Creating a Game Using Microsoft’s Next Generation Technologies (lvl. 300) Tamir Khason and Alex Golesh [email_address] | [email_address]

In 1 hour we will try to create…

The Street Racing Game

… which is network multiplayer game

… that runs on XBOX

… and personal computer

… with WPF

… in web browser (later iSmoke will come)

… also it runs on Linux

… and on mobile phone

Now the time for…

… with WPF

XNA Framework Overview Core Framework Graphics Audio Input Math Storage Extended Framework Application Model Content Pipeline Games Starter Kits Your Code Your Content Components Platform DirectX XDK .NET Framework .NET CF Networking Gamer Services Networking Gamer Services

Let’s see XNA application creation

Game Theory Level Level Level Level Level Load Content Update Draw

XNA Game

Main game class should derive from Microsoft.Xna.Framework.Game

Class constructor should initialize graphics and other components game need

Networking – Session Creation

Graphics Networking Components Audio Gamer Services

LoadContent/Update/Draw

LoadContent

Update (occurs 60 times per second)

After this stage Draw being executed

Now the time for…

… with WPF

Now, we’ll make it better Core Framework Platform DirectX XDK .NET Framework .NET CF Networking Gamer Services WPF Base Services User Interface Services Audio Input & Eventing Accessibility XAML Data Binding Layout Controls Application services Deployment services Data LINQ XLINQ

XNA Part harvesting

Add XNA references

Wrap Game class

Check whether the player is logged in

… and show login panel if not

Seek for active session

… and join it when found

XNA Part transplantation

Create new game instance

XNA services and components

Subscribe to game events

Run the game

XAML/WPF implantation

Create regular WPF Window

Create vector map and car

Bind to resources

And handle user’s input

WPF implantation

Create data dependency object, wraps XNA transplants

Mark roads on XAML vectors

Now we can find it by using LINQ

And even check bounds

Let’s see it running as WPF application with XNA implants

Now the time for…

… with WPF

But I want it anywhere! Core Framework Platform DirectX XDK .NET Framework .NET CF Networking Gamer Services WPF Base Services User Interface Services Audio Input & Eventing Accessibility XAML Data Binding Layout Controls Application services Deployment services Data LINQ XLINQ

WPF Parts harvesting

Harvest XAML “as is”

Add small Silverlight

Put it into ASP.NET AJAX page

… and connect it to XAML based “server”

ASP.NET AJAX implantation

Create Web Method to return current players list

Access the method from ASP.NET page with circular timer

… and update current players’ positions in XAML scene

Silverlight 1.0 implantation

Create XAML object in JavaScript

Create and add it to the Silverlight scene

… and update it’s properties from JavaScript, based on server side variables

Let’s see it playing together

Will it blend on… ?

Now the time for…

… with WPF

Let’s see the game on … Linux

Now the time for…

… with WPF

… and now on … mobile phone

Now the time for…

… with WPF

At the end – what others do?
