v0.1.4: Copy Entities, Infinite Reach Fixes, and Better Paper Editing

Axion v0.1.4 is a smaller follow-up release focused on reliability. It finishes the biggest missing pieces of Copy Entities, cleans up awkward infinite reach edge cases, improves how Paper-backed edits behave on servers with anti-xray enabled, and includes a small symmetry polish for mixed half-block anchor positions.

Highlights

• Finished the biggest missing Copy Entities cases, especially mounted and riding entity handling
• Fixed several infinite reach edge cases, especially around vanilla reach boundary behavior
• Improved Paper-backed clone, move, stack, smear, erase, and undo behavior around anti-xray-obfuscated underground blocks
• Smoothed out one awkward rotational symmetry case when anchors land on mixed .0 / .5 positions

Copy Entities

Copy Entities already existed before v0.1.4, but this release finishes some of the most important missing cases.

• Move and Clone are more reliable for real build scenes instead of only simple standalone entities
• Stack can now repeat entities along with the stacked build when Copy Entities is enabled
• Erase can now remove entities too when Copy Entities is enabled
• Clone capture now happens at confirm time, which works better for live contraptions and moving setups

This also includes better handling for mounted entities.

• Boats with riders now move correctly
• Boats with riders now clone correctly
• Stacked copies can now preserve those rider chains too
• Undo/redo tracks these entity-aware operations more reliably in both singleplayer and Paper-backed multiplayer

Symmetry

This release also includes a small quality-of-life symmetry fix.

• Mixed horizontal anchor positions like .0 / .5 now behave more naturally for the common 4-way cardinal rotational layout
• In practice, anchors like .0 .0 .5 should now place much closer to the expected ring pattern instead of producing an awkward offset result

Infinite Reach

Infinite reach got a cleanup pass aimed at making it feel less surprising.

• Axion now prefers the normal vanilla crosshair target first when you are already close enough to interact normally
• Borderline infinite-reach break cases are more stable and less likely to hit an extra block behind the intended target
• Far targeting is now more consistent when you are right on the edge of vanilla reach distance

Paper Anti-Xray Fixes

On Paper servers with anti-xray enabled, underground edits could sometimes end up using the client’s obfuscated block view instead of the server’s real source blocks.

v0.1.4 improves that by pushing more of these edit paths through server-authoritative block reads instead of trusting what the client can currently see. In practice, underground terrain edits and undo on Paper should behave much more like you expect, even with anti-xray enabled.

That improvement now applies more broadly across normal Paper-backed edit flow, including:

• Clone
• Move
• Stack
• Smear
• Erase
• Undo

Server / Paper Notes

If you use Axion on a server, update both the Fabric client mod and the Paper plugin together for this release.

v0.1.4 includes protocol and server-backed edit changes for:

• entity-aware clone / move / stack / erase behavior
• infinite reach interaction handling
• Paper-authoritative underground edit behavior for the new anti-xray fix
