how to make an object following another object rotating around a circle?
So, object A stands still and rotates in a circular motion, right? Then you can just pass this object’s transform.rotation to the transform.rotation of the object that should follow it. If you only want to use the y rotation, then take the y value of the first object’s eulerAngles and pass it to the second object’s eulerAngles.
Transform object_a; Transform object_b; float euler_y = object_a.eulerAngles.y; object_b.eulerAngles = new Vector3(object_b.eulerAngles.x, euler_y, object_b.eulerAngles.z);
If the following object should rotate towards the edge of the circle, then you just take the first object’s transform.positon and add it’s forward direction vector times the radius.
Transform object_a; Transform object_b; float radius = 3f; Vector3 circleEdgePos = object_a.position + object_a.forward * radius; object_b.LookAt(circleEdgePos );
