Tired of wobbly lines and uneven floors? This client-side mod lets you lock block placement to the X, Y, or Z axis for perfectly straight walls, flat floors, and aligned structures.

AxisLock Example

This mod uses Architectury API and Cloth Config API. If you're using fabric or quilt, you may also need Mod Menu

How to Use:

Activate AxisLock:
Press R (default) to toggle the mod on/off. Or, assign a key in settings to hold for temporary lock.
Select Axis: Press Y (default) to cycle through X, Y, or Z.
Place First Block: This sets the reference point on your chosen axis.
Build Straight: While holding your "place block" key (right-click), axislock will prevent you from placing blocks out of the selected axis coordinate!

Manual Reference Point

AxisLock now allows you to manually set a specific block as the reference point by pressing the assigned key (default: B). Once set, this block will remain as the fixed reference point even after releasing the mouse button, allowing for more precise and consistent locking. To clear or update the reference point, press the reference point key again.

AxisLock Modes

By using the Cycle Mode Key (default: N) you can choose to block block placement, block breaking or both.

Client-side only. Before using this mod on servers check the server rules or ask a moderator. Use at your own risk.

AxisLock is a Fabric (Quilt compatible) and NeoForge mod. There probably won't be a build for Forge until it supports Architectury API in 1.21

It is recommended to use this mod together with accurate block placement or an autoclicker.

AxisLock is now feature complete. This doesn't mean It won't get any more features anymore. But by now I will only update It to fix bugs or when new Minecraft versions come out
