its kinda complicated, now that i think about it. there's no string to sound trigger so you'll have to make dew with this
open the mpq archive in wc3 called "War3.mpq" and then take a sound that your not using <in this case probably music> and copy its filepath
I'm going to use "Doom.mp3" for mine
The path is "Sound\Music\mp3music\Doom.mp3"
And make a folder for each of the \'s in your own mpq
Name the file the same that your going to replace
And now go to Sound manager = Select Music\Internal\Doom.mp3 <its the Doom.mp3 that counts>
And click ---<Use As Music>---
Now go to Trigger Editor
Create new trigger
it should look like this when your done
-
Untitled Trigger 001

This should work, i dont really have the time to make a new mpq, but tell me if it doesn't work, if it doesn't i've wasted alot of time, and its impossible
