如何在Unity中使用代码获取/更改图像源名称？

Question

我们创建了一个脚本并需要获取图像名称，我们在下面以笨拙的方式实现此任务，但我们仍然想知道是否有办法直接获取图像名称？

public class CubeManager
{
    static public Dictionary<CubeType, string> cubeTypeDict = new Dictionary<CubeType, string>();
    static private Dictionary<string, GameObject> cubeDict = new Dictionary<string, GameObject>();
    static CubeManager()
    {
        cubeTypeDict.Add(CubeType.Wall01, "Wall01");
        cubeTypeDict.Add(CubeType.Wall02, "Wall02");
        cubeTypeDict.Add(CubeType.Wall03, "Wall03");
        cubeTypeDict.Add(CubeType.Wall04, "Wall04");
        cubeTypeDict.Add(CubeType.Wall05, "Wall05");
        cubeTypeDict.Add(CubeType.Wall06, "Wall06");
        cubeTypeDict.Add(CubeType.Wall07, "Wall07");
        cubeTypeDict.Add(CubeType.Wall08, "Wall08");
        cubeTypeDict.Add(CubeType.Wall09, "Wall09");
        cubeTypeDict.Add(CubeType.Wall10, "Wall10");
        cubeTypeDict.Add(CubeType.Wall11, "Wall11");
        cubeTypeDict.Add(CubeType.Wall12, "Wall12");
        cubeTypeDict.Add(CubeType.Wall13, "Wall13");
        cubeTypeDict.Add(CubeType.Wall14, "Wall14");
        cubeTypeDict.Add(CubeType.Wall15, "Wall15");
        cubeTypeDict.Add(CubeType.Wall16, "Wall16");
        cubeTypeDict.Add(CubeType.Wall17, "Wall17");
        cubeTypeDict.Add(CubeType.Wall18, "Wall18");
        cubeTypeDict.Add(CubeType.Wall19, "Wall19");
        cubeTypeDict.Add(CubeType.Wall20, "Wall20");
        cubeTypeDict.Add(CubeType.Wall21, "Wall21");
        cubeTypeDict.Add(CubeType.Wall22, "Wall22");
        cubeTypeDict.Add(CubeType.Wall23, "Wall23");
        cubeTypeDict.Add(CubeType.Wall24, "Wall24");
        cubeTypeDict.Add(CubeType.Wall25, "Wall25");
        cubeTypeDict.Add(CubeType.Wall26, "Wall26");
        cubeTypeDict.Add(CubeType.Wall27, "Wall27");
        cubeTypeDict.Add(CubeType.Wall28, "Wall28");
        cubeTypeDict.Add(CubeType.Wall29, "Wall29");
    }

Answer 1

是的，你可以，

Image img;

Debug.Log("Image Name: " + img.sprite.name);

此外，您还可以通过提供Texture2D

来更改精灵

img.sprite = Sprite.Create (spr.texture, img.sprite.rect, new Vector2 (0.5f, 0.5f));

此处spr是精灵，您可以直接使用Texture2D。

Answer 2

this.transform.gameobject.GetComponent<Image> ().name;
