Description 描述

OnGUI is called for rendering and handling GUI events.

渲染和处理GUI事件时调用。

This means that your OnGUI implementation might be called several times per frame (one call per event). For more information on GUI events see the Event reference. If the MonoBehaviour's enabled property is set to false, OnGUI() will not be called.

这意味着你的OnGUI程序将会在每一帧被调用。要得到更多的GUI事件的信息查阅Event。如果Monobehaviour的enabled属性设为false，OnGUI()将不会被调用。

JavaScript:

function OnGUI () {
	if (GUI.Button (Rect (10,10,150,100), "I am a button"))
		print ("You clicked the button!");
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnGUI() {
        if (GUI.Button(new Rect(10, 10, 150, 100), "I am a button"))
            print("You clicked the button!");
 
    }
}
