SpawnerLoader9000
by ThatMG393
SpawnerLoader9000 keeps a spawner active when players are far away, loading the chunks around it so its mobs keep spawning.
What it does
A spawner that has been activated by the mod stays loaded even when no player is nearby. The mod loads a 3x3 chunk area around the block, so entities spawned there are not unloaded at once. The loading applies only while a block sits above the spawner and the 5x5 chunk area around it is present. Right-clicking the block with an item in the middle, or with the middle mouse button, toggles the feature, and it starts switched off until enabled.
The mod runs on Fabric and is server-side only, so only the server needs it and players join without installing anything. It requires Fabric API. Files are published for Minecraft 1.21 – 1.21.3, and the latest file is 0.0.2+release.2 for 1.21.3, dated 2024-11-18. The mod is released under a custom license and is not open source, though its source code and issue tracker are public.

Use cases
Remote mob farms
A farm far from the player keeps spawning mobs while the player is away, since the spawner stays loaded.
Server-side setup
Server owners add the mod to a Fabric server, with players joining without any client installation.
Who it’s for: The mod suits server owners who want spawners to keep working in areas players have left. It is server-side only, so it fits servers whose players use vanilla clients.

What the author says
Loads your spawner even when you're far away. I got the motivation to create this mod because the mod Scarecrows' Territory, isn't Vanilla compatible.
