============
Maplinks - version 0.95 (2005-11-10)
============
by Wachunga
This script simplifies linking maps together: a single event sets up an
entire edge of the map as a teleport to another map. Players trying to
leave that edge of the current map are automatically teleported.
(This can also be achieved with many copies of teleport events along the edges
of a map or with a parallel-process event that sets variables and uses them to
teleport, but these methods are not optimal -- causing lag and/or inconvenience
for the mapper.)
To link a map with another on a specific edge (north, east, south or west),
create an event with <maplink> included in its name on the appropriate edge of
the map. (To avoid confusion, maplink events on corners of the map are
not valid.) Then, add a teleport ("Transfer Player") command to the event
to specify the destination map and other details (e.g. player direction,
fading on/off). If the destination is an east or west edge, then the Y
coordinate is calculated based on the player's Y coordinate when
teleporting; likewise, the X coordinate is calculated automatically when
the destination is a north or south edge.
Note: unlike normal teleport events, maplinks are activated when the player
tries to leave the screen instead of when stepping on the last tile. This
behaviour could be changed, but I feel that it's more natural this way:
it leaves the whole map open for actual exploration, instead of "wasting"
the outer tiles of a map.
