Pizzatron

Pizzatron is a pizza-making application that allows users to create their own pizzas using a graphical user interface (GUI) and watch the progress of the pizza being made. This project showcases the use of various design patterns, including the Factory, Builder, and Observer patterns.

<h2>Requirements</h2>
<ul>
  <li>.NET Core 3.1 or higher</li>
  <li>Visual Studio 2019 or higher</li>
</ul>

<h2>Installation</h2>
<ol>
  <li>Clone the repository to your local machine using Git.</li>
  <li>Open the solution file (`Pizzatron.sln`) in Visual Studio.</li>
  <li>Build the solution by selecting <strong>Build Solution</strong> from the <strong>Build</strong> menu.</li>
  <li>Run the application by pressing <strong>F5</strong> or selecting <strong>Debug &gt; Start Debugging</strong> from the menu.</li>
</ol>

<h2>Usage</h2>
<p>When you run the application, you will see the main window with various pizza ingredients on the left and a pizza canvas on the right. To create a pizza, simply drag and drop the desired ingredients onto the pizza canvas. You can also remove ingredients by right-clicking on them.</p>
<p>Once you have finished creating your pizza, click the <strong>Order</strong> button to submit your order. You will then see a progress bar showing the progress of your pizza being made. You can cancel your order at any time by clicking the <strong>Cancel</strong> button.</p>

<h2>Design Patterns Used</h2>
<h3>Factory Pattern</h3>
<p>The Factory pattern is used to create the pizza ingredients. There is a base <code>Ingredient</code> class, and then specific ingredient classes derived from it (e.g. <code>Cheese</code>, <code>Pepperoni</code>, <code>Mushrooms</code>). The <code>IngredientFactory</code> class is responsible for creating instances of these classes based on user input.</p>

<h3>Builder Pattern</h3>
<p>The Builder pattern is used to create the pizza itself. The <code>PizzaBuilder</code> class is responsible for creating instances of <code>Pizza</code> based on the ingredients added by the user. The <code>Pizza</code> class has various properties (e.g. <code>Crust</code>, <code>Toppings</code>) that are set by the <code>PizzaBuilder</code> based on user input.</p>

<h3>Observer Pattern</h3>
<p>The Observer pattern is used to update the progress bar when the pizza is being made. The <code>Pizza</code> class is the subject, and the <code>ProgressBar</code> is the observer. When the <code>Pizza</code> class updates its state (e.g. from "preparing" to "baking"), it notifies the <code>ProgressBar</code>, which updates its value accordingly.</p>

Abstract Factory Pattern

The Abstract Factory pattern is used to create different types of pizzas. There is a base Pizza class, and then specific pizza classes derived from it (e.g. CheesePizza, PepperoniPizza, VegetarianPizza). The PizzaFactory class is responsible for creating instances of these classes based on user input.

Strategy Pattern

The Strategy pattern is used to change the behavior of the PizzaBuilder class based on user input. For example, the user can choose between a thin crust and a thick crust, which changes how the PizzaBuilder builds the pizza.
