*	initial mapgen indev version with farscale feature and huge caves	proller	2013-03-16
|
*	Migrate to STL containers/algorithms.	Ilya Zhuravlev	2013-03-11
|
*	Update Copyright Years	Sfan5	2013-02-24
|
*	Change Minetest-c55 to Minetest	PilzAdam	2013-02-24
|
*	Add flag string settings, flat map option	kwolekr	2013-02-06
|
*	Make sure that settings are written to config file when settings are removed.	Jürgen Doser	2013-01-22
| | | | |	Previously, settings where only written when a value has changed, and removal of a setting value didn't count as a change.
*	Last set of minor cleanups	kwolekr	2013-01-21
|
*	Finish and clean up mapgen configuration	kwolekr	2013-01-21
|
*	Add Settings::getStruct and Settings::setStruct	kwolekr	2013-01-21
|
*	The new mapgen, noise functions, et al.	kwolekr	2013-01-21
|
*	Basic support for configuring which mods to load for each world	Jürgen Doser	2013-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |	settings.h: added function to return all keys used in settings, and a function to remove a setting mods.{h,cpp}: added class ModConfiguration that represents a subset of the installed mods. server.{h,cpp}: server does not load add-on mods that are disabled in the world.mt file. mods are disabled by a setting of the form "load_mod_<modname> = false". if no load_mod_<modname> = ... setting is found, the mod is loaded anyways for backwards compatibilty. server also complains to errorstream about mods with unstatisfied dependencies and about mods that are not installed. guiConfigureWorld.{h,cpp}: shows a treeview of installed add-on mods and modpacks with little icons in front of their name indicating their status: a checkmark for enabled mods, a cross for disabled mods, a question mark for "new" mods Mods can be enabled/disabled by a checkbox. Mods also show a list of dependencies and reverse dependencies. double-click on a mod in dependency or reverse dependency listbox selects the corresponding mod. Enabling a mod also enables all its dependencies. Disabling a mod also disables all its reverse dependencies. For modpacks, show buttons to enable/disable all mods (recursively, including their dependencies) in it. Button "Save" saves the current settings to the world.mt file and returns to the main menu. Button "Cancel" returns to main menu without saving. basic keyboard controls (if the proper widget has keyboard focus): up/down: scroll through tree of mods left/right: collaps/expand a modpack space: enable/disable the selected mod
*	Optimize headers	Perttu Ahola	2012-06-17
|
*	Properly and efficiently use split utility headers	Perttu Ahola	2012-06-17
|
*	Switch the license to be LGPLv2/later, with small parts still remaining as ↵	Perttu Ahola	2012-06-05
| | | |	GPLv2/later, by agreement of major contributors
*	Comment out unnecessary debug output in Settings	Perttu Ahola	2012-05-20
|
*	Allow directly supplying world as a parameter, including world.mt	Perttu Ahola	2012-03-13
|
*	Clean up log messages everywhere	Perttu Ahola	2012-03-11
|
*	Do not print errors when searching for usable configuration file	Perttu Ahola	2012-03-11
|
*	Fix configuration file behaviour	Perttu Ahola	2012-03-11
| | | | |	- Do not rewrite if nothing needs to be changed - Update at program exit, in addition to updating when continuing from main menu to game
*	Some MSVC fixes	Perttu Ahola	2011-11-29
|
*	Use the logger; also, default to not showing much crap in console. Use ↵	Perttu Ahola	2011-10-16
| | | |	--info-on-stderr to enable crap.
*	mobv2	Perttu Ahola	2011-10-15
|
*	Header file tweaking; mainly for speed	Perttu Ahola	2011-10-12
