Another IndexOutOfRangeException when loading prefab with FSM
« on: October 07, 2022, 08:43:00 PM »
Similar to the previously posted bug, I'm making a new thread as it looks like our callstack is slightly different.  We always get around 20 of these on startup and I don't think we are seeing any incorrect behaviour, but I would like to clean up the errors before upgrading to 1.9 in case there is some deeper problem.

This is a the callstack
Code: [Select]
Error Loading Action: restart : HutongGames.PlayMaker.Actions.CollisionEvent : gameObject
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
  at System.Collections.Generic.List`1[T].get_Item (System.Int32 index) [0x00009] in <6073cf49ed704e958b8a66d540dea948>:0

UnityEngine.Object:Instantiate<UnityEngine.GameObject> (UnityEngine.GameObject)


Unfortunately I can't set a breakpoint to see which fsm or state is going wrong, if I could even get that information I might be able to clean it up.

Hi.
The action "restart" is this a custom action from the ecosystem or from a 3rd party asset?

i think restart is the name of the state, and the action is after that, for example we also get these others:

Code: [Select]
Error Loading Action: restart : HutongGames.PlayMaker.Actions.FloatCompare : equal
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Error Loading Action: restart : HutongGames.PlayMaker.Actions.FloatCompare : lessThan
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Error Loading Action: restart : HutongGames.PlayMaker.Actions.SendEvent : everyFrame
System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Unfortunately we have many nested prefabs so I can't find the restart state to try and figure out what is wrong with it, is there a way to find a state by name? Or if the error handler could print the name of the fsm that would also be really helpful.
