ReelSetBuilder

Every method returns this so you can chain.

Required

Method
`.reels(n)`	Number of columns.
`.visibleSymbols(n)`	Rows visible at rest.
`.symbolSize(w, h)`	Per-symbol dimensions in px.
`.symbols((r) => { r.register(...) })`	At least one symbol id.
`.ticker(pixiTicker)`	Drives frame updates.

Missing any of these throws at .build() time with a human-readable list of problems.

Optional

Method	Default
`.symbolGap(x, y)`	`{ x: 0, y: 0 }`
`.bufferSymbols(n)`	`1`
`.weights({ id: n })`	`10` for each registered symbol
`.speed(name, profile)`	`SpeedPresets.NORMAL` under `'normal'`
`.initialSpeed(name)`	`'normal'`
`.offsetConfig(config)`	`{ mode: 'none' }`
`.spinningMode(mode)`	`new StandardMode()`
`.frameMiddleware(mw)`	(none)
`.phases((f) => { f.register(...) })`	built-in START/SPIN/STOP/ANTICIPATION
`.initialFrame(grid)`	random

.build()

Validates every required field, instantiates every subsystem, returns a ReelSet.

Example

import { ReelSetBuilder, SpriteSymbol, SpeedPresets } from 'pixi-reels';

const reelSet = new ReelSetBuilder()
  .reels(5)
  .visibleSymbols(3)
  .symbolSize(140, 140)
  .symbolGap(4, 4)
  .symbols((r) => {
    r.register('cherry', SpriteSymbol, { textures: { cherry: cherryTex } });
  })
  .weights({ cherry: 40 })
  .speed('turbo', SpeedPresets.TURBO)
  .ticker(app.ticker)
  .build();
