PlayStation Mobile Development Cookbook

Chapter 2. Controlling Your PlayStation Mobile Device

In this chapter we will cover:

  • Handling the controller's d-pad and buttons

  • Using the Input2 wrapper class

  • Using the analog joysticks

  • Handling touch events

  • Using the motion sensors

  • Creating onscreen controls for devices without gamepads

  • Configuring an Android application to use onscreen controls

Introduction


In this chapter, we are going to look at the various ways you can control your PlayStation Mobile device. The PlayStation Vita includes touch sensors, a full d-pad, two analog sticks, motion sensors, and more. It has to stay compatible with other devices, so features such as the rear touch panel are not supported. Not all devices support all of the PS Vita's features; in fact, most do not. This is especially true regarding physical joystick support. Fortunately, Sony has provided a tool for making onscreen controls, which we will cover shortly. The onscreen controls are built directly into the PSM virtual machine; you simply configure the screen layout the way you wish to see it appear.

There are, however, some limitations, especially when it comes to what you can do in the simulator. For some of these recipes, you will require an actual physical device to test them. I will point out at the beginning of each recipe if there are special requirements.

You may also notice, examples...

Handling the controller's d-pad and buttons


In this recipe, we will look at how to read the device's gamepad's d-pad and button states. The code remains the same regardless of whether it is a physical device or if the controls are emulated.

Getting ready

Load up PlayStation Mobile Studio and create a new project. Add a reference to Sce.PlayStation.GameEngine2D and Sce.PlayStation.GameEngine2D.Base. The complete source for this example can be found in Ch2_Example1.

How to do it...

In the AppMain.cs file of your newly created project, enter the following code:

using System;
using System.Collections.Generic;

using Sce.PlayStation.Core;
using Sce.PlayStation.Core.Environment;
using Sce.PlayStation.Core.Graphics;
using Sce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.GameEngine2D;
using Sce.PlayStation.HighLevel.GameEngine2D.Base;

namespace Ch2_Example1
{
  public class AppMain
  {
    public static void Main (string[] args)
    {
      Director.Initialize();
      Scene scene = new...

Using the Input2 wrapper class


In the previous recipe, you may have found the bit masking process a little crude. Apparently so did Sony, as they provided a helper method in the GameEngine2D library named Input2 that makes dealing with input a bit smoother. In this recipe, we are going to demonstrate how that class works.

Getting ready

Open or duplicate the code you created in the previous recipe. Only the contents of the while loop are going to change in this recipe. The full code for this recipe is available at Ch2_Example2.

How to do it...

Open AppMain.cs and change the contents to the following code:

while(!quitApp)
      {
        Director.Instance.Update();
        string currentStatus = "Your DPad is current pointing at: x=";

        currentStatus += Input2.GamePad0.Dpad.X;
        currentStatus += " y=";
        currentStatus += Input2.GamePad0.Dpad.Y;
        label.Text = currentStatus;
        if(Input2.GamePad0.Cross.Press)
          quitApp = true;

        if(Input2.GamePad0.Circle...

Using the analog joysticks


In this recipe, we will demonstrate how to use the device's analog sticks, if they exist. If they do not exist, the onscreen controller will appear automatically.

Getting ready

In PSM Studio, create a new project and add a reference to Sce.PlayStation.GameEngine2D and Sce.PlayStation.GameEngine2D.Base. This recipe also requires you to add an image file to be displayed. I am bringing back our trusty F-18 graphic, but you can substitute whatever image you desire as long as it is in the proper format (.png, .bmp, or .jpg). The full code for this recipe is available at Ch2_Example3.

This example requires an actual device!

How to do it...

Open AppMain.cs and enter the following code:

using System;
using System.Collections.Generic;

using Sce.PlayStation.Core;
using Sce.PlayStation.Core.Environment;
using Sce.PlayStation.Core.Graphics;
using Sce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.GameEngine2D;
using Sce.PlayStation.HighLevel.GameEngine2D.Base;

namespace...

Handling touch events


In this recipe we will look into how to deal with touch events.

