Capcom held a conference at CEDEC 2024 (Computer Entertainment Developers Conference 2024) on August 22 (as reported by Famitsu<\/a>). The presentation was held by Street Fighter 6<\/strong> planner Naohiro Yasuhara, who gave fascinating insights into how the game\u2019s CPU (AI) was programmed and structured to behave in a human-like and organic way regardless of difficulty level. <\/p>\n\n\n\n

*The “CPU” used here refers to the thinking routine of the CPU-controlled character, i.e., the logic that determines its behavior. <\/p>\n\n\n\n

Interestingly, to explain the inner structure of Street Fighter 6\u2019s CPU, Yasuhara uses the analogy of a card game, treating each individual action the CPU performs as a card. The CPU, much like a human player, has a limited set of actions they can perform in each given situation. For example, if the opponent jumps, you may choose to guard or use an anti-air attack. These sets of actions (cards) that correspond to specific situations are grouped into what Yasuhara calls \u201ctactical card decks,\u201d and these smaller decks are what make up the CPU\u2019s greater \u201cstrategy deck.\u201d <\/p>\n\n\n\n

The higher the CPU\u2019s level, the richer its library of \u201ctactical card decks\u201d (i.e. actions they can perform) becomes, meaning it can weave in more diverse strategies. The CPU decides what deck to draw from based on the current situation it’s in, as well as the given difficulty level. But for selecting \u201cthe final card to play,\u201d another factor comes into play \u2013 the CPU\u2019s \u201cability to execute\u201d an action. This is another parameter that increases with the CPU\u2019s level. <\/p>\n\n\n\n

In Street Fighter 6, much like a human player, the CPU needs to properly input commands in order to perform actions, which means it is also susceptible to making input mistakes. Yasuhara shows an example of a CPU-controlled Zangief seemingly randomly wasting an opening in the opponent\u2019s defense by jumping back instead of attacking. A look at the CPU\u2019s command history reveals that it failed to connect the inputs for a Spinning Piledriver correctly \u2013 the kind of mistake you\u2019d expect from a human. <\/p>\n\n\n\n

According to Yasuhara, Street Fighter 6\u2019s CPU has an internal gauge that represents how much \u201cpressure\u201d it\u2019s feeling in the current moment, and based on this value, the accuracy of its inputs fluctuates. The lower the level of the CPU, the heavier it’s affected by pressure, lowering its ability to execute tasks. <\/p>\n\n\n\n

At low levels, the CPU has few available tactics and poor execution ability. At level 6, which is an intermediate level, its tactics are still relatively limited, but its execution ability is high. Then, at level 7, the tactics become more advanced, but execution ability is unstable, making the CPU susceptible to mistakes in judgment and commands.  <\/p>\n\n\n\n

Street Fighter 6\u2019s CPU has been earning praise for its nuanced and realistic behavior<\/a> since the game\u2019s first demo, and this sneak peek into how its logic works, explained cleverly through Yasuhara\u2019s card game analogy, allows even the non-tech-savvy appreciate the design. <\/p>\n","protected":false},"excerpt":{"rendered":"
