Rotate object around moving object

[Scobbo]

Hello,
I have some spinning cubes I want to follow the player by orbiting around it. I had it working nicely, when the player was too far they would move into range then rotate around the player. The problem is when they are orbiting, and the player moved, they would just follow normally until they were within range again. I tried to fix this with the following script but it tells me I can’t modify the rotate directly so I should store it in a temporary variable. I’m sorry it looks awful I have bastardized it trying to get rid of this error.

void Orbit()
    {
		currentRot += speed * Time.deltaTime;
		Vector3 tempVec = new Vector3(0, currentRot, 0);
		rotate.eulerAngles = tempVec;
		transform.rotation.eulerAngles = tempVec;
		transform.position = rotate * radius + target.position;
    }

If someone could kindly help I would be very appreciative.

Kindest regards!

Try this to orbit a moving target. I didn’t know what type of orbit you were wanting, so I assume you wanted to orbit around the target’s Y (UP) axis.

using UnityEngine;
using System.Collections;

public class OrbitPlayer : MonoBehaviour {

	public Transform target;
	public float orbitDistance = 10.0f;
	public float orbitDegreesPerSec = 180.0f;
	
		// Use this for initialization
	void Start () {
	
	}
	
	void Orbit()
	{
		if(target != null)
		{
			// Keep us at orbitDistance from target
			transform.position = target.position + (transform.position - target.position).normalized * orbitDistance;
			transform.RotateAround(target.position, Vector3.up, orbitDegreesPerSec * Time.deltaTime);
		}
	}
	
	// Update is called once per frame
	void Update () {
		
		// Call from LateUpdate instead...
            // Orbit();
	
	}

    // Call from LateUpdate if you want to be sure your
    // target is done with it's move.
	void LateUpdate () {
		
		Orbit();
	
	}
}

I know this is an older topic but since i used this script myself, i thought i’d add to it
to make it so that you can set the distance of the orbit.

using UnityEngine;
using System.Collections;

public class RotateAroundPlayer : MonoBehaviour {

// Use this for initialization
	
	public Transform target;
	public float orbitDistance = 3.0f;
	public float orbitDegreesPerSec = 180.0f;
	public Vector3 relativeDistance = Vector3.zero;
	public bool once = true;
	// Use this for initialization
	void Start () {
		
		if(target != null) 
		{
			relativeDistance = transform.position - target.position;
		}
	}
	
	void Orbit()
	{
		if(target != null)
		{
			// Keep us at the last known relative position
			transform.position = (target.position + relativeDistance);
			transform.RotateAround(target.position, Vector3.up, orbitDegreesPerSec * Time.deltaTime);
			// Reset relative position after rotate
		if (once)
		{
			transform.position *= orbitDistance;
			once = false;
		}
			relativeDistance = transform.position - target.position;
		}
	}
	
	void LateUpdate () {
		
		Orbit();
		
	}
}

That is all
