Polymorphism issue - virtual fields? (C#)
Hello, I have problem with class design. I have core class for my game objects. While drawing I need to retrieve position from the object. Unfortunately object is seen as it's base type so the position is not retrieved from derived class but from it's parent. Defining field as virtual would fix my problem, but it's impossible :(. How ca...
C# polymorphism question once again - overriding fields?
Hello, This time I have problem with virtual fields. I have core class for my game objects. This class contains a field with Model class object.

Recommend sprite size for games (XNA)?
What is the best size for an individual tile in a 2D sprite sheet? I am creating a sprite sheet and am trying to figure out what the best resolution is to use for each sprite.

Developing 2D in 3D with orthographic projection and stretched model
I was wondering if there is any benefit to using an orthographic projection camera, to make a 2D game with 3D models (as opposed to making sprites and using 2D). Also, on a related note when I use orthographic projection, my 3d-model is stretched. Does anyone know why this is happening? I know that aspect ratio only influences the persp...
LoadContent does not work in my components
For some reason the LoadContent method does not get called in my Components.

Store data in C# source files vs. XML etc...?
This is a C# question. I was just wandering if anyone tried storing their data (like config files for example), in the *.cs file, instead of XML? I really hate XML. The whole idea of parsing html-like structure every time you need some data seems stupid. Are there lightweight alternatives (like YAML) to XML? In my case I actually need...
Passing "this" as an argument - C#
Hey I'm currently playing about with some XNA stuff learning to program AI. Anyway, here's my situation: Class A has a function which takes a reference to an instance of class B, does some stuff to to it, and returns it. Class B contains an instance of Class A, and then calls the function from it. Example in code: Class A { B clas...

Where do I put my custom Levels folder in XNA game?
I am quite lost with where and how to store the *.txt level files in my game. What I want in my game is the availability of a few "prebaked" levels that come installed with the game but also the ability for users to create their OWN levels. So what I did is created a new directory inside visual studio in the "Content" called levels, an...
How to write a simple .txt content processor in XNA?
I don't really understand how Content importer/processor works in XNA. I need to read a text file (Content/levels/level1.txt) of the form: x x x x x x where x's are just integers, into an int[,] array. Any tips on writting a SIMPLE .txt importer??? By searching google/msdn I only found .x/.fbx file importer examples. And they seem t...
looking to hire a XNA developer, where should I look?
I am developing a game in which the logic is written but the visuals are not. Although the graphics are drawn, I need a way to get this graphics onto the screen to be manipulated, as well as a menu system. No one in my small three man dev team has experience with XNA and thus I am worried we will not make our intended deadline. Is the...
XNA project - who is in charge of drawing?
I am just playing around with XNA, and I have several different models I need to draw in each frame. at the moment, the Game object holds references to all my models, and draws them one after the other. Each with his own different way of drawing - one has two separate textures, the other might be mirrored to the other side, etc. I was w...
Is it possible to write a commercial XBOX game using Visual Studio and MS XNA Game Studio SDK?
I know most commercial games development is done in assembly or C/C++ but has anyone tried using XNA with VS 2008 to create a real time intensive application that would be fit for release in the high street as oppose to just on XBOX Live. What are the limitations you encountered and what sort of frame rates were you getting and in what r...
Dynamically alter or destroy a Texture2D for drawing and collision detection
I am using XNA for a 2D project. I have a problem and I don't know which way to solve it. I have a texture (an image) that is drawn to the screen for example: |+++|+++| |---|---| |+++|+++| Now I want to be able to destroy part of that structure/image so that it looks like: |+++| |---|---| |+++|+++| so that collision now will work ...
Unit testing XNA: Do I need to Mock my GraphicsDevice
I'm fooling around with the XNA framework. To help me around I made a helper class that looks like this: ActorHolder + SpriteBatch (SpriteBatch) + ContentManager (ContentManager) - drawables (IList<IDrawable>) - updatables (IList<IUpdatable>) + ActorHolder(GraphicsDevice, ContentManager) + Draw(GameTime) + Update(GameTime) + AddActor(I...
