using UnityEngine;
using System.Collections;
public class ExampleClass : MonoBehaviour {
private Vector2 scale = new Vector2(1, 1);
private Vector2 pivotPoint;
void OnGUI() {
pivotPoint = new Vector2(Screen.width / 2, Screen.height / 2);
GUIUtility.ScaleAroundPivot(scale, pivotPoint);
if (GUI.Button(new Rect(Screen.width / 2 - 25, Screen.height / 2 - 25, 50, 50), "Big!"))
scale += new Vector2(0.5F, 0.5F);
}
