Hello Mxc forum,

 

In my attempt to correct l2jattackers and other packet flooding sh***s i tried to rework the mmocore, i didn't find the way so i made a code for packethandler debug,

Anyway here we are:

      Cruma - Lineage 2 World Viewer & Radar Map Generator

      By newrostman · Posted

      Update Oct 12, 2026   New - You can now view geodata on top of the game world and edit it.   Improvements - Screenshots (F12) now capture the window as you see it, with the interface, at full screen resolution. Shift+F12 takes a screenshot without the interface. In Options -> Interface you can choose which one F12 takes. Screenshots are saved to Pictures/Cruma/Screenshots, and each file is named with the date and time. After saving, a notice appears with a button that opens the folder.     Geodata   Geodata editing is experimental. Keep a copy of your geodata and pathnode files (if you plan to use the pathnode generator built into Cruma). The pathnode algorithm is restored from L2_TEST_LSERVER-r1.   What you can do - Open geodata. Use the Geodata tab on the right (G key) and choose a folder with *_conv.dat files (only the L2OFF format is supported). You can also set the path in the settings menu, with a separate folder for each client. - See geodata around the cursor: green is walkable, red is walls and closed sides. The radius is 2048 by default and can go up to 4096. X-ray (X) shows floors behind walls and under the ground. - Inspect cells. Click a cell to see its height, layers and open sides. Click again to go to the layer below (if there are several). You can show only one layer (Z) or only the area you can walk to from the cell (I). - Test routes. Drag the mouse from one cell to another to make a route from A to B. Modes: Path: finds the way like an L2OFF server does, with pathnode. Straight: walks in a straight line and shows where you get stuck. Sight: shows if A can see B (for skills and arrows). Reach: shows everywhere you can walk to from A. - Find problems. The Check tab checks an area for traps you can’t get out of, one-way passages and walls you can climb. Check results are hints, not exact errors. Some of these “problems” are normal in generated geodata. - Edit. Open and close cell sides (you can drag along a whole wall at once), paint Block, Open and Height with a brush or a rectangle and add or remove floors in a cell. Undo and redo are supported and changed cells are highlighted. - Save changes. Save straight into the geodata folder (with a backup), into a new folder, or as a small patch file with only your changes that you can load later. You can also rebuild pathnode at the same time. The panel shows where everything will be saved and you can choose the folder. A progress bar is shown while files are being written.   New version: 0.2.0 Previous version: 0.1.2
