Question

JavaScript => public static var enabled: bool;
C# => public static bool enabled;

Description 描述

Is the GUI enabled?

判断GUI是否启用了。

Set this value to false to disable all GUI interaction. All controls will be draw semi-transparently, and will not respond to user input.

设置为false禁用所用GUI互动，所有控件将被绘制半透明，并且将不响应用户输入。

JavaScript:

// The value tracking whether or not the extended options can be toggled.
	var allOptions : boolean = true;
	// The 2 extended options.
	var extended1 : boolean = true;
	var extended2 : boolean = true;
	function OnGUI () {
		// Make a toggle control that allows the user to edit some extended options.
		allOptions = GUI.Toggle (Rect (0,0,150,20), allOptions, "Edit All Options");
 
		// Assign the value of it to the GUI.enabled - if the checkbox above
		// is disabled, so will these GUI elements be
		GUI.enabled = allOptions;
 
		// These two controls will only be enabled if the button above is on.
		extended1 = GUI.Toggle (Rect (20,20,130,20), extended1, "Extended Option 1");
		extended2 = GUI.Toggle (Rect (20,40,130,20), extended2, "Extended Option 2");
 
		// We're done with the conditional block, so make GUI code be enabled again.
		GUI.enabled = true;
 
		// Make an Ok button
		if (GUI.Button (Rect (0, 60, 150, 20), "Ok"))
			print ("user clicked ok");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public bool allOptions = true;
    public bool extended1 = true;
    public bool extended2 = true;
    void OnGUI() {
        allOptions = GUI.Toggle(new Rect(0, 0, 150, 20), allOptions, "Edit All Options");
        GUI.enabled = allOptions;
        extended1 = GUI.Toggle(new Rect(20, 20, 130, 20), extended1, "Extended Option 1");
        extended2 = GUI.Toggle(new Rect(20, 40, 130, 20), extended2, "Extended Option 2");
        GUI.enabled = true;
        if (GUI.Button(new Rect(0, 60, 150, 20), "Ok"))
            print("user clicked ok");
 
    }
