Hey everyone!
I was looking through the manual, but couldn’t find my answer there specifically, so figured I’d ask here:
I’m trying to set up a super simple adaptive music demo for pitches and generally showcasing adaptive music at lectures. Very simple, just a Unity project with a play button, and a couple of buttons for parameter/intensity changes that trigger transitions.
When I build to Mac/Windows, the app works flawlessly, but when building and testing in WebGL, I get zero response from the state/parameter changes. The play button works, but nothing else. When I change the build settings to WebGL, it still works great in Unity, but the problems arise when testing the build locally in the browser.
Is there anything I can do about this, or is this the limitation of WebGL today?
Hi,
The issue is WebGL is single-threaded so it cannot load banks in the same manner you would use on other platforms.
We have an example script to asynchronously load banks and then trigger a scene load which can then play events: FMOD Studio | Scripting Examples - Asynchronous Loading.
We also have a full Unity HTML5 demo on our GitHub: GitHub - fmod/unity-html5-demo: Demonstration of the correct way to load banks for HTML5 within Unity using the FMOD For Unity integration. this displays using a loading scene with the script.
Hope this helps!
Hi Connor! Thank you! I just checked out the demo project, and that one works nicely. Thanks for sending that!
The project has no instances of “StudioParameterTrigger” I’m trying to get working in WebGL - just moving the playhead from one clip to the next in Fmod 
Is this possible in WebGL?
Yes, it is possible.
There are two options, setting the parameter on the emitter or using a FMOD Studio Parameter Trigger:
Unity Integration | Game Components - Studio Event Emitter
Unity Integration | Game Components - Studio Parameter Trigger
Hope this helps!
