Question

我目前有一些代码可以通过数组在屏幕上放置一些按钮，然后在检查器中分配纹理。问题是我不知道怎么做，例如按钮1退出游戏，按钮2进入下一级别，按钮3加载图像。有人可以向我解释一下我需要做些什么来使单个按钮在点击时做不同的事情？（第二个数组用于屏幕右侧的按钮）

这就是我现在的代码：

using UnityEngine;
using System.Collections;

public class UI : MonoBehaviour
{
    public Texture2D[] parts;
    public Texture2D[] extra;
        int buttonHeight, buttonWidth;
    int x, y;
    int width, height;

    void OnGUI ()
    {
        for (int i = 0; i < parts.Length; ++i) 
        {
            if (GUI.Button (new Rect (x - 35, i * (height + 97), width + 300, height + 90), parts [i]))
            Debug.Log ("Clicked button " + i);
            //if (GUI.Button (new Rect (0, i * (buttonHeight + 20), buttonWidth + 100, buttonHeight + 100), textures [i]))
       }
       for (int x = 0; x < extra.Length; ++x) 
       {
           if (GUI.Button (new Rect (x + 800, x * (height + 140), width + 300, height + 120), extra [x]))

           Debug.Log ("Clicked button " + x);
           if (extra [0] && Input.GetButtonDown ("Jump")) 
           {
               Application.CaptureScreenshot ("Screenshot.png");
               Debug.Log ("Screen captured");
           }
       }
    }
}

这样的事情会起作用：

using UnityEngine;
using System.Collections;

public class UI : MonoBehaviour {

public Texture2D[] parts;
public Texture2D[] extra;
public string[] actions;
int buttonHeight, buttonWidth;
int x, y;
int width, height;

void OnGUI ()
{
    for (int i = 0; i < parts.Length; ++i) 
    {
        if (GUI.Button (new Rect (x - 35, i * (height + 97), width + 300, height + 90), parts [i]))
            Execute(actions[i]);
        //if (GUI.Button (new Rect (0, i * (buttonHeight + 20), buttonWidth + 100, buttonHeight + 100), textures [i]))
    }
    for (int x = 0; x < extra.Length; ++x) 
    {
        if (GUI.Button (new Rect (x + 800, x * (height + 140), width + 300, height + 120), extra [x]))

            Debug.Log ("Clicked button " + x);
        if (extra [0] && Input.GetButtonDown ("Jump")) 
        {
            Application.CaptureScreenshot ("Screenshot.png");
            Debug.Log ("Screen captured");
        }
    }
}

void Execute(string action) {
    switch (action) {
    case "exit":
        Application.Quit();
        break;
    case "next":
        // Load next level..
        Debug.Log("next");
        break;
    }
}

}

如何让我的按钮在Unity中用C＃做不同的事情？
