[C#][Textbased] Command System, input needed.

Victor Karlsson · 2011-07-11T23:21:41

Hello all! I'm currently working on a small RPG-style text adventure game. Hold on now! It's not an epic long game of 60+ gameplay hours. It's a very very small ( still complex though ) text based RPG that has 3 classes which each offers around 20 minutes of gameplay. Anyways, the game features a very very basic command-system that has the identifier of '/'. Some examples are: /pickup, /talk, /climb, /attack, /open ect ect. I'm sketching on a small prototype of it using delegate's and .Invoke. This is what i have so far: public class Command { Delegate Invoker; public Command(Delegate function, cSystem caller, string[] args) { Invoker = function; Invoker.Method.Invoke(caller, new object[] {args}); } } public class cSystem { Command a; delegate void Method(string[] args); private void Test(string[] args) { Console.WriteLine("Hello World, {0}"); } public cSystem(string[] args) { a = new Command(new Method(Test) , this, args); } } class Program { static void Main(string[] args) { string[] StringArray = new string[1]; StringArray[0] = "By Victor"; cSystem b = new cSystem(StringArray); Console.ReadLine(); } } This is really sweet since Command's can access even the private functions of the cSystem. The idea is that cSystem is the main-game class, it contains everything, character, command-lists, location-lists ect ect also all of the functions the commands are going to use when triggered. As you can see the above example isn't really developed THAT much but it works and you can feed another class functions from the calling class ( cSystem ). My idea is to have ( ONE ) instance of each command-type in a dictionary, this way when a location or anything else needs access to the command i don't need to create a new instance of it, i can add it to a List<Command> CommandList = new List<Command>(); that holds refrences to Command-objects like so: CommandList.Add(caller.FetchCommand(Commands.Open)); So input anyone? Is this a good implementation?

Yeah, I get that I need some kind of "Editor" ( Monster Editor, Item Editor ect ect ) to create the serialized files ( It needs to have the same .cs files as the main game ).
Then I can simply add them all in the main-game, de-serialize them and use them ingame!

But how do you parse ( that is the name for it right? ) Dialogs , AI's and such? Or do you make a Dialog.cs and AI.cs that contains the Dialog and Logic for the Dialog? add it to the NPC and serialize it all together?
Is that how it commonly works?

( Of course all that is done with the "Editor" )

3dbuzz got a free video tutorial on how to make an engine for text based adventure games in c#. I know its not exactly what you are looking for but it got som very good tips on handling input.

I have actually seen that one ( Not watched all the videos though ).
And It's a great reference source!

But all in all, my biggest question ( right now ) is how to implement larger entities without hard-coding them all.
By the information I have gathered, reading from a ( database ) file and parsing the strings into objects or serialize/de-serialize files directly into objects.

How do you create a big entity and serialize it, like for example an NPC-entity? With a dialog's that have logic ( and or else if ), call functions that changes different status and the likes, or hold a huge text-dialog.
Monsters with different AI's, Items that differs from normal ones, that calls a function each time it is used in battle and so on.

I know Scripting comes to many of you readers minds, but then i would have too add Lua ( or Python w/e ), and miss the knowledge of how to do these stuff by natively-coding them!
I'm a beginner but I want to learn!

Hope you GameDev-foxes can give me quick run through about the theory behind it all!
