This is the Challenge called ChallengeSimpleDarts, designed to test your knowledge of the lessons covering Classes and Class Libraries. If you need to review these concepts, refer to the Cheat Sheet or review the previous lessons. You will be required to create a simple game of darts, that consists of two players throwing darts at a board and keeping track of their score.


Detailed instructions for this challenge will be located in a text file within the CS-ASP_045Challenge_Code folder. The basic challenge is to create a simulated game of darts, where simulated players take turns throwing darts at the dart board until one player reaches 300 points. In case you're not familiar with the game, the illustration below explains the basic scoring mechanics:


There are different sections on the board numbered 1-20 that each have a double and triple ring on them. These rings double or triple the score, respectively, of the section they belong to. In a game of darts, the player throws a dart at the board, and adds to his current score whatever his dart hit. For instance, if the dart landed on the outer (double) ring of the 13 section, he would add 26 (13 * 2) to his score. In addition to this, the circle in the center of the board is the bullseye. It consists of an inner and outer band. The outer band is worth 25 points, while the inner is worth 50.

Because this is a simulated game, the dart will have a random chance of landing on any of the 21 sections (1-20 and bullseye). You will create a re-usable library called Darts that could be used for other dart games in the future. It will contain a single class named Dart. When creating a new instance of Dart, you will pass it an instance of the System.Random class to ensure you get a true random number across the lifetime of the web page's lifecycle. When you call the Throw() method it will simulate the act of throwing a dart at a dart board.

You will need to create a Game and Score class also to manage the game logic and score, and their purpose will be explained in the Challenge-Requirements.txt document.

When your project is finished, you should have a Web Form that looks like this:


The web page should include a button and a label that displays both the players' score and which was the winner of the game. Do your best to keep all your methods cohesive and as short as possible (ideally 6 lines or less). That is a bonus requirement, but it is also a good practice to get into.


This challenge is complex due to the separation involved with different classes, but if you thoroughly review the content we've covered this far, it should be doable. Review the detailed instructions attached in the .txt file for the full directions, as well as some images to help you out. As always, if you run into a problem, the solution is available for you to review. Good luck!
