I have a question regarding sounds. I do love my railgun on the power tool, but the sound effect it makes (the same as throwing an egg) makes sniping mobs a lot less cool. A lot. So I would like to know if it is possible to change it myself, and if so, how difficult is it? Are we talking modifying the jar here? Because I have zero experience with java, and as far as I know MPS uses no custom sounds at all. I know that with the resource packs of 1.6 it will be very easy (I presume), but not wanting to wait, I feel like tinkering a bit, unless it's way over my head.
Edit: I looked in the jar and found a sound folder, with one file called MMMPSboop.wav. I tried replacing it with another wav but then it just goes silent in the game. So it seems that it is the correct file, but either it is too long (maybe coded to only accept a certain length) or something else is wrong with my file. Any ideas?
