Creating a new project

Use the following steps to create the project:

Press Windows + R and type in cmd.
On the command prompt, type in the following command and press Enter:
```
cd desktop\coco2d-x-2.2.3\tools\project-creator
```
In the project-creator folder, type in the following command and press Enter:
```
python ./create_project.py –project wp8Game –package com.testpackage.wp8Game –language cpp
```
You will be presented with the screen shown in the following screenshot:
Note
Once the project is created in the project folder, you shouldn't move the folder around as it will lose the references to Cocos2d-x and the folder required to run the game.
Now navigate to the project's folder in Cocos2d-x-2.2.3. You will find the new folder created, named wp8Game. Double-click on it and you will see the folder structure, shown as follows:
You can see a Classes folder, a Resources folder, and project folders for all the different platforms that Cocos2d-x supports.
Since we are making a game for the Windows Phone platform, double-click on the proj.wp8-xaml project folder and double-click on wp8Game.sln.
When asked for application preference, choose the Windows Phone option. This will open the project in Visual Studio, as shown in the following screenshot:
To run the project on the emulator, select Emulator WVGA 512MB and click on the green play button. This will take some time to build; once built, the project should run on the simulator, as shown in the following screenshot:

Congratulations on creating a new project! Now that the project is created, let's take some time to understand the fundamentals of the coordinate system and the basic classes used in Cocos2d-x that serve as the building blocks for creating any game.
