Summary  
This chapter demonstrates how to manage discrete behavior states and transitions by setting boolean and integer parameters and controlling transitions programmatically based on user input and current state.  

General domain of usage  
Game development

### Attack Type
To inform our animator of the desired attack, we need to create different attack types and assign each type an integer value.
For the first ability, the attack type will be `0` and for the second ability, it will be `1`.

### Control the Attack Type with Script
```csharp
void Update()
{
    if (Input.GetMouseButtonDown(0)) // Left mouse button
    {
        animator.SetInteger("attackType", 0);
        animator.SetBool("isAttacking", true);
        isAttacking = true;
    }
    if (Input.GetMouseButtonDown(1)) // Right mouse button
    {
        animator.SetInteger("attackType", 1);
        animator.SetBool("isAttacking", true);
        isAttacking = true;
    }
    if (Input.GetMouseButtonUp(0) || Input.GetMouseButtonUp(1)) // Any mouse button released
    {
        isAttacking = false;
        animator.SetBool("isAttacking", false);
    }
}
```

The code handles attack states by setting different `attackType` values and updating the `isAttacking` parameter based on mouse button presses and releases, allowing for distinct attack actions and their termination.


Overall, this code handles attacks in a game, distinguishing between left and right mouse button presses and releases. It sets the attack type since every button will have a different attack, and updates animator parameters accordingly. When either button is released, it stops the attack animation.

What is the purpose of the `attackType` parameter in the code that we did?


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.
