A key part of many contemporary video games is combat, often a fight with an intelligent adversary. This requires an AI that can improvise and react in real time, which is often a challenge. One way this is done is through Behaviour Trees, which allow developers to create the AI’s decision-making process by defining tasks, sequences and selectors. For example, if an enemy notices it is low on health then it could act in a certain way, such as running away or calling for reinforcements.
Reinforcement learning is luxury111 rtp common technique for game AI, which enables nonplayer characters to adapt their behavior based on feedback from the player. This can be used to make enemies more unpredictable – as seen in the Alien: Isolation Xenomorph, which learns from the player’s behavior and adapts its strategy, making it harder to evade.

Generative AI is also popular in games, allowing the creation of vast and ever-changing worlds, for example in Minecraft and BioShock. This can also be a powerful testing tool, giving developers detailed metrics and visualizations of how well their game performs against the players, helping them fine-tune the experience faster.
However, Chris Knowles, an indie developer at UK studio Sidequest Ninja, has concerns about generative AI. He says that online storefronts are already rife with “clones” of original titles, and says that generative AI can help these clone studios achieve profitability more quickly than would be possible without it. He also highlights the huge amount of power that it takes to run these algorithms, which he believes will become an obstacle for smaller indie developers who aren’t able to afford the electricity bills.
