Hello,
I am having an exception coming from the RVO system. It doesn’t occur 100% of the time but it does occur across PC/Mac Editors and on various devices.
System.IndexOutOfRangeException: Invalid allocation -2
This occurs when I am placing an obstacle in the game. I make a call to AstarPath.active.UpdateGraphs with a bounds surrounding my obstacle so I can set certain nodes on the graph as unwalkable.
I have an RVOSimulator in my scene and a handful of RVOAgents.
Am I using something incorrectly, or is there a way to workaround this issue? Happy to share more information.
It is Unity 2022.3.21f1, Package version 5.0.3. I am using 1 Grid Graph.
Here is the full trace from the exception:
System.IndexOutOfRangeException: Invalid allocation -2
This Exception was thrown from a job compiled with Burst, which has limited exception support.
