perf: Add path height correction on world load (#1178)
* Add path height correction on world load * Increase height because Nexus Tower is tall * Update height checker - Only go up and down, do not deviate from the point you are on - As a backup, use the nearestPoint on the nearestPoly, should detour be able to find one. - Add a debug assert to fail the program should toReturn differ from nearestPoint[1]. Update dNavMesh.cpp Update dNavMesh.cpp * Fix if condition to actually return the value... --------- Co-authored-by: Aaron Kimbrell <aronwk.aaron@gmail.com>
