Parameters

Name	Description
position	Rectangle on the screen to use for the group.
text	Text to display on the group.
image	Texture to display on the group.
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

Description

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

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. See Also: matrix, BeginScrollView.

JavaScripts

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 ();
}
