I can't make the monsters spawn on the ice

[Windavilin]

I have tried using the "norestrictions" option in spawner.json together with block filters in spawn.json to allow monster spawning on ice surfaces, however, it doesn't seem to work.It's anything wrong?

spawn.json
spawner.json

Minecraft version is 1.20.1 Forge 47.4.0, and the mod version is InControl 1.20-9.4.6.

A few remarks. First get rid of all the "minlight": 0 lines. That's overhead for no reason because light is always minimum 0.

Secondly. I don't see these block filters for ice in spawn.json?

Thirdly, can you describe better which mob it is that isn't spawning? Be specific

[Windavilin]

Thank you very much for your correct.Now I deleted all the "minlight": 0 lines.
{
"when": "onjoin",
"hostile": true,
"block": {
"tag": "forge:danger"
},
"result": "allow"
},
here,I added ice with the tag"danger".
{
"mob": ["minecraft:zombie_villager","minecraft:stray","born_in_chaos_v1:barrel_zombie"],
"weights": [10,3,2],
"persecond": 0.006,
"attempts": 10,
"amount": {
"minimum": 3,
"maximum": 6
},
"conditions": {
"dimension": "minecraft:overworld",
"norestrictions":true,
"mindist": 16,
"maxdist": 32
}
},
I wrote these in my spawned.json,but I couldn't see zombie_villager,stray and barrel_zombie spawning at the ice.

Your persecond is extremely low. And your attempts too. Basically it will only try 10 times to spawn the mob every 3 minutes. That's why you are not seeing anything. You should significantly raise persecond and attempts

[Windavilin]

I'm sorry.But even if I raised persecond to 1,there is nothing happened.
Relatively, monsters can be generated normally on other blocks.

[McJty]

Show me your full spawn.json and spawner.json

[Windavilin]

ok.

spawn.json

spawner.json

[McJty]

You said you deleted all "minlight":0 lines but that is clearly not the case? Are you giving me the correct spawn.json?

[Windavilin]

Sorry,now is correct.

spawn.json

[McJty]

Also you deny hostile mobs to spawn on ice. So why do you expect them to spawn? I'm a bit confused:

  {
    "when": "onjoin",
    "hostile": true,
    "block": {
      "block": "minecraft:ice",
      "offset": {
        "y": -1
      }
    },
    "result": "deny"
  },

[Windavilin]

I apologize for making such a careless mistake. My configuration should be correct now, but under these circumstances, I still cannot see any monsters spawning on the ice. Please help me figure out what the issue might be when you have time. Thank you very much for your patience!
