Simple Chunk Loader

SCL Datapack — Changelog

v1.0.1

Fixed

• Particle display interval — smoke particles were showing roughly once every 3+ minutes instead of every 10 seconds. The reset threshold in validate_loader assumed the timer incremented every tick, but it only increments once per second under the optimized scan schedule. Threshold corrected from 200 to 10.
• Incorrect chunk coordinates on negative X/Z — chat messages showed the wrong chunk number for any loader west of X=0 or north of Z=0, due to integer truncation instead of floor division. Replaced with a new get_chunk_coords function using an offset-before-divide technique that's correct on both sides of the origin.
• Double-deactivation on simultaneous block break — breaking both the Smoker and Redstone Torch in the same tick could call deactivate_loader twice against an already-removed marker entity. validate_loader now guards the second check with if entity @s.
• /function scl:cleanup left stray markers behind — it referenced an scl.detector tag that's never applied anywhere, while never clearing scl.cooldown or scl.new tagged markers that could get orphaned. Now clears the tags that are actually used.

Changed

• Vertical scan range widened from 3 Y-levels (feet ±1) to 5 (feet ±2), so loaders on stairs, scaffolding, or slightly below the player are now detected. Per-player check count rises from 867 to 1,445 every 2 seconds.
• README updated to match actual (optimized) scan behavior — it previously described scanning every tick and particles twice per second, neither of which matched the shipped code.

Added

• New internal function scl:get_chunk_coords — shared floor-division helper used by both activate_loader and deactivate_loader.
• New internal function scl:show_particles — particle logic split out of validate_loader so it only runs once a loader is confirmed still intact.
• New scoreboard objective scl.const holding constants for the coordinate-fix math.

Unchanged

• Core detection logic (Smoker + Redstone Torch on top), forceload add/remove, and item drops on break — all confirmed working correctly.
