Another development in recent game AI has been the development of "survival instinct". In-game computers can recognize different objects in an environment and determine whether it is beneficial or detrimental to its survival.

Like a user, the AI can look for cover in a firefight before taking actions that would leave it otherwise vulnerable, such as reloading a weapon or throwing a grenade. There can be set markers that tell it when to react in a certain way. For example, if the AI is given a command to check its health throughout a game then further commands can be set so that it reacts a specific way at a certain percentage of health.

If the health is below a certain threshold then the AI can be set to run away from the player and avoid it until another function is triggered. Another example could be if the AI notices it is out of bullets, it will find a cover object and hide behind it until it has reloaded.

Actions like these make the AI seem more human. However, there is still a need for improvement in this area. Another side-effect of combat AI occurs when two AI-controlled characters encounter each other; first popularized in the id Software game Doom , so-called 'monster infighting' can break out in certain situations.

Specifically, AI agents that are programmed to respond to hostile attacks will sometimes attack each other if their cohort's attacks land too close to them. This can include dynamic game difficulty balancing , which consists in adjusting the difficulty in a video game in real-time based on the player's ability. Game AI may also help deduce player intent such as gesture recognition. Procedural-content generation : Creating elements of the game environment like environmental conditions, levels, and even music in an automated way.

AI methods can generate new content or interactive stories. Data mining on user behavior: This allows game designers to explore how people use the game, what parts they play most, and what causes them to stop playing, allowing developers to tune gameplay or improve monetization. Rather than procedural generation, some researchers have used generative adversarial networks GANs to create new content.

In researchers at Cornwall University trained a GAN on a thousand human-created levels for DOOM ; following training, the neural net prototype was able to design new playable levels on its own.

Her one word answer was "Cheat. Wilson of Computer Gaming World , [29] Gamers always ask if the AI cheats presumably so they can complain if they lose — Terry Lee Coleman of Computer Gaming World, [30] In the context of artificial intelligence in video games, cheating refers to the programmer giving agents actions and access to information that would be unavailable to the player in the same situation.

Common variations include giving AIs higher speeds in racing games to catch up to the player or spawning them in advantageous positions in first person shooters. The use of cheating in AI shows the limitations of the "intelligence" achievable artificially; generally speaking, in games where strategic creativity is important, humans could easily beat the AI after a minimum of trial and error if it were not for this advantage.

Ho et al. Perez et al. Cardemone et al. Close Combat9 and its sequel Close Combat use a To this date, the tuned fuzzy controller still outperforms other FuSM that weights hundreds of variables through many for- controllers. Since Enemy Nations11 features AI-controlled enemies that em- the AI is applied to a well known game, it is easier to find ploy finite and fuzzy state systems and a database of goals expert players to test it against.

In addition, a powerful AI ap- and tasks [36]. This requires the game AI to be extensible, a feature to determine what objects a Sim character can interact with that is found in only a handful of games. Fuzzy-logic controlled bots have been released for the game The Chronicles of Jaruu Tenk13 employs A-Life technolo- [34], with weapon and item selection controlled by fuzzy de- gies alongside heavy use of cascaded fuzzy state machines to cision making.

These controllers are taken as basis for com- provide behavior for its critters [36]. From the examples provided, we see that fuzzy logic in Pinto models fuzzy sensors as input to extended behavior net- games has been used successfully into the industry, although works in Unreal Tournament18 , another famous first person developers tend to not go further than simple inference en- shooter [26], while Acampora uses timed automata and fuzzy gines or FuSMs.

In We instead find a different situation in the research field, these contexts, fuzzy logic is usually chosen to model the where diverse applications of fuzzy logic and systems can be player or of a virtual opponent due to its power as a method found, although with less frequency than the more popular to model emotion.

This technology is a fascinating concept especially now that technocrats are creating systems that can think and do things almost like humans. Game AI, Some of those benefits have already been reaped with the weak AI.
