JavaScript => public static function ScaleAroundPivot(scale: Vector2, pivotPoint: Vector2): void;
C# => public static void ScaleAroundPivot(Vector2 scale, Vector2 pivotPoint);

Description 描述

Helper function to scale the GUI around a point.

使GUI沿一个点缩放的辅助函数。

Modifies GUI.matrix to rotate all GUI elements angle degrees around pivotPoint.

修改GUI.matrix来绕轴点旋转所有GUI元素的角度。

JavaScript:

	// Scale a button by 1.5 times each time is pressed.
 
	private var scale : Vector2 = Vector2(1,1);
	private var pivotPoint : Vector2;
 
	function OnGUI () {   
		pivotPoint = Vector2(Screen.width/2,Screen.height/2);
		GUIUtility.ScaleAroundPivot (scale, pivotPoint); 
		if(GUI.Button(Rect(Screen.width/2-25, Screen.height/2-25, 50, 50),"Big!")){
			scale += Vector2(0.5,0.5);
		}		
	}

C#:

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);
 
    }
}
