Unity Collider - OnTriggerEnter

Question

我与Unity的begginer，我开始了一个小项目，我使用架构for inventtrory。

我试图在我的游戏中建立一个安全区域。我的安全区有一个触发器“on”的对撞机。

如果我的玩家进入安全区域，我只想发送消息。 我的问题是当玩家进入时，我不能得到玩家的名字，它给我“_TriggerHandler”作为价值而不是我的玩家。

代码永远不会进入“如果”，我得到控制台中的第一个调试日志，但没有别的。 （p为空）（other = _TriggerHandler）

不能理解为什么其他= _TriggerHandler。

using Devdog.General; 
using System.Collections; 
using System.Collections.Generic; 
using UnityEngine; 

public class SafeZone : MonoBehaviour { 

    protected vp_FPPlayerEventHandler m_Player = null; 
    protected bool safe; 

    // Use this for initialization 
    void Start() 
    { 
     m_Player = GameObject.Find("Gringan").GetComponent<vp_FPPlayerEventHandler>(); 
    } 

    // Update is called once per frame 
    void Update() 
    { 

    } 

    /// <summary> 
    /// registers this component with the event handler (if any) 
    /// </summary> 
    protected virtual void OnEnable() 
    { 
     if (m_Player != null) 
      m_Player.Register(this); 
    } 

    /// <summary> 
    /// unregisters this component from the event handler (if any) 
    /// </summary> 
    protected virtual void OnDisable() 
    { 
     if (m_Player != null) 
      m_Player.Unregister(this); 
    } 

    void OnTriggerEnter(Collider other) 
    { 
     var p = other.GetComponent<Player>(); // Player is in Devdog.General; 
     print("Collision detected with trigger object " + other.name + " p= " + p); 
     if (p != null) 
     { 
      print("Collision detected with trigger object PLAYER " + other.name); 
      safe = true; 
      m_Player.PlayerIsSafe.Send(safe); 
     } 
    } 

    void OnTriggerStay(Collider other) 
    { 
     var p = other.GetComponent<Player>(); // Player is in Devdog.General; 
     if (p != null) 
     { 
      print("Still colliding with trigger object PLAYER " + other.name); 
      safe = true; 
      m_Player.PlayerIsSafe.Send(safe); 
     } 
    } 

    void OnTriggerExit(Collider other) 
    { 
     var p = other.GetComponent<Player>(); // Player is in Devdog.General; 
     if (p != null) 
     { 
      print(gameObject.name + " and trigger object PLAYER " + other.name + " are no longer colliding"); 
      safe = false; 
      m_Player.PlayerIsSafe.Send(safe); 
     } 
    } 
} 

控制台消息：

- >

碰撞触发对象_TriggerHandler类P检测= UnityEngine.MonoBehaviour：打印（对象） 安全区域：OnTriggerEnter（撞机）（在资产/我的资产/脚本/ SafeZone.cs：44）

我想知道是否有人知道会发生什么情况？

感谢您的帮助。

好吧，我做到了:)，不得不使用other.transform.parent.GetComponent（）;就像说Nika Kasradze，然后我必须在做任何事情之前测试玩家是否为空:)

感谢您的帮助！
