Game Crashes When Certain Unit Dies

[fr0ggE]

I have an "Escort the Caravan" style Quest at the beginning of my map. There is a "Caravan Leader" who is involved in several triggers.

When the Caravan Leader dies, the game usually crashes between 5 seconds and a minute later. I figure that somewhere some trigger is running and asking him to do something, and because he is dead, the game crashes.

I tried destroying all the triggers that could do that when he dies, but the game still crashes.

I tried creating another "Caravan Leader" out of the way somewhere, and rebinding the variable, so that when random triggers run and ask him to do something he still can. It still crashes.

Here are some excerpts from the "Crash Report", which I don't know how to parse.

Thanks in advance for any suggestions!

Remake the unit? Try that.

 

[fr0ggE]

I did remake the unit.

It's possible the crash is from something else. I just noticed that every time he dies, the game crashes, but if you protect him the whole way there will usually (not always) be no crashes.

Is it possible to tell from the Error Report which trigger is causing the crash?

 

[fr0ggE]

What is the best method for figuring out what is causing your crashes?

Thanks for the help.

 

[cleeezzz]

so you have no triggers with the event " A Unit Dies "?

 

[fr0ggE]

I do have such a trigger.

I've also added a new condition to many of the triggers using him "Caravan_Leader_Alive = True" which gets set false when he dies.

• Caravan Leader Dies
  • Events
    • Unit - A unit Dies
  • Conditions
    • (Dying unit) Equal to Caravan_Leader
  • Actions
    • Set Caravan_Leader_Alive = False
    • Trigger - Turn off (This trigger)
    • Trigger - Turn off Caravan Close Enough <gen>
    • Trigger - Turn off Caravan Movement <gen>
    • Trigger - Turn off Ambush is Defeated <gen>
    • Trigger - Turn off Replace or Ice Prison on Leader <gen>
    • Trigger - Turn off Replace Ice Prison Timer Expires <gen>
    • Trigger - Turn off Life of Caravan Leader gets too low <gen>
    • Quest - Mark Quest_EscortCaravan as Failed
    • Quest - Display to (All players) the Quest Update message: Escort the Caravan ...
    • Unit - Create 1 Caravan Leader for Neutral Passive at (Center of Hero Select <gen>) facing Default building facing degrees
    • Set Caravan_Leader = (Last created unit)
    • Set LeadWagon = Artane
    • Wait 1.00 seconds
    • Unit - Order FollowWagon to Follow LeadWagon
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (FigurineOfPower_CaravanLeader is alive) Equal to True
      • Then - Actions
        • Unit - Kill FigurineOfPower_CaravanLeader
      • Else - Actions

 

[fr0ggE]

Would it help if I posted all my triggers relating to this unit? (There are 16 of them, but a few are definitely not the problem)

Thanks.

hmm... this seems to be useful.. maybe?

maybe inside a loop? there;s an error...
you ommited some in the error message. maybe the full thing will help.

 

[fr0ggE]

OK, I've found a likely culprit. I added a Game Display Text to the beginning of all likely triggers and played. Everything was running at the right time, but when I killed the Caravan Leader, after a while this trigger started running in an infinite loop. What happened was, the "Caravan_Visibility_Unit" (an invisible unit that lets a chain lightning guy have vision to blink in and cast CL) who had been following the Caravan Leader, I had never reordered to follow the "LeadWagon" (which is the new leader).

However, sometimes the game crashes instantly upon the leader's death, and sometimes it goes for a while. In the test game I played, even after the infinite loop began, the game did not crash right away, so I wonder if this is just one crash of several. TT

Thanks for the help. I'll let you know if it keeps crashing after adding a

"Order Bandit_Vision_Unit to Follow Lead_Wagon"

to the else clause at the end

 

[Zanderist]

How did you get a crash report?

 

[Sessional]

Looks like that error type is common in more then just wc3.

I just googled the EXC_CRASH (SIGILL)

http://forums.warhammeronline.com/warhammer/board/message?board.id=bug_mac&message.id=758
warhammer had something like this, maybe fixable the same way?

That's not probably it. It has to do something with handles - do you have any JASS triggers made?

 

[oveRLuckEd]

hmm, warcraft version?

 

[fr0ggE]

There is no Jass in the map, and I play in version 1.24.

The map seems to have stopped crashing. It could have been then new 1.24b patch, or maybe fixing the chainlightning trigger helped.

I'll post again if it starts crashing.
