What's the easiest way to...

[Magentix]

play a 3D sound when I cast an ability?

I've checked the natives and BJs in JassCraft, but they weren't as self-explanatory as most other Natives/BJs.

Could anyone point me in the right direction please?

 

[Waaaaagh]

Err... I dunno. Usually, I don't check JassCraft for native and BJs. I do it in GUI, convert it, and see what it does, takes, blah blah. Then, if it's a BJ (it usually is), search JassCraft for the BJ, and look at the natives it calls. Then go from there.

function PlaySoundOnUnitBJ takes sound soundHandle, real volumePercent, unit whichUnit returns nothing
    call AttachSoundToUnitBJ(soundHandle, whichUnit)
    call SetSoundVolumeBJ(soundHandle, volumePercent)
    call PlaySoundBJ(soundHandle)
endfunction

function PlaySoundAtPointBJ takes sound soundHandle, real volumePercent, location loc, real z returns nothing
    call SetSoundPositionLocBJ(soundHandle, loc, z)
    call SetSoundVolumeBJ(soundHandle, volumePercent)
    call PlaySoundBJ(soundHandle)
endfunction

spell cast - play sound on trigger unit

What's the SoundHandle?

 

[0zaru]

 takes sound soundHandle

That's the soundHandle that is a sound
call Whatever(<YourSound>, bla bla bla)

IMO, you should just use PlaySoundBJ:

function PlaySoundBJ takes sound soundHandle returns nothing
    set bj_lastPlayedSound = soundHandle
    if (soundHandle != null) then
        call StartSound(soundHandle)
    endif
endfunction

The sound handle is the named of the sound.

EG: gg_snd_SOUNDNAME

The sounds have to be "used as sounds" from the Sound Editor.

Dont you have to 'killsoundwhendone' or whatever the native is?

Only kill it if you play it once, methinks.

Heres a quick custom function i'll write for you:

function SoundAtLoc takes sound s location l returns nothing
  call SetSoundPosition(s,GetLocationX(l),GetLocationY(l),0)
  call StartSound(s)
endfunction

There you go!

If you want me to create a local sound variable that is in itself distinguishable just ask. I'm pretty sure that one will run the fastest, though, unless it leaks.

To fill in the parameters for a unit casting a spell you would use SoundAtLoc(gg_snd_WhatSoundYouWant, GetUnitLoc(GetSpellAbilityUnit()) That would leak though so if you want to fix the leaks you would do:

local unit u = GetSpellAbilityUnit()
local location l = GetUnitLoc(u)
call SoundAtLoc(gg_snd_WhatSoundYouWant, l)
set u = null
call RemoveLocation(l)
set l = null

Yup, just put that in your functions in the trigger and my custom func in the custom script section (click your map name at the top in the trigger editor).
