Spawn Spires

Nighttime in Minecraft is flawed. Sleeping through the night is a tedious dead man's switch that must be flipped at the end of each day, or the player is at risk of being attacked and having their builds blown up by creepers.

Spawn-proofing is a partial solution, but options are very limited and require lighting or covering surfaces in blocks that mobs cannot spawn on, which may be undesirable, and phantoms will force the player to sleep regardless. This also results in night being practically nonexistent on most servers. The game actively punishes you for engaging with nighttime as a mechanic, and Spawn Spires addresses these problems.

Spawn Spires' solution

The mod divides the world into large, invisible regions, and each region contains a Spire structure that governs the hostile mob spawning within that region. If the player climbs a Spire, they can disable the Spire Heart at the top, which will stop hostile mob spawning in the Spire's region. (mob spawns below Y=0 are unaffected, hostile mobs will still spawn in deep caves.)

(This map does not appear in-game, it's a graphic that represents the regions and the mechanic)

Sleeping in beds will no longer skip the night, and will instead slowly heal the player. You must survive through the night until you conquer the Spire in your region. In addition, insomnia is disabled and phantoms will instead spawn around active Spires, and will not burn during daytime. If the player wants to re-enable mob spawning within a region, they can simply turn the Spire Heart back on.
