Having issues with RotateAround and over rotation in a 2d project

Hello All,
I’m having some difficulty with the function RotateAround a specific point and over rotation.I want this to look somewhat smooth so I’m using speed as a function of angle and delta time.

I’ve got some code to try and stop the rotation when the distance is close but I really want to stop the rotation perfectly and I’m having a heck of a time figuring out exactly how to do that.

I’ve seen some examples that use lerp, slerp, and quaternions but it’s been I while since I’ve worked with Quaternions and could use some help. What I have now is as follows:


bool _isRotating = true;
float _rotationAngle = 180; //degrees
Vector3 EndingPosition = a RotateAround computation with the full 180 degrees.

void PerformRotation()
{
if (_isRotating && _rotationAngle != 0f)
{
float speed = _rotationAngle * Time.deltaTime;
MyClayTarget.transform.RotateAround(MyHunter.transform.position, Vector3.forward, speed);

if (Vector3.Distance(MyClayTarget.transform.position, EndingPosition) < 1.0f)
{
_isRotating = false;
_rotationSpeed = 0f;
}
}
}


Thank you!
Robert
