Numeric stepper

Is there a simple way to create a GUI numeric stepper? I need it for setting the matrix sizes in logical games.

There isn’t a built-in function for that, no. Sounds like you have this sorted anyway, but for reference, you can make your own function. It would be nicer if there was a GUI.NumberField, but there isn’t, so you pretty much have to make do with strings. Also you’d probably want to use some nice up/down textures for the buttons, instead of “^” and “V”.

function Stepper (position : Rect, text : String) : String {
	var size = position.height;
	text = GUI.TextField(Rect(position.x+size+2, position.y, position.width-size*2-4, size), text);
	var textValue = 0;
	var parsed = int.TryParse(text, textValue);
	if (GUI.Button(Rect(position.x, position.y, size, size), "V") ) {
		textValue--;
	}
	if (GUI.Button(Rect(position.x+(position.width-size), position.y, size, size), "^") ) {
		textValue++;
	}
	if (parsed) text = textValue.ToString();
	return text;
}

Which you use like this:

private var something = "0";

function OnGUI () {
	something = Stepper(Rect(10, 10, 100, 25), something);
}

Or, an alternate version:

function Stepper (position : Rect, text : String) : String {
	var size = position.height;
	text = GUI.TextField(Rect(position.x, position.y, position.width-size-2, size), text);
	var textValue = 0;
	var parsed = int.TryParse(text, textValue);
	if (GUI.Button(Rect(position.x+(position.width-size), position.y, size, size/2), "^") ) {
		textValue++;
	}
	if (GUI.Button(Rect(position.x+(position.width-size), position.y+size/2, size, size/2), "V") ) {
		textValue--;
	}
	if (parsed) text = textValue.ToString();
	return text;
}

If would not use a GUI you could use for loop like this.

var nextPositionX : int =10;
var nextPositionY : int =10;

var gridBox : GUITexture[];

function CreateGrid(){

for (var i = 0; i < gridBox.length; i++)
{ 
 gridBox*.pixelInset = Rect(nextPositionX,nextPositionY,100,100);*

nextPositionY += 110;
if(i == 5 || i == 10)
nextPositionX += 110;
}

}
but if you need to use GUI then you have to find another way.

I assume you mean a numeric slider control of some sort?

Take a look at the GUI Horizontal Slider
