*	Reduce ServerEnvironment propagation (#9642)	Loïc Blot	2020-04-11
| | | | | | | | | |	ServerEnvironment is a huge class with many accessors. In various places it's not needed Remove it to reduce the ServerEnvironment view. Idea here is to reduce size of some of our objects to transport lightweight managers and permit easier testing Pathfinder is now tied to a generic map, not a ServerMap, it can be ported to client
*	C++ modernize: Pragma once (#6264)	Loïc Blot	2017-08-17
| | | |	* Migrate cpp headers to pragma once
*	Pathfinder: Fix style	est31	2016-05-01
| | | | | | | | | | |	* Fix naming style for methods and classes: Use camelCase for methods and PascalCase for classes as code style demands it. And use sneak_case for methods that are not member of a class. * Replace "* " with " *" for Pointers * Same for references * Put function body opening braces on new line * Other misc minor non functional style improvements
*	Move pathfinder classes to cpp file	est31	2016-05-01
| | | | | | | | | | | | | | |	There is no need to put them into the header, they are solely used inside the pathfinder. Another advantage of this change is that only the pathfinder.cpp has to be compiled if PATHFINDER_DEBUG gets defined or undefined, not all files including the .h. This commit moves the pathfinder classes to the cpp file without modifications. Also, the PATHFINDER_DEBUG macro gets moved to the cpp file and the PATHFINDER_CALC_TIME macro gets moved to a plce where it actually does work.
*	Omnicleanup: header cleanup, add ModApiUtil shared between game and mainmenu	Kahrl	2013-08-14
|
*	Add Dijkstra A* and A* without prefetching pathfind algorithms	sapier	2013-04-06
