Camera Rotation Around Player

Questions & Answers
1

So I have some code put in place currently trying to get my camera to rotate around my player in this case a Sphere. My issue is that all of the code is set in place for it to do just that. However when I go to rotate using the arrow keys it jerks back to the original rotation position. Any help would be greatly appreciated! ^~^

Here is the CameraOrbit.cs Script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraOrbit : MonoBehaviour {

    //Public Variables\\

    public GameObject targetObject;
    public Transform target;
    public float horizMove = 45f;
    public float vertMove = 15f;

    //Private Variables\\

    private Vector3 positionOffset = Vector3.zero;

    //Initiates on first frame\\

    void Start ()
    {
        positionOffset = transform.position - target.transform.position;
    }

    //Updates once per frame\\

    void Update ()
    {
        if (targetObject != null)
        {
            transform.LookAt (target.transform);
        }

        transform.position = target.transform.position + positionOffset;
    }

    //Movement Setup\\

    public void MoveHorizontal (bool left)
    {
        float dir = -1;
        if (!left)
            dir *= -1;
        transform.RotateAround (target.position, Vector3.up, horizMove * dir * Time.deltaTime);
    }

    public void MoveVertical (bool up)
    {
        float dir = -1;
        if (!up)
            dir *= -1;
        transform.RotateAround (target.position, transform.TransformDirection (Vector3.right), vertMove * dir * Time.deltaTime);
    }
}

And here is the InputManager.cs Script to allow the camera to rotate using the arrow keys:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class InputManager : MonoBehaviour {

    //Public Variables\\

    CameraOrbit cam;

    void Start ()
    {
        cam = GetComponent<CameraOrbit> ();
    }

    void Update ()
    {
        if (Input.GetKey (KeyCode.LeftArrow))
        {
            cam.MoveHorizontal (true);
        } else if (Input.GetKey (KeyCode.RightArrow))
        {
            cam.MoveHorizontal (false);
        } else if (Input.GetKey (KeyCode.UpArrow))
        {
            cam.MoveVertical (true);
        } else if (Input.GetKey (KeyCode.DownArrow))
        {
            cam.MoveVertical (false);
        }
    }
}

On line 34, inside your update function you have the following code:

transform.position = target.transform.position + positionOffset;

This snaps your camera back to position :slight_smile:
