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

0.4 - Dungeon Masters and Mese Monsters have much better aim due to shoot_offset, also they can both shoot through nodes that aren't walkable (flowers, grass etc) plus new sheep sound :)
|
||||
0.3 - Added LOTT's Spider mob, made Cobwebs, added KPavel's Bee with Honey and Beehives (made texture), Warthogs now have sound and can be tamed, taming of shaved sheep or milked cow with 8 wheat so it will not despawn, many bug fixes :)
