• Unity API学习笔记(2)-GameObject的3种Message消息方法


    官方文档>GameObject

    首先建立测试对象:

    在Father中添加两个脚本(GameObejctTest和Target),分别用来发送Message和接受Message:

    在其它GameObject中添加名为Target的脚本。

     1 using System.Collections;
     2 using System.Collections.Generic;
     3 using UnityEngine;
     4 
     5 public class GameObjectTest : MonoBehaviour
     6 {
     7     // Start is called before the first frame update
     8     public GameObject target;
     9     void Start()
    10     {
    11         // target.SendMessage("Hello");
    12         // target.BroadcastMessage("Hello");
    13         // target.SendMessageUpwards("Hello");
    14     }
    15     void Hello()
    16     {
    17         Debug.Log("In GameObjectTest:" + target.name);
    18     }
    19 }
     1 using System.Collections;
     2 using System.Collections.Generic;
     3 using UnityEngine;
     4 
     5 public class Target : MonoBehaviour
     6 {
     7     public GameObject target;
     8     void Hello()
     9     {
    10         Debug.Log("In Target:" + target.name);
    11     }
    12 }

    分别依次执行:

    •   SendMessage:Calls the method named methodName on every MonoBehaviour in this game object.

          

        也就是当前发送端(Father)所在GameObject下的组件都接收到了Message,但是Son没有接收到,Others没有接收到,Ancestor也没有。

    •   BroadcasMessage:Calls the method named methodName on every MonoBehaviour in this game object or any of its children.

        

        这里可以看到所有的子类包括子类的子类都接收到了Message,要说明一点的是,组件(Component)也是属于GameObject的,所以也接收到了Message。

    •   SendMessageUpwards:Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.

        

        它的父类(Ancestor)接收到了消息,包括它本身。(这里说的是每一个父类都可以接收到Message,意思是如果Ancestor上还有类,那么它们都可以接收到Message)

    通过返回结果不难发现,这三种方法都会调用Message发送给当前作用域内的接收方(也就是谁发送的,就会给自个儿发一份消息)。
