Editing/chaging a sprite's texture

I need to able to edit a sprite’s texture in the game I’m making in order to show damage, this was fairly easy using quads, however I can’t seem to find a way to do this using sprites, sprite.texture is read-only and I can’t seem to get Sprite.Create to work properly (even though the texture to use in the sprite is generated without any problem, the generated sprite is always a solid color no mater what I do). Any ideas?

It seems to me that you cannot change the texture, you should create a whole new Sprite for the SpriteRenderer, like this for example :

 SpriteRenderer sr = GetComponent<SpriteRenderer>();
 sr.sprite = Sprite.Create(yourTexture2D, new Rect(0, 0, yourTexture2D.width, yourTexture2D.height), new Vector2(0, 0), pixelsToUnitfloat);

Check Sprite.Create doc

In the import inspector of the texture, select advanced and tick Read/Write.

That will allow you to modify your texture.

But think what you are after is more likely to change a texture.

So you need to have an array of texture:

   public Sprite[] textures;
   SpriteRenderer sp;

   void Start()
   {
      sp = GetComponent<SpriteRenderer>();
      sp.sprite = textures[0];
   }  

   void Damage(int damage)
   {
       health -= damage;
       if(health > 80 ) 
            sp.sprite= textures[0];
       else if(health <= 80 && health > 50) 
            sp.sprite = textures[1];
       // And so on
   }

isn’t that working?
