Unity 與 委託(1)

之前公司寫UNITY是用 UNITY SCRIPT，專案越寫越大，總感覺有些不夠嚴謹。 下次專案預定改成C# C#有一個很好用的機制 delegate 就當作學習心得記錄下來 主程式 拖到場景的物件中

using UnityEngine;
using System.Collections;


public class test : MonoBehaviour {

 public delegate string ProcessDelegate(string s1, string s2);
 ProcessDelegate pd;

 // Use this for initialization
 void Start () {

  pd = new ProcessDelegate(new delegateEx1().Process);
            
 }
 
 // Update is called once per frame
 void Update () 
 {
  Debug.Log(pd("Hello", "World")); 
 }
}

code delegateEx1 如下

using UnityEngine;
using System.Collections;

public class delegateEx1  {

 public string Process(string s1,string s2)
 {
  return s1 + s2;
 }
}

結果會在 Console視窗中不斷顯示 HelloWorld 另一種調用的方式

using UnityEngine;
using System.Collections;


public class test : MonoBehaviour {
 public delegate string ProcessDelegate(string s1, string s2);

 ProcessDelegate pd;

 // Use this for initialization
 void Start () {

  //pd = new ProcessDelegate(new delegateEx1().Process);
  ReceiveDelegateArgsFunc(new ProcessDelegate(new delegateEx1().Process));
            
 }
 
 // Update is called once per frame
 void Update () 
 {
  //Debug.Log(pd("Hello", "World")); 
 }

 public void ReceiveDelegateArgsFunc(ProcessDelegate func)
 {
  string str = func("good","test");   
  Debug.Log(str);
 }

}

結果會在 Console視窗中顯示 goodtest
