+# Spawners #
+This MOD for Minetest let the player craft mob and ore Spawner blocks. Mobs/Ores are spawning randomly in a short intervals.
+
+From version 0.6 Pyramids can be spawned in desert and environmental spwaners are added. Environmental spawners are used for spawning inside of temples and dungeons (mapgen v6 default minetest game). - Thanks to BlockMen. These kind of spawners are very rarely dropping real mob spawners, in any other case they don't drop anything.
+
+Easy to implement new mob mods just look in to config.lua.
+New features can be enabled/disabled in settings.txt file.
+
+Currently it works with [Pyramids Mummy](https://forum.minetest.net/viewtopic.php?id=7063), [Mobs Redo](https://forum.minetest.net/viewtopic.php?f=11&t=9917) and [Creatures](https://forum.minetest.net/viewtopic.php?f=11&t=8638).

+## Changelog ##
+### 0.6 ###
+* inherited BlockMen Pyramid mod, so now Spawners can spawn Pyramids in desert (mapgen v6)
+* spawning Pyramids work independently from BlockMen Pyramids mod (can be removed) but works also besides BlockMen Pyramid mod 
+* added more various loot (default) in pyramids chests and higher up the chance of spawning more loot
+* added new environmental spawners
+* added generation of environmental spawners for default mapgen v6 temples and dungeons
+* addend new config parameter 'disable' for night_only attribute in config file
+* added new attribute 'env' in config file for defining environmental spawners
+* added settings.txt file for enable/disable new features (pyramids, mapgen spawners..)
+* fixed abm catch_up (disabled), now it works
+
+### 0.5.1 ###
+* added mobs redo stone monster spawner (re-done from BlockMen Pyramids)
+
+### 0.5 ###
+* new mobs redo sheep textures
+* added mobs redo spider spawner
+* added oerrki spawner for creatures mod
+* added screenshot and description for MODs in-game tab
+* added pyramids mod to optional dependencies
+
+### 0.4 ###
+* NEW added ore spawners - iron, gold and copper
+* ore spawners have chance to spawn 2 ores from 1 ingot
+* ore spawners have formspec
+* new sounds for ore spawners
+* added particle effect for ore spawners
+* re-done all textures from scratch (mob and ore spawners)
+* adjusted mob spawners ABM
+* added maximum stacked items for spawners to max 1
+* mob spawners fixed name conflicts in config file warthog vs. pumba
+
+### 0.3 ###
+* new folder and file structure
+* more convenient disable/enable, add/remove new MODs in config.lua file - added property for custom sounds
+* added sound for bunny
+* fixed sound for pyramids:mummy
+* added footsteps and dug sounds for the spawners
+* shorter and more effective code, easier to read, fixed variable namings
+* ABM tweak - longer delay to trigger but bigger chance for spawn entity
+* disabled ABM catch_up
+* added normal map texture for default spawner
+
+### 0.2 ###
+* support pyramids mod - mummy
+* support creatures mod
+* shorten the code - more effecient
+
+### 0.1 ###
+* Initial Release
+* detects only 6 nodes for 'air' around the spawner [top, bottom, left, right, front, back] afterwards it will check the node above and below the found 'air' node - so there is enough space to spawn someone
+* always picks random side from where the mob will spawn
+* detects for light and time of day - spawn mobs only at night if 'only_night' set to true
+* status 'waiting' - blue sparkles, for not enough light (day spawners) or too much light for night spawners
+* status 'default/inactive' i.e. if the spawner is closed from each side or there is no space to spawn mob
+* status 'active' when spawner is active and is spawning mobs
+* status 'overheat' when there is too much 'max_objects_per_block' (prevents from server errors), max value is taken from minetest.conf
+* easy to configure, add and remove MODs for mobs
+* only [Mobs Redo](https://github.com/tenplus1/mobs) from tenplus1 is added for now
+* added recipes for all spawners, it's expensive so it will not get overcrowded on the server only with spawners 
+* almost everything is done dynamically
+* spawners emit small amount of light
+* active and overheated spawner can cause fire to flammable nodes around it
+* spawners are active only if player is in radius (21)
+* spawners are diggable only with steel pickaxe and above, so no noob griefers can raid your base too easy
+* mobs play sound when spawned
+* animated textures
