Thank you for your kindness, Peter.

Well…I thought built-in rolloff models(Logarithmic & Linear) already have 3D parameters internally (distance, listener angle & event angle)
which are need to be updated by programmer.

To summarize:

1. Both ways’re exactly same when we use ‘built-in’ rolloff model(Log. & Lin.).
2. We must call EventSystem::set3DListenerAttributes when using ‘Custom’ 3D rolloff model with ‘Add 3D distance parameter’ for automatic-distance-update.

Any Correction?
Thanks.

In this specific case it doesn’t make a difference because the only event used in that example is 3DSoundEmit which does not have and distance parameters.

Hi Peter. Thank you for your explanation.

If only EventSystem::set3DListenerAttributes tell EventSystem to update distance parameters, then is that more suitable to use set3DListenerAttributes from EventSystem, not from System? (in main.cpp of 3DDEMO)

or

Did you mean, System::set3DListenerAttributes let System knows ?

Thanks.

Hey guys, there is one slight difference between the two. Calling EventSystem::set3DListenerAttributes will let the EventSystem know it needs to update distance parameters, other than that they are the same.

Our attention has been focussed on developing FMOD Studio, so we haven’t had the time to give proper attention to the forums.

Yes. I guess they’re same but I couldn’t be sure.
Anyway, thanks !!! martin 😀

May I know what made them ‘absent’ ?

In the absence of some firelight guys… I think these just refer to the same settings. The EventSystem version is just there to save you from having to dig in to get the System object in order to do this stuff.

Yeah! Good to know that!
Maybe many people are waiting for updates of docs & examples…including me 😀

Thanks.

Yep, that’s exactly right. In general there is no harm in using EventSystem version so it’s probably better practice to do it that way regardless. I’ll make a note of it and hopefully we’ll get around to looking into updating the examples soon.
