Message:	[quote=Fadedparadox] The error "attempt to concatenate field" comes up when you try concat two things, but one isn't a string or number. The field "?" means the problem is that the item that it can't concat is in a table and what you're using to reference the key isn't a string (or is a string but is in a variable). Oddly enough, it should say "(a nil value)" but it says "(a boolean value)". The only way I could replicate that is referencing it with a boolean value, or by using a metatable so it returns false or true when it can't find what it's looking for. That's all I could figure out from the error, without seeing the script(s) itself. [/quote] Message to be posted (in English, please).

Judging by this:


[string "Plugin"]:655: in function <[string "Plugin"]:612>

Unless you have a 655 line script in a trigger, it is the plugin script itself, inside the script tag. If you used "include standard constants" you need to offset that from the count.

If inside a plugin, the line number is relative to the script inside the plugin.

If you type:


/Debug "plugins"

Then it outputs, amongst other things, the script in the plugin. With a bit of mucking around subtracting the first line from the current line, you can work out which actual line the error is in.

Thanks, I'm going to try to look at this.
But when it says script line, since the script is inside a plugin, means inside the <script> xml tag, right? or could it be inside a trigger as well.

Which version of MUSHclient are you using?

It is hard to debug without seeing the script.

Hi,
I'm trying to script something, and this error keeps coming up randomly, but when I look at the line (650-660) they make no sense and have nothing to do with the error, or at least I don't think. Here's what it says.

Error raised in timer function (in wait module).
stack traceback:
[string "Plugin"]:655: in function <[string "Plugin"]:612>
Run-time error
Plugin: AlterAeon (called from world: alter aeon)
Function/Sub: wait.timer_resume called by timer
Reason: processing timer "wait_timer_2252"
C:\Program Files\MUSHclient\lua\wait.lua:51: [string "Plugin"]:655: attempt to
concatenate field '?' (a boolean value)
stack traceback:
[C]: in function 'error'
C:\Program Files\MUSHclient\lua\wait.lua:51: in function <C:\Program
Files\MUSHclient\lua\wait.lua:43>
