Human-readable FFIX AI Script

Human-readable FFIX AI Scripts
The original scripts can be extracted from the Steam version or a ROM with Hades Workshop, made by Tirlititi
https://forums.qhimm.com/index.php?topic=14315.0
Slightly simplified versions, also by Tirlititi, are available on the wiki
https://finalfantasy.fandom.com/wiki/Monster_(Final_Fantasy_IX)
These versions are designed to be understood by people without coding experience, while still giving a precise description of each enemy's behaviour
The only important information left out here is endless copies of "This enemy does/doesn't use this status attack on targets with this status", since it's on basically every status attack

AttackLists
Most enemies use a system to prevent them choosing the same attack over & over
At the start of the battle their list of attacks is shuffled into a random order. On each turn the one at the front of the queue is cast and moved to the back of the queue
However, when it is moved to the back, there is a 1/2 chance it will be moved forward 1 space in the list, 1/4 chance it will be moved forward 2 spaces, 1/8 chance of 3 etc. halving each time
Finally, if it is moved all the way to the front of the queue (1/2^(n-1) chance, where n is the number of moves in the queue), there is a 1/2 chance it will be moved all the way back to the end of the list instead
This means there is 1/(2^n) chance of an enemy doing the same attack in a row, where n is the number of attacks the enemy has
This is made slightly more complicated by some enemies having multiple copies of the same attack, an enemy with 2 copies of attack A & 2 of attack B has a 3/8 (37.5%) of doing the same attack twice, instead of the 1/4 (25%) if it had 1 copy of each attack
Calculating approximate chances based on the previous turn or 2 if relatively easy (though still too complicated to do mid-battle) but the longer a battle goes on, the more information is available & the more complicated exact probabilities are to calculate

The best approach is to just keep in mind a few approximate rules
1: The more recently an attack is used, the less likely it is to be used again
2: If there are multiple copies of an attack in the pool, the effect of (1) is reduced, but not completely removed
3: If an attack has just been used, that copy will take an average of (total number of attacks in list) turns to reach the front of the queue again

-------------------BOSSES/MANDATORY ENEMIES-------------------
Alexandria bosses:
There's nothing interesting here, it's all just for handling the bosses' voice lines & death animation
The only unusual bit is that if a party member falls to yellow health against Masked Man (100->dead doesn't count), you'll be reminded to use potions at the end, wasting precious frames

Prison Cage 1
Main_Loop & Prison_Cage_Loop
handles the trance scene at the start & the death animation
Prison_Cage_ATB
Repeats the same 3 attacks: Absorb Garnet, Right Stem Steiner, Left Stem Zidane
Prison_Cage_CounterEx
After Prison Cage is attacked, if Prison Cage is above 50 HP and Garnet is below 25 HP: the character who just attacked will be reminded by the other to heal Garnet, with increasingly urgent dialogue. If Garnet is healed above 70 HP, the dialogue will reset to the start, but her maximum HP is 68, so the level of urgency gets stuck at the maximum.

Prison Cage 2
Identical to 1, without the healing reminders

Baku (missing from the wiki, extracted from the game)
attacklist = [ Rrrragh! ; Gwahaha! ; YEOWWW! ; ARGHHH! ]
Gwahaha! is a slightly stronger (10 attack vs 9) attack. YEOWWW! is a miss
Baku_Loop & Baku_CounterEx
Handle death animation & taunting. Baku will taunt once after the first attack, then again after the second, but not after that

Plant Brain (now things get actually complicated)
Main_Init
A bunch of animation set-up. The only thing the matters to gameplay is that it checks if Zidane is dead or at yellow hp at the start of the fight
Main_Loop
Handles the animation when Blank shows up & sets Plant Brain's HP to plantbrainmaxhp. Confusingly, by this point plantbrainmaxhp will have already been set to HALF of Plant Brain's original hp (in Plant_Brain_Loop)
Plant_Brain_Loop
First, if Blank isn't there, it tries a number of tests to see if he should be called. If Plant Brain's attacked 6 times, Blank is called. If Plant Brain is at 0 HP, Blank is called. If Zidane is dead & has been alive at some point this fight, Blank is called. If Zidane is at yellow HP & has been above yellow HP at some point this fight, Blank is called.
Second, a number of checks are done of Zidane's HP to keep track of whether Zidane has been alive/above yellow HP, as part of the Blank-calling checks above
Third, if Plant Brain has a multi-Thunder queued up, but only one party member is left alive, the attack is cancelled & replaced with another
Plant_Brain_ATB
The first attack is always Pollen, Pollen can only be used once
attacklist = [ Right Tentacle ; Thunder ; Thunder ]
Right Tentacle targets randomly, and turns into Left Tentacle (slightly more powerful) if it targets characters on the left (Zidane & Blank by default)
The first Thunder on the list targets the whole team, if only 1 party member is alive, this attack cannot be used (it is still in the list for the purposes of same attack prevention though. Because of this, repeated attacks will be slightly more common 25%->37.5%)
The second Thunder on the list can target anyone except Vivi
If Blank hasn't been called, and Zidane isn't at yellow HP, there is a 2/3 chance that single target attacks will be retargeted at Zidane. This gives a default 29/54 (53.7%) chance of targeting Zidane (87% if you count multi-Thunder)

