Preview nature and weather

Preview before applying

import { createNatureState,previewLightning,applyLightning,isEnvironmentTurnScheduled } from "@johnmorrisdotca/houseki/nature";
const state=createNatureState({width:4,height:4,seed:"weather-docs"});
const preview=previewLightning(state,{columns:[0]});
const result=applyLightning(state,{columns:[0]});
console.log(preview.columns,result.accepted,isEnvironmentTurnScheduled(2,{kind:"authored",turns:[2,4]}));

[ 0 ] true true

Nature owns the passable-cell mask, stone/obstacle ids and random state. Obstacles collide and block attraction, but cannot attract or move. Magnetic previews, power-drop previews and weather previews retain the input. Apply the corresponding transition to commit its state and events. A power-drop request names a pivot id contained in its piece; arbitrary overlapping cells are invalid.

Use the native campaigns

import { shizenLevelManifest,arashiLevelManifest,createShizenLevel } from "@johnmorrisdotca/houseki/colour-chains";
console.log(shizenLevelManifest.length,arashiLevelManifest.length,createShizenLevel(1).settings.nature);

128 128 true

Shizen and Arashi are separate Colour Chains campaigns. Keep their nature/weather settings and magnetic queue. powerDropPreview can be null when it does not apply; its finalCells are the lock positions, while settledCells include the committed drop’s gravity result.
