Spawn Finder

Spawn Finder

Spawn Finder is a lightweight utility mod for Minecraft 1.21.1 on NeoForge designed to help players locate nearby mob spawners without adding new items, blocks, recipes, or world-generation content.

The mod scans already loaded chunks for Mob Spawners and Trial Spawners, then presents the detected results through an in-game HUD. It is intended for Survival players who want help finding spawners while still exploring the world normally, rather than using commands or external tools.

How it affects gameplay

Spawn Finder does not change where spawners generate and does not create additional spawners. It only helps the player identify spawners that already exist in loaded areas of the world.

For example, while exploring a cave system, dungeon, mineshaft, or other underground area, the mod can notify the player that a spawner exists nearby and show its distance. The player still needs to travel through the world and reach the spawner normally.

Because the mod only searches loaded chunks, it does not reveal spawners in unexplored regions or generate chunks solely for scanning.

Performance

The scanner is designed to remain lightweight. Instead of repeatedly checking every block around the player, Spawn Finder searches the block entities contained in loaded chunks and filters them for supported spawner types.

This approach reduces unnecessary scanning work and makes the mod suitable for use alongside larger modpacks.

Intended use

Spawn Finder is aimed at players who:

• enjoy Survival exploration;
• want an easier way to discover mob spawners;
• prefer not to use /locate commands or external map tools;
• want a simple spawner-finding utility without additional gameplay systems;
• use NeoForge and want functionality similar to dedicated spawner finder mods available on other mod loaders.

Supported environment: Minecraft 1.21.1 • NeoForge • Java 21
