I recently got a bug report from Hyper regarding my spinner class where it had crashed during state hunting.

I went over the script and dont see any problems (well obvious ones). The spinners state hunting is more or less the same as scriptedpawns code anyway.

The spinner crashed while calling FindPathToward() .

I searched the forums here and found an identical crash from the gasbag during victory dance.

Are you able to shed any light on this smirtsch? as to what might be causing this? I believe its an engine crash but why not all the time? Under what circumstances might it crash?

Both logs below

Cheers

outgoing from these logs i can give no explanation for it either- i have some idea's, but can only tell if i can reproduce this error

You may want to look at what its Target variable is set to at the crash time. I have noticed that if Target is set to none or if it is pointing to something that is about to be destroyed that you get flaky operation that can lead to crashes.

If it is what's referenced to Target causing the problem then it being 'None' doesn't seem to be the cause. The ScriptedPawn.VictoryDance state has a check when Target is none where the function is used and there still was that crash.

Code: Select all

function PickDestination()
{
      local Actor path;
      local vector destpoint;
            
      if (Target == None)
      {
            WhatToDoNext('Waiting', 'TurnFromWall'); 
            return;
      }
                .
                .
                .

Maybe the object referenced to Target is flagged 'bDeleteMe' just before, but I don't think that's it either.

The FindRandomDest() crash can occur in illhaven_3 too. Perhaps there is a similarity to what causes the processes of that function to crash, and what's happening with FindPathToward(). The illhaven_3 map could be used for trying to reproduce this crash. A buggy map must have an effect with this just as it does with FindRandomDest().

I had this problem with 1 my map a while ago, when I looked in editor at the paths.. 1 path went though half of the map (walls and everything) by some unknown reason. I simply just defined paths again and problem was solved.

The spinner checks actor none and bdeleteme in its state hunting so thats not its prob. I even set playerpawn to bdeleteme during a game while it was hunting me and no crash.

It may not be that hard to see if the pathing is causing probs (in this case) as the only place in eldora that has gasbags is at the end of the level. (or check with editor) and that part of the level is tiny.

Maybe its prossible to replicate the crash by making a slow moving gasbag that you summon behind the big rock in that level and then run the opposite side of the rock or down the well etc causing the gasbag to go hunting. (havent tried it yet). Might take a lot of attempts tho, until it choose the crashing path.

What does breadthPathFrom do? Does it for example call the trace function to see if the paths are clear?
