832 exist as items but have no row), the index lands on another row: the fish is consumed and the player gets nothing, or the wrong item. fishing.cpp, in UseFish(), search: if (idx<=1 || idx >= MAX_FISH) return; Add after it: // the vnum-based index must land on THIS fish's row if (fish_info[idx].vnum != item->GetVnum() || !fish_info[idx].dead_vnum) return; In Grill(), search: if (idx == -1) return; Add after it: // same guard: no row (grill_vnum = 0) means the fish was destroyed for nothing if ((fish_info[idx].vnum != vnum && fish_info[idx].dead_vnum != vnum) || !fish_info[idx].grill_vnum) return; 5. A forged fishing packet works anywhere On cast, the stock server only checks the player's own cell (not blocked), the rod and the bait. It even computes the point 4 m in front of the player and never uses it. So a forged HEADER_CG_FISHING fishes in town, in a corner, far from any water, dead or on a horse. The client checks for water before sending, the server never does. fishing.h, in namespace fishing, add: extern bool CanFishNow(LPCHARACTER ch); extern bool IsWaterInReach(LPCHARACTER ch); fishing.cpp, inside namespace fishing, add: bool CanFishNow(LPCHARACTER ch) { if (!ch) return false; // what the client blocks before sending, checked again here return !ch->IsDead() && !ch->IsStun() && !ch->IsObserverMode() && !ch->IsRiding(); } bool IsWaterInReach(LPCHARACTER ch) { // The client looks for water 600 units away in the direction it sends // (CInstanceBase::GetFishingRot). The angle arrives rounded to 5 degrees and the // server position can lag a little, so probe around that point. static const float s_afDistance[] = { 600.0f, 500.0f, 700.0f, 400.0f, 800.0f }; static const float s_afAngle[] = { 0.0f, -5.0f, 5.0f, -10.0f, 10.0f }; for (size_t a = 0; a < sizeof(s_afAngle) / sizeof(s_afAngle[0]); ++a) { for (size_t r = 0; r < sizeof(s_afDistance) / sizeof(s_afDistance[0]); ++r) { float fx, fy; GetDeltaByDegree(ch->GetRotation() + s_afAngle[a], s_afDistance[r], &fx, &fy); const long x = ch->GetX() + (long) fx; const long y = ch->GetY() + (long) fy; LPSECTREE tree = SECTREE_MANAGER::instance().Get(ch->GetMapIndex(), x, y); if (tree && tree->IsAttr(x, y, ATTR_WATER)) return true; } } return false; } char.cpp, in CHARACTER::fishing(), search: { LPSECTREE_MAP pkSectreeMap = SECTREE_MANAGER::instance().GetMap(GetMapIndex()); int x = GetX(); int y = GetY(); LPSECTREE tree = pkSectreeMap->Find(x, y); DWORD dwAttr = tree->GetAttribute(x, y); if (IS_SET(dwAttr, ATTR_BLOCK)) { Replace with: if (!fishing::CanFishNow(this)) return; { LPSECTREE_MAP pkSectreeMap = SECTREE_MANAGER::instance().GetMap(GetMapIndex()); if (!pkSectreeMap) return; int x = GetX(); int y = GetY(); LPSECTREE tree = pkSectreeMap->Find(x, y); if (!tree) return; DWORD dwAttr = tree->GetAttribute(x, y); if (IS_SET(dwAttr, ATTR_BLOCK) || !fishing::IsWaterInReach(this)) { We compared the server attributes with the client ones on 6 fishing maps: they differ on 63 cells out of about 7 million. We simulated 16,530 legitimate casts with the client's exact rule, and all 16,530 were accepted. 6. Negative cast angles arrive wrapped The client sends angle / 5 in a BYTE, and GetFishingRot can return negative angles (about 7% of legitimate casts in our test). They arrive wrapped (-20° becomes 252, i.e. 1260°), so other players see the fisher facing another way, and fix 5 would wrongly refuse those casts. input_main.cpp, in CInputMain::Fishing, search: ch->SetRotation(p->dir * 5); Replace with: // the same packet casts and pulls: only the cast carries an angle if (!ch->m_pkFishingEvent) { int iRot = (p->dir >= 128) ? ((int) p->dir - 256) * 5 : (int) p->dir * 5; iRot %= 360; if (iRot < 0) iRot += 360; ch->SetRotation((float) iRot); } If m_pkFishingEvent is private in your char.h, add a small getter instead. All of this is running on our server. If something doesn't match your files, tell me which part and I'll help.- 1

Insight Orb - Item Link Not Clickable in Main Chat
The PM window "fixing" it when it's behind the main chat is actually the key clue. In the stock client, hyperlink detection is global. While text is rendered, CGraphicTextInstance remembers the link that is under the cursor (Hyperlink_UpdateMousePos is called every frame from PythonApplication.cpp, and GrpTextInstance.cpp stores it). ui.GetHyperlink() / wndMgr.GetHyperlink() only returns that string. What changes is who handles the click: it's the Python window under the mouse. In a PM window, the whisper window's own OnMouseLeftButtonDown reads ui.GetHyperlink() and runs the link code. In the stock uichat.py, ChatWindow is only as tall as the input line (SetSize(CHAT_WINDOW_WIDTH, 25), 0 when the input is closed). The chat lines are drawn above it, outside its rect, so a click on a line goes to GameWindow in game.py (OnMouseLeftButtonUp, the hyperlink = ui.GetHyperlink() branch, which calls self.interface.MakeHyperlinkTooltip(hyperlink)). When you put a PM window behind the main chat, the whisper window becomes the window under the mouse, so its handler runs and the link works. So the Insight Orb part was most likely only added to the whisper window. Names can differ depending on your client, but check these three places: game.py → OnMouseLeftButtonUp: add the same Insight Orb handling you have in the whisper window (or make sure it reaches the same function). uiinterface.py → MakeHyperlinkTooltip: if the system handles its link type in a separate function that only the whisper window calls, route it from here too. For the hover tooltip in the main chat: whatever the whisper window does in its OnUpdate with ui.GetHyperlink() has to be added to GameWindow.OnUpdate as well. -

Metin2 on another game engine? UE5/Unity
I made this source code public. It's a remake of the game on Unreal Engine 5. The copyrighted Metin2 assets are not there, they are on a different repository, so this one can't be taken down by anyone. Check it if you want. It already works, there's just some missing features and items. https://github.com/iamBVC/UnrealLongju -

mob missing hit and delayed damage
1. Delete your data/monster folder. 2. Take your client files pertaining to npc,monster,monster2,npc_mount etc, and merge them into a simple /monster folder. If there's duplicates, keep the newest ones. 3. Remove the msm and dds, alongside the gr2 files. So leave just the motlist and animation files. 4. Paste the resulting folders in the now empty data/monster. 5. Compare each monster's folder field in proto with the one in npclist, relative to data. Profit. -
