Loading a Dynamic Sprite and Animating it...

So with my game, I want to make it modable by the end users, so with that in mind I'm putting all the graphics, etc... as files on disk.

I can load a single sprite easy enough and assign it to a game object.

Code (CSharp):

1.            
2.             fileData = System.IO.File.ReadAllBytes(fileName);
3.  
4.             Image = new Texture2D(ImageWidth, ImageHeight, TextureFormat.BGRA32, false);
5.             Image.LoadImage(fileData);
6.  

I then later create the sprite on the game object as:

Code (CSharp):

1.  
2.             renderer = gameObject.GetComponent<SpriteRenderer>();
3.  
4.             renderer.sprite = Sprite.Create(Image, rect, new Vector2(0.5f, 0.5f));
5.  

This issue I'm trying to overcome is if I have an image that contains multiple cells of an animated sprite.

So I have an image that has a 32 x 32 sprite. The Image might be 128 x 32 which would give me 4 frames of animation for the 32 x 32 sprite.

Basically, I would have an animation speed on my class, what frame it should be currently showing and a reference to the large image with all the frames.

Do I manually load the full image in, then create multiple images as a collection, or is there a more efficient way to do it in Unity with the single image?

Thanks!

 

No one is loading sprites from disk and animating them?
