修改 GUI.matrix 可以让所有 GUI 元素围绕 pivotPoint
旋转 angle
度。

using UnityEngine;
public class Example : MonoBehaviour { // Rotate a button 10 degrees clockwise when presed.
float rotAngle = 0; Vector2 pivotPoint;
void OnGUI() { pivotPoint = new Vector2(Screen.width / 2, Screen.height / 2); GUIUtility.RotateAroundPivot(rotAngle, pivotPoint); if (GUI.Button(new Rect(Screen.width / 2 - 25, Screen.height / 2 - 25, 50, 50), "Rotate")) { rotAngle += 10; } } }
