Need to load the last present record from a sequence of loaded records. That
means reverse should be called before unique or unique should be applied for
a reversed range. Since unique keeps only the first element from a sub
sequence of equal elements.
Use forEachUnique with reversed range to avoid redundant container
modifications.
Use "pragma max_page_count" to define max allowed file size in combination with
"pragma page_size" based on a new setting "max navmeshdb file size".
* Stop navmeshtool on the first db error.
* Disable writes to db in the engine on first "database or disk is full"
SQLite3 error. There is no special error code for this error.
* Change default "write to navmeshdb" to true.
* Use time intervals for transaction duration instead of number of changes.
* Remove tiles outside processing range. Useful when new content profile map
has different bounds.
* Remove ignored tiles. For a case when content profile maps have intersection
but there is no more data for navmesh.
* Remove older tiles at the same worldspace position. If navmesh tile data has
changed with new content, the old ones unlikely to be used.
* Vacuum the database when there are modifications. SQLite leaves empty pages
in the file on database modification. Vacuum cleans up unused pages reducing
the file size.
If object is too big iteration over all tiles covering it can take too much
time. Limit bounds to a square around a player position to cover only tiles
that will be present in navmesh based on max tiles number option.
Each object is associated with a set of tiles its present in. Culling can
reduce this set but it has to be update when bounds change position. Do this
in TileCachedRecastMeshManager::setBounds updating the set and adding/removing
objects to the corresponding CachedRecastMeshManagers.
* Avoid inheritance.
* Define equality operators out of the class definition.
* Replace toString with toStringView where it doesn't make sense to create a string.
