|

Changelog:
|
||||
|
||||
1.26- Pathfinding feature added thanks to rnd, when monsters attack they become scary smart in finding you :)
|
||||
1.25- Mobs no longer spawn within 12 blocks of player or despawn within same range, spawners now have player detection, Code tidy and tweak.
|
||||
1.24- Added feature where certain animals run away when punched (runaway = true in mob definition)
|
||||
1.23- Added mob spawner block for admin to setup spawners in-game (place and right click to enter settings)
|
||||
1.22- Added ability to name tamed animals and npc using nametags, also npc will attack anyone who punches them apart from owner
|
||||
1.21- Added some more error checking to reduce serialize.h error and added height checks for falling off cliffs (thanks cmdskp)
|
||||
1.20- Error checking added to remove bad mobs, out of map limit mobs and stop serialize.h error
|
||||
1.19- Chickens now drop egg items instead of placing the egg, also throwing eggs result in 1/8 chance of spawning chick
|
||||
1.18- Added docile_by_day flag so that monsters will not attack automatically during daylight hours unless hit first
|
||||
1.17- Added 'dogshoot' attack type, shoots when out of reach, melee attack when in reach, also api tweaks and self.reach added
