Unity API【Physics.OverlapSphere】及其技巧

1 API介绍

2 函数声明

3 用法解析

4 技巧1：获取一定距离内最近的一个敌人单位

//代码
public Transform  OverlapSphereCube; 
public float SearchRadius;
//假设 SearchRadius表示的相交球的检测半径值，大到足够覆盖到Cube4

void Start()
{
    SearchNearUnits();
}

public void SearchNearUnits()
{
  Collider[] colliders = Physics.OverlapSphere(OverlapSphereCube.position, SearchRadius，1 << LayerMask.NameToLayer("Enemys"));

  if（colliders.Length <= 0） return ;

  for (int i = 0; i < colliders.Length; i++)
      print(colliders[i].gameObject.name);
}

5 技巧2：实现AOE（范围）伤害，例如手雷爆炸的范围伤害
