2d coord hash moved to hash.hpp file
format version adds suffix to be more coherent
don't use ESM::RefId::sEmpty
RefId equality with string_view, conversion to refId unecessary
action teleport remove test that mCellId is empty
removes some const references, when copy is enough
invalid refid => empty refid
removes useless change
The strong type is actually just a string underneath, but this will help in the future to have a distinction so it's easier to search and replace when we use an integer ID
Slowly going through all the changes to make, still hundreds of errors
a lot of functions/structures use std::string or stringview to designate an ID. So it takes time
Continues slowly replacing ids. There are technically more and more compilation errors
I have good hope that there is a point where the amount of errors will dramatically go down as all the main functions use the ESM::RefId type
Continue moving forward, changes to the stores
slowly moving along
Starting to see the fruit of those changes.
still many many error, but more and more Irun into a situation where a function is sandwiched between two functions that use the RefId type.
More replacements. Things are starting to get easier
I can see more and more often the issue is that the function is awaiting a RefId, but is given a string
there is less need to go down functions and to fix a long list of them.
Still moving forward, and for the first time error count is going down!
Good pace, not sure about topics though, mId and mName are actually the same thing and are used interchangeably
Cells are back to using string for the name, haven't fixed everything yet. Many other changes
Under the bar of 400 compilation errors.
more good progress <100 compile errors!
More progress
Game settings store can use string for find, it was a bit absurd how every use of it required to create refId from string
some more progress on other fronts
Mostly game settings clean
one error opened a lot of other errors. Down to 18, but more will prbably appear
only link errors left??
Fixed link errors
OpenMW compiles, and launches, with some issues, but still!
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.
That are based on half extents used to find path over navmesh which is different
for interior and exterior cells.
Use common functions to get agent height and radius for actor path rendering and
navmesh generation.
Recastnavigation uses path cost and heuristic based on distance to find
shortest path by A* algorithm. Using raw speed values makes cost much lower
value than heuristic (1000 times less at maximum). Heuristic is defined as
distance from node to target * 0.999 that means area cost should never be less
than 0.999 or 1 for simplicity.
Use max speed to make lowest possible cost factor equal to 1.
Even when target is not reachable actor will try to run there either because
target navmesh polygon is selected within extended area or because partial path
is built to the closest possible polygon.
Actor may reach destination before collision. Get next path point from active
packet pathfinder and use point tolerance to reduce distance.
Use maximum of last destination tolerance and DEFAULT_TOLERANCE because
there are 2 checks made for path completion. First checks whether actor is
close enough to the destination and second drop last path point when actor is
closer than DEFAULT_TOLERANCE.
Division by zero causes float value to be infinite. When infinite cost is
multiplied by zero distance the result is NaN. After this pathfinding algorithm
state is broken.
When distance between start and end point is greater than max radius of area
possibly covered by navmesh there is no way to find path via navmesh. Also if
distance is greater than cell size navmesh might not exists withing mentioned
area because cell is not loaded therefore navmesh is not generated. So minumum
of these values is used to limit max path distance. Assuming that path
actually exists it's possible to build path to the edge of a circle. When
actor reaches initial edge path is built further. However it will not be
optimal.
This allows to distribute AI reaction calls over time.
Before this change actors appearing at the same frame will react in the same
frame over and over because AI reaction period is constant. It creates a
non-uniform CPU usage over frames. If a single frame has too many AI reactions
it may cause stuttering when there are too many actors on a scene for current
system.
Another concern is a synchronization of actions between creatures and NPC.
They start to go or hit at the same frame that is unnatural.
