I downloaded a few B.A.T.s that when you plop them a third party sound plays that isn't originally in the game... such as the coca cola building... when plopped the "always coca cola" tune plays... what do i need to do to use custom plop sounds in my B.A.T.s I have a few .wav files i want to use as a plop sound
There's only one, very old, tutorial available about custom sounds; this one by Pegasus (http://www.simtropolis.com/forum/messageview.cfm?catid=42&threadid=49433).
Those two TRK files that Pegasus is referring to have long ago disappeared from that thread.
I'm attaching that original file to this post for you though. ;)
Once you've created your own TRK file, link to its unique IID from the property SFX:Default Plop Sound in the building exemplar.
