Horse Powered 3.9.1

Hotfix port of the 1.21.1 branch's 2.5.1 release into 26.1.

New Content

• Wooden Hopper art: new textures and Blockbench-authored models donated by emmen. Top, inside, outside, and new bottom textures, plus updated item art.
• Flint and Tinder art: donated by ArtpokeBR.

Gameplay Changes

• Flint and Tinder hold-to-use: must now be held like firing a bow before it lights anything. The bow-style animation plays and smoke drifts from the targeted block while the player holds right-click. After about two seconds the block is ignited, or campfires, candles, and TNT light directly. Releasing early cancels with no use spent. Durability lowered from 16 to 8 to compensate for the easier renewable supply via the Drying Rack's dead-bush recipe.

Bug Fixes

• Hand Grindstone hitbox shrunk to match the model: the old selection box was a single 14-tall cube that visually covered the side items and made them hard to click. Selection and collision now follow the visible geometry (a flat base plus the central stem). Turning the wheel only fires when right-clicking the stem itself, so clicking on a base side reliably extracts that side's slot even while the grindstone has work to do. Pickup quadrants on the base top are also enlarged from the old narrow strips to the full base quadrant.
• Horse Power Generator stone-tier requirement and charge persistence: the generator now sits in both the pickaxe and needs_stone_tool tags. Stored FE is attached to the dropped item as a BLOCK_ENTITY_DATA data component, and placing the item back restores the buffer. The horse, if any, is still released as a live entity with a lead, so charge moves with the block while the worker is freed.

Suggestion Implementation

• Path surface affects worker speed: every horse-powered block (Grindstone, Chopper, Press, Generator) now samples the 24 floor blocks under its circular path and averages a per-block speed multiplier. Faster paths produce recipes faster; slower paths slow them down. Defaults: dirt, grass, coarse dirt, and rooted dirt run at 0.5x; dirt path at 1.0x; packed ice at 2.0x. Anything not listed defaults to 1.0x. Multipliers and defaults are configurable in config/horsepowered-common.toml under [horse_path] via pathSpeedEntries and pathSpeedDefault.
• Working area now tolerates a few obstructions: chests, hoppers, gears, and other non-replaceable blocks can sit inside the 7x7 ring without invalidating the area. Default tolerance is 2 blocks, raise or lower it via [horse_path] pathObstructionTolerance (range 0 to 40). Levers remain always-allowed, and the floor sturdiness check is unchanged.

Documentation (GuideMe)

• New Horse Path & Speed page covering working area, obstruction tolerance, the speed multiplier defaults, and the config snippets for customizing both.
• New Flint and Tinder page covering the hold-to-use behavior, smoke feedback, retargeting during use, and the lowered durability.
• Each horse-powered machine page (Grindstone, Chopper, Press, Generator) now links to the Horse Path & Speed page, and the index Tips section calls out the new path mechanic.
• Generator guide updated to note that breaking and replacing the block preserves stored charge.
