Stay Night - Permanent Midnight Mod

Overview
Stay Night is a lightweight Minecraft mod that forever locks your world at midnight (tick 18000), creating a permanent night atmosphere perfect for horror maps, vampire roleplays, or players who prefer the mysterious ambiance of darkness. This mod seamlessly overrides time mechanics on both client and server sides to maintain eternal night.

Key Features

🌙 True Permanent Night

Forces all worlds to remain at 18000 ticks (midnight) regardless of time commands, sleep attempts, or natural cycles.
Works in both singleplayer and multiplayer environments.

🛡️ Comprehensive Time Control

Intercepts time-setting logic in:
- World data (PrimaryLevelData, DerivedLevelData)
- Client/Server level handlers (ClientLevel, ServerLevel)
- Network time-sync packets (ClientboundSetTimePacket)
Blocks all attempts to modify the time of day

⚡ Zero Configuration
Instantly works upon installation - no configs or commands needed!

🧩 Compatibility
Compatible with most mods that don't directly alter time mechanics.

Technical Implementation

The mod uses bytecode manipulation to:

Override time setters

@ModifyVariable(method = "setDayTime", at = @At("HEAD"), argsOnly = true)
private long stayNight(long dayTime) {
    return 18000L; // Always force midnight
}

Hijack time getters

@Inject(method = "getDayTime", at = @At("HEAD"), cancellable = true)
private void stayNight(CallbackInfoReturnable&lt;Long&gt; cir) {
    cir.setReturnValue(18000L); // Always report midnight
}
