Time for action – creating an application

Open Terminal again and follow these easy steps:

1. You should have the path to the Cocos2d-x console already added to your system. You can test this by using the cocos command inside Terminal. In order to create a new project called HelloWorld, using C++ as its primary language and save it on your desktop, you need to run the following command, replacing YOUR_BUNDLE_INDETIFIER with a package name of your choice, and replacing PATH_TO_YOUR_PROJECT with the path to wherever you wish to save your project:

   cocos new HelloWorld -p YOUR_BUNDLE_IDENTIFIER -l cpp -d PATH_TO_YOUR_PROJECT
   

2. As an example, in my machine this is the line I typed:

   cocos new HelloWorld -p com.rengelbert.HelloWorld -l cpp -d /Users/rengelbert/Desktop/HelloWorld
   

   And hit Enter. If you choose not to give a directory parameter (-d), the Cocos console will save the project inside the Cocos2d-x folder.

3. Now you can go to your desktop, or wherever you chose to save your project, and navigate to the folder proj.ios_mac inside the HelloWorld project. Inside that folder you'll find the Xcode project file. Once you open the project inside Xcode, you can click the Run button and you're done.
   

Note

When you run a cocos2d-x application in Xcode, it is quite common for the program to post some warnings regarding your code, or most likely, the frameworks. These will mostly reference deprecated methods or statements that do not precisely follow more recent and stricter rules of the current SDK. But that's okay. These warnings, though certainly annoying, can be ignored.

What just happened?

You created your first Cocos2d-x application. The parameters used on the command line are:

• -p for package or bundle identifier
• -l for language, and here, you have the option cpp, lua, or JavaScript

Now let's run this app in Android.
