Rotate around an object to its direction of velocity (C#)
Right now I am working on a 3D camera that is orbiting horizontally around the player. The player is a RigidBody rolling sphere. The player can freely rotate the axis horizontally but when there is no input I want the rotation to reset back to the direction of the velocity.
Right now all I need to know is how to situate the camera behind the player's direction of velocity by rotating the camera around the player.
Here is a crude drawing of what I am looking for:
Currently to update the camera to orbit around the player I use this script on the camera (with comments):
using UnityEngine;
using System.Collections;
public class example : MonoBehaviour {
public GameObject Player;
//I assume you would use this PlayerRB to find data regarding the movement or velocity of the player.
//public Rigidbody PlayerRB;
private float moveHorizontalCamera;
private Vector3 offset;
// Use this for initialization
void Start ()
{ //the offset of the camera to the player
offset = new Vector3(Player.transform.position.x - transform.position.x, transform.position.y - Player.transform.position.y, transform.position.z - Player.transform.position.z);
}
// Update is called once per frame
void Update ()
{
moveHorizontalCamera = Input.GetAxis("Joy X"); //"Joy X" is my right joystick moving left, none, or right resulting in -1, 0, or 1 respectively
//Copied this part from the web, so I half understand what it does.
offset = Quaternion.AngleAxis(moveHorizontalCamera, Vector3.up) * offset;
transform.position = Player.transform.position + offset;
transform.LookAt(Player.transform.position);
}
}
Any help at all would be great!
Bump? Still have not figured this out. Should I use an external library or change my approach or something? :(
