Cohort Unity Client

This Unity project includes the Cohort Unity Client asset package and is useful as a template or for testing Cohort. If you have an existing Unity project, you can download and install the asset package linked above, and import it into your project.

Using the example Unity project

  • clone or download this repo and open it in Unity
  • open up CohortUnityClient/Scenes/CohortDemoScene and have a look at the CohortManager GameObject
  • it connects to a Cohort server (online or local), keeps track of sound and video cues, and triggers them in response to Cohort messages received over the network

Getting started with the Cohort Unity Client

  • download the Cohort Unity Client asset package and import it into your Unity project

Import (paid) dependencies from Unity Asset Store

Setting up cues

  • create a plain GameObject and name it 'CohortManager'
  • drag CohortUnityClient/Scripts/CHSession.cs onto the CohortManager GameObject
  • for sound cues:
    • create an Audio Source GameObject
    • select the CohortManager GameObject
      • in the Inspector, under 'CH Session', set the 'Audio Player' field to your Audio Source
    • import your sound files to /Resources (as Audio Clips)
      • you can set desired transcode / quality settings under your Audio Clips' Import Settings
    • select the CohortManager GameObject
    • under CH Session > Sound Cues, set Size to 1
    • under Element 0:
      • set the Audio Clip field to one of your Audio Clips
      • set Cue Number to 1 (point cue numbers like 10.5 are fine too)
      • if the cue has speech: transcribe it in the 'Accessible Alternative' field
      • if the cue is music or sound effects: provide a description in the 'Accessible Alternative' field
    • for additional cues, increment the Sound Cues > Size field and set the details (Audio Clip, Cue Number, Accessible Alternative) for each new cue
  • video cues follow a similar flow:
    • create a Video Player GameObject
    • link it to the CH Session using the Video Player field
    • import your video clips
    • add a Video Cue for each clip

Testing locally

  • start an instance of Cohort Server running locally
    • for this test, make sure you have run the default DB seeds (THIS STEP IS INADEQUATELY DOCUMENTED)

Back in Unity...

  • under CH Session, enter the following values:
Field Value
Server URL localhost
Http Port 3000
Web Socket Path /sockets
Event Id [your event ID, or 4 for testing]
Client Occasion [your occasion ID, or 1 for testing]
Client Tag any
  • enter Play mode
  • you should see console messages saying "req 1 complete", "req 1.5 complete", and "req 2 complete", as well as "opened websocket connection"

Triggering cue playback

  • use a tool like Postman to send the following JSON as a POST request to 'http://localhost:3000/api/v1/events/4/broadcast' (set the Content-Type header to application/json):
      "mediaDomain": 0,
      "cueNumber": 1,
      "cueAction": 0,
      "targetTags": ["all"]
  • a 'meow' sound should play
  • for video cues, set 'mediaDomain' to 1
  • check the Cohort Spec for detailed info on these messages

Testing on a device

  • select the CohortManager GameObject
    • in the Inspector, under CH Session > Server URL, replace 'localhost' with your IP address or computer name (i.e. 'jakemoves.local')
  • build your Unity project and run it on a device from Xcode
You can’t perform that action at this time.
