讨论 求助！Feature rules json

[cty_4373]

小弟最近有自学制作资源包，并在尝试制作一个自定义矿石的资源包。我在编写 feature_rules时遇到问题
my_ore_feature_rules.json︰
{
"format_version": "1.13.0",
"minecraft:feature_rules": {
"description": {
"identifier": "cty:my_ore_feature_rules",
"places_feature": "cty:my_ore_feature"
},
"conditions": {
"placement_pass": "underground_pass",
"minecraft:biome_filter": [
{
"any_of": [
{
"test": "has_biome_tag",
"operator": "==",
"value": "overworld"
},
{
"test": "has_biome_tag",
"operator": "==",
"value": "overworld_generation"
}
]
}
]
},
"distribution": {
"iterations": 3,
"coordinate_eval_order": "zyx",
"x": {
"distribution": "uniform",
"extent": [ 0, 16 ]
},
"y": {
"distribution": "uniform",
"extent": [ 0, 35 ]
},
"z": {
"distribution": "uniform",
"extent": [ 0, 16 ]
}
}
}
}





无论怎么改，我始终在地下找不到我的矿石有生成。我希望我的矿石能弄成像煤炭一样常见，请问是哪部份有问题/如何弄到像煤炭一样常见呢？
