Preface
The PlayStation Mobile SDK presents an incredible opportunity for developers to easily and affordably create and sell applications for the PlayStation Vita, as well as a number of PlayStation certified devices. This represents the first time it has been possible to write applications for a console quality portable device without first having to spend several thousands of dollars on professional development kits.
It includes all of the tools you require to successfully create a game, including a complete Integrated Development Environment (IDE), a C#/Mono based compiler and runtime, as well as the tools and utilities required to create interfaces and import game assets. The SDK is suitable for a range of developers, from hobbyists to Indie game developers as well as AAA game studios. A number of large studios, including From Software, Gameloft, and Sega, have announced their support for PlayStation Mobile. To date, a number of titles have already shipped and are available in the online store.
A tour of the PlayStation Mobile SDK
We will now take a quick tour of what is included in the SDK; if you haven’t already, download it from the PlayStation Mobile Developer Portal at https://psm.playstation.net/. The SDK includes the components that we will discuss now.
PSM Studio IDE
The PSM Studio is a complete IDE derived from the popular open source MonoDevelop project. It includes a complete code editor, project management system, and integrated debugger. It contains most features you would expect of a modern IDE such as unit testing, code completion, and refactoring.
Compiler and runtime
PlayStation Mobile is built on top of the Mono compiler and virtual machine. In addition to the PlayStation provided libraries, it includes the following .NET libraries:
In addition to those standard .NET libraries, Sony has provided the following libraries:
You can also make use of any existing C# code that does not require native access. We will look at each of these libraries in more detail throughout the book.
UIComposer
The UIComposer enables you to visually create user interfaces. It includes a comprehensive set of widgets including buttons, text fields, progress bars, flip panels, scrolling areas, and more. Ultimately UIComposer is a code generator that will output a .cs file that makes use of partial classes to keep your application logic separate from system generated code. If you are familiar with WinForms, this will be instantly comfortable for you. It is a drag-and-drop environment, enabling you to build your user interfaces in a visual manner:
Other utilities
The SDK includes a number of utilities for importing your various assets for use in your game. There is a command line based model converter for importing your 3D model into PSM’s native MDX format. There are also tools for importing Flash animations, and graphical shaders, as well as a tool for creating on-screen controllers for Android devices. Finally, there is the PublishingUtility, which is used to prepare your application for deployment to the online store as well as for creating downloadable content. Assuming a default installation, all these tools and more are located in the folder C:\Program Files(x86)\SCE\PSM\tools. We will cover many of these tools in detail later in the book.
PlayStation Mobile certified devices
PlayStation Mobile can target the PlayStation Vita, as well as a growing number of PlayStation certified devices. Currently this includes a number of Xperia mobile phones, Sony Android tablets, and a series of HTC phones. You can see a full list of certified phones at http://www.playstation.com/psm/certified.html.
It is hard to believe the level of technology being packed into these devices. Let us now see the specifications for the PlayStation Vita and HTC One X phones, two supported devices.
PlayStation Vita specifications
The following are the system requirements for PlayStation Vita:
HTC Hero One X specifications
The following are the system requirements for HTC Hero One X:
As you can see, PlayStation Mobile is running on some remarkably capable hardware. It’s hard to believe how far things have come when you consider the original PSP was running on a single CPU running at 333 MHz with only 32 MB RAM while the Gameboy DS was powered by a pair of CPUs running at 67 and 33.5 MHz, respectively, with a paltry 4 MB of RAM. This generation of handheld devices is sporting hardware comparable to what is found in the PlayStation 3 and Xbox 360!
What this book covers
Chapter 1, Getting Started, covers getting the PlayStation Mobile SDK up and running and deployed to various devices (a task of some complexity). It jumps right in, creating basic graphical applications and covers the details and restraints of working on the devices.
Chapter 2, Controlling Your PlayStation Mobile Device, covers all the various ways in which you can control PSM devices, from the traditional joystick to touch and motion controls. Additionally, since not all devices have the same capabilities, it covers creation and handling of on-screen controllers.
Chapter 3, Graphics with GameEngine 2D, covers the graphical aspects of working with GameEngine2D—a higher level 2D gaming engine similar in design to the popular Cocos2D. It covers all aspects of 2D graphics from scenes and sprites to special effects and performance optimizations with SpriteLists.
Chapter 4, Performing Actions with GameEngine 2D, covers the action side of using GameEngine2D. This involves updating game objects, scheduling events, and executing actions, both in-built actions such as MoveTo and MoveBy and also defining your own.
