What you have been writing so far were top-level statements. And while they are just fine for learning and writing simple scripts, for more complex behaviour it is easier to use classes.

If you want to have scripts for multiple heroes, every hero has to have a class named after him that inherits from the base class AutomaticHero.

Classes

A class is a template that describes the behaviour of a an object.

// This is a class that represents all behaviour of your bot.
// It's name is MyHero (name of your hero) and it inherits its behaviour from the parent/base class AutomaticHero (inheritance will be covered later) 
class MyHero : AutomaticHero
{ 
    // Curly brackets define the boundaries of your class. 
    // All the code that describes your bot’s behavior will go inside these braces.
}

Warning

Name of your hero class must match the name of your hero in game

Methods

Class contains methods. Methods are blocks of code that perform a specific task.

Let's start editing your bot and make it say "Hello World" when it starts.

Method declaration

First you need to declare a method. Give it a name, specify the return type and parameters (if any) and write the code inside the method body in the curly braces.

Note: This method doesn't need to return any value, so the return type is void. It doesn't take any parameters, so the parentheses are empty. This will be covered later

Method call

When you want to execute the code inside the method, you need to call it using it's name followed by parentheses. If the method takes any parameters, you need to pass them inside the parentheses as argument1, argument2, ....

Every statement (line of code) in C# ends with a semicolon ;.

class MyHero : AutomaticHero
{
    // This is a declaration of a method called Awake, a sequence of code. A code from inside the game will call this when the bot is started. Any code you put here will be executed then.
    void Awake()
    {
        // block of code surrounded by curly brackets, everything in here belongs to this method, the code runs sequentially from top to bottom   
        Say("Hello World"); // Call a method Say, this method is implemented in the base class AutomaticHero, we are passing a text string as an argument
    }           
}

When you call method that has parameters declared like Say(string) you need to pass the argument inside the parentheses. In this case we are passing a string "Hello World". A string is a sequence of characters enclosed in double quotes, used to represent text.

Note: You can call the method Say even though you haven't declared it, because it's declared in the base class AutomaticHero.

Static Classes

In some cases you don't need to have multiple instances of some classes, these classes usually represnt some sort of utility or helper classes.

In this game we have a static class Hero that represents your current hero. You can call methods on this class without creating an instance of it by using the class name Hero.
