General update! Well, thanks to Klemms helpful informations, i managed to make it work!... partially. TL;DR: Some lines work, others not and they are just silence. I only modified the wpk file, and all modified sound's names are the same as the old ones. How could i troubleshoot/fix this?
Well, i did a lot of stuff (i'll put up a guide if there's enough interest, once i get this right of course), and here's a nutshell of all the bogus: 1)Extracted the wems from the wpk file thanks to Woocy 2)Converted my mp3 files (ogg is fine as well) to wems thanks to WPK Packer 3)Renamed the newly extracted wems EXACTLY like the originals: say the joke file is called 9802 (it isn't, it's an example), i renamed my own wem file with a warlock joke ("My friends i'm calling it, it's IN the bag!") 9802. This may seem pointless, but it'll necessary for the next step. It IS tiring to check each file and match it with the proper file, above all because the original names are all a bunch of numbers. 4)Used WPK Packer to open the original wpk (the one with the original Annie lines). Then i set MANUALLY with "set wem" each wem with the corresponding one.
So, for example: let's say the first file after opening the ORIGINAL wpk is 9802. I'd have no idea what wem to set there... if i hadn't renamed the files in step 3! It's another tiring process, but an easy one: just write the exact numbers of the original file while browsing the folder with your modified (and renamed) wems, and you'll soon be done! 5) Save the newly set wpk with the SAME NAME as the ORIGINAL (so, in my case, Annie_Base_VO_audio.wpk), and put it in the original wpk folder replacing the original wpk file.
Now, in game... the only sounds that work are: -)AutoAttack lines -)Joke lines -)Death Lines The rest (movement, laugh, taunt, spelleffort and so on) are only made of silence. I can't get why honestly.
I don't think it's a matter of size of the files, since one joke i put there lasts 20 fucking seconds, and it plays only the first 12, so i guess if the file is too large/long the game just plays it until it can.
I also think to have got all the names right. After all, some lines work perfectly, and i all named them with the same criteria.
My biggest doubt is about if i should modify the bnk files as well, maybe they are the ones not making the sounds play in all the events, but again, io hope you can give me some insight on how to make all the sounds play in game.
