SpawnerHUD is a clean info layer for dungeon explorers. Point your crosshair at any monster spawner and a small readout appears in the top-left of your screen.
What it shows
- Monster Spawner — confirms you're looking at a spawner.
- Spawns: <mob> — the mob the spawner produces (Zombie, Skeleton, Spider, Cave Spider, Silverfish, Blaze…), read from the display entity spinning inside the cage. Shows (empty) for an unconfigured spawner.
Why
Vanilla only reveals a spawner's mob by the tiny rotating model inside the dark cage — easy to misread for similar mobs (skeleton vs. wither skeleton, spider vs. cave spider) and hard to see at distance or in low light. SpawnerHUD puts the mob's name on screen so you can decide instantly whether to disable, harvest XP from, or break a spawner.
Controls
- O — toggle the readout on/off. An action-bar message confirms the state.
How it's built
- Reads the spawner's displayed mob from the client-side monster-spawner block entity — no server commands, no new blocks.
- The readout only appears while your crosshair is on a spawner within range, and respects F1 (hide HUD) and open menus.
- Cross-version safe: the mob is located purely by field structure/type, with all reflection guarded.
Compatibility
