Question by KloverGames · Jun 22, 2018 at 06:20 PM · rotationquaternionchild object

The rotation keeps resetting after I stop input, how do I keep the rotation even after the input has stopped?

I made a child for the player to rotate around, it works fine but the rotation resets when input has stopped. Here's my code.

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

public class RotateChild : MonoBehaviour {

 public Transform child;
 private float rotSpeed = 5.0f;

 // Update is called once per frame
 void FixedUpdate () {
     {
         transform.LookAt (child);
     }

     {
         if (Input.GetKey (KeyCode.RightArrow))
             transform.RotateAround (Vector3.zero, Vector3.up, rotSpeed * Time.deltaTime);
     }

     {
         if (Input.GetKey (KeyCode.LeftArrow))
             transform.RotateAround (Vector3.zero, Vector3.down, rotSpeed * Time.deltaTime);
     }
 }

}

You need a value to save the state.

 public Transform child;
 private float rotSpeed = 5.0f;
 private int rotateDir = 0;
 
 void FixedUpdate () {
     transform.LookAt (child);
 
     if (Input.GetKey (KeyCode.RightArrow))
         rotateDir = 1;
 
     if (Input.GetKey (KeyCode.LeftArrow))
         rotateDir = -1;
 
     if(rotateDir != 0)
         transform.RotateAround (Vector3.zero, Vector3.up*rotateDir , rotSpeed * Time.deltaTime);
 
 }
