} As I understand your question, I don't. As I say "room" is too narrow a
} term. My model is a world of nested containers, each iwth acoordinate
} system. If you want something like a voice to be heard in multiple places,
} or an arrow to arch across an area, the areas in questio nare all part of
} the same "container" and exist in the same coordinate space.
}
} As an example... a large expanse of desert might all be one container. The
} streets of a city m,igth be another container. Inside a bar in the city is
} in a third conatiner.
}
} The whole purpose of containers is to cut down on the interraction between
} players where logical and reduce the n-square problem. (Actually, thats not
} entirely true, my parse system is also inhearently tied to the container
} hirearchy.)
Consider:
+---------------------------------------+---------------+ N
| | | ^
| [A] Grassland [B] | [C] Forest | / \
| | | |
+---------------------------------------+---------------+ |
Alfred is in the grassland. Position[A] = (30,30).
Bubba is in the grassland, near the forest. Position[B] = (200,30).
Calvin is in the forest. Position[C] = (230,30).
How will the program handle the following scenarios:
* Bubba sees Alfred ("in the distance") but not Calvin.
* Bubba says "hi". Calvin hears him but Alfred does not.
* Bubba screams "H-E-L-P". Calvin and Alfred both hear him.
* Calvin shoots an arrow to the west, which arches over Bubba
and accidently hits Alfred.
* Calvin walks west.
Bubba sees a message "Calvin arrives ...". Alfred does not.
In a purely "container-based" setting, $Calvin would send a message to
$Grassland which would, in turn, send messages to $Alfred and $Bubba.
} >What algorithms do you use?
}
} Um... thats BIG question. All code is algorithymic. Im not sure what your
} question is here...
I meant data structures to represent spatial relationships and algorithms to
compute message recipients.
Have fun,
Alex.
