0.74B1 groupai crash help

Ah, those headers aren't covered by the ABIC layer, so that might explain the crashes when using it... I wouldn't know what's causing them with the standard interface though, does your AI perhaps export the function "IsCInterface"?

Firstly

DevC++ AIs crash spring.

Codeblocks AIs are better.

Secondly, a few things about the C ABI

This only works for Skirmish AIs, and wont work for GroupAI.

Also there are a few items missing from the ABI, and a huge list missing from the c++ wrappers.

namely:

By far the best choice is to just compile in Mingw32 or develop in C#.

is there a way to make devc++ or vc++ use mingw? devc++ has it in its installation

AF · Post by AF » 15 Dec 2006, 01:48

The vesion of mingw32 in devc++ is really old.

Use codeblocks instead.

And you can get VS to use mingw32 if you really want to but its a nasty process.

Compile spring and your AI in VS to test and compile with mingw32 for release.

Bobcatben · Post by **Bobcatben** » 15 Dec 2006, 01:51

whats weird is, one of my groupais compiles and runs fine with g++ in devc++, but the other doesnt, and the reason i dont use mingw is because ive never directly used a compiler in windows, only through a IDE.

AF · Post by AF » 15 Dec 2006, 01:55

NTai compiled under Devc++ crashes at startup trying to parse the unit learning data.

The same code runs perfectly when compiled in VS 2003 or the mingw32 that comes with codeblocks.

Post by **ILMTitan** » 15 Dec 2006, 06:37

Has anyone here tried using Eclipse as their C++ IDE. I love it for Java, but don't really know how well the C++ plugin works.

No need, just overwrite devcpp's gcc and other stuff with recent mingw stuff (http://www.mingw.org).

Bobcatben · Post by **Bobcatben** » 16 Dec 2006, 04:56

hmm, i upgraded the mingw in devc++, still, one of my ais works fine, and one crashes, while back when vc++ compiles worked, they both worked, without any code changes since then.

AF · Post by AF » 16 Dec 2006, 05:00

I'd still use codeblocks as its by far a better IDE, devc++ just hasnt been updated for so long its not worth it.

Also try debugging it, it may be your code not your compiler.....

I'd also love to hear opinions on this.

Bobcatben · Post by **Bobcatben** » 18 Dec 2006, 01:10

hmm, well iupgraded the mingw in devc++, my 2nd of 3 AIs still crash on loading, the first one works perfectly, the 3rd one works, but spring does the runtime crash when shift is pressed after my AI is loaded, but the first AI of the 3 doesnt crash it when its pressed... so weird

Code completion is so slow it's practically unusable, and that's the only imaginable reason I'd want to work on C++ in Eclipse.

Bobcatben · Post by **Bobcatben** » 18 Dec 2006, 02:06

ok so, apparently, mingw's version of deque isnt smart enough not to execute pop_front, if its empty..... and was crashing it..., and low and behold now that the second of 3 ais loads and works, it doesnt crash from shift, but the 3rd does... and its the simplest of any of my ais... how odd

AF · Post by AF » 18 Dec 2006, 02:20

oddly enough none of them do, I had this bug in my early days using Visual Studio...

Bobcatben · Post by **Bobcatben** » 18 Dec 2006, 02:23

well, my visual studio 2003's version is smart enough, but anyway, that ai works now, now im just stumped as to why the shift key crashes my nano tower manager AI

AF · Post by AF » 18 Dec 2006, 02:26

Check your DLLEXPORT bool IsUnitSuited() function

Bobcatben · Post by **Bobcatben** » 18 Dec 2006, 02:32

Code: Select all

DLL_EXPORT bool IsUnitSuited(unsigned aiNumber, const UnitDef* unitDef)
{
		return true;
}

the same as the rest of my groupais

Edit: fixed it, i got no more problems now, apparently mingw's version of vectors dont initialize themselves when created, so a commands.clear() in initAI fixed it.

Bobcatben · Post by **Bobcatben** » 18 Dec 2006, 04:42

its all fixed, but i have a few of questions.

1: why is the build distance from unitdef slightly larger then the real allowable builddistance, i noticed in my nanotower manager, when it tries to reclaim something near the edge of its builddistance, it thinks it has to walk there, which it cant.

2: is there a way to tell if a wreckage was built(like dragons teeth) or from a unit dieing.

3: is there a way to tell what the unit id is of what a unit is building(not the unitdef id, but ingame id) or what a unit is currently doing.

Figuring this out would require a parent global AI acting in tandem as a silent watcher, else the groupAI just doesnt have the necessary information available, nor the scope to derive it. It would need tor ecieve the full range of events from the entire game as and when ti happens regardless of wether a unit is under its control.

although n#1 and n#2 can still be subtly derived using inference, aka unit A has a command to build X at position Y and an unfinished unit B is at X of type Y.....
