When something like that happens it helps to put "check" around the function to see what the error message is, eg.


check (PlaySound (1, "c:\bombalarm.wav", false, 0, 0))
check (Sound("c:\bombalarm.wav"))

In your case I'm guessing you would see:


Run-time error
World: xxxxxx
Immediate execution
[string "Command line"]:1: Cannot open the specified file

The reason is the lack of backslashes. First, inside a Lua string you need to change \ to \\. Second, inside "send to script" you have to double them again because MUSHclient also converts backslashes. So assuming the file is there and is the right format, you at least need:


PlaySound (1, "c:\\\\bombalarm.wav", false, 0, 0)

Or save yourself some effort and use forward slashes:


PlaySound (1, "c:/bombalarm.wav", false, 0, 0)

thanks Nick, that did it this is not for me but for a hard headed pal lol, so forward slashes it is, trying to explain him about escaping backslashes and parsing would be very very hard :P

What might be simpler for your friend is, put the sounds in the MUSHclient "sounds" folder. See here:

http://www.gammon.com.au/scripts/doc.php?function=PlaySound

To quote from that page:



If the file name is a fully-qualified path name (ie. it starts with a slash, or a drive letter, colon, slash like "C:/") then it is used "as is".



Otherwise, MUSHclient prepends the MUSHclient execution directory + "sounds" subdirectory to the name



For example, the file name "swordhit.wav" would be looked for at: C:/Program Files/MUSHclient/sounds/swordhit.wav



You can use forward slashes in the file name (for convenience in typing strings in scripts), they are converted to backslashes.

So if you use the sounds folder then you don't need slashes of any kind. That is:


PlaySound (0, "bombalarm.wav")
