Generates preprocess data for pathfinding around agent unobstructed space.


void generatePathfindPreprocessFor(const iShape& shape, const char *const* options);


shape The shape for which pathfind preprocess should be generated.

This parameter enables optional attributes to be passed in to control aspects of the preprocess generation, if special behaviour is desired.

If special bevaviour is desired, then see Handling Attributes for general information about passing attributes, and Pathfind Preprocess Generation Attributes for a list of the attributes that can be passed in specifically to this method.

See Handling Attributes for general information about passing attributes.

If no special behaviour is desired then you can just pass zero in for this parameter, to indicate no attributes.


Unobstructed space must be present for the shape on this mesh, and must be 'combined' (i.e. the 'combine' argument should have been set to true when generating unobstructed space).

Pathfind preprocess must not already be present for the shape on this mesh.


You can avoid the overhead of generating preprocess at runtime by using iMesh::savePathfindPreprocessFor() and iMesh::loadPathfindPreprocessFor() to save and load the data to and from a persistent store.

Multithreading details: Base mesh preprocess generation operations are non-blocking between shapes, so preprocess can be generated for multiple shapes simultaneously.
(See Using PathEngine with Multithreaded Applications.)
