Dynamic enemies with sensors and behavior trees
In video games, sensors can play a crucial role in creating interactive and dynamic AI behaviors. They enable NPCs to perceive their surroundings, allowing them to react to not only the player but also other environmental things in a more realistic manner. For example, in stealth games such as Metal Gear Solid, enemies are often equipped with a field of view (FOV) sensor that detects the player when they enter their line of sight. Similarly, games such as The Last of Us incorporate audio sensors that enable enemies to detect the player based on noises they make. These types of sensors add depth to the gameplay by having players change the strategy of their movement and actions more carefully.
In short, sensors are abilities added to our objects that make them aware of their surroundings and other objects – especially true concerning an enemy NPC and the player!
In this section, we’ll look at some code that can be used...
