Sprite sheets in Resource folder

Questions & Answers
1

Historically, when I have a sprite sheet in my Sprites folder (not in Resources), and I want to swap in sprites at runtime, I have always dragged the sprites one at a time into my scene, then created prefabs in Resources for every single sprite. Cumbersome and feels wrong.

However, is there a way to just put my entire Sprite sheet in Resources, and use them via script without creating individual sprites for every sliced image in the sheet?

Example:
I have a figure that I want to change the head sprite for. I have a sprite sheet in Resources that is sliced up into 20 different head images. How can I select out head_12 from the sprite sheet and use it for my head graphic? Javascript if possible please.

Once you imported your texture as multiple sprites you can load all sprites “inside” that texture using:

Sprite[] sprites = Resources.LoadAll<Sprite>(pathToTexture);

Then you can get any sprite on that array and check it’s .name to select the one you want.

I’ve searched a lot and can’t find a way to load only one sprite by it’s name if it’s inside a texture.

You can write:

Sprite sprite = Resources.Load<Sprite>(pathToTexture);

And you’ll get the first sprite in the list.

You can also make a static function so whenever you want a specific sprite from any script, you can call the function

for example, put this in (any) fooScript.js

static function GetSprite(path : String, spr : String){

 sp = Resources.LoadAll.<Sprite>(path);
	 for(x in sp)
		 if(x.name.Contains(spr))
			 return x;
}

now to get a sprite whenever you want, do this

fooScript.GetSprite("spriteFolder/spriteSheetFoo", "fooSPrite");
