World configuration management

[Sceat]

The world is shared between the dapp and the server. It would be more intuitive to have a properly defined config which is not mutated at runtime.

since it often changes, it's complex to not have outdated or wrong code. Avoiding mutations is the best way to remove side effects (if world_env is modified elsewhere and we don't know about it, it can cause havoc in the app)

Improved isolation:

new World({ seed: '', ...config }).generate_chunk()

Ex from the server, I use a single object.

import { WorldEnv, Heightmap } from '@aresrpg/aresrpg-world'

import { SCHEMATICS_FILES } from './schematics_files.js'
import { LANDSCAPE, SCHEMATICS_BLOCKS_MAPPING } from './world_settings.js'

const world_settings = {
  seed: 'aresrpg',
  sea_level: 76,
  patch_view: {
    near: 4,
  },
  biomes: LANDSCAPE,
  schematics: {
    blocks_mapping: SCHEMATICS_BLOCKS_MAPPING,
    files: SCHEMATICS_FILES,
  },
  boards: {
    radius: 20,
    thickness: 3,
  },
  heightmap: {
    spread: 0.42,
    harmonics: 6,
  },
  chunks: {
    size: { xz: 64, y: 64 },
    altitude: { min: -1, max: 400 },
  },
}

WorldEnv.current.seaLevel = world_settings.sea_level
WorldEnv.current.patchViewCount.near = world_settings.patch_view.near // chunks view below ground surface

// EXTERNAL CONFIGS/RESOURCES
WorldEnv.current.biomes.rawConf = world_settings.biomes
// populate inventory with schematics
WorldEnv.current.schematics.globalBlocksMapping =
  world_settings.schematics.blocks_mapping
// @ts-ignore
WorldEnv.current.schematics.filesIndex = world_settings.schematics.files

// BOARDS
WorldEnv.current.boardSettings.boardRadius = world_settings.boards.radius
WorldEnv.current.boardSettings.boardThickness = world_settings.boards.thickness

Heightmap.instance.heightmap.params.spreading = world_settings.heightmap.spread
Heightmap.instance.heightmap.sampling.harmonicsCount =
  world_settings.heightmap.harmonics

// chunks gen
WorldEnv.current.chunks.range.bottomId = Math.floor(
  world_settings.chunks.altitude.min / world_settings.chunks.size.y,
)
WorldEnv.current.chunks.range.topId = Math.floor(
  world_settings.chunks.altitude.max / world_settings.chunks.size.y,
)

world_env.seeds.main = world_settings.seed
