During the last part of this little article series I mentioned how I used a queue in each state object to allow for continuous transitioning to occur. The reason for this is to allow for complex transitioning to occur. One example for this is a logo screen where it needs to fade in, stay on screen and then fade out again. Rather than relying on managing the states manually, we can add states on to a queue so they occur automatically.
There comes a time when simple state management just will not cut it anymore. I found this out while building up the code base for Thrust’s GUI library. As the objects on the screen became more complex, so did their states. This article covers a new way of thinking about an object’s state, a design that has been proven in Thrust (v1.x). The goals of this state system include the following:
This one is incredibly simple.
And there you go!
In this fourth [page, second post] installment of the MGS: Pong article series, I am going to cover how to draw a background for the game. Before I start, I should tell you that there will be two more articles: one for creating the menu system and one for pulling all the classes together. Okay, let’s begin! The background class (Background.cs) is incredibly easy to create. First we need some private members to draw the background.
In part one of the mini game article series, I am going to show you how to create a very simple Pong game from scratch. The tools you will need include Photoshop (or any other painting program such as Paint.NET or even MSPaint), Visual C# 2005 Express, and of course the Xna framework.
First we need to create our project, to give us a home base for all of our work. Go ahead and fire up C# Express and create an empty windows project. I am going to call mine MGSPong for lack of any imagination or any better title. Once the project has been created, add a folder called “Content” and then another underneath that called “Textures.” This is where we will store out art, no matter how bad it may be!
Hardware Instancing is an interesting topic that has quite a few uses. The idea of instancing is to use the hardware to generate transformed vertices to reduce draw call overhead. Now I know that sounded like a bunch of senseless technical jargon, and it was. In plain English, sometimes it is faster to let the GPU do all the work for us so the CPU can go off and do other work; and this is what Hardware Instancing does. This article covers how to setup a simple program that uses instancing to render a few rotating squares. Read the rest of this entry »
Now that you have created you First Game, it is time to actually start drawing something. Right? How do you expect to make a real game without drawing anything? This tutorial shows you how to use the SpriteBatch object to efficiently draw 2D items on the screen. In the end you will be experienced with rotations, scaling, sprites and sprite sheets. So let’s get started! Read the rest of this entry »
This tutorial is dedicated to those who are new to the world of XNA. After installing Visual Studio 2008 (or C# Express 2008), DirectX 9.0c, and Game Studio 3.0 (currently CTP), open up Visual Studio. If this is your first time opening the software up, it will probably ask you what kind of settings to use. I recommend C# settings, but don’t worry because the layout is completely changeable. Once the IDE (Integrated Development Environment) is opened fully, we can create our first game!
