Artificial intelligence (AI) means the intelligence of machines, and is commonly used to refer to computer-controlled units in RPGs. Enemies are AI-controlled, but in certain cases, player characters can also be computer-controlled.
With the status effects Berserk and Confuse allies are taken out of the player's control and start performing actions on their own. Even if Confuse is always considered a negative status, Berserk can be used to the player's advantage at times, and is considered a positive status in some games.
1st Turn: Fang (33%) or Attack (33%) or Attack (33%)
If attacked by anything: Attack (33%) or Nothing (66%)
In the Dragon's Neck Coliseum player characters are controlled by the computer and will randomly use any commands they have available, even ones that can kill the character, like Self-Destruct. Thus the battle outcomes are often random and risky.
Umaro is an optional playable character who cannot actually be controlled in battle and is in a constant state of Berserk. Umaro only uses physical attacks, unless equipped with his special relics that allow him to randomly use a special ability.
Gau can emulate a monster. When he does he becomes a computer-controlled character in battle, and has the chance of using two abilities. One of them is always an Attack, the second can either be a special attack, a magic spell, a lore, a dance ability, or an enemy spell.
When Mog selects a Dance, he will randomly perform one of four abilities from the selected dance. The player will lose control of Mog while he's dancing.
Sephiroth, while as a party member, is entirely computer-controlled. He can attack enemies with physical attacks and powerful magic that targets all opponents. If Cloud is dead, Sephiroth can use Life2 on him.
Vincent Valentine is computer controlled when using his Limit Breaks. When using his Limit Break form Vincent has a random chance of either using a physical attack or a special attack, but the special attack is always rarer, in each of his turns.
In the Chocobo Races the player can let the chocobo be controlled by the computer, in which case the chocobo is controlled the same as the other opponent chocobos on the track. The computer does not usually take the most effective turns on the race tracks, however, and might waste Stamina.
Rinoa Heartilly's Limit Break, Angel Wing, turns her into a sort of Magic Berserk state, in which she is computer-controlled and casts random magic from her stock, without actually expending the spells. Because Rinoa only casts spells she already has, it is easy to manipulate Angel Wing by letting her only have powerful spells, such as Meteor.
Magus Sisters and Yojimbo are optional aeons whose commands the player cannot actually directly control. While commanding the Magus Sisters, the player offers suggestions to each one individually, and the AI will choose a relevant ability and target. Sometimes they may fail to take an action.
The player uses gil to manipulate Yojimbo's actions: the higher the amount paid the better attack will Yojimbo perform. The Overdrive gauge also plays part of which action will Yojimbo choose.
Player can set the player characters' gambits to have them perform actions automatically in battle. The player is still able to interrupt these actions and give the characters commands manually, but if the character has no player commands to execute, they will act according to their gambits.
Guest characters are computer-controlled allies. In the original version they were entirely computer-controlled, but in the International Zodiac Job System version the player is able to set the guests' gambits. Also in the original version, Espers are entirely computer-controlled, but in the Zodiac Job System version player gains full control of them.
The battle system in Final Fantasy XIII has the player control the actions of the party leader, and the computer controls the two others. The player can also choose the Auto-Battle option, which has the AI choose the commands for them depending on various battle situations. The actions the computer performs depends on the characters' Paradigm Roles.
The developers wanted players to feel they are actually with friends, and thus built up AI and animation system on that. During the project, the team considered developing an open seamless world and developing realistic AI for Noctis's friends the main challenges. The allies were designed to pay attention to Noctis and walk together with him, but randomize the speed and the distance from the player character. If they get left behind they come running. Because the system is constantly calculating the friends' AI, its CPU cost is high.
In Final Fantasy Tactics the player controls most party members, but not Guests, who have similar intelligence to enemies, but fight on the side of the player. There also is an Auto-Battle mode, where you can select actions for the characters (such as "Fight for Life") but they will execute them themselves, as if they were Guests.
Benjamin's ally, if present, will be guided automatically by the computer. The AI control character will exploiting enemies weaknesses or cast their most powerful spells on the enemy party. There is a bug that involves Phoebe being controlled by the AI. When controlled by the computer, Phoebe will sometimes randomly cast Aero, a spell she does not have in her possession.
Temporary party members have poor AI. They'll attack walls and trees, and even thin air for no apparent reason making them hardly useful.
The Auto function allows the player to set a character(s) on an automated function, where one or more will become automated. When a character(s) are set to Auto control, they will usually act in a manner befitting the situation.
Artificial intelligence (AI) is the intelligence exhibited by machines or software. It is an academic field of study which studies the goal of creating intelligence. Major AI researchers and textbooks define this field as "the study and design of intelligent agents", where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term in 1955, defines it as "the science and engineering of making intelligent machines".
