AI in computer games
Game developement
What is AI?
The abbreviation AI stands for artificial intelligence. Artificial intelligence is designed to imitate certain human decision-making structures. In 1950, the British mathematician and computer scientist Alan Turing formulated the “imitation game”. The process was later renamed the “Turing test”. The test was designed to determine whether a computer could convincingly imitate the behavior of a human being. To do this, a person is placed in front of a computer with which they communicate with two unknown entities. One of the two is another person, the other is a machine. If the human is unable to tell which of the two entities is the machine after being questioned in detail, the machine has passed the test. The machine therefore has a distinct intelligence - the term artificial intelligence was later introduced.
AI in games
In games, the behavior of opponents or NPCs (non-player characters) is often referred to as AI. How enemies in a video game behave when an opponent approaches is a form of intelligence. But what an NPC says also at least simulates intelligence. An NPC usually has a so-called decision tree in its code: “If the player does/says X, respond with Y”. If you look closely at the cult game Pac-Man, you will notice the following: Only one of the ghosts actually chases the player. It can be said that video games simulate intelligence, even if it is often not AI per se. The “game AI” therefore only serves to improve the player's experience. If you are looking for a true AI in a game, the chess computer can be used as an example.
There are programs that have been able to beat grandmasters several times and thus even surpass the intelligence of a human being. Such a chess program tries out every possible move and evaluates the consequences. The best possible move is then executed based on the result. The human brain cannot keep up with this computing power. The Turing test could therefore be reformulated in such a way that the test subject has to find out which player the computer is. With a modern chess computer, very few people would recognize that it is a machine: The test would therefore be passed with a high degree of certainty.
Conclusion
Artificial intelligence in computer games is usually not real AI. Instead, it's more of a factor to enhance the experience. If the player is given a feeling of immersion, the “AI” has fulfilled its task. A chess computer can be said to be real AI.
