How to handle sound on same channel?

[Outcast]

I like to put every sound effect on a different channel so I can have better control of its volume. I do get problems however when there is a sound playing rapidly on one channel, for example a thud when an object collide with something, I may have that to play on channel 5, but if 3 of the objects collide close to each other the sound will cut 2 times before it plays fully the 3:rd time. Any suggestion on how to handle this?

Hello outcast! You could probably use an event that decides which channel to play the sound on by math instead of selecting it yourself!

What you need is:
an alterable value, any will do, even a global value.
A certain span of channels you're willing to devote to this, for example 6,7,8,9,10
An event that says like this:

On event
Play sample on a specific channel

and then you set the channel to Alterable Value A("Object") where "Object" is the active that holds the alterable value.
The Alterable value will have an initial value of 6 if you're going with the span I proposed earlier. After that you need to increase the value of the alterable value by one, this could perhaps be done in the same event, I'm not sure.
Finally, you will need an event that checks to see if the alterable value is 10 or higher, in which case the alterable value will be set to 6.

Sorry if it all comes out a bit rambly! If you wonder about anything, don't hesitate to ask!

Tested this myself now, and it works
The drawback is that it takes up quite a few channels, I don't know exactly how many you'd need to get a smooth playback.

Nice I will try this out! Maybe I will just go for 3 channels though, I already have 20 occupied so its only 12 left : p. About setting it back to 6, can this be done with the "mod" function? I have not really grasped how mod works fully, but I believe it is used for stuff like this?

Mod might work ^^ I'm such a math-newb that it didn't occur to me, however since you aren't increasing the alterable value when you call upon it in the sound event, you'd still need an event that changes the alterable value so the next time the sound is called upon, it will be one value higher. If you could somehow alter the variable in the same line where you are calling upon it, and you could implement the mod function, it would be a bit shorter and more neat!

You cannot have two sounds on the same channel; the purpose of channels is to allow playing multiple sounds at once.

LB is right, that's the whole purpose of being able to utilise individual channels. I tried a few methods like this for my Android development. If the sample is being played numerous times, by default MMF2 will scan and play the sample in an open channel...

I think I have got it to work well now! I am also using one long sample with about 10 different sound effects and setting the sounds position at random on each hit so it sounds a bit dynamic. I don't know if this is a better method though then to actually split it up in 10 different sound files and pick one at random? (apart from having less files :p )
