Greetings Blueboy and other Bot Developers,

I've been a fan of this work for some time now and am fascinated with what has been accomplished in the solution over the past few years. I was thinking about developing a relative position controller as an academic excercise (Im currently in grad school studying controls), and figured this could be interesting with a squadron of bots. This would probably be more useful in non combat situations when the team is dungeon crawling or navigating a road and could prevent the pile up resulting from all bots tracking an equivalent follow the master command.

For such a real time algorithm, it looks like everthing is in place... master xyz position, bot xyz position, and a 1 hz time update rate with the p_time variable? Also it looks like the mbot relocate command can be used for positioning... what do you think.

Enthusiastic to make a contribution!

Sincerely,

Bramm

<relevant code snippet>

/ This is called from Unit.cpp and is called every second (I think)

void UpdateAI(const uint32 p_time

float x, y, z; pTarget->GetContactPoint(m_bot, x, y, z, 3.666666f);

m_bot->Relocate(x, y, z);

Good evening Blueboy, I'm not running any other patches or mods in the setup. From what I've seen, the crashes have occurred after spawning and grouping the bots and performing some amount of combat. I can't really pinpoint it to using an instance yet although this was the fact for one of the more recent occurences. I just updated to the a more current Revision 9573 and merged the updated blueboy thread and haven't seen anything yet. If I do, I will go add the monitor flag per your suggestion in #914 and report in w/ findings.

Thanks,

Bramm

Just a quick update to help troubleshoot some of the crashes, per post #892 I've updated w/ this patch (commented the typedefs) to Revision 9518, sd2 1627 w/ the following log:

Hello Blueboy, very impressive work sir. I've been successfully running your patch for a few days now and I must say the AI has come a long way since I last attempted to bring in this work. Nice!

I have run into a couple crashes occasionally after populating about 3 bots in a group -- the purpose of this message is to attempt to provide some helpful info on the nature of this crash for future dev.

In the mean time, I'm going to update to your latest patch as described above. Please let me know if this info is helpful at all or how I may offer assistance with this effort. Thanks.

Sincerely,

Bramm
