Re: [tf-dis] Capturing a gagged line in a variable

You need to create a new evaluation scope so that %{world_name} will be
substituted with its value in time to act as part of the room_X variable
name.  Like so, for example:

/eval /set room=%%room_%{world_name}

When the hook fires, a scope is created and substitution is performed on
the hook body, turning that line into this:

/eval /set room=%room_WORLD1

Then, /eval creates a new scope and substitution is performed again,
turning it into this:

/set room=My Room

On a side note, macro substitution is generally a strange thing to do in an
expression, but it works here thanks to some special cases for world fields
(which I didn't know about before, so thanks!).  A nicer way to do it in an
expression would be with the world_info function:

/set world_name=$[replace("-", "_", world_info())]%; \

But then, this is a WORLD hook, so the world name is already passed as the
first argument.  You can use %1 instead (Or {1} since it's in an
expression).  Here's how I would write your hook (I always use /def, mostly
so I can name things, but that's entirely up to you):

/def -hWORLD setRoomWorldHook = \
    /set world_name=$[replace("-", "_", {1})]%; \
    /eval /set room=%%room_%world_name

I recommend you read the /help on: scope; evaluation; percent compression;
substitution; expressions.
