Adding sounds should work, I added some extra sounds (just a few) to my own mod. (the sheep and wolf sounds). Did you put the sounds in the correct directory of your module?
Hmm, the sound works fine when I add it as a monster sound like in your mod. but it just won't work with items? Well, I still don't understand how it can still play the original sound when there's no mention of it anymore...
Hmm.. there seem to be two files related to items that both refer to sound files, probably one of them overrides the other one... which one did you change?
There's Main_ItemClasses.txt in the DO\modules\modulename\tiles folder, and Classes_ItemClasses.txt in the DO\Data folder.
Weird, but there might be another less elegant way. You could copy the wrench sound inside the "sounds" directory of your own module and rename it to whatever the healtpotion sound is in the standard Version. The game should check for the soundfile in the mod folder before it checks the base folder.
Great! It works now, Thanks a lot!
Weird thing is, the fuel sound still won't work, even though it never used a different sound (I gave it the drink.wav, not correct, but it was a start ). It still uses the eat.wav. Boggles the mind... I'd think food automatically uses eat.wav, but then there's wine and ale...
