private Texture2D CreateRectangle(int width,int height)
{
Texture2D rectangleTexture = new Texture2D(GraphicsDevice, width, height, 1, TextureUsage.None,
SurfaceFormat.Color);// create the rectangle texture, ,but it will have no color! lets fix that
Color[] color = new Color[width * height];//set the color to the amount of pixels in the textures

for (int i = 0; i < color.Length; i++)//loop through all the colors setting them to whatever values we want
{
color[i] = new Color(0, 0, 0,255);
}
rectangleTexture.SetData(color);//set the color data on the texture
return rectangleTexture;//return the texture
}

Now go to your LoadContent Method if you don’t know what that is then look for this line of code

protected override void LoadContent()

so inside that method( or inside the { and } ) add the following

myTexture = CreateRectangle(640, 480);//give it a width of 640 and a height of 480

And there we go, now when the the Game loads the Content it will create our lovely filled rectangle. Simple right?
Now to make sure the texture is in fact there you will have to draw it so lets go down to our Draw method( or protected override void Draw(GameTime gameTime) ) and below GraphicsDevice.Clear(Color.CornflowerBlue); add the following

spriteBatch.Begin();
spriteBatch.Draw(myTexture, Vector2.Zero, Color.White);
spriteBatch.End();

now run the game and you should see something like this

the final code is of course below

using System;
using System.Collections.Generic;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Net;
using Microsoft.Xna.Framework.Storage;

namespace DrawRectangle
{
///
/// This is the main type for your game
///
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;

Texture2D rectangle;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = “Content”;
}

public Texture2D CreateRectangle(int width, int height)
{
Texture2D rectangleTexture = new Texture2D(GraphicsDevice, width, height, 1, TextureUsage.None,
SurfaceFormat.Color);// create the rectangle texture, ,but it will have no color! lets fix that
Color[] color = new Color[width * height];//set the color to the amount of pixels

for (int i = 0; i < color.Length; i++)//loop through all the colors setting them to whatever values we want
{
color[i] = new Color(0, 0, 0,255);
}
rectangleTexture.SetData(color);//set the color data on the texture
return rectangleTexture;
}

}

spriteBatch = new SpriteBatch(GraphicsDevice);
rectangle = CreateRectangle(640, 480);
// TODO: use this.Content to load your game content here
}

///
/// UnloadContent will be called once per game and is the place to unload

protected override void UnloadContent()
{
// TODO: Unload any non ContentManager content here

this.Exit();

base.Update(gameTime);
}

///
/// This is called when the game should draw itself.
///
///

{
GraphicsDevice.Clear(Color.CornflowerBlue);

spriteBatch.Begin();
spriteBatch.Draw(rectangle, Vector2.Zero, Color.White);
spriteBatch.End();
base.Draw(gameTime);
}
}
}

Essentially all we have to do is create a MediaLibrary and get the desired source for it. Its really simple I promise.

First add this to your namespaces:

using Microsoft.Xna.Framework.Media;

now create a MediaLibrary variable


MediaLibrary mediaLibrary;


then in your Initialize or LoadContent() methods do:


mediaLibrary = new MediaLibrary(MediaSource.GetAvailableMediaSources()[0]);//get the first media source and use that


Now to play the music found in the media library simply do

MediaPlayer.Play(mediaLibrary.Songs); //play all songs in the media library


Simple right? As a note there can sometimes be more than 1 media source so if you want you can loop through all the available MediaSources with a simple foreach loop.
so for example that can be done like so:

foreach (MediaSource mediaSource in MediaSource.GetAvailableMediaSources())
{
if (mediaSource.MediaSourceType == MediaSourceType.LocalDevice)
{
mediaLibrary = new MediaLibrary(mediaSource);
break;//break out of loop
}
}

And thats it…nothing else to it extremly simple but just in case here is a general idea of what you should have.


using Microsoft.Xna.Framework.Media;
using Microsoft.Xna.Framework.Net;
using Microsoft.Xna.Framework.Storage;

base.Draw(gameTime);
}
}
}


Here is my basic wish list for the engine

1.Xbox 360 compatible and PC compatible with as little errors as possible.

2.Multi-Threaded.

3.Easy to use and extend

4.Be both 2D and 3D compatible…

Looks like I have quite the journey ahead! Even if I am unsuccessful at my attempt at least I would have gained some insight and experience to physics programming and then maybe I’ll try again later on..

IF i am able to I will post a video ASAPTechnorati Tags: XNA Physics, Physics

On another note: there are only 5 more days left till Novemember 19th!(see creators.xna.com )

It can be located to the right of the page your viewing.

Theres the page for it.Enjoy and leave feedback!

This should give plenty of time for you XNA developers to covert all of your projects to XNA 3.0 before releasing them to the public!

I must say I am quite excited about the new dashboard update.What do you think?

Finnally after using the Beta and the CTP we will be able to use the Fully stable Xna 3.0 on October 30th.

Don’t know what XNA is? then hop on over to creators.xna.com and join the fun!