Plant Spider
attacklist = [ Tentacle ; Thunder ]

Black Waltz 1
Black_Waltz_1_Loop
Summons Sealion at the start. If Sealion is dead/stop/petrify etc., stops BW1 from targeting Sealion. If Sealion is below max HP, force BW1 to heal Sealion
Black_Waltz_1_ATB
Doesn't use attacklist. If he's out of MP (starts with 9999) he'll Hit a random party member. Otherwise, if Sealion is below max HP, BW1 heals Sealion (the 2 Blizzards are just 2 different voice lines). Otherwise, there's a 50/50 chance each of Fire & Blizzard on a random party member

Sealion
Sealion_Loop
Plays the animation at the start & sets which HP values will change its jewel's colour
Sealion_ATB
attacklist = [ Wing ; Wing ; Blizzard ]
Nothing fancy here
Sealion_CounterEx & Sealion_Counter
Changes Sealion's gem colour. The first time the gem is yellow after your party attacks, activates Blizzara. The first time it's red, activates Tsunami.

Black Waltz 2
Black_Waltz_2_Loop
Start of battle, runs the opening animation & sets BW2's ATB to full. If BW2's at 0 HP, run the death animation. If everyone except Dagger is dead & Dagger is asleep, trigger Game Over.
If BW2's current/last target is dead, don't continue with the attack (this doesn't empty their ATB, but does prevent counters until the ATB fills up again). If BW2 is mid-way through the Hypnotize process, and a character is revived, reset the Hypnotize process
Black_Waltz_2_ATB
attacklist = [ Fire ; Blizzard ; Thunder ; Teleport ; Teleport ]
If Dagger is awake & everyone else is dead, start the Hypnotize process: First time is a taunt followed by Hypnotize, second time & after (if the process is reset by reviving a character) is a skipped turn followed by Hypnotize
If exactly 2 party members are alive & one is at low health, there is a 50% chance BW2 will skip a turn. This cannot happen twice in a row
The first attack will always be teleport, after that they use the attacklist as normal. Always on a random target except Dagger.
There is some logic to cast Osmose if BW2 is at low MP, but this will take 502 spells
Black_Waltz_2_Counter
If BW2 has just been hit and is under half health, counter with Fira on everyone except Dagger. This can only happen once
BW2 counters Fire/Fira/Blizzard/Blizzara/Thunder/Thundara with multitarget versions of the same spell

Black Waltz 3
Black_Waltz_3_Loop
Sets up all the animations & ATBs at the start & the end of the battle. If BW3 is in the air, their Evade is 99 & their Magic Defence is reduced by 3. This is reset when they land
Black_Waltz_3_ATB
attacklist = [ Hit ; Fira ; Blizzard ; Thundara ]
BW3's first turn is part of the opening animation. BW3's second turn cannot target Vivi, but all later turns can
While on the ground, BW3 uses a normal attacklist
While in the air, BW3 casts multi-Thundara twice, then lands. They will land immediately if they're out of MP (after 28 casts)
Black_Waltz_3_CounterEx
When BW3 starts flying, their currently queued attack is prevented, and they rechoose once they're in the air
Black_Waltz_3_Counter
Counters normal Attacks by flying if they're on the ground, or taunting if they're in the air (taunts only once)

Type A
attacklist = [ Strike ; Fire ; Blizzard ; Thunder ]

Gizamaluke
Gizamaluke_Loop sets up the starting animation & finishing animation
Gizamaluke_ATB
Doesn't use attacklist. 50% chance of Water, 50% chance of Crash. Water is replaced with the multi-target version at 1/3 health
Gizamaluke_Counter
50% chance to counter physical attacks with Crash, 50% chance to counter magic attacks with Silent Voice

Beatrix 1
Beatrix_Loop
Handles the animation at the end of the fight
Beatrix_ATB
attacklist = [ Attack ; Attack ; Attack ; Attack ; Thunder Slash ; Thunder Slash ; Shock ; Shock ]
If Beatrix has already attacked 10 times, wait until Jump is finished, then Stock Break. Otherwise, uses a normal attacklist

BW3-2
Black_Waltz_3_Loop
If Black Waltz 3's target dies, cancel & rechoose the attack (to avoid hitting Garnet)
Black_Waltz_3_ATB
attacklist = [ Hit ; Fire ; Blizzard ; Thunder ; Freeze ; Hit ; Hit ; Hit ]
If everyone except garnet is dead, alternate between hitting themself & talking. Otherwise, normal attacklist

Ralvurahva
Ralvurahva_Loop
When Ralvurahva's at 0 HP, cancel its current attack & queue up an Escape (so it'll be after all the currently queued attacks)
Ralvurahva_ATB
attacklist = [ Devil’s Kiss ; Devil’s Kiss ; Devil’s Kiss ; Devil’s Kiss ; String ; String ; Blizzara ]
By default, uses normal attacklist
If 2 characters are poisoned and no characters are asleep, 50% chance of casting Night
If Ralvurahva doesn't have enough MP for Night (after 300 casts), it has 2/3 chance of using Devil's Kiss (even if it wasn't planning to use Night anyway)

