About this project
What does Flexible Marker CRE add?
Flexible Marker CRE (Cleanroom Edition)
This mod requires Cleanroom Loader.
A Cleanroom port of Flexible Marker.
Description
Flexible Marker
A marker that lets you configure a machine's working area by setting the distances upward, downward, left, right, and forward independently. You can adjust the area through its GUI after placement, without having to place multiple markers far apart.
Useful for defining areas around structures or limiting mining and terrain clearing to specific heights.
Chunk Marker
A marker that lets you configure a machine's working area in chunks. The horizontal area aligns with chunk boundaries, and you can adjust the minimum and maximum Y coordinates through its GUI.
Useful for chunk-aligned mining and clearing larger areas.
Requirements
- Cleanroom Loader 0.7.14 or later
- ModularUI 3.1.6 or later
Changes
- Rewrote the GUIs using ModularUI.
- Rewrote the Scala code in Java, removing the dependency on a Scala runtime provider.
- Migrated to Java 25 and Cleanroom Loader.
