State Synchronization

Ensure consistent game state across all connected players.

Snapshot Interpolation

class SnapshotBuffer {
  constructor(size = 3, delay = 100) {
    this.buffer = [];
    this.size = size;
    this.delay = delay;
  }

  add(snapshot) {
    this.buffer.push({
      time: snapshot.serverTime,
      entities: new Map(snapshot.entities)
    });
    while (this.buffer.length > this.size) {
      this.buffer.shift();
    }
  }

  interpolate(renderTime) {
    const targetTime = renderTime - this.delay;
    const [before, after] = this.findBrackets(targetTime);

    if (!before || !after) return this.extrapolate();

    const t = (targetTime - before.time) / (after. - before.);
     .(before, after, t);
  }

  () {
     result =  ();
     ( [id, a]  before.) {
       b = after..(id);
       (b) {
        result.(id, {
          : a. + (b. - a.) * t,
          : a. + (b. - a.) * t,
          : a. + (b. - a.) * t
        });
      }
    }
     result;
  }
