About this Mod

     

Diagonal Walls completes the Diagonal Blocks family, allowing walls to connect diagonally for more natural shapes and more freedom in your builds. 🧱 Castles, ruins, and city walls can now be designed without being locked to rigid angles.

Please note that for technical reasons, installing this mod removes vertical wall connections. Walls will no longer connect upwards and will show gaps when stacked, similar to Minecraft 1.15.2 and earlier. This behavior is not a bug, and restoring vertical connections is not technically feasible and is therefore not planned.

Blocks added by other mods are supported dynamically whenever possible, and any unintended behavior can be controlled using the diagonalwalls:non_diagonal_walls block tag. ⚙️ It also works seamlessly with most resource packs without extra setup.

Part of the Diagonal Blocks family, alongside Diagonal Fences and Diagonal Windows, expanding diagonal building in multiple directions. ✨

⏩ INSTALLATION REQUIRED ON CLIENT & REQUIRED ON SERVER

⏩ REQUIRES PUZZLES LIB TO BE INSTALLED (FABRIC & NEOFORGE)

⏩ REQUIRES FABRIC API TO BE INSTALLED (FABRIC)

⏩ REQUIRES FORGE CONFIG API PORT TO BE INSTALLED (FABRIC)

If available for a mod, configuration is possible directly from in-game using the mod menu (requires Mod Menu by Prospector to be installed on Fabric).

For manual configuration using an external text editor all files are found at .minecraft/config, named as MOD_ID-client.toml, MOD_ID-common.toml, or MOD_ID-server.toml, depending on the type of config. Not all types might exist for a mod, if any at all.

🌟 Thanks a lot to XFactHD for contributing the diagonal model transformation code and helping out during development in general!

Frequently Asked Questions

Diagonal Walls server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.3). You can switch loaders with one click in the panel.

Is Diagonal Walls compatible with fabric and forge and neoforge?

Diagonal Walls officially supports fabric, forge, neoforge for Minecraft 26.3, 26.2, 26.1.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Diagonal Walls – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Diagonal Walls consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
