Here is the terminal output:

This is on version 3.9.0 (Built Nov 7, 2013 Rev: 4846) running on Ubuntu 12.4 on a Lenovo W510, i7 processor, 16GB RAM. Downloaded from megaglest.org.
I saved the game less than a minute before this error occurs. I can repeat this error every time by loading the saved game and just waiting, or doing just about anything. It fails every time.
I can send the saved game, if needed.

I'm not sure if this is a problem with MegaGlest so much as the Island Survival scenario.
It's unfortunate that the error messages don't specify the line of the Lua script that made this invalid call. I imagine this is a case of a giveAttackCommand call that is using the ID of a dead unit as either the target or source.
If one of the devs can verify that this is indeed due to the scenario, I'll merge this into the island survival thread.
Perhaps these kinds of errors should state the location of the error in the script, however? The error message posted doesn't seem very useful to scenario developers.
@SlowMO, could you upload your save file? I imagine that Tiger will find that useful in tracking down where in his scenario this occurs.
-
I am not seeing where I can upload the file.
-
The forum doesn't provide a way to upload files, please use any file hosting site which allows for free and direct downloads.
-
I am quite sure too that this is a bug in the scenario code. ( https://forum.megaglest.org/index.php?topic=9276.0)
-
This is an error in the scenario.
It is caused by the survival island scenario.
The Cause is that one of your main buildings (such as house or defence tower) has died. Unit spawn and attack those units which causes the game to crash.
This may be fixed in the next release of the scenario. But for now just don’t let your "main" buildings die.
-
While the trigger is a bug in the scenario, ideally buggy scenarios should not have the potential to crash the game entirely. Instead, what should happen is that a message window pops up saying that the scenario encountered a problem and had to be ended, returning the user to the main menu or, if it cannot be guaranteed that the game will continue to be stable after this point, should state that the game will have to quit as a result and do so as soon as the user confirms the message.
-
Yes I agree, that should not be a reason for the game to end.
-
It is the scenario that died, and the game does return to the main menu, so the exception handling appears to be working fine. The error message just needs to be "cleaner" that it is a problem with the scenario. It's nice to know not to let my main buildings die. When I moved to the 1.2 version of the scenario, it is less likely to happen now that the bees don't spawn till later and are not quite so aggressive.
BTW, this is a great scenario, thanks Tiger.
-
I committed an update in git HEAD which will display the error in a messagebox and not exit the game (however the game may not be stable due to the script no longer running as expected.
-
Thanks for the improvement, Softcoder. I think if stability is likely to be impacted it may be better to force quit after the message has been read/confirmed. We would not want players to start / join another game after the fact and get disconnected in the middle of a game...
This said, if the message displayed there is clear enough about the stability issues then I don't think strictly forcing quit is needed.
-
The first part of such errors says: The game may no longer be stable!
Thanks
-
Great, thanks (and sorry for not looking at what you committed)!
