Unity AI State Machines

State machines are a simple yet powerful way to design AI.

They define how entities behave under different conditions.

What is a State Machine

A system where an entity can be in one state at a time.

Example states:

• Idle
• Patrol
• Attack
• Retreat

Transition Logic

Transitions happen based on conditions:

• Player detected
• Health low
• Time elapsed

Example Concept

switch(currentState)
{
    case State.Idle:
        Patrol();
        break;
}

Final Thoughts

State machines are ideal for simple and scalable AI systems.

Start simple, then expand complexity.
