| What is the world "name" referring to when using the GetWorld function?
I'm trying to use that function but I always get nil world.
The world name above where the IP address goes is cp_info. The file name for the world is cp_info.mcl. But whenever I pass "cp_info" to GetWorld it comes back nil.
This is what I'm using...
SendToWorld ("cp_info", Note("Hey"))
function SendToWorld (name, message)
local otherworld
otherworld = GetWorld (name)
if otherworld == nil then
Note ("World " .. name .. " is not open")
return
end
Send (otherworld, message)
-- alternative syntax: otherworld:Send (message)
end -- of SendToWorld

| Is the cp_info world actually open when you run this code? GetWorld only returns a reference to an open world, it doesn't open one on disk.
In the getworld.lua file which ships with recent versions of MUSHclient there is a "get_a_world" function that attempts to open the world file if it is not already open.
In that case you would do:
require "getworld"
otherworld = get_a_world (name)

You are correct, it is the world name which appears above the IP address. |

| This is really strange now.
BTW, I am using the Aardwolf mushclient, and all the included plugins are working fine (eg: stats, map, bigmap).
I started using get_a_world. It will open the world if it's not already open, BUT when it tries to use the Note() function to send to that world it comes back with World not open, or this message: Can't open world file: C:\Users\Sgbarter\Program Files\MUSHclient\worlds\Aardwolf\.mcl
(Notice it doesn't have the world name in the path?)
I have this code in the main lua script file, which I assume should be okay. The aardwolf plugins using the same functions are working, and the only difference with my code is that it's not a plugin.

| Ah, you had be puzzled for a while there.
This is how I worked it out. I changed your function to display the world name it got:
function funsend_to_world(worldname, message)
require "getworld"
wname = worldname
folder = "Aardwolf"
print ("worldname=", worldname, "wname=", wname)
local otherworld = get_a_world(wname, folder)
otherworld:DeleteOutput()
otherworld:Note (message)
end -- funsend_to_world
Forcing through a test line I saw this:
worldname= Cpinfo wname= Cpinfo
worldname= wname=
Can't open world file: C:\Program Files\MUSHclient\worlds\Aardwolf\.mcl
Run-time error
First time the world name was right, but what was the second time?
Then I spotted it. You are calling the script twice:
<triggers>
<trigger
enabled="y"
match="^You are friends with \:"
omit_from_output="y"
regexp="y"
script="funsend_to_world"
send_to="14"
sequence="100"
>
<send>funsend_to_world("Cpinfo","HEY")
</send>
</trigger>
</triggers>
If you are using "send to script" you don't also place the function name in the script box.
Delete the line:
script="funsend_to_world"
That was calling your function without sending "cpinfo" down to it, and thus it couldn't open the world.
