Exception C0000005 when saving a game

[White Diver]

Hi,

In SP mode I get the C0000005 exception when trying to save a game starting with "Hidden threats". The probability is about 90% and does not depend on the /novista switch. Using the remaining 10% I manage to get to the "Escape path" but there is no way to win because the Recycler gets inevitably destroyed after it builds an "Undeployed". BTW, loading a game becomes slow (about 20 seconds) after a game is loaded 2-3 times.

Is there a way to win in the "Escape path"? Would be very grateful for something that can help me to go on (saved game from the next mission will do but is there a more common solution?). Sorry for my English.

That seems to be related to AOIs, a section of code that has been problematic in the past. If you're running bz2edit.exe, it supports a shortcut "-DeleteAOIsOnLoad" . This is documented in the readme13.rtf file installed with BZ2, near where it documents "-novista" . How are you reloading the map? From a savegame? Quitting to the 2D pregame menu and launching again? I'd like to see if this bug is repeatable elsewhere.

To go to the next mission, open up the console -- control+` (the key immediately left of the 1 key on US keyboards; it may be the same physical combination on your keyboard) -- and type

game.cheat bzwinner

That'll complete the current mission and progress to the next.

If this a FE mission?

[Red Spot]

Yes

Thanks for that -- as always, RTFM is the last chance... I am an experienced C++ programmer but I never tried to look what is under the hood of BZ - the fairy tale must remain the fairy tale. Anyway, if I can help the developers to make the game better -- I will do my best. Where I can learn about the technical details of BZ, is there a some document?

I am restoring the game from the savegame (Fille -> Load -> Choose a name). What does the "How are you reloading the map" mean?

If you want to looking at mission dlls (C++) might be a good idea. It would be nice to have an active programmer around here for modding. I can show you a bunch of things if you are interested. It would be nice to have an active programming modder other than myself.

AOIs are something stored into BZNs that are probably old BZ1 code. There can be too many at times, so we started to remove them from the ASCII saved BZNs (1.3 default format). Now there is a command line flag for the program to help remove them.

greg louganis, maybe?

i've been working on the FE missions, but recently took a brain break (you can only play FE missions 100 times in a row before you go numb)

check out the other subject threads in this area for FE SP DLL fixes.

At this point, the most you can do is continue to submit these error reports. As BZ2 is still closed-source, there is no way for you to help with the engine coding. You can, however, check out the modlog (found here: ModLog) to see how the different lines in the ODFs affect gameplay. You can also, as Nielk1 said, take a look at the mission DLLs to learn that way. As far as I know, there is no actual primer for getting started; your best bet will be to dive in and take a look for yourself.

Meaning, after the crash, how do you get back to the point where the failure happens? Saying that you restored from a saved game answers the question, as opposed to starting the mission from scratch and getting to that point.

[Nielk1]

NNNNNecro-post.

[VSMIT]

Blah... It was near the top of the topic list, so I didn't look at the dates.

[Ded10c]

Actually, yeah... why did it appear up there?

[Red Spot]

Yes children, and thats why we do not drink and moderate fora at the same time ...

[VSMIT]

I don't drink.
