Here's how you can use logical reasoning to create realistic AI behavior in games.

This is sort of the main thing to think about. The question going right to "logical reasoning to create realistic AI behavior" is a little loaded since it assumes a particular set of genres. You might not want to have "realistic" behavior; think about how awful that would make most tower defense games. Or maybe that's the point of your particular tower defense game, you want a really smart opponent and that's the "hook" of your title, a way to stand out. Figure out your needs first, then commit to paper.

There is a meme about AI being nothing but if-else statements. This of course depends on many things. You can also use statistical models. For example, the more often you die, the lower the accuracy of your enemies. That's a real number, not an if-else statement. Or the further behind you are, the higher chance of getting a powerful item in the next chest.

Testing AI logic is not only vital to create a dynamic and realistic AI but also in creating a positive user experience. Developers should test mechanics, AI logic, and UI functionality in an area designed for such testing and not a level developed for a player. It is also a good idea to have the console display logs of values and previous interactions to confirm everything is working as intended.

Enhancing the players ability to understand what is happening is also vital when asking for feedback. Examples of feedback to help the player understand their environment include adding sound effects or visual feedback after a player has completed an action.

I mean, you better have someone (besides you, obviously) playtesting your game, and not just because you want the AI to be great...

Hay que ser muy cuidadoso al implementar IA para generar un comportamiento realista. Especialmente cuando generamos NPC’s y los transformamos de alguna manera en PCs (Playing Characters). El playtesting debe ser realizado no solo para que funcione, sino que además para que sea entretenido para alguien. En un principio esto va a ser novedoso, pero en solo meses ya no será novedad para un jugador que busca entretenerse y no tener que “trabajar” dentro de un juego. Es entretenido esto? Agrega valor? O puede ser un handicap para la experiencia del jugador promedio? Es importante que las pruebas vayan más allá de la mera funcionalidad y se concentren en el valor por minuto de juego del usuario.

Use logical reasoning to create realistic AI behavior in games by designing decision-making systems based on real-world principles. Develop AI algorithms that consider multiple variables and potential outcomes, mimicking human thought processes. Implement state machines or behavior trees to manage complex AI actions and reactions. Use rule-based systems and fuzzy logic to handle nuanced and unpredictable situations. Continuously test and refine AI behavior through iterative development, ensuring it responds naturally to player actions. By grounding AI in logical reasoning, you can create lifelike and believable in-game characters.
