How to change the width of a Tiled sprite from script?

Question

I'm making a Health Bar prefab (see screenshot). I use an image of a square that I repeat with Draw Mode set to Tiled to divide the bar into squares. I want enemies with more health to have longer bars with more squares. When I change the Width in the inspector, it works as expected (the bar appears longer or shorter and more squares are added or removed accordingly). However, when I change the width in code, nothing happens.

alt text

I tried setting SpriteRenderer.size but it doesn't do anything (the width and height of my SpriteRenderer don't change). The doc says Property to set/get the size to render when the SpriteRenderer.drawMode is set to SpriteDrawMode.Sliced. and in my case, the Draw Mode is not set to Sliced. Even if I set the DrawMode to Sliced (which isn't what I want) it doesn't do anything either. So how do I change the width of my Tiled Sprite through code?

I can't use SpriteRenderer.transform.localScale because that would stretch the bar without adding more squares.

EDIT: The problem was that I was using mySpriteRenderer.size.Set(widht, height); I used mySpriteRenderer.size = new Vector2(width, height); instead and it worked.

Just did this simple script for making sure it workded and everything seems fine, Just create a SpriteRenderer object and copy that lines in start, then just play with the vector2 vars for adjusting it to you gameplay mechanic.

 void Start()
 {
      spriteRenderer = GetComponent<SpriteRenderer>();
      spriteRenderer.drawMode = SpriteDrawMode.Tiled;
      spriteRenderer.size = new Vector2(5,1);
 }

Good day.

How do you try to change it?

Spriterenderer size is a Vector2 variable, you should be able to change it as the documentation says.

https://docs.unity3d.com/ScriptReference/SpriteRenderer-size.html

 sprRend.size += new Vector2(0.05f, 0.01f);

or

 sprRend.size = new Vector2(3, 1);

Bye!
