teleport from one location to another(think halo or portal)
"""

###Summary###
#this allows the server admin to declare locations in the map config file
#there can be single, multi, one-way portal links

#the algorithim I use seaches the map config for the first location that matches
#the players coordinates. if it finds a match is will then pick a random tuple
#or int from the same group this(50,14,30) is a tuple and this(4) is an int
#the integers are used to make one-way links

###Important###
#you may modify this file, however you still have to leave the 'by Desert Storm'
#part at the top of the file AND
#give credit to me if you post this elsewhere

###Notes###
#define the location so that there is one block of air between the location
#and the ground

#this does NOT check for anything lower than 2 or higher than 60

#for the one-way link the '#' is any existing index point in the 'otps'
#decleration

#you can have no less than two declarations in a group otherwise this will
#raise an Exception

#having dipped my spoon in to assembly language I know how important
#optimization is, so I have tried to make this use as little memory as I can
#with my current knowledge of python

###Examples###
#your config file can be any combination of the following

#map config file look:
#name ***
#author ***
#version ***
#description ***
#extensions = {'tps':[(())],
#              'otps':[()]
#             }

#Normal link:
#extensions = {
#             'tps':[((x1,y1,z1),(x2,y2,z2))]
#             }

#multiple groups:
#extensions = {
#             'tps':[((x1,y1,z1),(x2,y2,z2)),((x3,y3,z3),(x4,y4,z4))]
#             }

#multi link:
#extensions = {
#             'tps':[((x1,y1,z1),(x2,y2,z2),(x3,y3,z3))]
#             }

#one-way link:
#extensions = {
#             'tps':[((x1,y1,z1),(#))]
#             'otps':[(x2,y2,z2)]
