Returns an index for the connected region at a given position. This can be used to quickly determine the reachability between positions.
int32_t getConnectedRegionFor(const iShape& shape, const cPosition& p) const;
|shape||The agent shape for which connected region preprocess should be queried.|
|p||The position to test.|
Requires that this obstacle set has been marked for preprocessing, with connected region queries support.
A position is reachable from another position if both positions are unobstructed and this query returns the same connected region indices for both positions.
If called with an obstructed position, this method will return -1.
This method enables you to query against the set of 'semi-dynamic' obstacles
in a 'preprocessed obstacle set', in addition to static geometry.
For queries against just the static geometry on this mesh (i.e. external edges and burnt in obstacles), use
int getConnectedRegionFor(Shape shape, PathEngine.Position p);
