A C# app to help make building NavMeshes for FFXI faster using collision data.

here is a quick demo on what to do. https://www.youtube.com/playlist?list=PLsww_EXH6VoprH94s967sgt_RM4ENYmb0

• Dump zone collision data to obj files.
• Build navmeshes using FFXINAV.dll

• float m_tileSize = 256;
• float m_cellSize = 0.40f;
• float m_cellHeight = 0.20f;
• float m_agentHeight = 1.8f;
• float m_agentRadius = 0.3f;
• float m_agentMaxClimb = 0.5f;
• float m_agentMaxSlope = 46.0f;
• float m_regionMinSize = 8;
• float m_regionMergeSize = 20;
• float m_edgeMaxLen = 12.0f;
• float m_edgeMaxError = 1.3f;
• float m_vertsPerPoly = 6.0f;
• float m_detailSampleDist = 6.0f;
• float m_detailSampleMaxError = 1.0f;

• float m_tileSize = 64; <<<< this can be changed for small zones.
• float m_cellSize = 0.20f;
• float m_cellHeight = 0.010f;
• float m_agentHeight = 1.8f;
• float m_agentRadius = 0.7f; <<<< if you make this too big it will break the mesh. 0.7f has been tested on most zones.
• float m_agentMaxClimb = 0.5f; <<<< this might need changing for some zones. max climb changes from 0.3f to 0.5f, trial and error
• float m_agentMaxSlope = 46.0f;
• float m_regionMinSize = 8;
• float m_regionMergeSize = 20;
• float m_edgeMaxLen = 12.0f;
• float m_edgeMaxError = 1.3f;
• float m_vertsPerPoly = 6.0f;
• float m_detailSampleDist = 6.0f;
• float m_detailSampleMaxError = 1.0f;

• The DarkStar project / Topaz team for providing invaluable insight into the underlying workings of the game.

Collision obj files can be found in here - Map Collision obj files folder. NavMeshes can be found in here - Dumped NavMeshes folder.

Here you can dump the zone collision data to obj files,

this zone dat list is provided by Devi Ltti (Thanks Devi).

• Select ZoneList.xml. This will add all the Zones to the ListBox.

2. Select the zone you want to build the collision OBJ file for.

2.1. Click to Build Selected Zone OBJ file.

3. Click this if you want to Build "All" collision OBJ file for current List.

Some Zones (Airships) take a while to dump the obj files.

here you can build navmeshes using FFXINAV.dll

1. These settings are the "Default settings Topaz NavMeshes are made with. Changes to these settings will affect performance on the server.

2. Click this to set up the DLL's Settings you must do this first before you start dumping meshes.

3. Click this to Select a OBJ file to build a NavMesh for.

4. Click this to start orstop building NavMeshes for all OBJ files in the Map Collision obj files folder.

When you click stop it will finish the Current NavMesh build.

 *  1. Place the zone.obj file in  RecastDemo/Meshes/.
 *  2. Place the navmesh.nav in the same folder as RecastDemo.exe "RecastDemo".
 *  3. Rename "navmesh.nav" to "all_tiles_navmesh.bin".
 *  4. Open RecastDemo.exe-> on the right hand side click -> choose sample -> Tile Mesh.
       Iput Mesh -> select the .obj file you want to edit.
 *  5. Once the .obj is loaded on screen -> scroll down and click load. you will see the mesh load on screen as "blue".
       This might take a long time depending on the size of the zone.
 *  6. To remove tiles, on the left hand side click "Create Tiles" then on the mesh click Shift+ left mouse button.
 *  7. To rebuild the tile click on the part of the mesh with left mouse button.
 *  8. You can create off-mesh links with the tool on the left hand side. 
       once you have added all your off-mesh links you then need to click "Create Tiles" and "Build all Tiles".
 *  9. When you are finished click save from the tool menu on the right hand side.
 *  10.It will save as "all_tiles_navmesh.bin" you will need to rename this to "ZoneName.nav".   

• you may need to edit zonelist.xml and change the path to where you have final fantasy xi installed.

• If this happens, you can open the obj file in blender and delete the door, or you can open the obj and navmesh in recastdemo and add an offmesh links.

• CanSeeDestination.
• Unload.
• Initialize // needs path to log config file (Default_Config.conf which is included).
• Load // loads the navmesh.
• LoadOBJFile.
• DumpNavMesh.
• GetLogMessage.
• FindPath.
• FindRandomPath.
• FindClosestPath. // this prevents exploits with navmesh / impassible terrain
• IsValidPosition. // can be used to make a grid for A star pathfinding. (if you didn't want to use recast detour to find a path).
• GetDistanceToWall. //this is distance to navmesh edge
• GetRotation.
• IsNavMeshEnabled.
• PathPoints.
• NavMeshSettings. //Lets you change the NavMesh settings before building a new mesh
• GetWaypoints. //returns the waypoints in the path
