Summary

Function: llGetClosestNavPoint( vector point, list options );

The function accepts a point in region-local space (like all the other pathfinding methods) and returns either an empty list or a list containing a single vector which is the closest point on the navmesh to the point provided.

• vector point A point in region-local space.
• list options No options at this time.

Options V Parameters Default Description
GCNP_RADIUS ] 0 float distance ] 20.0 ] Limits how far out to search for a navigation point.
GCNP_STATIC ] 1 integer use_static_mesh ] FALSE ] Specifies whether the test should use the static or dynamic nav mesh. In the static case, all dynamic obstacles are ignored.
CHARACTER_TYPE ] 6 integer type ] CHARACTER_TYPE_NONE ] Filters nav points by eliminating nav mesh faces which are 0% walkable for the specified character type. In the default CHARACTER_TYPE_NONE case, all nav mesh faces are included.

Caveats

  • This function causes the script to sleep for 1 frame.
  • There is no guarantee that a path exists from your current location to the returned point.

Notes

Using the method incurs a one frame script sleep and the call can be extremely expensive. It is intended to be used in response to a path_update message indicating an inability to reach a requested destination (e.g., because the character or the destination is off the mesh).
