[2023] Blood moon spawns inside base

How big of a base do you have..?

In any case, The zombies currently spawn around 50~ blocks out from your location, ish. Given the default zombie spawn total of 8, if they spawned much further than that, you'd basically only ever have one or two zombies active at your door, and the other 6-7 way out away from your base on their way back from respawning, just taking up pathing space for no real reason. Spawning them such a distance away too would require more active loading of those regions rather than just having it prepped and ready for you to travel into them; And also would require increasing the size of the AI's pathing grid to compensate (since blood moon hordes always know where you are; their pathing area must be large enough to contain the player from the range at which they spawn.), which would increase performance costs of the AI.

It's just.. Not really a good deal to make them spawn further away, in any aspect.

Originally posted by Spirit Wolf: So, if you are in a deep cave base. Will the blood moon horde spawn in the ground 50 blocks from ya or just spawn above trying to dig to you?

Above, and they will absolutely dig down to you. Even if you make a big hollow room, i dont think they can spawn underground (Never really tested though.)

Yea, but the blood moon horde is immune to its effects. I think screamer spawns might be too.

Correct. The LCB and Bedroll have only ever stopped POI spawns. Biome, screamer, and bloodmoon spawns are not affected by them.

This has not been true since like Alpha 7.

Before Alpha 17 you could just fill the void with frames and then pick it up to kill the sleeper blocks, but that went away with the new volumes.
