Laser Bridges & Doors guide for All the Mods 10 2.39 to 7.3

Laser Bridges & Doors adds laser source blocks that project futuristic-looking laser bridges, doors and fences when you power them with redstone. It's a small, focused mod for builders and redstone fans who want sci-fi walkways, force-field style doors or glowing fences in their base.^[1]

All the Mods 10 7.3 ships version 5.3 of the mod, and it has been in the pack since version 2.25 or earlier.^[2]

How the lasers work

• A laser only appears while its source block gets a redstone signal, and its length follows the signal strength, updating live as the signal changes.^[1]
• You can color a laser source by clicking it with a dye, or have a dispenser apply the dye for you.^[1]
• Full block laser sources are there for more complicated redstone contraptions.^[1]
• A Laser Source Block and a Laser Fence Source Block can be converted into each other in the crafting grid, in either direction.^[1]

Configuration

You can change the mod's settings in-game or in its config file. The max_length option sets how long a laser gets from a fully powered source, and shorter lengths are scaled from that value. The mod's default is 15 blocks. Another option lists which blocks lasers are allowed to replace.^[1]

Unverified The sources don't confirm whether All the Mods 10 changes the maximum laser length or the crafting recipes. Check in-game before planning a long bridge.

Laser Bridges & Doors adds futuristic laser bridges, doors and fences that form when you power a laser source block with redstone. Getting started is simple: you craft one block, and the rest of the mod's features come from that block.^[1]

First, craft a Laser Source

Your first item is the Laser Source. All the Mods 10 changes the mod's crafting recipe for it, so use the in-pack version rather than the one on the mod's own page. The pack also adds a second recipe for the same block that accepts any glass block, so you aren't locked into one specific type of glass.^[3]

Next, power it with redstone

Place your Laser Source and give it a redstone signal. That activates it and forms the laser. The laser's length depends on the strength of the redstone signal and updates dynamically, so you can extend or shrink a bridge just by changing how much power you feed it.^[1]

Switch to a fence if you need one

Want a laser fence instead? Put your Laser Source in the crafting grid on its own to turn it into a Laser Fence Source. The conversion works in both directions, so you can always switch back.^[1][3]

Make it look good

To color a laser source block, click it while holding a dye. You can also apply the dye with a dispenser.^[1]

Unverified The sources don't explain how the mod decides whether a powered source forms a bridge or a door, for example based on which way the block faces. They also don't confirm whether this pack changes the mod's maximum laser length setting. Test it in-game before you plan a big build around a specific length.

Laser Bridges & Doors is built around one idea: a laser source block that projects a futuristic laser structure when you power it with redstone. Depending on the setup, that structure acts as a bridge, a door or a fence. There's no energy system or fluid handling to learn here. Redstone is what switches everything on.^[1]

Powering a laser source

A Laser Source does nothing on its own. The laser only forms once the block gets a redstone signal. That means you can use any normal redstone input to control it, such as a lever, a button, a pressure plate or a whole circuit.^[1]

The fun part is that the laser's length follows the signal strength, and it updates as the signal changes. A strong signal gives you a long beam and a weaker one gives a shorter beam. If you vary the signal, for example by adding distance along a redstone line or using a comparator setup, the bridge grows and shrinks on the fly.^[1]

The mod also has full block laser sources for building more complicated redstone contraptions, so lasers can become part of bigger builds instead of just simple on/off doors.^[1]

Maximum length and blocked paths

How far a fully powered laser reaches is set by the mod's max_length config option. Every partial length at lower signal strengths is calculated from that value. In the mod's own defaults, max_length is 15. The value this pack uses isn't confirmed, because the pack's config file for this mod wasn't available.^[1]

A second option, blocks_cut_through_by_lasers, holds a list of blocks that lasers are allowed to replace. Blocks on that list won't stop a beam. The mod's config can be changed in-game or in its JSON file.^[1]

Unverified The exact contents of the blocks_cut_through_by_lasers list in All the Mods 10 7.3, and whether the pack changed max_length, could not be confirmed. Test beam length and pass-through behaviour in your own world before you plan a build around specific numbers.

Coloring your lasers

You can color a laser source by clicking it with a dye in your hand. A dispenser can also apply dye to it, so you can recolor lasers automatically as part of a redstone build.^[1]

Getting and converting laser sources

All the Mods 10 7.3 changed the mod's own recipe for the Laser Source, and it adds a second KubeJS recipe that makes the same block. The KubeJS version accepts any glass from the glass blocks tag. Both recipes are shown below with their exact in-pack ingredients, so ignore older crafting guides for this block.^[3]

The Laser Fence Source is not crafted from scratch. You convert a regular Laser Source into it with a shapeless recipe, and you can convert it back the same way. You never lose a laser source by picking the wrong variant.^[1][3]

There isn't a long tier ladder here. The mod adds two blocks, the Laser Source and the Laser Fence Source, and your progression starts with crafting a Laser Source.^[3]

The Laser Source is your entry point. This pack changed the mod's own shaped recipe for it, so check the recipe below for what the block costs in this pack.^[3]

Once you have a Laser Source, you can turn it into a Laser Fence Source with a shapeless recipe. You can also turn it back the same way, so you never lose materials by picking the wrong one.^[3]

Laser Bridges & Doors has been part of All the Mods 10 for a long time. It was first included in All the Mods 10 2.2 or earlier, and in All the Mods 10 7.3 you're running version 5.3, shipped as the file laserbridges-1.21.1-neoforge-5.3.jar.^[2]

Updates across pack releases

• All the Mods 10 2.39: updated from 1.21.1-1-neoforge to 5.^[4]
• All the Mods 10 4.15: updated from 5 to 5.3.^[5]
• All the Mods 10 6.1: the changelog lists an update from 5.3 to 5.3, so the version number stayed the same.^[6]
• All the Mods 10 6.2: the changelog again lists an update from 5.3 to 5.3, with no change to the version number.^[7]
• All the Mods 10 7.3: still ships version 5.3.^[2]

Since 4.15 the version number hasn't changed. The two 5.3 to 5.3 entries in 6.1 and 6.2 may just mean the file was re-uploaded or repackaged under the same version.^[5][6][7]

Unverified The mod's own changelogs aren't available here, so it's unverified what actually changed in each update: new features, bug fixes, or changes to recipes and mechanics. It's also unverified whether the 5.3 to 5.3 updates in 6.1 and 6.2 changed anything in the mod itself.
