Firstly, I've implemented a reusable 'conditional' mechanism that I hook
in in quite a few places. Conditional descriptions are just on of the
places it is used. Each condition specifies an entity (world, actor,
observer etc), an item to check (skill, time, spell_affect) and one or
two values to chack against.
The sword starts with its name - sword steel
Then it has a long description - A fine blade of polished steel
Then it has a set of extended descriptions, using it's name as the key.
Each may have one or more optional conditions specified.
'It looks quite sharp.'
Condition: actor->skill->sword 0 15
'It has a razor honed edge and is undoubtably the work of the weapon
smiths of FooBar. This is a rare and valuable blade.'
Condition: actor->skill->sword 16 -1
'You can see glowing runes within the sword.'
Condition: actor->is->detect_good
When you examine the sword it also runs a check through the extra
descriptions to see which other ones you can see. For rooms, the
constant string 'room look' is used.
Recording of things is done via an 'deed' mechanism which remembers
things that have been done. A deed condition (actor->deed->deed_vnum)
is used to pull it into the checks.

Hmmm. This sounds interesting. Are you using just forward feed nets or
do you allow feedback loops?

How many Crays do I need to run it? Quake seems to have problems with
more than 10-15 players over the net...
Do you guarentee that everyone in the same room at the same time sees
the same thing? Or can some be looking at a plastic chair while others
are looking at a golden throne?
