Just a quickie -

How do I gradually shrink an object?

Couldn’t find on a search
Thanks

In your update function:

public float targetScale = 0.1f;
public float shrinkSpeed = 0.1f;
cone.transform.localScale = Vector3.Lerp(cone.transform.localScale, new Vector3(targetScale, targetScale, targetScale), Time.deltaTime*shrinkSpeed);

Or alternatively:

public float targetScale = 0.1f;
public float shrinkSpeed = 0.1f;

void Shrink() {
	shrinking = true;
}

void Update() {
	if (shrinking) {
		cone.transform.localScale -= Vector3.one*Time.deltaTime*shrinkSpeed;
		if (cone.transform.localScale < targetScale)
			shrinking = false;
	}
}

Note that while the first option looks quite neat, it will never quite reach your target scale and will keep on adjusting it by a tiny amount forever.
