[IndexOutOfRangeException] RecastTileUpdateHandler

General Recast graph
#1

The RecastTileUpdateHandler throws an IndexOutOfRangeException. We’ve pulled the script from the Example Scripts to update our Recast Graph.

[Exception] IndexOutOfRangeException: Index was outside the bounds of the array.
RecastTileUpdateHandler.ScheduleUpdate()    Assets/Scripts/Systems/EmergencyExit/RecastTileUpdateHandler.cs:107
105:   for (int z = touching.ymin; z <= touching.ymax; z++) {
106:       for (int x = touching.xmin; x <= touching.xmax; x++) {
-->107:           dirtyTiles[z*graph.tileXCount + x] = true;
108:       }
109:   }

57:       }

Hi

It looks like you have made some heavy modifications to that script. The original script doesn’t even have a ScheduleUpdate method, nor is any callback named OnNeedUpdates called.

I’m going to forward that to my collegue :slight_smile:

Hi!

Almost nothing of this script has been modified afaik.
Here’s the link to your script: https://arongranberg.com/astar/docs/class_pathfinding_1_1_recast_tile_update.php

It appears the methods are the same. :slight_smile:

Ah. I misread the script name.

Hm… Are you re-scanning/changing the dimensions of the graph during runtime by any chance?

#6

We are creating all graphs during runtime and are scanning during runtime. All our graphs work on dynamically created and/or loaded scenes. Once a graph is created we are not changing it’s dimensions on purpose - does it do that during a scan?. We are creating additional Recast Graphs to operate on.

#7

Try to log

Debug.Log(touching + " " + graph.tileXCount + " " + tileZCount + " " + dirtyTiles.Length);

right after the

var touching = graph.GetTouchingTiles(bounds);
