20130902 01:56:08< mattsc> Hi, vultraz.  Concerning the "next_hop ..." error messages with the Messenger AI you have seen: is it possible on your map that the path toward the next waypoint for the messenger is entirely blocked by enemies?
20130902 01:56:33< vultraz> no, but there were allies, I think..
20130902 01:56:39< mattsc> Looking at the code, that's the only situation I can think of that might cause that problem
20130902 01:56:46< mattsc> Hmm.
20130902 01:57:28< mattsc> Anyways, I'll do a little fix to the AI that definitely shouldn't make things worse and that maybe will fix that problem.
20130902 01:57:41< vultraz> wouldn't that happen if ANY unit blocked the waypoint?

20130902 01:57:54< mattsc> no, there's a provision in the code for that
20130902 01:58:01< vultraz> ah
20130902 01:58:31< mattsc> units *on* the waypoints are worked around, but if the way *to* the waypoint is entirely blocked, that could cause trouble
20130902 02:00:00< vultraz> that happened too
20130902 02:03:19< mattsc> by enemy units, I mean.  Allied units might get in the way but should not produce error messages.

20130902 15:29:12< vultraz> hey mattsc 
20130902 15:29:32< mattsc> hi vultraz 
20130902 15:46:43< vultraz> mattsc: what is the experimental ai?
20130902 15:47:39< mattsc> vultraz: it's Ron ported to mainline (with some minor differences, I think)
20130902 15:48:02< vultraz> I see
20130902 15:48:19< vultraz> so basically there are 3 ai engines?
20130902 15:48:29< vultraz> rca, experimental, and lua?
20130902 15:48:32< mattsc> so mostly it's better recruiting, plus leader castle switching and village grabbing and a couple other minor things, iirc
20130902 15:49:00< mattsc> no, it's not an engine (although there are 3 anyway: c++, formula and lua)
20130902 15:49:27< mattsc> The RCA AI and ExpAI are actual AI implementation, using these engines.
20130902 15:49:37< mattsc> *implementations
20130902 15:50:42< vultraz> why do there need to be 3 engines :/
20130902 15:50:59< mattsc> Because it's fun.  :)
20130902 15:51:07< mattsc> No, seriously:
20130902 15:51:19< mattsc> I don't need to explain why the c++ engine is there, right?
20130902 15:51:57< mattsc> Then the FormulaAI engine was created, as a possibility for stupid people like me to write AIs without having to mess with c++
20130902 15:52:56< mattsc> Then, at some point Lua was added and development of the FAI engine was discontinued, so now Lua is the configurable engine, and FAI is still around but not maintained any more.
20130902 15:53:23< mattsc> That was before my time, so you'll need to ask other people for the stories and controversies surrounding that.  ;)
20130902 15:55:14< mattsc> Btw, the FAI engine does still work and is quite nice in some respects (nice than LuaAI for some things, in fact), but you can't get anybody to implement new features for you any more.
20130902 15:55:56< vultraz> what I don't get is why there can't be one C++ engine, but accessible from lua as well
20130902 15:56:19< vultraz> like the WML engine
20130902 15:56:27< mattsc> Well, that's essentially what it is.  The Lua engine is a front end to the c++ engine.
20130902 15:57:12< vultraz> I see
20130902 15:57:23< mattsc> That's pretty much what the discussion with Soliton, Crab_ and others was about when we talked about path finding with avoid.
20130902 15:57:48< mattsc> Don't rewrite it in Lua if it already exists, or almost exists, in C++.

20130902 15:58:55< vultraz> I see
20130902 15:59:00< vultraz> so the RCA AI is the default?
20130902 15:59:06< mattsc> yes
20130902 16:00:20< mattsc> vultraz: brief description of what's there is here: http://wiki.wesnoth.org/AiWML#Available_AIs
20130902 16:00:24< vultraz> so basically...we have RACI, EAI, FAI, LAI, and MAI
20130902 16:01:15< mattsc> yes, but you are mixing things here.  RCA, ExpaI and MAI are AIs.  FAI and LAI are AI engines.
20130902 16:01:45< bumbadadabum> all those AIs
20130902 16:02:12< mattsc> vultraz: I have to be off and see how wet and muddy it is out there.  I'll be back in a couple hours and can continue to add to the confusion then.
