This header allows us to properly switch between experimental/finished STD implementations without having to adjust the source code (required for compiling on older versions of the Visual Studio 2017 compiler).
* dtIntersectSegSeg2D: Calculate over zy-plane instead.
* dtOverlapPolyPoly2D: Calculate over zy-plane instead.
* dtNavMeshQuery::findRandomPoint: z = h.
* dtNavMeshQuery::raycast: Invert hit normals.
* Update all comments to use xyz vector instead (previously xzy (xz-plane z-height)).
This increases the size of the path lines (this had to be increased due to the scale of the maps in this engine, recast was originally not scaled for it).
* Removed Samples button and dialogue.
* Removed SoloMesh.
* Removed TempObstacles.
* Limit 'Verts Per Poly' to 6 (DT_VERTS_PER_POLYGON).
* Moved hulldef constant and handler to TileMesh.
* Set m_tileSize based on hull (small = 32, med_short = 32, medium = 32, large = 64, extra_large = 64).
* Add missing dtQueryFilter field (some flag used in the engine but not sure yet what it does).
* Set tile->polysEnd and tile->offMeshConsEnd to end of polys and offMeshCons array pointer (if ever needed).
* Set camera perspective to 75 (previous 50).
* Improve theme.
* Lowered the climb height for all hulls (this improves NavMesh generation around low obstacles, previously it would create a poly connecting the ground on the side with the surface of the object around where it connects with the ground, causing AI to take this route instead and kind of 'glitch' onto the surface).
* Set reachability table count to 1.
* Don't divide reachability write size by 4.
* Trim off all unused bytes after building reachability table.
* Default cvar 'navmesh_always_reachable' to 0.
AI behavior seems to have improved a bit, they attempt to pathfind better, and if they find a certain route they attempt another route where originally they would become stuck in such situation.
If you build the SDK after this commit, you need to rebuild all navmeshes, else the game would segfault in dtNavMesh::isPolyReachable().
