Phantom Portals

By StarRinth

What is Phantom Portals?

Phantom Portals is a lightweight Paper plugin designed to protect your server's Nether portals from exploitation. When a Nether portal is outside of a player's direct line of sight, it becomes hidden by being replaced silently with stone. The moment a legitimate player looks at it, the portal is seamlessly restored.

This makes it significantly harder for hacked clients using X-ray, ESP, or other visibility exploits to locate and abuse Nether portals across your world.

How It Works

Phantom Portals continuously monitors all tracked Nether portals on your server. Using a combination of distance checking, raycasting, and field of view detection, it determines whether any online player can genuinely see a portal at any given moment. If no player can see it, the portal is hidden. If a player looks toward it, it comes back — instantly and seamlessly.
