Blocking Mobs and Players Using Solid Chain Railings

Understanding Chain Collision

Unlike decorative lines that entities can freely pass through, placed chains feature solid collision. When suspended between two fences or walls, the sagging chain acts as a solid physical barrier. Both players and mobs are stopped by the chain and cannot walk straight through it.

Building Functional Barriers

You can take advantage of solid collision to protect paths and keep entities contained:

• Docks and Castle Bridges: String chains between posts along high edges and water drops. The solid collision prevents players, villagers, and livestock from accidentally slipping off the ledge.
• Garden Borders and Town Pathways: Place low fences or walls connected by chains to guide foot traffic along roads without completely blocking visibility.
• Perimeter Fencing: Enclose areas to keep wandering mobs out while maintaining an open, realistic appearance.

Because the chains block movement while leaving open space above and below the sag, you gain the containment benefits of solid fencing with the aesthetic look of hanging iron links.
