The Battle for Wesnoth Forums

What happens is that weather damages certain units (above or below their 50% HP and not in villages) on every turn refresh, and when this happens with the [harm_unit], something goes wrong. Sorry that I didn't mention this - you can manually debug card draws, so you can load the save, draw rain man...

If you decide to look into it, heres the topic where it was discussed, with a save file: https://forums.wesnoth.org/viewtopic.php?t=49966 But part of the problem was that it can't be reproduced reliably. Yeah ... I let it play through the AI turn >10 times and never got the error. The problem is th...

Error during Whess Screen Shot 2020-01-17 at 12.47.04 pm.png That's a sad known issue. It can happen when units are harmed by weather, but we couldn't figure out why it happens, I think the conclusion was that it's some unknown bug in Wesnoth itself, so it's on the fixlist for now. Luckily it doesn...

WackoJacko: Thanks for posting the replay. It still took me several attempts to reproduce it (because there's some randomness involved; see below), but I eventually got the error message. WhiteWolf: So this is an interesting one ... What's happening is that your random placement of rabbit holes (dir...

Glad it helped. :-) And don't worry about having more questions. As for those: 1) That should not be a problem. 2) Yes. The AI is set to be more careful with its leader, but you can change that if you want. 3) I haven't checked it carefully for typos, but it looks like that should work. Only thing I...

Are you sure you are using the tag as in my post? That error happens when you try to change (or add) an AI component without giving it new content to change to (or add); the [goal] tag in this case. Maybe you also changed the [modify_ai]action=delete instructions to action=change ? That would produc...

I assume that the behavior you observe is due to the fact that the goal you define is not the only goal the AI uses. There are also some automatically selected goals; and other considerations, such as distance to the goals, matter as well (see the first paragraphs here and here for more details). Mo...

Just for the record, my initial guess that this was due to a divide-by-zero error was wrong. A while ago I opened an issue that describes what is going on. Turns out that this is not actually an AI issue, except for one side problem with the "High XP Attack" candidate action which I fixed in commit ...

Adamant14 sent me a save (thank you!) from which I was able to reproduce the error. The problem is pretty much what I expected, the ExpAI trying to move a unit to a village that it cannot actually reach because the path is blocked by enemies. That can be fixed (well, worked-around, really) by changi...

What's the "new AI"? Based on the error message, I assume it's the Experimental AI? Just asking because that's been around for many years, so just making sure I am not missing something. :P Also, which version of Wesnoth is this? I mean, I can see from the error message that it must be 1.14, I think...

Yeah, thanks, it's always good to get these kinds of reports that point to potential (and real) problems in the MAIs. For the record, I have fixed the bug now (commits e82469ad in 1.14 and 09cffab7 in 1.15). I also added [filter] as an optional parameter to the Bottleneck MAI here . That one will no...

Hi — the information you need is given on this wiki page , section "Modifying Standard Aspects". There is even an example for the [avoid] aspect on there. It's for adding the aspect, but hopefully it will be clear enough how to remove it (which is shown for a different aspect earlier in the same sec...

Hi Spannerbag, I don't know what's going on with the Flynn arrival problem ... As for the candidate action error, the problem is that that is not how you add a candidate action . [candidate_action] tags (such as that macro) do not go directly into [ai] , but inside [ai][stage] as shown here . So you...

When I looked at your replay, I noticed something else and I finally had time to confirm it. There's a problem with the Bottleneck MAI when units are so far "in front of" the line (i.e. in enemy territory) that they cannot get behind it in one move. The MAI just doesn't move those units at all and l...

Since, with the reworks, a rebalancing is required anyway, I have no problem if @mattsc would like to make the ExpAI default (we talked about this on discord, I think he said he was merging everything besides the recruitmentAI, which would also potentially greatly affect the balance of UMC campaign...
