Rotate object to a specific angle and then stop.
I need to be able to define a rotation value in all three axis, have the object rotate to that point over a certain time period (which I also define in a variable), and then have it stop moving once it reaches that point (or gets within 1 or 2 units of the point).
How do I do this?, Transform.Rotate doesn't seem to let me specify a specific point to go to, and I have no idea how to use Quaternions.
So, you want to animate the rotation value over time until it reaches a certain value.
Inside the Update method, you can use the Lerp method to keep rotating the object to a point, but you will never really reach this point if you use Lerp. It will keep rotating forever (always closer to the point).
You can use the following:
private bool rotating = true;
public void Update()
{
if (rotating)
{
Vector3 to = new Vector3(20, 20, 20);
if (Vector3.Distance(transform.eulerAngles, to) > 0.01f)
{
transform.eulerAngles = Vector3.Lerp(transform.rotation.eulerAngles, to, Time.deltaTime);
}
else
{
transform.eulerAngles = to;
rotating = false;
}
}
}
So, if the distance between the current object angle and the desired angle is greater than 0.01f, it jumps right to the desired position and stop executing the Lerp method.
I turn again and again..... never stop... doesnt works
This works for me... I hope it helps you:
void Update (){ if (rb.transform.rotation.z != (out2 )) StartCoroutine (RotateZell ());
}
IEnumerator RotateZell () { while(rb.transform.rotation.z < out2 || rb.transform.rotation.z > out2) { rb.transform.rotation = Quaternion.Slerp(rb.transform.rotation, Quaternion.Euler(0, 0, out2), 0.1f * Time.time); yield return null; }
rb.transform.rotation = Quaternion.Euler(0, 0, out2);
yield return null;
}
