Random Crash Bug With TGEA 1.8.1 + FGE
by Roland Orr · in Torque Game Engine Advanced · 06/20/2009 (6:24 pm) · 5 replies
ok I am using TGEA 1.8.1 with the Flight Game Example.
I have added the GuiMeterCtrl Resource, AiFlyingVehicle, aiRepairshipFlyingvehicle, FGE Needed Scripts, GuiRadarCtrl, and GuiRecticleHud. All code and scripts have been upgraded by myself to work correctly with TGEA 1.8.1 plus i have added in some bug fixes as posted by GG staff.
The problem i am having is my game will randomly crash, sometimes it crashes when i try and load the mission, sometimes it crashes after i have died and try to respawn (respawn crash), sometimes it crashes for no reason at all, some times is crashes when a AI BOT is spawning, sometimes it will freeze up then throw a none descript windows crash error window.
All video card drivers are up to date
DirectX is up to date
Tried running in compatiblity mode for WinXP SP2 -> no change.
No script errors are reported by the console.
---
The only things i can think of is these:
1) a possible bug in the respawn script
2) a bug in the deleteObject() engine code (running a debug exe shows that the deleteObject() fuction as the last called function before crash in all cases of crashes, however i am not sure what is being deleted or trying to be deleted that is making TGEA barf)
I have tried to fix this issue myself, but after 5 days of this i need help. hopefully someone can shed some light.
any help would be great. Thanks in advance.

oh yeah i forgot to mention that i also have the WheeledFlyingVehicle working in TGEA 181 as well. It works great, and if i set my plane up right even the debris system works great.

Have you tried tracing where it crashes? Think the best approach would be to have it run in the debugger and then see where it crashes. If it doesn't crash in debug builds or when running in the debugger, then it's bad but chances are good it does. If you post a stack trace, it would be helpful to see what's going on.

It crashes in both release and debug builds. Maybe the error is easy to see but i am kinda at a lose. Visual Studio Stack Trace Debug:

Anyways, the next step is to find out why the SimObject reference is invalid. What kind of object is it? Has it been already deleted somewhere else before? Where does the reference come from?
If it is stored somewhere as a plain SimObject*, then it often helps to turn that into a SimObjectPtr which will get nulled out if the object goes away. If it is correct for the object to have died by the time the deleteObject() happens above, then simply check for NULL and delete only if the object is still there.

Apparently it tries to delete an invalid SimObject reference. Have you modified the setImageState method? In stock 1.8.0 it doesn't trigger a call to deleteObject() directly and skimming over it, I could find no place that would implicitly trigger the call.Anyways, the next step is to find out why the SimObject reference is invalid.