Chapter 5, Working with Physics2D, covers working with Physics2D, PSM SDK’s in-built 2D physics system for creating physics simulations. Physics2D is not the only option for physics, so it also looks at integrating the popular BEPU and FarSeer XNA physics engines into your PSM application.
Chapter 6, Working with GUIs, covers the UI system built into the PlayStation Mobile. This ranges from creating on-screen buttons and panels, handling clicks and hold events, to advanced touch gestures. Additionally, it covers using UIComposer to visually create and edit UIs.
Chapter 7, Into the Third Dimension, covers working in 3D, from creating a camera and using graphic primitives to using fragment and vertex shaders.
Chapter 8, Working with the Model Library, covers working with 3D objects, including creating and exporting them using a third party application, converting them using the SDK tools, and finally displaying and animating them in 3D.
Chapter 9, Finishing Touches covers the wealth of networking options available to PSM devices. Additionally, we cover the Publishing tool and preparing your application for deployment to the PlayStation Mobile App Store.
Appendix, Publishing Your Application, covers the process of compiling, signing, packaging, and deploying your finished application to the PlayStation App Store.
What you need for this book

Chapter 1. Getting Started
In this chapter we will cover:
Introduction
The PlayStation Mobile (PSM) SDK represents an exciting opportunity for game developers of all stripes, from hobbyists to indie and professional developers. It contains everything you need to quickly develop a game using the C# programming language. Perhaps more importantly, it provides a market for those games. If you are currently using XNA, you will feel right at home with the PSM SDK.
You may be wondering at this point, Why develop for PlayStation Mobile at all? Obviously, the easiest answer is, so you can develop for PlayStation Vita, which of itself will be enough for many people. Perhaps, though the most important reason is that it represents a group of dedicated gamers hungry for games. While there are a wealth of games available for Android, finding them on the App Store is a mess, while supporting the literally thousands of devices is a nightmare. With PlayStation Mobile, you have a common development environment, targeting powerful devices with a dedicated store catering to gamers.
We are now going to jump right in and get those tools up and running. Of course, we will also write some code and show how easy it is to get it running on your device. PlayStation Mobile allows you to target a number of different devices and we will cover the three major targets (the Simulator, PlayStation Vita, and Android). You do not need to have a device to follow along, although certain functionality will not be available on the Simulator.
One thing to keep in mind with the PlayStation Mobile SDK is that it is essentially two SDKs in one. There is a much lower level set of libraries for accessing graphics, audio, and input, as well as a higher-level layer build over the top of this layer, mostly with the complete source available. Of course, underneath this all there is the .NET framework. In this chapter, we are going to deal with the lower level graphics interface. If the code seems initially quite long or daunting for what seems like a simple task, don't worry! There is a much easier way that we will cover later in the book.
Accessing the PlayStation Mobile portal
This recipe looks at creating a PSM portal account. For this process it is mandatory to download and use the PSM SDK.
Getting ready
You need to have a Sony Entertainment Network (SEN) account to register with the PSM portal. This is the standard account you use to bring your PlayStation device online, so you may already have one. If not, create one at http://bit.ly/Yiglfk before continuing.
How to do it...
How it works...
A PlayStation Mobile account is mandatory to download the PSM tools. Many of the links to the portal require you to be logged in before they will work. It is very important that you create and activate your account and log in to the portal before continuing on with the book! All future recipes assume you are logged in to the portal.
Installing the PlayStation Mobile SDK
This recipe demonstrates how to install the PlayStation Mobile SDK.
Getting ready
First you need to download the PlayStation Mobile SDK; you can download it from http://bit.ly/W8rhhx.
How to do it...
How it works...
The SDK is now installed on your machines. Assuming you used default directories, the SDK will be installed to C:\Program Files (x86)\SCE\PSM if you are running 64 bit Windows, or to C:\Program Files\SCE\PSM if you are running 32 bit Windows. Additionally all of the documentation and samples have been installed under the Public account, located in C:\Users\Public\Documents\PSM.
There's more...
There are a number of samples available in the samples directory and you should certainly take a moment to check them out. They range in complexity from simple Hello World applications, up to a full blown 3rd person 3D role playing game (RPG). They are, however, often documented in Japanese and often rely on other samples, making learning from them a frustrating experience at times, at least, for those of us who do not understand Japanese!
