Bolt OSC Jack

Bolt OSC Jack is an add-on for Unity's Bolt visual scripting system that adds custom units for handling OSC (Open Sound Control) messages.

It uses OSC Jack as a backend. If you're interested in using OSC without visual scripting, check the OSC Jack project.

Custom Units

OSC Input unit

OSC Input is a unit for receiving OSC messages in a flow graph. You can specify a UDP port number and an OSC address to which the unit listens.

There are variants for different data types:

• OscBangInput (trigger without data)
• OscIntInput
• OscFloatInput
• OscStringInput
• OscVector2Input
• OscVector3Input
• OscVector4Input

Note that it could trigger the event multiple times in a single frame.

OSC Output unit

OSC Output is a unit for sending OSC messages from a flow graph. You can specify a destination IP address, a UDP port number, and an OSC address to which the unit delivers messages.

There are variants for different data types:

• OscBangOutput (trigger without data)
• OscIntOutput
• OscFloatOutput
• OscStringOutput
• OscVector2Output
• OscVector3Output
• OscVector4Output

How to try the sample project

This repository doesn't contain the Bolt assets due to the license restriction. You have to import Bolt via Asset Store manually.

You can't use the "Install Bolt" tool due to compilation errors caused by missing file references. You have to manually double-click the Bolt_1_4_X_NET4.unitypackage file in the "Install Bolt" directory instead.

After importing the unitypackage file, it automatically opens the Bolt Setup Wizard.

On the Assembly Options page, add Bolt.Addons.OscJack.Runtime to the assembly list.
