Parameters

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.

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 ();
}
