Summary  
This chapter demonstrates how to implement a finite state machine to manage an entity’s behavior through defined states and conditional transitions.  

General domain of usage  
Game AI

- **Idle**: This is the default state where the enemy is not engaged in any specific action. From this state, the enemy can transition to other states based on certain conditions;
- **Get Attacked**: This state represents the enemy being attacked by the player. It triggers animations in response to taking damage;
- **Follow**: If the player is within range but not too close, the enemy will follow the player, maintaining a certain distance to engage in ranged combat;
- **Dash**: This action involves the enemy quickly moving in a specific direction;
- **Projectile**: If the enemy decides to engage in ranged combat, it may launch projectiles towards the player;
- **Attack**: This represents a generic attack action that the enemy can perform while in close proximity to the player;
- **Attack2**: Similar to the "Attack" state, this is another type of attack action that the enemy can execute during close combat;
- **Idle After Finishing**: After performing any action (whether it's attacking, dashing, or launching projectiles), the enemy will return to the idle state to await further commands or player interactions.

### Conditions

- **Ranged**: This condition checks if the player is within a ranged distance from the enemy. If so, the enemy will enter the ranged combat mode, which includes actions like running, dashing, or launching projectiles at the player;
- **Close**: If the player is within close proximity to the enemy, it will enter close combat mode. In this state, the enemy will primarily focus on attacking the player with close-range attacks, such as attack1 or attack2.

Get ready to build an awesome fighting game featuring cool animations and a big boss battle! 
Learn Unity's animation system to create smooth player movements and powerful attacks.
Dive into enemy AI, shaping their behaviors from following to rage states. Improve your game with simple UI elements, cool effects, and sounds. Finally, share your game with others to play it.

In this chapter, we will learn all about animations, how to synchronize animations with movement, and how to smoothly transition between animations.


We will create a full behavior for the player and animate it. The player will be able to move, jump, and attack using different techniques, such as the Rigidbody2D for movement and triggers for attacks and interactions.

We will create the Boss AI and define its behavior based on the player's proximity. When the player is at a long distance, the Boss will either send a projectile or move toward the player. If the player is nearby, the Boss will attack with its weapon. Additionally, when the Boss's health drops below 40%, it will enter a rage state and unleash different, more aggressive attacks.

We will implement major improvements to the game, including adding particles and effects to enhance the overall feel. Additionally, we'll create UI elements such as the main menu and health bar, and ensure they are controllable. Finally, we'll export the game and test it.

We will revisit the game we created in the previous Unity course (Flappy Bird) and enhance it. We'll add random generation, synchronize the background movement with the player, and dynamically move obstacles, creating an endless gameplay experience.
