Triggers:USING IMPORTED SOUNDS AS BACKGROUND MUSIC

[Leutian]

ok how do you use an imported, MP3 or .wav file as bg music on a custom map? i been looking everywhere for this info and havent found much info on sound triggers or anything else like that for that matter?

 

[Darg]

uh, have you tried playing around with the "sound - set music list" action?

TRiggers:changing the BG sound

yeah actually i figured out how to make it play one song and then tried playin around with the sound list command but the music list command wont work without more than one song i was just tryin to get it to play one song and have it loop thru the entire mission.

 

[Darg]

oops, I just remembered I should already know how to do this:

Here's how to make a music list of imported music, this will also work if you just wanna play the one sound looped.

In Sound Editor, Import External Music will import individual mp3
songs. In order to create a music list of them, you have to use
Custom Text.

1. In Trigger Editor, create a new trigger with no events or
conditions, and a single action:
Music - Play Music

2. Select Edit|Convert to Custom Text, ignoring the warning
dialog. In the custom text, you will see a function that looks
like:
function Trig_Create_Music_List_Actions takes nothing returns
nothing
call PlayMusicBJ(" .....

3. Alter that function to indicate the mp3 files that you have
imported. You must not use their variable names, but their file
names, and you must include the path shown below.

function Trig_Create_Music_List_Actions takes nothing returns
nothing
call PlayMusicBJ(
"war3mapImported\\Handel.mp3;war3mapImported\\Bach.mp3;war3mapI
m
ported\\Mozart.mp3" )
endfunction

the line that begins with "call" should all be on one line

until the closing parenthesis. In the above examples, I am
creating a play list of three imported mp3 files: Handel.mp3,
Bach.mp3, and Mozart.mp3. You must include the
"war3mapImported\\" path for each file.

4. When this trigger is run, it will begin to play the new music
list, starting with a random song, and then cycle through them
repeatedly.

If you make any action to play the default 'music' preset, then
you must call this trigger again to return to your custom play
list.

If you are uncomfortable with custom text, don't worry too much,
since you can always delete the trigger and start over. The
conversion to custom text will only affect the selected trigger.

Keep in mind that imported songs are quite large, and that the
total size of all the imported files will be added to the storage
size of the saved game. Battle.net limits maps to 4MB.

hey cool man sorry took so long to reply but i got it working

 

[Darg]

good to know

Darg: i did exactly what you said, but it won't loop the tracks. it just plays one song and then stops. here's the code for my trigger:

function Trig_Set_Soundtrack_Actions takes nothing returns nothing
call SetMapMusicRandomBJ( "war3mapImported\\Dirt Off Your Shoulder-Lying From You.mp3;war3mapImported\\Big Pimpin'-Papercut.mp3;war3mapImported\\Jigga What-Faint.mp3;war3mapImported\\Numb-Encore.mp3;war3mapImported\\Izzo-In The End.mp3;war3mapImported\\Points of Authority-99 Problems-One Step Closer.mp3" )
call TriggerExecute( gg_trg_Loop_Soundtrack )
endfunction

//===========================================================================
function InitTrig_Set_Soundtrack takes nothing returns nothing
set gg_trg_Set_Soundtrack = CreateTrigger( )
call TriggerAddAction( gg_trg_Set_Soundtrack, function Trig_Set_Soundtrack_Actions )
endfunction

 

[Darg]

well no you haven't, because I wrote the name of the play music function as "PlayMusicBJ", and for some reason you are using a function called "SetMapMusicRandomBJ". That might be your problem.

 

[Agent2594]

ok...well, I changed the custom text so it now says:

function Trig_Set_Soundtrack_Actions takes nothing returns nothing
call PlayMusicBJ( "war3mapImported\\Dirt Off Your Shoulder-Lying From You.mp3;war3mapImported\\Big Pimpin'-Papercut.mp3;war3mapImported\\Jigga What-Faint.mp3;war3mapImported\\Numb-Encore.mp3;war3mapImported\\Izzo-In The End.mp3;war3mapImported\\Points of Authority-99 Problems-One Step Closer.mp3;" )
endfunction

//===========================================================================
function InitTrig_Set_Soundtrack takes nothing returns nothing
set gg_trg_Set_Soundtrack = CreateTrigger( )
call TriggerAddAction( gg_trg_Set_Soundtrack, function Trig_Set_Soundtrack_Actions )
endfunction

...and it STILL won't loop.

 

[Darg]

well it works for me, there are a couple of peculiarities though:

1) the playlist seems to always start with the SECOND listed song and not the first.

2) there is about a 10-15 second wait between one song ending and another song beginning.

it DEFINITELY loops though, I just tested it myself, see attached map.

 

[Agent2594]

OK...here's what I did.

I loaded your map into the Editor and test ran it. Worked fine. Then, I loaded my map and test ran it. Played one song, then stopped. So I took your trigger code and pasted it into my map and test ran that. It worked.

So now that I know that my code isn't messing it up, is there some sort of restriction on the type or size of MP3s I can import into my map?

 

[Agent2594]

Well...after a lot of thinking and playing around with trigger actions, I came up with this trigger. It works good enough for me, and it doesn't involve custom text (which isn't much of a hassle for me anyway, but whatever.)

This trigger is called by another trigger in my map, so it has no events or conditions.

ACTIONS

Set TrackNumber = Random integer number between 1 and 6
[If / Then / Else, Multiple Functions]
If - Conditions
(LastTrackNumber Equal to TrackNumber)
Then - Actions
Do nothing
Else - Actions
If (TrackNumber Equal to 1) then do (Sound - Play Track001 <gen>) else do (Do nothing)
If (TrackNumber Equal to 2) then do (Sound - Play Track002 <gen>) else do (Do nothing)
If (TrackNumber Equal to 3) then do (Sound - Play Track003 <gen>) else do (Do nothing)
If (TrackNumber Equal to 4) then do (Sound - Play Track004 <gen>) else do (Do nothing)
If (TrackNumber Equal to 5) then do (Sound - Play Track005 <gen>) else do (Do nothing)
If (TrackNumber Equal to 6) then do (Sound - Play Track006 <gen>) else do (Do nothing)
Wait ((Length of (Last played music)) + 1.00) seconds
[END If / Then / Else, Multiple Functions]
Set LastTrackNumber = TrackNumber
Trigger - Run (this trigger) (ignoring conditions)

I've tested this trigger several times, and it seems to work flawlessly. If anybody else feels like testing it, go ahead and let me know if you find any bugs.

EDIT: I already found a bug. I edited the code already so anybody who wants to can re-test it.

EDIT 2: Yet another bug! OK, people, try it again.
