.NET & Unity - Getting Started I (Hello World)

Contents

Introduction

In this tutorial you will prepare your development environment for using the .NET bindings for Gestureworks Core. The steps performed in this tutorial will prepare your environment for subsequent Gestureworks Core Unity tutorials. For this tutorial you will need the Gestureworks Core multitouch framework; a free trial is available.

Download the code for all of the C# & Unity multitouch tutorials here: gestureworks-unity on GitHub

GestureWorks Core “Bindings”

The various bindings included with GestureWorks Core allow a developer to create multitouch applications using their preferred language and framework, and are essentially mini-APIs providing an interface to the functions exported by the native GestureWorksCore library (GestureWorksCore32.dll). Source code for each of the bindings is included so that you may extend or modify them as you like, as well as providing a blueprint for creating bindings for other languages or frameworks.

GestureWorksCoreNET and Unity

The .NET bindings for GestureWorks Core can be used by any .NET project. The source code for the .NET bindings is provided for portability and extensibility, but can be used quite effectively as-is in most situations.

In this and the following tutorials, Unity is used for demonstrating GestureWorks Core fundamentals using the .NET bindings. Unity is a powerful 3D game engine that we think you will enjoy using in combination with GestureWorks.


Requirements

Estimated time to complete: 15 minutes

A number of software packages are required for completing this and the following .NET tutorials:

  • GestureWorks Core license
  • Microsoft Windows 7 or 8
  • Unity Pro 4
  • Microsoft Visual Studio (C# 2012 Express or Professional)
  • .NET 3.5 framework
  • Multitouch display device

Process Overview

  1. Download and install software prerequisites
  2. Download and install GestureWorks Core package
  3. Create a new project in Unity
  4. Add Gestureworks bindings to Assets directory
  5. Build settings
  6. Review and complete

Process Detail

1. Download and install software prerequisites

2. Download and install GestureWorks Core package

The GestureWorks Core installer package -- GestureWorksCoreSetup.exe -- contains the main GestureWorksCore.dll files (the "native" DLLs), various bindings (C++ .NET, Python, etc.), and supporting documentation. GestureWorksCore must be licensed prior to use in any software project.

  1. Download the GestureWorks Core Trial package from here.
  2. Double-click the downloaded installer package GestureWorksCoreSetup.exe to install GestureWorks Core. GestureWorks Core consists of the GestureWorksCore DLLs as well as various tutorials, bindings, and documentation.

3. Create a new project in Unity

To get started, open Unity and create a new project in the File > New Project menu

We will call our project in the next lesson Hello Multitouch, so please enter that name in a location that is most convenient. There are no extra package imports to check in the project creation wizard so after naming the project, press Create.

4. Add Gestureworks binding to the plugin directory

New folders and files are automatically created by Unity when creating a new project. The default folder structure in the root HelloMultitouch directory is as follows:

 \Assets
 \Library
 \ProjectSettings
 \Temp

The Assets folder is the location where you will be putting all your project specific items. Use the file explorer to create the following nested folder path inside Assets:

 Assets\Gestureworks\Core

Inside the Core directory, place GestureworksCore32.dll. Then copy the .NET binding called GestureWorksCoreNET32.dll inside the same directory. Your Core folder should have the following inside:

 GestureworksCore32.dll
 GestureWorksCoreNET32.dll

Go back to Unity and see if the GestureWorks folder appears in the project view window. If you successfully placed everything correctly, your Hello Multitouch project window in Unity should look like the screenshot below:

5. Build Settings

Save your scene to the main assets directory and give it the name MyScene. Then set your build settings by going to File > Build settings. Specify the build as Windows x86. Also add the current scene. Your build settings should look like the ones below.
