Hallo,
Ich und Testperson sind gerade dabei eine mittelalterliche Stadt zu bauen, die dann später auch mit Dorfbewohnern belebt werden soll.(Keine Sorge, sie ist extra weit weg vom Spawn, damit es nicht so lagt). Am Rand gibt es eine 3 Blöcke Dicke Wand, damit die Villager nicht ausbrechen können. Sie handeln aber bisher viel zu OP. für etwas Weizen bekommt man schon 1 Smaragd, was ja viel mehr ist, als ein Dia. Deshalb habe ich mir überlegt, den Villager Code etwas abzuändern. Jetzt handeln sie mit coins und auch zu viel faireren Preisen.

Code: Select all

--MCmobs v0.4
--maikerumine
--made for MC like Survival game
--License for code WTFPL and otherwise stated in readmes

--###################
--################### VILLAGER
--###################
-- Summary: Villagers are complex NPCs, their main feature allows players to trade with them.

-- TODO: Particles
-- TODO: 4s Regeneration I after trade unlock
-- TODO: Breeding
-- TODO: Baby villagers
-- TODO: Spawning in villages
-- TODO: Behaviour:
--     TODO: Walk around village, but do not leave it intentionally
--     TODO: Run into house on rain or danger, open doors
--     TODO: Internal inventory, pick up items, trade with other villagers
--     TODO: Farm stuff

local S = minetest.get_translator("mobs_mc")
local N = function(s) return s end

-- playername-indexed table containing the previously used tradenum
local player_tradenum = {}
-- playername-indexed table containing the objectref of trader, if trading formspec is open
local player_trading_with = {}

local DEFAULT_WALK_CHANCE = 33 -- chance to walk in percent, if no player nearby
local PLAYER_SCAN_INTERVAL = 5 -- every X seconds, villager looks for players nearby
local PLAYER_SCAN_RADIUS = 4 -- scan radius for looking for nearby players

--[=======[ TRADING ]=======]

-- LIST OF VILLAGER PROFESSIONS AND TRADES

-- TECHNICAL RESTRICTIONS (FIXME):
-- * You can't use a clock as requested item
-- * You can't use a compass as requested item if its stack size > 1
-- * You can't use a compass in the second requested slot
-- This is a problem in the mcl_compass and mcl_clock mods,
-- these items should be implemented as single items, then everything
-- will be much easier.

Könntest du vielleicht die Datei in Minecloneverzeichnis/mods/ENTITIES/mobs_mc/villager.lua
so abändern? Dann könnte man sie , auch wenn sie noch WIP sind schon benutzen. Die würden dann Leben in das Dorf bringen und andere Könnten auch mit ihnen handeln.
