Trapdoor Ladder
by UwU_Snek
Trapdoor Ladder lets a ladder and a trapdoor share one block, so a single placement gives both functions.
What it does
A ladder and a trapdoor can be merged into one block, which takes the space of a single trapdoor while still offering the climbing surface of a ladder. The block is craftable and breakable in ordinary survival play, and it is tagged with the same properties as vanilla trapdoors so other mods and datapacks treat it alike.
The mod is published for Fabric only, for 1.21.7 and 1.21.8, with 1.0.0 for 1.21.8 as the latest file. It is licensed under the GNU General Public License v3.0 or later and is open source. Only the Fabric loader is supported, and it runs on client and server, so the server and every player need it.
Redstone interactions with the Wind Charge are fully supported, so the merged block responds to the same redstone and wind charge inputs as a standard trapdoor.
Key features
Merged ladder and trapdoor
A ladder and a trapdoor combine into one block, so a wall can hold a climbable hatch without extra placement steps.
Craftable and breakable
The block can be crafted and broken with normal survival tools, so it fits into regular progression.
Vanilla trapdoor properties
The blocks carry the same tags as vanilla trapdoors, which keeps them compatible with other content that checks those tags.
Wind Charge interactions
Redstone and Wind Charge inputs work on the merged block, matching the behavior of a trapdoor.

Use cases
Compact hatches
A single block serves as both a trapdoor and a ladder, which saves space in tight builds like treehouses and mineshaft-style rooms.
Who it’s for: Builders who want a climbable hatch in one block, and server owners running Fabric for 1.21.7 or 1.21.8 who need the mod on both sides.
