説明

GUI オブジェクトを回転させるヘルパー関数

pivotPoint を回るすべての GUI エレメントを angle 度回転させるために GUI.matrix を変更します。

関連項目: GUI.matrix、ScaleAroundPivot.

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;
        }
    }
}
