GLASS Reforged

Security cameras that work like windows. Put a terminal somewhere, build a screen in a wall somewhere else, and the wall shows you what the terminal sees - shifting correctly as you walk past, so it reads as a hole through to another place rather than a picture of one.

Setting one up

1. Place a GLASS Terminal where you want to look from, and right-click it to name the channel.
2. Place a GLASS Projector in the wall where you want the picture, and pick that channel from the list.
3. Give the projector redstone. The picture spreads into any GLASS Extension blocks touching it - up to 40 - which all become one screen with no join showing.

Punch an active screen and the picture ripples where you hit it.

The same screen from off to one side.

Three kinds of screen block

• Extension - the ordinary one.
• Phantom Extension - no collision, so you can walk straight through the picture.
• Wireless Extension - does not need to touch the projector at all.

Before you build one

• No other mods needed - the original's iChunUtil dependency is gone.
• It does not work with shader packs. Screens will not draw under Iris, Oculus or OptiFine.
• On a server it goes on the server and every client, but the picture is made entirely on your machine.
• The terminal has to be in your loaded chunks, same as the original.
• Unlike the original, you can see yourself on camera.

The mod and its whole design are iChun's - General Layman's Aesthetic Spying Screen, originally for 1.12.2. This is a port to modern versions, LGPL-3.0 like the original. Recipes are unchanged; the phantom extension is the one new block.

Forge 1.20.1 and NeoForge 1.21.1. Client and server. LGPL-3.0, same as the original. Free to use in modpacks.
