How to limit pinch scale of an object in AR?
Hello, im new to Unity and i would like to know whats the best way to limit localScale of an Object thats been scaled via touch gesture in AR? The user shouldn't be able to scale up the object to high/low.
My code:
void Scale()
{
Touch t1 = touches[0];
Touch t2 = touches[1];
if (t1.phase == TouchPhase.Began || t2.phase == TouchPhase.Began)
{
initialFingersDistance = Vector2.Distance(t1.position, t2.position);
initialScale = curSelected.transform.localScale;
}
else if (t1.phase == TouchPhase.Moved || t2.phase == TouchPhase.Moved)
{
float currentFingersDistance = Vector2.Distance(t1.position, t2.position);
float scaleFactor = currentFingersDistance / initialFingersDistance;
curSelected.transform.localScale = initialScale * scaleFactor;
}
}
I appreciate any help :)
