Safely check whether an event exists to avoid crashes in live build

Unity

I’ve been searching for a solution on this but have been unable to find any way to do it. Hoping I’ve just missed something obvious.

We have a lot of sounds in the game, and some categories of SFX are set up and assigned via our external sheets. We have a pretty safe database generator so no manual strings are being entered anywhere for FMOD events, but things can still slip through the cracks from time to time (it’s happened a few times already, and we’re still in alpha).

My expectation was that the API would let me do something like
if(!CheckEventExists("some event")) return;
So that as an absolute worst case, a mistake in event path/bank contents would result in silence, not an app crash when CreateInstance() is called on a bad string.

Can’t seem to find anything like that, so I’m hoping others that may be in a similar situation (or have been) might be able to shed light on best practices. Would just like to reduce FMOD’s/game-sound’s chances of crashing (via human error on content) the app to 0%.

ok… typically, some continue digging after posting this turned up what I needed.

In case it helps anyone else:
RuntimeManager.StudioSystem.getEvent(id, out desc);

then check .isValid() on out desc object.

If, like in our project, you’re building event paths or managing them externally in your pipeline (e.g. vast spreadsheets of player-equipment), you can make sure your CreateInstance() calls won’t throw an exception from content mistakes.

You could also check if getEvent returns FMOD.RESULT.OK. If the Event doesn’t exists for some reason it should return ERR_EVENT_NOTFOUND.
