I want to replace some of the snd files for doors etc for some of my levels. Please note that I am using JKedit full as my level creator but my problem is, I don't know what I need to convert wave files to snd.

Can someone help me out here? I tried using search here but was unable to find anything.

wave files dont get converted into snds.

Listen up.

Put your new wav files for the door in C:\JkEdit\YourProject\sound" folder.

then use this
## action wavefile flags min dist max dist max volume
startmove door_big_open.wav 0x0 0.1 1.0 0.4
stopmove door_big_close.wav 0x0 0.1 3.0 0.7
moving door_big_move.wav 0x0001 0.1 2.0 0.9

copy that into a notepad and save it as something like "mynewdoor.snd" and save it in the C:\JkEdit\YourProject\misc\snd folder

open up a normal JK door in JKEDIT template changer (dont know about JKEDIT?) and change the line soundclass=door.snd to soundclass=mynewdoor.snd

thats pretty much it i reckon.

For a full llist of details on snds, wavs, etc, download jkspecs

if(getThingFlags(source) & 0x8){
  do her}
elseif(getThingFlags(source) & 0x4){
  do other babe}
else{
  do a dude}

Unfortunately that's the easy Jed way, in JKEdit you'll need to make the snd file like Ruthven said, then import every sound file (wav and snd) using JKEdit's file import stuff. And I suggest making a new template based on a door, it's not good practice to overwrite the LEC stuff.
