Improvement: tile update with new geometry #236

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
what should be the best way to completely rebuild tile with new geometry?

as I understand,  mesh generation  needs single source mesh to build all tiles 
for navigation. I tried to modify source code of Sample_TileMesh to build every 
tile from separate geometry, but it's ended in separate islands of navigation 
meshes (one non connected island for every tile). Seems like connection 
information are extracted from source mesh (portals?)

You rebuild meshes the same way you build them in the first place. Each tile 
needs a bit more geometry outside the tile tool. Look carefully how the 
geometry query bounding box is expanded in the example code. If a recast tile 
matches some tile in your game world, you will need to feed in all the 8 
neighbour tile geometry too when building the center tile.
