Overview of this book

With the PlayStation¬ÆMobile SDK you can create stunning games for the PlayStation¬ÆVita and PlayStation‚Ñ¢Certified devices (PS Certified devices). It includes everything you need to get started, including an IDE for developing your code and even an emulator to test your creations. "PlayStation¬ÆMobile Development Cookbook"| is an exciting and practical collection of recipes that help you make the most of this exciting new platform. It provides you with everything you need to create complete 2D or 3D games and applications that fully unlock the potential of the SDK. After quickly covering the basics, you'll learn how to utilize input sources like touch, gamepads, and motion controls, and then move on to more advanced content like creating and animating 2D graphics, networking, playing sound effects and music, adding physics, and then finally jumping into the world of 3D.

Creating a (physics!) joint

In this recipe, we are going to look at simulating a joint to create a pendulum style effect, swinging one physics body around another.

Getting ready

Load up PlayStation Mobile Studio and create a new project. Add a reference to Sce.PlayStation.HighLevel.GameEngine2D and Sce.PlayStation.HighLevel.Physics2D. We will be re-using our earth sprite from the earlier recipe, this time reduced in size by 50 percent and named, appropriately enough, earthSmall.png. Add this image or a similar one to your scene and set its Build Type to Content. The complete source and all images used can be found in Ch5_Example3.

How to do it...

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

using System;
usingSce.PlayStation.Core;
usingSce.PlayStation.Core.Graphics;
usingSce.PlayStation.Core.Input;
using Sce.PlayStation.HighLevel.GameEngine2D;
using Sce.PlayStation.HighLevel.GameEngine2D.Base;
