クラス: PairManager

定義: pair-manager.ts:59

Manages collision pairs across frames.

Remarks

Tracks which bodies are colliding and for how long, enabling collision lifecycle events (start, update, end). This is useful for game logic like damage on collision start or triggers.

Automatically cleans up old inactive pairs to prevent memory leaks.

例

Using collision events

const pairManager = world.getPairManager();

world.step(dt);

const events = pairManager.getActivePairs();
events.forEach(pair => {
  if (pair.frameCreated === world.currentFrame) {
    console.log('Collision started!');
  }
});
