Path Finder v 0.4

[Tsunokiette]

Another In Progress Script.

Won't be the best in the world, but will use a method a little different than the others.

...So what does it do, exactly?

[Tsunokiette]

Eventually it will test all possible paths and find the shortest route, and move the event/player to the chosen position.

EDIT : @programmers - Slight rewriting needed for the add_sub definition, I'll get it done, it's just notepad is hard to program with.

EDIT 2 : As a matter of fact, I'm going to have to rewrite the Possible_Path class all together. -_-

Oh, sweet! I can think of all kinds of uses for this...
