About this project

What does Glass only Player can pass add?

Overview

Lapis Phase Glass introduces three specialized, vanilla-friendly glass blocks infused with Lapis Lazuli, Soul Sand, and Redstone. Whether you are building a doorless base entrance, a safe mob farm viewing window, an automated mob sorter, or a redstone-controlled security barrier, these blocks give you total control over who—and what—can walk through your walls.

Blocks & Mechanics

Block Name	Block ID	Passable By	Blocked By	Special Mechanic
Lapis Phase Glass	`lapis_phase_glass`	Players	All Mobs	Default player-only barrier
Mob Phase Glass	`mob_phase_glass`	Mobs and Items	Players	Inverted collision filter
Redstone Phase Glass	`redstone_phase_glass`	Players (Unpowered)	All Entities (Powered)	Locks solid with redstone

Lapis Phase Glass: Walk straight through your walls while keeping Creepers, Zombies, and other mobs completely locked out.
Mob Phase Glass: Inverts the phase polarity so mobs, animals, and dropped items pass through freely while players are treated as hitting a solid glass wall—ideal for mob grinders and breeding pens.
Redstone Phase Glass: Functions like Lapis Phase Glass when unpowered, allowing players to pass through; once powered by a redstone signal, its phase locks and it becomes solid to everyone, including players.

Key Features

Zero Suffocation: Players and mobs never take suffocation damage while standing inside any Phase Glass block.
Spawn-Proof Surface: Hostile mobs cannot naturally spawn on top of Phase Glass blocks.
Clean Translucent Visuals: Retains vanilla glass sound effects, mining speed, and translucent rendering across all supported loaders.
Multiplayer & Server Safe: Built with clean client/server separation so it runs smoothly on both singleplayer worlds and dedicated servers[cite: 17, 18].