Antlion
Antlion_Loop
Handles the battle start & end animations
Antlion_ATB
attacklist = [ Sandstorm ; Fira ; Fira ; Trouble Mucus ; Trouble Mucus ]
The first time Antlion's ATB fills after going below half health, use Sandstorm (does not replace currently queued attack)
Antlion_Counter
2/3 chance of countering Attack with Counter Horn

Soldier
1/3 chance of using Blizzara, 2/3 chance of using Slash
Has logic to prevent casting Blizzara on targets with Reflect
Counters the first attack that brings them below 1/10 HP with Escape

Type B
attacklist = [ Thundara ; Fira ; Osmose ]
Escapes if below 2 MP after turn 10 (takes 30 casts, more if Osmose)

Beatrix 2
Beatrix_Loop
Handles the battle end animation
Beatrix_ATB
attacklist = [ Attack ; Attack ; Attack ; Attack ; Thunder Slash ; Thunder Slash ; Shock ; Shock ]
Automatically ends the fight on turn 11. The first attack after she's below half health is Cure (does not replace currently queued attack)

Tantarian
Tantarian_Loop
Tantarian starts closed, so this sets up high (Magic) Defence & the page system
Tantarian_ATB
If closed: 1/4 Edge, 1/4 Doom, 1/2 Paper Storm
If open: 5 Poisons, Close Book
Tantarian_Counter & Tantarian_CounterEx
Updates page counter, updates (Magic) Defence & Fire weakness when it opens/closes
Page count only resets if Tantarian is targetted while open, Steal/Magic works, What's That!? does not
Attack, Jump, Charge! & Throw all make Tantarian Close

Zorn
Zorn_Loop
Handles the start & end animation. Constantly refills ATB if Zorn isn't jumping.
Zorn_ATB
If Zorn isn't jumping, start jumping. If Zorn is jumping & powered up, cast Meteorite. If Zorn & Thorn are jumping & neither are powered up, Power Thorn
Zorn_Counter
Counters attacks that damage them (except Eidolon & Six Dragons)
If neither is jumping, start jumping. If Zorn is jumping, stop jumping. If Zorn is powered, unpower Zorn. If Thorn is jumping, and Zorn isn't powered, Power Thorn
Zorn_CounterEx
Power Zorn un-queues Zorn's currently queued attack & sets their ATB to 0

Thorn
Same as Zorn

Beatrix 3
Beatrix 2 again with Cure->Cura, Stock Break->Climhazzard

Bandersnatch
attacklist = [ Rush ; Rush ; Thundara ; Tongue ]

Type C
attacklist = [ Strike ; Fira ; Blizzara ; Thundara ]

Ralvuimago
Ralvuimago_ATB
If not curled up, normal attacklist = [ Stab ; Stab ; Thundara ; Thundara ; Ultra Sound Wave ; Ultra Sound Wave ]
If curled up, skip a turn, then use Return
Ralvuimago_Counter
If not curled up, counter Attack with Stiffen. If curled up, counter Attack with Power of the Land
Ralvuimago_CounterEx
When stiffen is used, cancel queued attack and increase (Magic) Defence to 255
When Power of the Land or Return is used, reset (Magic) Defence

Lani
Lani_Loop
Sets Lani's ATB to full at the start of the fight, runs the animation at the end of the battle
Lani_ATB
attacklist = [ Attack ; Scan ; Blizzara ; Fira ; Thundara ; Water ; Aera ; Attack ]
First attack is always a normal attack on Dagger (if she's alive)
If Lani is focusing a character (see Lani_Counter), she always targets them. If she isn't focusing anyone, she targets Dagger. If Dagger is dead, Lani will choose her targets randomly. Water always targets the whole party
If the second copy of Attack is used on the first or second turn Lani is focusing someone, she will taunt and use a stronger attack (36 instead of 30). This can be done twice, once targetting Dagger, and once targetting anyone else
Lani_Counter
If Lani is hit below half health for the first time, she taunts. This takes priority over all other counters
Once Lani's has queued up 4 attacks (not counting the start) she will be ready to counter. She will only counter normal attacks
If Dagger attacks while Lani's ready to counter, Lani will taunt & move her current attack to the bottom of the queue. She will focus on Dagger until she has queued up 3 attacks (including the current one), after which she will be ready to counter again.
If anyone else does so, Lani will do the same, except her taunt will be replaced with a strong (36 instead of 30) Attack & she only needs to queue up 2 attacks (again, including the current one).
Lani can counter Dagger while focusing another character, but not the other way around. The process is exactly the same as if Dagger attacked while Lani was not focusing anyone
All counters move her currently queued attack to the bottom of the queue
Because her counter is based on her ATB, it's possible for the first attack after her turn to hit just before she's ready to counter. However, because of her high speed, ATB Wait must be used to fit in 2 attacks before she's ready

Hilgigars
attacklist = [ Knock Down ; Knock Down ; Hiphop ; Earthquake ]
First attack after he's below 50% health is always Curaga (does not un-queue current attack)
