Explain wallbreaker AI to me

This might have been discussed already but I'm having trouble finding the actual answer especially with the tweaks with each update.

So they target the closest wall with an enclosed building right? At what point is something considered enclosed? I know sometimes a long wall segment will get targetted. Does anyone know how far a wallbreaker is willing to walk to consider it enclosed? What about a funnel type enclosure? Example - if a building is inside a long segment that wraps 3 sides, will the WB break that wall? Sure if you put the WB at the opening it'll find another target, but what if on the complete opposite side?

What about an empty enclosed wall section that buffers the outer layer? I know I've had the WB target it but it might have some preferential target over this. I am asking more for a long 1x or 2x space wide buffer area and not a false 2x2 bomb/tesla spot.

I'm just having trouble tweaking my attack strategy when the WB can be somewhat of a wildcard.

Interesting questions, would like to see the answers as well :) A SC employee could clear this up, I'm sure it's hard to understand without being the programmer himself.

How fascinating question you ask us, lets go to Mod or maybe even SEE "SC" to get answers

While AI is still a mystery man for most of us, including me, this is what I have witnessed:

They attack the nearest wall in their sight (+- 10 tiles?) if that wall partially (3 sides?) enclose a building. They will target the weakest wall and walk around things like a Gold Mine.

This means if there is a polka dot wall they will attack the weakest wall, but more importantly if a Barb or a Giant has taken a swing at a wall they will target that wall, which may be not what you want with a Wizard Tower in sight.

I don't think SC is gonna give you the answer. I'll do some Goblin mission testing, and maybe find out more.

I have noticed since the last two update they will attack the section of a wall that is closest to an enclosed building. If there are gaps between the side of a building and the wall, that means they will miss the junction ...

You can't. AI of this game is a joke. After last Heroes update, AI of Wbs is the biggest joke of all time. They literally undo all fix on Wbs' AI that they implemented about a year ago.

This is too old. They have since broken the WB's AI. See below.

^Dis. Second last update, I see wb breaking a chain of lateral walls instead of penetrating deeper into the base. WB AI is so broken.

A few updates back, releasing the WB's in pairs seemed to work best. The first pair would peel back the outer layer, subsequent pairs would delve deeper in.

Since the last update, releasing them all at one time (once the threat of splash damage has passed) seems to work best for me. The first one or two will take out the outer layer, than the rest of them will, instead of running around the base like ♥♥♥♥♥♥s, will spot the next wall deeper in.

As others already mentioned, WB AI was completely broken by the hero nerf update.

WBs technically still have the AI shown in the Flammy video that was posted - BUT the hero nerf update also made the WB AI preferentially target previously damaged walls. Considering you almost always need cover troops to use WBs, guess which one almost always takes precedence? Yup, the previously damaged walls, which makes WBs unpredictable and stupid.

Supercell was made aware of this almost immediately after the hero nerf update yet they have done nothing for what should be an easy fix (reverting the WB AI to the pre hero-nerf update). Who knows what the heck they are thinking.

In any case, I only carry 4 WBs now to get my troops into the first level of a base. They are too stupid to rely on for anything else.
