Laser Bridges & Doors guide for FTB Skies 2: Aero 1.0.3 to 1.5.1

Same as in the All the Mods 10 2.38 guide

Laser Bridges & Doors is a small, decorative redstone mod that gives you futuristic laser bridges, doors and fences. You place a laser source block, give it a redstone signal, and it projects a laser structure outward. This pack ships version 1.21.1-1-neoforge of the mod.^[1][2]

How it works

• The laser only forms while the source block is powered by redstone, so a lever, button or pressure plate is enough to open and close a laser door or bridge.^[1]
• The length of the laser depends on the redstone signal strength and updates as the signal changes. A weaker signal gives you a shorter bridge.^[1]
• You can recolor a laser source by clicking it with a dye in hand, or have a dispenser apply the dye for you.^[1]
• There are full block laser sources for more complex redstone contraptions, plus a Laser Fence Source Block variant for laser fences.^[1]

The mod is configurable. One option sets the maximum laser length at full power, and all partial lengths are calculated from it. The mod's own default is 15 blocks. Another option lists the blocks that lasers are allowed to cut through and replace.^[1]

Unverified The sources don't confirm whether this pack keeps the mod's default maximum laser length or changes it. Test it in game before you plan a long bridge.

Who it's for

If you like building bases with a sci-fi look, secret entrances or redstone-controlled walkways, this mod is for you. Its job is style and redstone fun rather than tech or resource progression.^[1]

Unverified The sources don't document a place for this mod in the pack's progression, and no in-pack recipe for the laser source blocks could be confirmed. Check the recipe viewer in game. This site does hold FTB Skies 2: Aero's own recipes, read from the pack itself: look the item up in the item browser.

The mod has only two config options, both in config/laserbridges.json. You can change them in-game or by editing the JSON file directly. Here is what each one does and how this pack sets it.^[1]

Maximum laser length

max_length is the longest laser a fully powered laser source block can produce. Shorter lasers are calculated from this value, so changing it rescales every bridge, door and fence. Laser length depends on the redstone signal strength, so a weaker signal gives a shorter laser.^[1]

This pack sets it to 15, which is also the mod's default. The pack did not change this value, so a fully powered source reaches 15 blocks.^[1][3]

Blocks lasers cut through

blocks_cut_through_by_lasers is the list of blocks a laser can replace instead of being stopped by them. Anything not on the list blocks the laser.^[1]

In this pack the list contains these blocks:^[3]

• Air, cave air and void air, so lasers pass through empty space in any dimension or cave.^[3]
• Short grass and tall grass.^[3]
• Fern and large fern.^[3]
• Dead bush.^[3]

Unverified The sources do not show the mod's default for the cut-through list, so we can't say whether the pack changed it.
