Syntax

dtStatus findRandomPointAroundCircle
(
    dtPolyRef startRef,
    const float * centerPos,

    const dtQueryFilter * filter,
    float(*)() frand,

) const

Remarks

Returns random location on navmesh within the reach of specified location. Polygons are chosen weighted by area. The search runs in linear related to number of polygon. The location is not exactly constrained by the circle, but it limits the visited polygons.

Returns

The status flags for the query.

Parameters

Parameter	Description
startRef	The reference id of the polygon where the search starts.
centerPos	The center of the search circle. [(x, y, z)]
filter	The polygon filter to apply to the query.
frand	Function returning a random number [0..1).
randomRef	The reference id of the random location.
randomPt	The random location. [(x, y, z)]