Getting ready

In PSM Studio, create a new project and add a reference to Sce.PlayStation.GameEngine2D and Sce.PlayStation.GameEngine2D.Base. Then add an image file to your project (I will re-use the trusty F18) and make sure its Build Action is set to Content. The full code for this recipe is available as Ch2_Example4.

This example will run in the simulator; however, it does not currently support multitouch. To see multiple touches handled, you will need to run this code on an actual device.

How to do it...

Open AppMain.cs and enter the following code:

using System;
using System.Collections.Generic;

using Sce.PlayStation.Core;
using Sce.PlayStation.Core.Environment;
using Sce.PlayStation.Core.Graphics;
using Sce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.GameEngine2D;
using Sce.PlayStation.HighLevel.GameEngine2D.Base;

namespace Ch2_Example4
{
  public class AppMain
  {
    public static void Main...

Using the motion sensors


In this recipe we will look into how to use the accelerometer and gyroscope.

Getting ready

Open PSM Studio and create a new project, adding references for GameEngine2D and GameEngine2D.Base. The complete code for this recipe is available at Ch2_Example5.

This example will not run in the simulator. Some Android based devices may not support the gyro, so AngularVelocity may not be available.

How to do it...

Open AppMain.cs and enter the following code:

using System;
using System.Collections.Generic;

using Sce.PlayStation.Core;
using Sce.PlayStation.Core.Environment;
using Sce.PlayStation.Core.Graphics;
using Sce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.GameEngine2D;
using Sce.PlayStation.HighLevel.GameEngine2D.Base;

namespace Ch2_Example5
{
  public class AppMain
  {
    public static void Main (string[] args)
    {
      Director.Initialize();
      Scene scene = new Scene();
      scene.Camera.SetViewFromViewport();

      float screenWidth = Director...

Creating onscreen controls for devices without gamepads


In this recipe, we will look at creating onscreen controls for devices that do not have physical controls. We are going to configure a control set that has a left hand analog stick, select, start, as well as the cross, and triangle buttons. We are going to layout controls for an example device, the Xperia Arc, which has a 4.2" 480 x 854 screen.

Getting ready

This recipe can be created on your computer, however you will require an Android device to test it, as onscreen controls cannot be run on the Vita or simulator.

To get started, locate and execute OscCustomizeTool.exe. It will be located in the Tools folder, under the PSM Studio install directory. On my machine, which was installed using defaults, this file was located at C:\Program Files (x86)\SCE\PSM\tools\OscCustomizeTool.

How to do it…

  1. On the main screen, uncheck all buttons except the L Analog, Select/Start, Select, Start, Face Button, Cross, and Triangle buttons like this:

  2. Switch...

Configuring an Android application to use onscreen controls


In this recipe, we will look at configuring onscreen controls on an Android device.

Getting ready

You need to have run through the prior recipe, or generated the osc.cfg file, which needs to be named exactly that. Locate the application PublishingUtility.exe. On my default install, it is located at C:\Program Files (x86)\SCE\PSM\tools\PublishingUtility. You will also need a PSM project you want to add the controls to.

How to do it…

  1. Load PublishingUtility.exe.

  2. Locate the Gamepad section and, in the drop-down to the right, set it to true.

  3. Click on the Save button and save the file as app.xml in the same file location as osc.cfg.

  4. In the project you want to add onscreen controls to, add app.xml, allowing it to overwrite the default.

  5. Also add the file osc.cfg, then right-click it in the Solution view and set its Build Action to Content.

You are now complete; when the project is run on an Android device the customized onscreen keyboard will be...

This book covers so much so well that I don't know where I would be without it when it comes to the Playstation Mobile SDK. It is an excellent starting point and reference. I would highly recommend this book - and with the SDK being so simple to use with the aid of this book and Sony Mobile Developer's licenses being so cheap it is definitely worth it!

I bought this book because I wanted to start developing for the PS Vita... and that's what it is all about. Some C# knowledge (or Java) would help you to start and this book will take you from that point to deploying your own apps/games on your PS Vita without wasting money (developers' tool and license are free right now!) or time. It doesn't get so heavy and practically covers everything on the PS (Controls, colors, sprites,...). On the other hand I think a second book would be helpful, or at least if you want to build your own best selling game!

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
