Changing the size and sprite of an object during the game?

Question

Unity

So that from, for example, such a rectangle


, it turns into this


If you just throw a sprite, then the dimensions do not change and this is what happens

Answer 1

float spritePos = _collider2D.bounds.max.y + _groundCollider.bounds.max.y;
spritePos = spritePos * 1.5f;
_transform.position = new Vector2(_transform.position.x, spritePos);

Fix for changing the position by colliders (of the object and the ground on which it should stand)

Answer 2

Just pull the top blue circle up and make it the size you need.

Answer 3

The scale property of the transform component is responsible for the size of the object.
