New AI Teams Selector by FS-21 · Pull Request #810 · Phobos-developers/Phobos

More details in the documentation:

New AI system for selecting valid triggers in multiplayer randomly. Unlike the original method this one checks prerequisites and take care of other details.
It can split the valid triggers into 5 categories: ground vehicles, infantry, air, naval & mixed categories. If set, AI picks a random trigger in a random category.
Categories can have different chance probabilities. It can be set globally or customized per house. By default each category has a 20% chance to be selected.
NewTeamsSelector.MergeUnclassifiedCategoryWith can be used for merging the mixed category (units are from different categories) into one of the main categories.
In case of picking a category without valid triggers exist a fallback mode that allow picking a trigger from all valid triggers like if categories were disabled.
If Autocreate=yes AI will care about all units prerequisites so if the house's tech tree is incomplete for the trigger it gets discarded. It understands Ares tags like Prerequisite.RequiredTheaters, Prerequisite.Negative, Prerequisite.Lists & Generic prerequisites section.
NewTeamsSelector.VIPWeight controls the VIP trigger threshold. If a trigger meets this threshold, AI discards non-VIP candidates and picks exclusively from VIP triggers with equal chance (categories are bypassed in VIP mode).
- Defaults to 5000.0 (vanilla behavior).
- Setting NewTeamsSelector.VIPWeight=-1 enables dynamic VIP mode where each trigger becomes VIP when its Weight_Current >= Weight_Maximum.
- Setting NewTeamsSelector.VIPWeight=0 disables VIP mode completely.
Units can override the category using ConsideredVehicle and ConsideredNaval boolean tags.
AI is able to use unlocked units in captured Secret Labs.

In rulesmd.ini:

[AI]
NewTeamsSelector=false                               ; boolean
NewTeamsSelector.SplitTriggersByCategory=true        ; boolean

NewTeamsSelector.MergeUnclassifiedCategoryWith=-1    ; Integer - Ground: 1, Air: 2, Naval: 3, Infantry: 4
NewTeamsSelector.VIPWeight=5000.0                    ; floating point value, -1 for dynamic max weight, 0 to disable

[SOMEHOUSE]                                       ; HouseType
NewTeamsSelector.MergeUnclassifiedCategoryWith=   ; Integer - Ground: 1, Air: 2, Naval: 3, Infantry: 4

NewTeamsSelector.VIPWeight=                       ; floating point value, -1 for dynamic max weight, 0 to disable

[SOMETECHNO]        ; TechnoType
ConsideredNaval=    ; boolean
ConsideredVehicle=  ; boolean

Modified slightly AI Trigger conditions 0 (enemy owns ...), 1 (house owns ...) and 7 (civilian owns ...) and added 10 new conditions (from 8 to 17) that check lists of objects instead of only 1 unit. The first 3 were modified because the objects counters weren't updated in real-time. The possible modified and new cases are:

Condition	List of objects	Description
0 (changed)	No	Count objects of the main enemy. If AI house doesn't have a main enemy It will search in all enemies. In vanilla YR if house doesn't have a main enemy this condition fail
1 (changed)	No	Count own objects
7 (changed)	No	Count civilian objects
8	No	Count enemy objects. It will search in all enemies
9	Yes	Count enemy objects. If AI house doesn't have a main enemy It will search in all enemies.
10	Yes	Count own objects
11	Yes	Count civilian objects
12	Yes	Count enemy objects. It will search in all enemies
13	Yes	Count objects from allies
14	Yes	Count enemy objects. If AI house doesn't have a main enemy It will search in all enemies. It uses `AND` comparator so each object must obey the same comparations
15	Yes	Count own objects. It uses `AND` comparator so each object must obey the same comparations
16	Yes	Count civilian objects. It uses `AND` comparator so each object must obey the same comparations
17	Yes	Count enemy objects. It will search in all enemies. It uses `AND` comparator so each object must obey the same comparations
18	No	Count structures with `BridgeRepairHut=yes` linked with destroyed bridges
19	No	Count structures with `BridgeRepairHut=yes` linked with undamaged bridges

Some trigger conditions need to specify a 0-based list from [AITargetTypes]. The index of the list is written in hexadecimal and in little endian format. The value must be written at the end of the trigger:
00000000000000000000000000000000000000000000000000000000AABBCCDD
For example: list 0 is written 00 (put it in AA), list 1 is written 01 (put it in AA), list 10 is written 0A (put it in AA), 255 is 0xFF (put it in AA) and 256 is 0x0001 (put it in AABB), etc.
The AITargetTypes index# values are obtained in the new AITargetTypes section that must be declared in rulesmd.ini:

In rulesmd.ini:

[AITargetTypes]  ; List of TechnoType lists
0=SOMETECHNOTYPE,SOMEOTHERTECHNOTYPE,SAMPLETECHNOTYPE
1=ANOTHERTECHNOTYPE,YETANOTHERTECHNOTYPE
; ...

If set this option.

This comment is automatic and is meant to allow guests to get latest nightly builds without registering. It is updated on every successful build.

Fixed all the bugs related to the Teams categorization, now all the AI teams go to the right category depending the members of the Taskforce. Added 2 new boolean tags for overwriting the categorization of some units: - ConsideredNaval - ConsideredVehicle

Now AI will be able to unlock secret lab units and use them in Teams. Other bugfixes and improvements.

- Prerequisite tags were cleaned after a change of map/restart. - More laxed when adding the AI triggers in their respective houses arrays. The main Team's selection loop will decide if the trigger is currently valid. - Some code tweaks & additional log lines in the AI selection loop. - Now AI teams are directly discarded from the selection loop if doesn't exist the required factories if Autocreate=yes
