Laser Bridges & Doors
Laser Bridges & Doors adds laser source blocks that form bridges, doors and fences when a redstone signal reaches them.
What it does
A laser source block projects a laser across empty space when it receives a redstone signal. The laser forms a platform the player can walk on, or a door or fence depending on the chosen source block. Its length follows the strength of the signal and updates as that strength changes, so a weaker signal produces a shorter beam. The mod requires Deimos on every loader, and it is published for Fabric, Forge, NeoForge and Quilt across 32 release versions, 1.18 – 26.3.
Laser sources can be dyed by clicking them with a dye in hand or by feeding dye into a dispenser. Full block laser sources can be combined into more complicated redstone circuits. The mod is open source under the MIT License, and its source code is publicly available. Because the environment is client and server, the server and every player need the mod installed.
Key features
Laser platforms
Powered laser sources create walkable platforms that appear and disappear with the redstone signal.
Variable beam length
The length of each laser changes with the strength of its signal, and it updates while the signal changes.
Dye coloring
Laser source blocks take dye by click or from a dispenser, so builds can be color coded.
Crafting recipes
A Laser Source Block is crafted from glass, iron ingots and an End Crystal, and it converts to and from a Laser Fence Source Block.
Configurable limits
The maximum laser length and the list of blocks a laser can cut through can both be set in the config, with a default length of 15.
