Assignment: Week 12 – Advanced LINQ & Inventory Management

Overview

In this assignment, you'll extend the ConsoleRPG project to implement an Inventory Management System for players. This involves using advanced LINQ queries to perform actions on a player’s inventory, including searching, sorting, and filtering items. You’ll practice LINQ skills to manage a collection of items and add functionality for using, equipping, and removing items.

Objectives

By completing this assignment, you will:

• Gain experience with advanced LINQ queries in C#.
• Implement an Inventory system for the player, where they can add, equip, use, and remove items from the inventory.
• Extend the ConsoleRPG game mechanics using Entity Framework and LINQ to interact with the inventory and items database.

Instructions

1. Setup Inventory Management:

   • Add Inventory to Player:
     • Create a property List<Item> Inventory in the Player class to hold a collection of items.
   • Add Inventory Methods:
     • Implement methods in the Player class for adding, using, equipping, and removing items from the inventory.

2. Add LINQ Queries for Inventory Operations:

   • Write LINQ queries to:
     • Search for an item by name: Display any matching items by their name.
     • List items by type (e.g., Weapons, Armor): Group items by type and display them accordingly.
     • Sort items: Provide options to sort items by:
       • Name
       • Attack value
       • Defense value
     • These should be grouped into a Sort submenu in the main menu to allow the player to select a sorting option.

3. Implement Inventory Actions in GameEngine:

   • Add methods in the GameEngine class to handle the player’s inventory actions, using LINQ to:
     • Display the inventory list with sorting and filtering options.
     • Equip or use items based on their properties (e.g., only equipping items with attack or defense stats).
   • Update the menu in MenuManager to allow players to:
     • Search for an item by name
     • List items by type
     • Sort items (with a submenu for choosing sort criteria)

   Here’s a sample menu setup in MenuManager for reference:

   Console.WriteLine("\nInventory Management:");
   Console.WriteLine("1. Search for item by name");
   Console.WriteLine("2. List items by type");
   Console.WriteLine("3. Sort items");

   • Under "3. Sort items," add a submenu for sorting criteria:

     Console.WriteLine("\nSort Options:");
     Console.WriteLine("1. Sort by Name");
     Console.WriteLine("2. Sort by Attack Value");
     Console.WriteLine("3. Sort by Defense Value");

4. Update Database Context:

   • Add sample data to the GameContext for various items (e.g., weapons, armor, potions).
   • Seed Database: Ensure the database is seeded with a list of items that players can find or use in the game.

Stretch Goal (+10%)

1. Inventory Weight Limit:
   • Implement a weight system in the Player class by adding a MaxWeight property.
   • Each item should have a Weight property.
   • Add validation to prevent players from adding items that would exceed their MaxWeight.
2. Advanced LINQ Queries for Weight Management:
   • Use LINQ to calculate the total weight of items in the player’s inventory.
   • Filter items that can be equipped based on the remaining weight limit.

Submission Requirements

• Submit your modified files:
  • Player.cs, GameEngine.cs, GameContext.cs, and any relevant files containing LINQ queries and inventory methods.
• Include a short write-up explaining your changes and how the LINQ queries enhance the inventory management experience.
