One Way Invisible Block
One Way Invisible Block adds a block that lets players walk through one side while the other side stays solid.
What it does
The block is invisible and passes through from one side only, so a wall built with it can be entered from one direction and blocks the other. Builders use it for hidden passages, secret entrances and barriers that do not change how a space looks. Servers that run it need every player to install it too. Files are published for Forge only, across six game versions: 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5 and 1.20.6. The mod is not open source and is covered by All rights reserved.
Key features
One-way passage

Invisible appearance
The block does not alter lighting or the look of the surrounding world, so hidden routes stay hard to spot.
Barriers for maps
Suited to secret entrances, security systems, adventure maps and minigame arenas.
