Syntax

bool isValid
(
    const int maxLookAhead,
    dtNavMeshQuery * navquery,
    const dtQueryFilter * filter
)

Remarks

Checks the current corridor path to see if its polygon references remain valid.

The path can be invalidated if there are structural changes to the underlying navigation mesh, or the state of a polygon within the path changes resulting in it being filtered out. (E.g. An exclusion or inclusion flag changes.)

Parameters

Parameter	Description
maxLookAhead	The number of polygons from the beginning of the corridor to search.
navquery	The query object used to build the corridor.
filter	The filter to apply to the operation.
