Unity 中实现一个碰撞体（Collider）管理类监测多个物体触发事件

通过脚本所挂载的物体名称来添加不同触发事件。

using UnityEngine;

/// <summary>
/// 碰撞体物体管理类

public class ColliderManager_01 : MonoBehaviour
{
    private delegate void TriggerEvent(Collider other);
    private TriggerEvent enterEvent, stayEvent, exitEvent;

    // Start is called before the first frame update
    private void Awake()

        stayEvent = null;
        exitEvent = null;
        switch (transform.name)
        {

                enterEvent = NoseBoxColliderEnter;
                stayEvent = NoseBoxColliderStay;
                exitEvent = NoseBoxColliderExit;
                break;

                break;
            default:
                break;
        }
    }
