Mob Hop

MobHop 1.0.1

Added

• Animals and pets hop too when they are being led. A cow following the wheat in your hand, a wolf or cat following its owner, and a young animal following its parent now hop the fence or the gap between them and where they are led, after standing at it for about half a second. A mob that only wanders does not hop: animals stay in their pens unless you lead them out. Set onlyWhenChasing to true to get the 1.0.0 behavior back (only mobs with an attack target hop).
• New mod icon.

Changed

• Mobs now land right behind what they hop. The hop is steered all the way and ends in the middle of the block behind the fence. In 1.0.0 a mob flew on and came down one or two blocks further, on ground the mod had not checked for lava, a drop or a low ceiling.
• Hops are slower and look like jumps: a fence is crossed at roughly 4.5 blocks a second instead of up to 7.5. Where a hop needs more time (an obstacle a whole block deep, two fences in a row), the mob jumps higher instead of faster.
• Two fences standing one right behind the other are hopped in one jump. A mob never lands on a fence, wall or pane now. Three in a row still stop a mob.
• A mob that stopped a little short of a fence or a gap now hops it from where it stands. In 1.0.0 it had to be pressed against the fence or standing on the very edge.
• A mob standing off-center is handled correctly: it hops a fence that only its side would touch, and it does not jump into a wall that stands beside the fence.
• Mobs turn to face the way they hop.
• Lower minimum Fabric versions: 1.0.1 asks only for the oldest build of each Minecraft line it works with. On 1.20.1, for example, 1.0.0 asked for Fabric Loader 0.16.10 and Fabric API 0.92.7; now it's 0.14.21 and 0.83.0.
• Fabric 26.1.2 now asks for Fabric Loader 0.19.5 or newer: Architectury API 20.1.14 crashes the game at startup on older loaders even though it claims to accept 0.18.5.
• Forge now starts at each line's first recommended build (43.1.0, 47.1.0, 52.1.0, 61.1.0). 1.0.0 accepted every Forge build of a line, betas included.

Fixed

• A very low clearanceMargin no longer makes fences impossible (mobs jump them a little higher instead), and forwardBoost no longer pushes a mob past its landing.
• Hops no longer end on top of the second of two fences in a row.
• Forge and NeoForge 1.21.11: the log no longer shows "Couldn't load mod/mobhop pack metadata" every time a world is loaded (the tags loaded before as well).
• A NaN written by hand into a decimal setting of config/mobhop.json (maxHopHeight, minObstacleHeight, clearanceMargin, forwardBoost, maxGapWidth, obstacleReach, maxDropHeight) no longer wipes the config. Before, the file was left cut short, then moved to mobhop.json.bak and every setting was reset. Such a value now falls back to that setting's default.

Unchanged

• The config file and the datapack tags keep their format; no key was added or removed.
• Same Minecraft versions and loaders as 1.0.0: nothing added, nothing removed.

Compatibility

• Runs on the server (the integrated server in single player). In multiplayer, clients do not need it.
• Fabric needs Fabric API and Architectury API. NeoForge needs Architectury API. Forge needs nothing else. There are no Forge files for 26.x.

Architectury API is needed on Fabric and NeoForge only.
