There are two very common techniques used to create AI: the finite state machine and the behavior tree. Depending on the game that you are making and the complexity of the AI that you want, the technique you use will vary. In this chapter, we'll utilize both the techniques in our AI script to maximize the potential of our AI.
Finite state machines are one of the most common AI systems used throughout computer programming. To define the term itself, a finite state machine breaks down to a system, which controls an object that has a limited number of states to exist in. Some real-world examples of a finite state machine are traffic lights, television, and a computer. Let's look at an example of a computer finite state machine to get a better understanding.
A computer can be in various states. To keep it simple, we will list three main states. These states are On, Off, and Active. The Off state is when the computer does not have power running it, the On state...
