Unity/Csharp/画像ロード

画像ロード(SpriteRendererを使う方法)

Sprite sp = Resources.Load<Sprite>("gazo");
GameObject gameObj = new GameObject();
SpriteRenderer spriteRenderer = gameObj.AddComponent<SpriteRenderer>();
spriteRenderer.sprite = sp;
gameObj.transform.parent = FindObjectOfType<Canvas>().transform;
gameObj.transform.localScale = new Vector3 (83, 83, 0);
gameObj.transform.name = "gazo";

slice画像ロード(SpriteRendererを使う方法)

Sprite[] sprites = Resources.LoadAll<Sprite>("gazo");
Sprite sp = System.Array.Find<Sprite>( sprites, (sprite) => sprite.name.Equals("gazo_1"));
GameObject gameObj = new GameObject();
SpriteRenderer spriteRenderer = gameObj.AddComponent<SpriteRenderer>();
spriteRenderer.sprite = sp;
gameObj.transform.parent = FindObjectOfType<Canvas>().transform;
gameObj.transform.localScale = new Vector3 (83, 83, 0);
gameObj.transform.name = "gazo_1";

画像ロード(Imageを使う方法)

Sprite sp = Resources.Load<Sprite>("gazo");
GameObject gameObj = new GameObject();
Image image = gameObj.AddComponent<Image>();
image.sprite = sp;
gameObj.transform.parent = FindObjectOfType<Canvas>().transform;
gameObj.transform.name = "gazo";
gameObj.transform.localScale = new Vector3 (1f, 1f, 0);

slice画像ロード(Imageを使う方法)

Sprite[] sprites = Resources.LoadAll<Sprite>("gazo");
Sprite sp = System.Array.Find<Sprite>( sprites, (sprite) => sprite.name.Equals("gazo_1"));
GameObject gameObj = new GameObject();
Image image = gameObj.AddComponent<Image>();
image.sprite = sp;
gameObj.transform.parent = FindObjectOfType<Canvas>().transform;
gameObj.transform.name = "gazo_1";
gameObj.transform.localScale = new Vector3 (1f, 1f, 0);

ImageのSourceImageをResourcesにある画像に切り替える

Assets/Resourcesに画像を準備（例：neko/img1.png)

Texture2D texture = Resources.Load("neko/img1") as Texture2D;
Image img = GameObject.Find("Canvas/Image1").GetComponent<Image>();
img.sprite = Sprite.Create(texture, new Rect(0, 0, texture.width, texture.height), Vector2.zero);
