I guess, that after putting an emerald block villagers have to spawn.
I did everything using a wiki, but after a few attemps nothing happend.
Maybe i made a mistake.
In potentialspawn.json i wrote this:
{
"dimension": 0,
"mobs": [
{
"mob": "minecraft:villager",
"weight": 5,
"groupcountmin": 1,
"groupcountmax": 5
}
]
}
And villagers began to spawn in enormous amount everywhere, but after adding to spawn.json this:
{
"mob": "minecraft:villager",
"block": "minecraft:emerald_block",
"mincount": 1,
"maxcount": 5,
"result": "allow"
},
{
"mob": "minecraft:villager",
"result": "deny"
}
They stopped spawning at all (nor on the grass as they did before nor on the emerald blocks)
Any suggestions?
P.S. Thanks for any help!

By combining 'mincount' and 'maxcount' that rule will never fire. Only use maxcount. The 'mincount' 1 prevents the rule from working if there is no villager in the world

I will try now.

Thanks, it works.
