OpenDAoC-BuildNav

A fork of the buildnav tool from the uthgard-opensource repository, originally created by thekroko.

Prerequisites

1. 64-bit Environment: All components must be built and run as 64-bit.
2. GameServer DLL: This project references GameServer.dll from the main OpenDAoC-Core project to use its LocalPathingMgr. Copy the resulting 64-bit into this project's base directory.
3. Detour DLL: Build Detour.dll from the OpenDAoC-Core Detour project. Copy the resulting 64-bit into this project's base directory.

How it works

1. The tool reads game asset files from DAoC’s zones folder.
2. The processed data is fed into RecastDemo.exe to generate initial navigation meshes.
3. The final navigation meshes (*.nav) are used by the game server.

Recast integration

Recast is included as a precompiled executable in the base directory.

This RecastDemo.exe is a repurposed 64-bit build of the official RecastDemo, slightly tweaked to accept command-line arguments and handle large worlds. Parameters for navmesh generation (agent size, etc.) are currently hardcoded and not configurable.

It can also be used to manually inspect the generated meshes:

1. Open RecastDemo.exe from the output directory.
2. Select "Tile Mesh" as the sample.
3. Select any generated *.gset as the input mesh.
4. The corresponding *.nav file will also be loaded for inspection.

Usage instructions

1. Build and run buildnav.exe --daoc=<gamedir>. Use either --all=true, or --zones="id1,id2..." and/or --regions="id1,id2...".
2. Copy the generated *.nav files from the output directory into your server's /pathing directory.
