What is Bloodmoon?
When the Blood Moon rises, the night stops being “routine Minecraft” and becomes a threat you can feel: the atmosphere shifts, the danger ramps up, and you get a clear on-screen warning that something bad just started.
It’s built to fit survival/hardcore worlds where you want nights to matter again, without needing any external APIs or dependencies—just Forge 1.20.1.
Core features
-
Blood Moon event that can start on selected nights (periodic logic and/or forced triggers depending on your setup).
-
Server-controlled state with client sync, so multiplayer stays consistent (everyone sees the same event timing).
-
Increased hostile pressure during the event (extra spawn attempts / spawn behavior tweaks depending on your configuration).
-
A cinematic HUD overlay sequence: the moon drops in smoothly, the Blood Moon symbol reveals behind it, the moon fades, then after a short delay the blood overlay slides down and disappears.
Gameplay vibe
Bloodmoon isn’t meant to be “more mobs for free loot”—it’s meant to create tension: you’ll rethink traveling at night, securing your base perimeter, and lighting up the land around you.
Because Minecraft runs on a tick-based game loop (commonly treated as 20 ticks per second), the event timing and overlay animation can be made consistent and smooth across machines.
