Unity - iOS (openFrameworks) via OSC

This is an example project demonstrating bi-directional communication between a Unity application to a iOS application (built with openFrameworks) using the OSC (Open Sound Control) network protocol.

The project enables the user to manipulate the position of two game objects (Sphere in Unity (green), Circle in openFrameworks (red)). The updated position of the game object in Unity is sent via OSC to the iOS openFrameworks application and vice versa.

ofxOsc was used to send and receive OSC messages in openFrameworks. UnityOSC by Jorge Garcia was used in Unity to send OSC messages, while VVVUnityOSC by frankiezafe was used to specifically receive OSC messages, which originated from an openFrameworks client (feat. bundle management), in Unity.

Dependencies

This example has been built using the following specifications:

• OS X 10.11.4
• Xcode 7.3
• openFrameworks 0.9.3 (iOS release)
• ofxOsc
• Unity 5.3.1f1 Personal
• UnityOSC v.1.2 by Jorge Garcia
• VVVUnityOSC by frankiezafe
• OSC (Open Sound Control)

Note: Generally, the openFrameworks and Unity source code should work also within their Windows counterparts. Please check out the above stated dependencies for troubleshooting.

Architecture

Setup instructions

openFrameworks

1. Place the contents of the ios_of folder into your of_v0.9.3_ios_release/apps/myApps/ folder, or alternatively link the openFrameworks library accordingly within the iOS project settings. (Xcode only)
2. Check the Bundle Identifier and Team properties in the iOS project settings. (Xcode only)
3. In src/ofApp.h, change the OSC_OUT_HOST IP address to be the IP address of the machine you run the Unity application on.
4. In the src/ofApp.h, change the OSC_OUT_PORT and OSC_INC_PORT in case you want to use different ports. (optional)

Unity

1. Load the Default.unity scene located in the Assets/_Scenes folder.
2. In Assets/ThirdParty/OSC/OSCHandler.cs, change the CLIENT_IP_ADDRESS IP address to be the IP address of the device you run the openFrameworks application on.
3. In Assets/ThirdParty/OSC/OSCHandler.cs, change the CLIENT_PORT in case you want to use a different port for outgoing OSC messages. (optional)
4. In Assets/_Scripts/OSCConnector.cs, change the OSC_PORT in case you want to use a different port for incoming OSC messages. (optional)

Running the applications

1. Start the openFrameworks application.
2. Once 1. is running, start the Unity application.
3. Touch input on iOS moves the red circle/sphere. Selecting the Unity-Player-Controller in the Unity editor's SceneView and manipulating its position will move and update the green sphere/circle.
