优化 if else 和 Switch Case
z
大量的if else 和 Switch Case会造成代码冗余且消耗性能，可以借用如下方法优化

1. 使用字典进行优化

   • 方法优化：

   //注册字典，通过Action作为值，然后进行回调
   private Dictionary<int, Action<CharacterEntity>> animationActions =new Dictionary<int, Action<CharacterEntity>>(){{ 0, (character) => character.animator.SetTurnUp() },{ 1, (character) => character.animator.SetTurnDown() },{ 2, (character) => character.animator.SetTurnRight() },{ 3, (character) => character.animator.SetTurnLeft() }};/****************调用方法****************/
   //通过对字典判空
   //传参执行回调
   private void UpdatePlayerAnimation(CharacterEntity character, int id){if (animationActions.TryGetValue(id, out var action)){action(character);}}
   

2. 使用数组进行优化：

   • 优化坐标：

   //创建坐标数组
   private Vector3[] _positionOffsets = new Vector3[]{new Vector3(0, 1f, 0),new Vector3(0, -0.2f, 0),new Vector3(-0.7f, 0, 0),new Vector3(0.7f, 0, 0)};//直接通过id调用即可
   transform.position = pos + _positionOffsets[id];
