Babylon.js 汉诺塔

核心代码

监听鼠标选中事件，记录圆盘对象和初始位置，方便在操作错误的情况下重置圆盘位置

scene.onPointerDown = function (evt, pickResult) {
   
  if (
    pickResult.pickedMesh &&
    pickResult.pickedMesh.name.startsWith('disk')
  ) {
   
    const newPositionX = pickResult.pickedMesh.position.x
    const towerIndex = towers.findIndex(
      (tower) => Math.abs(tower.tower.position.x - newPositionX) < 1
    )
    if (towerIndex != -1) {
   
      const stack = diskStacks[towerInd
