The question seems a bit stupid to me, since I have figured out most of the mod, I already understood how to spawn mobs in the structure, how to spawn them depending on certain player actions, but here's what I can't understand: How to make certain mobs spawn only at night? Version 1.20.1

Use mintime/maxtime and deny to deny them during daytime

This goes to spawn.json. But basically you need a rule like this:

{
  "mintime": ...,
  "maxtime": ...,
  "mob": ...,
  "result": "deny"
},

Fill in the ... I don't know what you want there

Use mintime/maxtime and deny to deny them during daytime

Sorry, can you give me an example? I didn't find them in Wiki, and I don't quite understand where exactly they should be used. I mean, I don't even understand in which file, spawn or spawner. And it seems like conditions, and it seems like restrictions.

Thank you. It remains to understand what numbers exactly need to be inserted to get the desired result.
