- get_terrain and set_terrain replaced with direct indexing operations
- get_map_size mostly replaced with either the iterator or an on_board call.
Only a few cases really needed to know the size of the map for some other purpose.
- shroud and fog operations, village owner, time areas, and location filters
- get_terrain_info replaced with terrain_types table
- Map generation functions create_map and create_filter
Also backtracked the removal of wesnoth.get_recall_units, which is now available as wesnoth.units.find_on_recall - it's just more convenient than passing x=recall to wesnoth.units.find
There are no functionality changes in this commit, it's simply switching over to the new ai_helper function. Changes to the MAI functionalities will be added separately.
Most of the Fast MAI attack utils had been taken from a more general codebase and included things not needed here. This AI is supposed to be a slimmed down version doing only the absolutely necessary in as fast as possible a fashion.
(cherry-picked from commit f4f2a441e41cea635861630eb555af9f510c9b52)
This is done by ignoring shroud for path finding (while still taking
hidden units into account correctly), consistent with default Wesnoth
AI behavior.
This is not necessary for most other Micro AIs, but this AI moves many
units per execution for speed reasons. If an ambush or failed teleport
or similar happens, it is better to reconsider rather than pull through
with the rest of the moves.
Previously, the Micro AI behavior was inconsistent at best when it came
to dealing with these units and could even result in AI errors when an
AI unit was ambushed or a petrified unit was in the way of a move. Now,
both types of units are properly "ignored" and the AI moves have been
made robust against unexpected events such as ambushes. Incidentally,
the latter also makes the AI more robust against WML events doing
things the AI cannot know about (such as removing units).
This can either be an [avoid] tag inside the [micro_ai] tag itself, or
the [avoid] tag of the default AI (e.g. as defined in the side
definition). If both are given, the former has priority.
In this case, it can happen that there are no goals (e.g. if there are
also no villages or if the AI has no leader). Previously, this
situation caused an error message.
This AI is meant as a fall-back AI for scenarios where there are so
many units that attacks and moves done by the default AI are slow with
long delays before each move. It replaces the default combat and
move-to-targets candidate actions.
