class in UnityEngine
Disposable helper class for managing BeginGroup / EndGroup.
管理BeginGroup / EndGroup的可支配的助手类。
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.
BeginGroup 在结构中被调用,并且当实例被处理时调用EndGroup 。当形成组时,GUI控制台的坐标系统被设置为(0,0)即组的左上角位置。所有控件都被都剪裁到组。组可以被嵌入——如果他们是子物体剪裁到父物体。
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.
当在屏幕中移动GUI元素时这是有用的。一个普通的用法是设计你的菜单去适合指定的屏幕尺寸,然后显示在GUI中心。

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. } }
GUI.GroupScope | Create a new GroupScope and begin the corresponding group. 创建新的组范围并形成相对应的组。 |
