Hi! We’re using Fmod 2.01.11 at the moment (paired with Unity). In your documentation, it says “An event is considered oneshot if it is guaranteed to terminate without intervention in bounded time after being started.” And yet we’ve encountered a few confusing examples of this not holding true. F…

I believe the criteria for how a oneshot event is determined hasn’t been looked into for a while and it’s possible that some features might not properly fit into what an expected oneshot event should be. I’ve raised this as an issue to look into by our development team for a future version of FMOD S…

Thanks for the brisk response. Sadly that’s not it. Persistence stays greyed out. [oneshot false event 01] [oneshot false event 02] [oneshot false event 03] [oneshot false event 04]

It’s a bit hard to briefly define a one-shot event, but essentially it means an event you can press play on and it will naturally stop by itself. There are certain objects within an event that will trigger the isOneShot flag. Objects such as: Looping instruments on parameter sheets or action sheet…

For the snapshot event, I guess a workaround would be to start and stop the snapshot by using command instruments. [image] richard_simms: The reason a snapshot instrument causes it to become non-oneshot is because a snapshot itself is not oneshot (it has no natural end). But if the parent ev…

@Alcibiade is correct. It’s a single instrument, lasting 0.5 seconds on a timeline, its “loop instrument” checkbox is checked. After approx. 0.5 seconds cursor untriggers this instrument and the event as a whole stops on its own.

Got it. Thank you, guys! We will look into this as a temporary solution. :+1:

I don’t use Unity at the moment so I’m not aware of how the oneshot status appears. However, I did found in FMOD Studio a behavior that seems to be related to that oneshot status, though not documented anywhere: how untriggered nested events react (with “cut” unchecked). If it’s oneshot, it continue…

Hello, We’re in a similar situation. We moved from 2.01.09 to 2.01.11 and a bunch of behaviour that relied upon the One Shot status of an event broke. Have there been any updates on this? If I understand correctly, it appears the definition of a one shot changed in 2.01.11. (Maybe in order to imp…

Revising the conditions for if an event description returns it as a one shot will require a bit more time to take into consideration everything new added since the last time it was visited. I can’t say for certain, but it could be possible that since snapshots themselves operate like a persistent ev…

I would just add scatterer instruments to this list. They also have no defined end and will remove oneshot status.

Perhaps you checked “persistent: on” by mistake on both events?
