GroupScope

Description

Disposable helper class for managing BeginGroup / EndGroup.

BeginGroup is called at construction, and EndGroup is called when the instance is disposed. 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.

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.

using UnityEngine;

public class Example : MonoBehaviour {
	void OnGUI() {
		// Constrain all drawing to be within a 800x600 pixel area centered on the screen.
		using(var groupScope = new GUI.GroupScope(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");
		}
		// The group is now ended.
	}
