Spawn Spires

The mod addresses the way nighttime monster spawning is handled in vanilla Minecraft. Sleeping skips the night only when every player is in bed, which can leave a world with almost no night at all on busy servers. Spawn-proofing is a partial fix, since it needs lights or covered surfaces, and phantoms still punish players who stay awake. Spawn Spires aims at these problems by letting a player choose when night mobs appear.

A Spire is a structure that generates in the overworld. Its region is set by the chunks around the Spire, and a map in the game shows the regions as a graphic. Inside a region the player must survive through the night until the Spire is conquered. Insomnia is disabled, and phantoms spawn around active Spires and burn during the day instead. Once a Spire is conquered, a player can turn mob spawning back on in its region by turning the Spire Heart back on.

Spawn Spires works with overworld biome mods. Its Spire generation depends on biome tags, so newly added modded biomes must be listed in the mod's configuration before the mod can place a Spire there. The mod tries to place a Spire in each biome from its list. Spires that fail to generate are given a Spire Heart that can be placed by commands in creative mode. The mod is only meant for new worlds, and a chunk that was generated before the mod was installed keeps its normal monster spawning.
