HELM

Huge pathfinding overhaul built from the ground up, plus a brand new waypoint system.

New: Waypoints

• /helm wp and /helm waypoints — the same full command tree under two names:
  • list [tag] — show saved waypoints, optionally filtered by tag
  • save <name> [tag] — save your current position as a named waypoint
  • delete <name> [tag] — remove a waypoint by name
  • goto <name> [tag] — pathfind straight to a waypoint
• Tag autocomplete for home, base, death, bed, spawn, user; name autocomplete from your saved waypoints
• Automatic death waypoints — when you die, HELM saves where you died and posts a clickable chat line: oof you died [click here] to walk back to where you died :D (click runs /helm wp goto death)
• Automatic bed waypoints — setting your respawn saves the bed position (resolves the bed head, dedupes repeats)
• Both auto behaviors can be toggled with the bedwaypoints and deathwaypoints settings (on by default)
• Waypoint storage with per-tag files, time-ordered indexes, atomic writes, nearest-waypoint and by-name lookups, per-world folders under mods/helm/waypoints/

New storage layout

• All HELM data now lives in .minecraft/mods/helm/ instead of scattered in mods/
• Your macros folder moved to mods/helm/macros/ and settings to mods/helm/settings.properties — existing files are migrated automatically on first launch

Pathfinding: Custom high-performance movement system

• Full movement state machine (prepping, waiting, running, success, unreachable, failed) with a prepared phase that pre-breaks blocks, pauses for falling blocks, auto-jumps out of water and mines free when stuck in a wall
• Snaps to the closest path position when you drift (with mid-air guards), trims long path history, and skips descend-into-ascend pairs for smooth downhill runs
• Ascend movements place their own support block with sneak-place and back off if it keeps failing
• Auto-disable of Minecraft's auto-jump while pathing

New movements

• True diagonal movement with sprint pricing, edge-around corner logic, and customized soul sand, magma, and frost walker cost modifiers
• Gated diagonal ascend and diagonal descend (diagonalascend / diagonaldescend settings, off by default)
• Edge sneak along cliff ledges
• Water bucket clutch (MLG) for falls up to 20 blocks, falls may land in water
• Doors and fence gates are opened live, closed behind you, and iron doors are respected

Other improvements

• Explore command walks outward ring by ring to the closest never-cached chunks
• Ladders and vines are climbed instead of tunnelling past them
• Swimming rewritten with exact water physics, no more surface oscillation
• Splices planned path segments onto the live path, static cutoff past 30 movements
• Doors, swing and reach fixes across the board
