Good morning,

Apologies if this is obvious but I have not been able to find an answer in help or through some basic searching.

Is there a sub/function that gets called on Reloading a script (not a pluginm just a script file)? ie: from the menu Game-> Reload Script file

I need to initialize some stuff when it gets reloaded and in the meantime Ive been using an alias to call the init sub.

Obligatory thanks to Nick: I've been using this for years and I rarely see software this sturdy. Thank you so much. MUSHClient runs pretty much 24/7 for me with multiple worlds, scripting and logging and I've yet to run into an issue with the client itself. Cheers for this wonderful software.

Can you use GetPluginID to detect if you're running inside a plugin and, if so, manually call OnPluginInstall at the end of your script file?

Thank you for the advice!

Unfortunately I know this is not in a plugin, it is simply a script file associated to the world under the script world properties.

Cheers

I don't understand what the problem is, then. The entire script is executed when you reload it. If you call a function at the end of it, the function will be called when you reload.

To explain a bit more: Any code, not in a function, is run the moment the script is reloaded. For example:


function foo ()
  print "Hello"
end -- foo

function bar ()
  print "World"
end -- bar

print "hi there"  --> done when script loads or reloads
foo ()            --> call foo when script loads or reloads

Ah wonderful! All my code is indeed in subs/functions , I was working under the impression I could only declare vars in the main body. Old habits from other languages.

Thanks that solves the issue fully!

Cheers

Oh my god. Nick, do you think Lua uses -- for comments so that they can draw arrows pointing at their messages? I don't know why this is just occurring to me now.

Perhaps not, but Roberto Ierusalimschy uses that concept a lot in the Lua Reference. See, for example: http://www.lua.org/pil/3.3.html
