Character Pink Girl? XNA 4.0? This could be your first Windows Phone Program
I have put together a really simple example of using XNA 4.0 in the Microsoft Visual Studio 2010 Express for Windows Phone CTP (MSV2010EWP? Nope, let’s use Phone CTP)
To get started, download the ABSOLUTELY no cost Phone CTP from:
You download some of the other excellent samples from MSDN, but you just need to the Phone CTP for this example. This is a simple example:
Open a new project:
Name the project: PinkGirlAppears, or similar
Click OK
You will see a game program appear, this is like XNA 3.1 if you have used the earlier versions of the XNA Game Studio. However, you can’t utilize projects you created in XNA 3.1 because they won’t convert directly. There are some differences in how content is handled, positive changes. You will need to add an image named PinkGirl to make this work.
You do this by adding the image in the new Content Project, here are the two steps:
Right click and select Existing Item, navigate to a folder with some images
or use the one included at the bottom of blog:
Your image filename will appear here, in place of Character Pink Girl.png
Now, change the “asset name” properties of Pink Girl so that the code will pick it up (if you don’t do this, your code will not run):
Open the Game1.cs (Game1 Class) delete all of the code in that file by using ctrl+A and then Delete.
Now copy the following and paste it into the empty Game1.cs class, press F5, wait a few seconds, and then a few more seconds, then a Phone should appear. This is the Windows Mobile Phone Emulator, and Pink Girl should appear!
