IndexOutOfRangeException for RecastGraph with RichAI enemy

General Recast graph
1

Hi,

I am getting a IndexOutOfRangeException: Array index is out of range. Exception. This is my scene:

  • A* Pro v 3.7.4
  • An enemy with RichAI script to search for the player.
  • Player moves and adds objects on screen rapidly. Every 0.25 sec I call the UpdateGraph with the added object’s bounds.

The graph is a RecastGraph, about 100x100 (tile size 5, cell size 1). No penalty zones.
After a while I get:

IndexOutOfRangeException: Array index is out of range.
Pathfinding.RecastGraph+NavmeshTile.GetVertex (Int32 index) (at Assets/AstarPathfindingProject/Generators/RecastGenerator.cs:369)

Pathfinding.RichAI.Update () (at Assets/AstarPathfindingProject/Core/AI/RichAI.cs:305)

Please help me understand.

Thanks,
Guy

Hm… That’s odd.
Would it be possible for you to send a reproducible example scene?
