Parameters 参数

position	Rectangle on the screen to use for the group. 用于组在屏幕上矩形的位置
text	Text to display on the group. 在组上显示的文本
image	Texture to display on the group. 在组上显示的纹理图片
content	Text, image and tooltip for this group. If supplied, any mouse clicks are “captured” by the group and not If left out, no background is rendered, and mouse clicks are passed. 用于组的文本，图片和提示，如果提供，任意鼠标点击被组捕获，如果不提供，不会渲染背景和传递鼠标点击。
style	The style to use for the background. 用于背景的样式。

Description 描述

Begin a group. Must be matched with a call to EndGroup.

开始组，必须配套以EndGroup结束关闭容器。

When you begin a group, the coordinate system for GUI controls are set so (0,0) is the top-left corner of the group. All controls are clipped to the group. Groups can be nested - if they are, children are clipped to their parents.

当你开始创建一个组，里面的GUI控件的坐标系统相对于组的左上角设置为0,0,所有的控件被限制到该组，组可以嵌套，子组将依附于父组。

This is very useful when moving a bunch of GUI elements around on screen. A common use case is designing your menus to fit on a specific screen size, then centering the GUI on larger displays. See Also: matrix, BeginScrollView.

JavaScript:

function OnGUI () {
		// Constrain all drawing to be within a 800x600 pixel area centered on the screen.
		GUI.BeginGroup (new Rect (Screen.width / 2 - 400, Screen.height / 2 - 300, 800, 600));
 
		// Draw a box in the new coordinate space defined by the BeginGroup.
		// Notice how (0,0) has now been moved on-screen
		GUI.Box (new Rect (0,0,800,600),
			"This box is now centered! - here you would put your main menu");
 
		// We need to match all BeginGroup calls with an EndGroup
		GUI.EndGroup ();
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnGUI() {
        GUI.BeginGroup(new Rect(Screen.width / 2 - 400, Screen.height / 2 - 300, 800, 600));
        GUI.Box(new Rect(0, 0, 800, 600), "This box is now centered! - here you would put your main menu");
        GUI.EndGroup();
    }
}
