Applications of AI and ML in Game Development

Building on the foundational understanding of AI and ML, we can explore how these technologies are applied in game development. The integration of AI and ML has revolutionized various aspects of games design, from creating more realistic and engaging NPCs to automating content generation.

Dynamic Difficulty Adjustment

Dynamic difficulty adjustment is one of the most impactful applications of AI in game development. AI algorithms analyse a player’s skill level and behaviours in real-time, adjusting the game’s difficulty to ensure it remains challenging yet enjoyable; it can prevent frustration from overly difficult levels and boredom from levels that are too easy. This approach helps maintain player engagement, and overall satisfaction with the game.

An example of this application can be seen in the popular game FIFA. In FIFA, machine learning is used during the Career Mode to analyse player performance and adjust the opponent’s AI. For instance, if a player consistently performs well the ML algorithms may increase the tactical complexity and responsiveness of the opposing teams, making matches more challenging. Alternatively, if a player is struggling the game can adjust to provide more balanced and accessible gameplay.

Procedural Content Generation (PCG)

Procedural content generation involves using AI and ML algorithms to create game content (levels, landscapes, items) automatically. This technique allows for the creation of vast and unique game worlds without requiring extensive manual input from developers. PCG ensures that each player’s experience is distinct which offers endless possibilities and replay value. This automation of content creation not only saves time but also adds a layer of uniqueness to each gameplay experience.

No Man’s Sky is a great example of PCG. Procedural generation is used to create a virtually infinite universe of unique planets and ecosystems. Each planet in the game is generated by algorithms, the procedural generation system creates unique terrain, flora, fauna and weather patterns in real-time, which means no two players have the same experience. This approach allows for an expansive and diverse game world that encourages exploration and discovery.

Non-Player Character (NPC) Behaviour

AI-driven NPCs exhibit realistic and complex behaviours which makes interactions with players more engaging and challenging. Advanced AI algorithms enable NPCs to make decisions based on play actions and environmental factors, leading to more immersive and unpredictable gameplay. This level of sophistication in NPC behaviour enhances the depth and realism of the game, in turn making the experience more compelling for players.

In The Last of Us Part II, for example, NPCs use AI to react dynamically to player’s actions. NPCs can communicate with each other, formulate strategies, and adapt to the player’s tactics. During combat, if a player is detected by an NPC, that NPC can alert nearby allies who will then coordinate their movements to flank and trap the player. This creates a lifelike and responsive gaming environment making interactions with NPCs more meaningful and adds a layer of strategic depth to the game.

Player Behaviour Analysis

Machine learning algorithms analyse player behaviour to provide insights into engagement, preferences, and potential churn. This data helps developers refine gameplay and marketing strategies to better meet the players’ needs and enhance retention, thus increasing player satisfaction and loyalty. This analytical approach allows for continuous improvement and personalisation of the gaming experience.

Games like PUBG use ML to analyse player interactions and tailor experiences accordingly. By examining patterns in player behaviour, the game can adjust elements such as matchmaking, content recommendations, and in-game events to better suit player preference ensuring a more engaging and satisfying experience.

Fraud Detection

Ensuring a fair and secure gaming environment is critical, and AI and ML play a significant role in detecting and preventing cheating, hacking, and fraudulent activities. AI systems can monitor player behaviour and identify anomalies that may indicate cheating. This ensures that all players have a fair experience and maintains the integrity of the game.

For instance, Riot Games uses machine learning in League of Legends to identify toxic behaviour and prevent in-game fraud. By analysing chat logs and player actions the AI can detect and address issues such as cheating and boosting, as well as offensive language or unsportsmanlike conduct. The AI can then take appropriate actions such as issuing warnings or temporary bans.

Real-Time Translation

ML algorithms provide real-time translation of in-game text and voice chat which enables seamless communication among players from different linguistic backgrounds. This feature is particularly beneficial in multiplayer games, where effective communication is key to teamwork and success. Real-time translation enhances the social aspect of gaming, making it accessible to global audiences and encouraging diverse player interactions.

Minecraft is a great example of this. In its multiplayer serves, players from all over the world come together to build, explore, and collaborate, which makes it important for players to be able to discuss strategies, share resources and coordinate actions. With real-time ML-based translations a player speaking Spanish can seamlessly communicate with another speaking English, ensuring that instructions, ideas and feedback are clearly understood by everyone.

How AI and ML will revolutionise the way you develop your games

As we’ve seen, AI and ML are already making significant contributions to game development, however, their potential extends far beyond the current applications. These technologies are set to revolutionise the industry even further, driving advancements that will shape the future of gaming. But how is this going to impact your game development in the future?
