meteors

Meteors fall within 100 blocks of a random Overworld player. Each server tick runs the meteor rolls once per dimension; only the Overworld's rolls drop meteors.

Field	Meaning and default	Range
`enable_showers`	Enables meteor showers; requires `enable_strikes`; default `true`.
`enable_special`	Falling-meteor impacts form one of 11 special meteorite structures with chance 11/300; default `true`.
`enable_strikes`	Enables meteor strikes; `false` also removes falling meteors; default `true`.
`enable_tails`	Meteor flame trails and impact rubble and particles; default `true`.
`shower_chance`	During a shower, chance 1 in this value per Overworld tick to drop a meteor; default `18000`.	[1, \texttt{i32::MAX}]
`shower_duration`	Shower length: random from 0.75 to 1 times this value, counted down once per dimension each tick; default `36000`.	[0, \texttt{i32::MAX}]
`strike_chance`	Outside a shower, chance 1 in this value per Overworld tick to drop a meteor. Each dimension's tick also starts a shower with chance 1 in 100 × this value. Default `360000`.	[1, 21474836]

Example: data/hbm/hbm/world_config/meteors.json.

loot

Field	Meaning and default	Range
`amount_factor`	Multiplier f for `hbm:config_scaled` loot values v: \max(1, \lfloor v f \rfloor); default `1`.	[0, 1000]
