Unity streching sprite gameobject to fit two positions.

Question

Hello.

I have a sprite gameobject, which I want to scale by x axis in order to fit it between two points.

I have this script:

 public void strechBetween(Vector2 point1, Vector2 point2)
 {
     
     Vector3 scale = transform.localScale;
     scale.x = Vector3.Distance(point1, point2);
     transform.localScale = scale;
 }

But it streches to much. Is there any other solutions?

I haven't tested this but you are forgetting to factor in the size of the sprite in units. try this

 public void strechBetween(Vector2 point1, Vector2 point2)
  {
      float spriteSize = GetComponent<SpriteRenderer>.sprite.rect.width / GetComponent<SpriteRenderer>.sprite.pixelsPerUnit;
      
      Vector3 scale = transform.localScale;
      scale.x = (point1.x - point2.x) / spriteSize;
      transform.localScale = scale;
  }

@$$anonymous$$Watts Oh I forgot. This worked, but with scale.x = Vector3.Distance(point1, point2) / spriteSize; Please write it as answer so I could accept it.

yea you should probably use $$anonymous$$athf.Abs( point1.x - point2.x ) / spriteSize i forgot to put that in. that way it will still work if the y values of the points are different.
