SSASpawnerAntiESP is an addon for SmartSpawner that stops players from locating spawners through walls using ESP or x-ray mods.
Instead of scanning entire chunks (like generic anti-xray plugins), this plugin only checks known spawner coordinates from SmartSpawner. That keeps server load low while still protecting hidden farms and bases.

How it works
- Loads all spawner positions from the SmartSpawner API
- Ray-traces from each player's eyes to nearby spawners
- No line of sight → the client sees a decoy block (stone, deepslate, netherrack, or end stone)
- Line of sight → the real spawner block is shown again
- On join and teleport, nearby spawners are hidden immediately to prevent flashing
Only the player's client view is changed. Server data, SmartSpawner storage, and admin tools like
/ss listare not affected.
Requirements
- Paper
1.21.11or26.1.2 - SmartSpawner (must be installed first)
- Folia supported
Download the JAR that matches your Paper version (*-1.21.11.jar or *-26.1.2.jar).
Configuration
Per-world settings for enable/disable, ray trace distance, performance tuning, and more. Reload with /ssaspawnerantiesp reload.
Limitations
- Hides the spawner block on the client — not a full anti-cheat
- Decoy blocks may not blend perfectly with surrounding terrain
- Use the correct JAR for your Paper version
