Cylinder collision shape should give the best consistency between physics
simulation and pathfinding. Rotating box is already used by some actors, so
add it to have the same collision shape type for all actors.
Actors may have different collision shapes. Currently there are axis-aligned
bounding boxes and rotating bounding boxes. With AABB it's required to use
bounding cylinder for navmesh agent to avoid providing paths where actor can't
pass. But for rotating bounding boxes cylinder with diameter equal to the front
face width should be used to not reduce of available paths. For example rats
have rotating bounding box as collision shape because of the difference between
front and side faces width.
* Add agent bounds to navmesh tile db cache key. This is required to distinguish
tiles for agents with different bounds.
* Increase navmesh version because navmesh tile db cache key and data has changed.
* Move navmesh version to the code to avoid misconfiguration by users.
* Fix all places where wrong half extents were used for pathfinding.
Use LRU cache for ESMReaders. When cache capacity is reached close least
recently used ESMReader. Remember the file name if a reader was open. Once the
reader requested again open the file if there is stored name for it. Put
released ESMReader to the back of the free items list. Close ESMReader's from
the front of the free items list.
Cached item can be used only by one client at the same time. If the same item is
requested twice exception is thrown. This should never happen in practice. If
this happens need to fix the client logic.
It's allowed to go over the capacity limit when requesting different readers.
Ideally this should never happen but there will be system error anyway
signalizing about too many open files. Need to fix client logic in this case.
All places that were using a vector of ESMReaders now using the cache. Cache is
local for each use case and there is no need for a thread safety.
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.
