Creating sprite in code using TextureImporter with C#?
I'm trying to create a Sprite based on an external texture. The intended functionality once I finish is that a user would be able to select a photo from an external source and use that as their sprite. My problem is trying to convert that texture into a sprite, which so far I haven't been able to do.
using UnityEngine;
using UnityEditor;
public Material defaultMaterial; //prefab material set already
IEnumerator Start()
{
SpriteRenderer renderer = gameObject.GetComponent<SpriteRenderer>();
string path = "file://C:\\Users\\i5\\Documents\\My2DProject\\Assets\\oranges.png";
TextureImporter tImport = AssetImporter.GetAtPath(path) as TextureImporter;
TextureImporterSettings tImportSettings = new TextureImporterSettings();
tImport.isReadable = true;
//Throws an error NullReferenceException: Object reference not set to an instance of an object
tImport.textureType = TextureImporterType.Sprite;
tImportSettings.spriteMode = 1;
tImport.SetTextureSettings(tImportSettings);
renderer.sprite = //How can I convert the oranges.png texture into a sprite with TextureImporter tImport? I'm stuck on this part.
renderer.material = defaultMaterial;
}
Solved my problem, here is the solution. Note you can swap the path for a URL if you want to load an image from the web.
using UnityEngine;
using UnityEditor;
public Material defaultMaterial; //prefab material set already
IEnumerator Start()
{
string path = "file://C:\\Users\\i5\\Documents\\My2DProject\\Assets\\oranges.png";
WWW www = new WWW(path);
yield return www;
SpriteRenderer renderer = gameObject.GetComponent<SpriteRenderer>();
Sprite sprite = new Sprite();
sprite = Sprite.Create(www.texture, new Rect(0, 0, 170, 170),new Vector2(0, 0),100.0f);
renderer.sprite = sprite;
renderer.material = mat;
}

Hey, I'm searching for the same functionality. What do you mean by "prefab material set already" ? How do I do that? Thanks.
nice information.. but now the picture's quality will be down (resolution). how to make the picture's resolution same with the picture real ??
