1. I’ll be sure to seek your advice if I run into anything else, thank you for your help Scott.

2. Scott, with your help, I’ve created an RPG in Windows Forms and would love for you to tell me what you think!

   You can download the executable from the following link.

   Thank for for all your great tuturoials!

   1. Cool! I’ll check it out this weekend.

3. Unfortunately I got to this point and it all went wrong.

   Cutting and pasting the code from Git caused unrecoverable code errors in the generated form code. I had an error message saying that I had not created a method for rtbLocation_TextChanged.

   I could not find a way past this and it is either a choice of giving up or starting all over. Not a fan of starting all over. 🙁

   1. What lesson did you get to? Can you upload your solution (including the directories under it, and all the files in those directories) to GitHub or Dropbox, so I can look at it?

4. Hi Scott,

   I just wanted to say immensely grateful I am that you have created and shared this walkthrough/guide. I am not finished yet, but I am rolling along with it. I have wanted to learn computer programming for some time now. Your book has really inspired me to do it. Are there any other guides you’ve made like this one? Programming other various games to further learn C#?

   Thank you for reading,
   Dan

   1. Thank you Dan,

      I don’t have PDF versions for anything else. But, I do have lessons on C# Design Patterns (general solutions to common programming issues), a WPF version of the SuperAdventure game (that uses better programming practices than the Windows Form lessons), and just started a new “refactoring” series where I will be improving the code quality of the Windows Form SuperAdventure game – and describing how/why the changes will improve SuperAdventure’s quality.

5. Semi-Novice here but… I was able to add Armor items that add additional defense during battles (including a function to ensure that the defense amount is never less than zero resulting in negative damage being done):

   Armor.cs:
   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   using System.Threading.Tasks;

   namespace Engine
   {
   public class Armor : Item
   {
   public int MaximumDefense { get; set; }

   public Armor(int id, string name, string namePlural, int maximumDefense) : base(id, name, namePlural)
   {
   MaximumDefense = maximumDefense;
   }
   }
   }

   —–

   Example items:
   Items.Add(new Armor(ITEM_ID_SHIELD, “Shield”, “Basic Shield”, 4));
   Items.Add(new Armor(ITEM_ID_LEATHER_CHEST, “Leather Chest”, “Basic Leather Chestpiece”, 8));

   —–

   damageToPlayer int calculation:
   int damageToPlayer = CheckIfLessThanZero((RandomNumberGenerator.NumberBetween(0, _currentMonster.MaximumDamage) – RandomNumberGenerator.NumberBetween(0, defParse)));

   —–

   Zero check:
   private int CheckIfLessThanZero (int input)
   {
   if (input < 0)
   {
   return 0;
   }
   else
   {
   return input;
   }
   }

   Happy to share the code with everyone or even work with anyone to make this a little better than a novice could add.

   1. Thanks for sharing Chris!

      In the damageToPlayer calculation, is “defParse” from the MaximumDefense property of the player’s armor?

      There’s also a cool trick you can do with the CheckIfLessThanZero function. There is a Math.Max function that will accept a list of integers and return the largest value. So, the function below will return 0 when “input” is less than 0. Otherwise, it returns “input”.
      private int CheckIfLessThanZero(int input)
{
return Math.Max(0, input);
}

      1. Yes it’s from the MaximumDefense property in the armor, parsing into an int for the function (I may have overthought that a little bit and there is likely an easier way to get the value.)

         Will update the Math.Max function. A lot easier to code that way.

         1. Because the MaximumDefense property is an “int”, it should always have a value – it defaults to “0”. So, you should be able to use it without any parsing.

6. When I got to lesson 11.1 and copy/paste the World.cs static class into my game I got 18 errors that were all similar to this:

   CS1061 ‘Quest’ does not contain a definition for ‘RewardItem’ and no accessible extension method ‘RewardItem’ accepting a first argument of type ‘Quest’ could be found (are you missing a using directive or an assembly reference?)

   Is this expected?

   Reply

   1. That error message is saying the Quest class does not have a RewardItem property.

      Check your program’s code with the code in Lesson 10.1 – especially the code for the Quest class in step 4. Make sure the RewardItem property exists, its datatype is Item, and it is public.

      If that doesn’t fix the error, can you upload your solution (including the directories under it, and all the files in those directories) to GitHub or Dropbox, so I can look at it?

      1. My solution is located at: https://github.com/PretendObject/SuperAdventure

         1. The errors are all related to name differences.

            In the Quest class, the property “RewardItem” is typed as “Reward Iten” (an “n”, at the end, instead of an “m”). In the Location class, the “LocationTo” properties are named “LocationToThe” (with an additional “The”).

            That is a common reasons for this error message. It also happens if a property is not public, and you try to reference the property from a different project – the default is “internal” (only visible inside the same project), if you don’t explicitly add “public”, “private”, or “protected”.

            Let me know if that doesn’t eliminate the errors, or if you have any questions about the solution.

7. Scott Lilly you are awesome! Thanks for catching my typos and wrongly named variables!
