P3D v2 Sound with attachpoint not working?

[mskhan1991]

I attached a sound with my frigate for my upcoming alouette project.

The problem is I can't hear the sound ... here's my code:

[Library Effect]
Lifetime=5
Version=2.00
Display Name=type21 sound
Radius=200
Priority=0
[Sound]
Looping=TRUE
MinAttenuationDistance=300
FileName=MSK T-21 sound.wav

Hi.

I think the sim might not like spaces in the filename

FileName=MSK T-21 sound.wav

it was one of the problems... but still no sound!

 

[mskhan1991]

All I want to do is attach sound to a simobject using attachpt tool..... a sound that runs 24/7 and loops .... and want to hear it around 300-500 meters from the origin.....

My current complete code.... is it correct?

[Library Effect]

Lifetime=5
Version=2.00
Radius=300
Priority=0
   
[Sound]
FileName=MSK_T-21_sound
MinAttenuationDistance=500.00
Looping=TRUE

[Properties]
Spot=1
Tower=1

Hello:

I'm not sure yet whether Lockheed-Martin has changed how the SDK works with the Special Effects coding for sound, particularly when implemented via an AttachPoint on the revised P3D *.MDL format.

If by any chance it still works as it did for FSX, you might wish to review this thread for some example code structures and related info:

http://www.fsdeveloper.com/forum/threads/sound-effects.424400/


IIRC, in examples posted thus far, one normally does not also specify the *.WAV file "extension" for the sound file "name" ...unless one is listing an explicit path to a sound file physically located outside the FSX default 'system' sub-folder for sounds at:

[FSX install path]\Sound


And of course, if you do intend to play a sound file without listing an "explicit path" to a sound file physically located outside the FSX default 'system' sub-folder, a copy of the desired sound file must be placed into [FSX install path]\Sound ...in order for the FSX Effect engine to "find" and "play" it.


Hope this helps !

Thanks.

I don't know why but I added emitter.0 section from fx_explosion.fx and changed the lifetime to 99999 and its working now .. hmmm

Indeed, FS Effect (*.Fx) code <...for FSX, at least > appears to require an 'emitter', as these "minimum-size" worked example files show:

Feel free to copy and modify that code as you wish for your own projects.


Hope this helps your conditional triggers work properly for P3D !

Thanks.... but if instead of changing lifetime=9999 to lifetime=0.00 .... will it work throughout?

Hello again:

I'm unfamiliar with use of "9999" as a parameter value in *.Fx files for anything related to "sound" (only seen used for Drag and/or Temperature).

I'd recommend testing using the commonly seen values of "x.xx", rather than "9999" as shown in the worked examples linked above.


FYI: FSX constantly loads and then promptly unloads *.WAV files from the Windows FS task session UserVAS when a sound-playing Effect is triggered and played.

Such recurrent file I/O is particularly adverse to performance in FSX, so IMHO, one would wish to trigger the Effect to begin playing the sound only when the user aircraft / SimObject / camera is inside the trigger radius.


The Effect *.Fx code should also be written so that the sound attenuates and eventually stops entirely after the user aircraft / SimObject / camera is outside the trigger radius.


PS: You may wish to review some of the other detailed info and linked example files involving use of FS Effects to play sounds in this thread:

Note: In the thread linked immediately above, see especially the linked early FSX add-on package of freeware examples created by Joe Watson for Plum Island (ICAO 2B2) which works with both Bill Womack's excellent payware airport and area scenery package published by FS-Addon, as well as the FSX default airport.

Hope this helps a bit more !
