The pathfinder was pushing locations with negative coordinates (or
coordinates larger than the map size) onto the queue, which led to
memory corruption in CAStarEngine's node array and later a crash in its
destructor.
This was SVN commit r3923.
- Pulled out the A* implementation to a separate class to support reuse
of code for the high level pathfinder
- Cached the the open/closed status of nodes to improve speed
- Added a maximum node limit before the search is cut off
(DEFAULT_SEARCH_LIMIT in AStarEngine.cpp for now)
- Allied unit collisions are now ignored
This was SVN commit r3861.
