请帮我写一个在unity2d中检测image02是否显示。显示时按s键image移动至屏幕中央并放大，按←键图片顺时针旋转90度，按→键图片逆时针旋转90度，并且点击image02后能缩小为原来大小的代码

以下是一个简单的示例代码，用于检测Unity2D中的Image是否显示，并在按下特定键时对其进行操作：

using UnityEngine;
using UnityEngine.UI;

public class ImageController : MonoBehaviour {
    public Image image02;
    private bool isImageVisible = false;
    private bool isImageSelected = false;

    void Update () {
        if (image02.gameObject.activeSelf && !isImageVisible) {
            // Image is visible
            isImageVisible = true;
        }

        if (isImageSelected) {
            // Image is selected, handle input events
            if (Input.GetKeyDown(KeyCode.S)) {
                // Move and scale image
                image02.transform.position = new Vector3(Screen.width / 2, Screen.height / 2, 0);
                image02.transform.localScale = new Vector3(2, 2, 2);
            } else if (Input.GetKeyDown(KeyCode.LeftArrow)) {
                // Rotate image clockwise
                image02.transform.Rotate(Vector3.forward * 90);
            } else if (Input.GetKeyDown(KeyCode.RightArrow)) {
                // Rotate image counterclockwise
                image02.transform.Rotate(Vector3.forward * -90);
            } else if (Input.GetMouseButtonDown(0)) {
                // Click on image, shrink it to original size
                image02.transform.localScale = new Vector3(1, 1, 1);
                isImageSelected = false;
            }
        } else {
            // Image is not selected, check for selection
            if (Input.GetMouseButtonDown(0)) {
                Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
                if (image02.rectTransform.rect.Contains(mousePosition)) {
                    isImageSelected = true;
                }
            }
        }
    }
}

此代码将检测名为image02的Image是否在场景中显示，并在其被选择时响应键盘和鼠标输入事件。按下S键将使图像移动到屏幕中央并放大，按下←和→键将使图像顺时针或逆时针旋转90度，单击图像将使其缩小到原始大小。
