Ok, having an issue here. I have a fast firing weapon, but it is not that fast. I have it set up currently so it is playing a loop of fast firing sounds. Then on “not playing” i go to a tail sound. Works perfectly. If i single tap, the weapon only fires one projectile (i’m talking graphics here -…

Same problem. With a 120ms short sample and spawn rate set to 100%, poly set to 6, everything is fine. I go to 110% and everything gets choppy and stuttery. Doesnt matter how high I set the poly actually

Turns out the scatter problem is an fmod problem. It is solved in 2.01.09

Instead of scatterer you can just use a timeline loop (or a transition to marker with a condition) with an Async Multi-Sound to retrigger the shot in a loop. The Multi-Sound can also be given a poly limit with Steal Oldest. Even with limit of 2-3 voices it should have enough overlap to not sound cho…

It seems he wants a variable rate of fire (he has a parameter), that’s why the scatterer seemed a good solution. A simple loop won’t be able to achieve that. Interesting points, concerning image synchronization with fast firing weapons.

Variable rate can also be achieved on the timeline. If you raise the event master pitch (from the event macros), the timeline runs faster. If you then pitch down the multi-sounds in the timeline by the same amount (ie, you have a linear pitch-up envelope in master pitch, and a linear pitch-down enve…

Another thread on variable / dynamic fire rate: [image] Dynamic firerate for weapon FMOD Studio Hey Guys, i am trying to make a gunshot loop with a variable as firerate. So i want to jump to the start of the loop sooner, when the firerate ist higher. But i dont see how th…

Ok, still having problems. I updated FMOD and the scatterer instrument works now. If I create a sustain point and press “KeyOff”, everything stops as intended. The problem is how to implement this in game. What code should you write to call the key off? Currently we are doing this: EventInstance.…

I don’t know how to correctly implement the keyoff in Unity or with the API. However, there’s a nice workaround: condition the trigger point to “event stopped” (I will assume you have a recent enough FMOD version). That way, you’ll only need to stop the event to have the sustain point triggered.

Ah, like this? [image] If I make the event stat “Stopping”, then it doesn scatter correctly. It only plays the sound once and does not scatter. But the above picture setting, seems to work, at least in fmod. Will have to ask programmer to revert to stopping the old way before i can test Thanks m…

Yes, “not stopping”, that’s what I meant :slight_smile:
