Unity 3D integrates an ecosystem of tools highly used lately for mobile game development: a powerful rendering engine fully integrated with a complete set of intuitive tools and rapid workflows to create interactive 3D and 2D content; easy multiplatform publishing; thousands of quality, ready-made assets in the Asset Store and a knowledge-sharing community.
GUI.SelectionGrid static function SelectionGrid(position: Rect, selected: int, texts: string[], xCount: int) :int; static function SelectionGrid(position: Rect, selected: int, images: Texture[], xCount: int) :int; static function SelectionGrid(position: Rect, selected: int, content: GUIContent[], xCount: int) :int; static function SelectionGrid(position: Rect, selected: int, texts: string[], xCount: int, style: GUIStyle) :int; static function SelectionGrid(position: Rect, selected: int, images: Texture[], xCount: int, style: GUIStyle) :int; static function SelectionGrid(position: Rect, selected: int, content: GUIContent[], xCount: int, style: GUIStyle) :int; Parameters position Rectangle on the screen to use for the grid. selected The index of the selected grid button. texts An array of strings to show on the grid buttons. images An array of textures on the grid buttons. contents An array of text, image and tooltips for the grid button. xCount How many elements to fit in the horizontal direction. The controls will be scaled to fit unless the style defines a fixedWidth to use. Style The style to use. If left out, the button style from the current GUISkin is used.
In all types of games you will find a Graphical User Interface (GUI), designed to be as attractive as possible. One of the many functions that Unity has to help design a spectacular GUI is the SelectionGrid. With this you can make a grid of buttons very easily.
In the following snippet, you can find an easy way to center the grid on screen and, if you don’t want to use the SelectionGrid, you can always use the plain old Button.
#pragma strict //Public Variables public var selectionGrid : Boolean; //Private Variables private var selGridInt : int =0; private var selectionStrings : String[]; private var btnPos : Rect; private var btnWidth : int; private var btnHeight : int; function Start(){ selectionStrings = [“Grid1”, “Grid2”, “Grid3”, “Grid4”]; btnWidth = 200; btnHeight = 60; btnPos = Rect(Screen.width/2 – btnWidth – 10, Screen.height/2 – 65, btnWidth, btnHeight); } function OnGUI(){ if(selectionGrid){ selGridInt = GUI.SelectionGrid( Rect (Screen.width/2 – btnWidth/2, Screen.height/2 – btnHeight – 5, btnWidth, btnHeight), selGridInt, selectionStrings, 2); } else{ GUI.Button(btnPos, “Grid1”); GUI.Button(Rect(btnPos.x + btnWidth + , btnPos.y, btnWidth, btnHeight), “Grid2”); GUI.Button(Rect(btnPos.x, btnPos.y + 65, btnWidth, btnHeight), “Grid3”); GUI.Butoon(Rect(btnPos.x + btnWidth + 5, btnPos.y + 65, btnWidth, btnHeight), “Grid4”); } }
As displayed, using the SelectionGrid you can create a grid of buttons with only one line of code.
