How do I replace a sprite in script?

Question

I'm trying to replace a gameobject's sprite via script. I can't seem to find a way to do it. I've attempted replacing the texture after loading it via resources, but it doesn't help.

This is what I'm trying to do:

 Texture2D texture = Resources.Load<Texture2D>("Wall_Vertical");
 wall.renderer.material.SetTexture("Wall_Vertical", texture);

Since 4.3 released very recently there isn't much info out there. Anyone got an idea?

The easiest way I've found so far:

 Sprite spr = Resources.Load<Sprite>("SpriteName");
 SpriteRenderer sprRenderer= (SpriteRenderer)renderer;
 sprRenderer.sprite = spr;

No amount of fiddling around with the renderer's material got me anywhere, but getting the GameComponent's SpriteRenderer and just applying the sprite directly to it seems to work. I have no idea how this method is for performance, but it works.

Thank you this worked for me

I am trying to make a card game with playing cards and did not wnat 52 textures, this seems like i can mix numbers and a picture to represent suit.

And after a qick look i also found the next pice i wanted to be able to make the numbers red or black to make it easier to tell suit i used this pice of code

 sprRenderer.color = new Color (1, 0, 0, 1);

at the end of Skitzomaniak's code to make it red

i found the info here

Place awesome.png in Assets/Resources/ (you can have subfolders), and use:

 GetComponent<SpriteRenderer>().sprite = 
     Resources.Load<Sprite>("awesome");  // No file extension.

http://docs.unity3d.com/ScriptReference/Resources.html

There's also LoadAll that "Loads all assets in a folder or file at path in a Resources folder."

Sorry for reviving this, but you cannot have sub folders inside the resources folder. You can however put the resources folder inside a sub folder inside the assets folder.

Well, you should be sorry, because you're wrong. You CAN have subfolders in Resources.

It has been a feature since 7+ years ago.
