Unity的sendmessage用法

剛學完sendmessage用法，自己也嘗試測試了一下，用法如下：

1.在unity2017新建一個場景test

2.在場景中添加一個立方體cube作為主角，另添加一個膠囊體capsule，調整為如圖形狀作為被調用方。

3.給主角添加腳本test.cs

/***

 * 2.添加一個button,用於開啟傳值

 */
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Test : MonoBehaviour {
    public GameObject ReceiveObj;
    void Start()
    {
        ReceiveObj = GameObject.Find ("Capsule");
    }
    void OnGUI()
    {
        if (GUI.Button(new Rect(30,30,50,20),"點擊")) {
            //調用其他腳本的數據
            ReceiveObj.SendMessage("DisPlayContent","I'm Hevin!");
        }
    }
}

4.給capsule添加Receive.CS,用於接受主角的參數傳遞，實現自身旋轉以便更好觀察效果

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Receive : MonoBehaviour {
    private bool IsRotate = false;
    void DisPlayContent (string content) {
        print ("Capsule receive a message" );
        IsRotate = true;
    }
    void Update()
    {
        if (IsRotate) {
            this.transform.Rotate (Vector3.up);
        }
    }
}

5.測試結果，點擊按鈕，膠囊體開始旋轉，sendmessage用法測試完成。
