Question by z25assassins · Apr 25, 2016 at 04:32 AM · directiontranform.position

How to move the Rigid body with respect to the camera angle

Not trying to beat a dead horse here because I know this question has been asked so many times. But I'm still having trouble trying to figure this out. I'm working on modifying the first tutorial from unity. I got my camera to move horizontally left and right, But when I go forward even though I am facing to either the left or right, When I press "up" I still am moving along the Z axis. So what I think I need to do(correct me if I'm wrong) is to change the Z axis with respect to the camera's current angle. This in turn will allow me to move forward in the direction of the camera?alt text

This is what I have tried to do "code wise". This is the Player class.

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;

 public class PlayerController : MonoBehaviour {
 public float speed;
 public Text countText;
 public Text winText; 
 private int count;

 public Vector3 movement;
 public CameraController c;
 private Rigidbody rb;
 public Transform target;
 public Vector3 targetDir;
 // Use this for initialization
 void Start () {
 
     rb = GetComponent<Rigidbody> ();
     count = 0;
     winText.text = ""; 
 }
 
 // Update is called once per frame
 //called before rendering a frame

 void Update () {
     transform.forward = new Vector3 (rb.position.x + c.directionView, 0, 0);
     transform.right = new Vector3 (0, 0, rb.position.y + c.directionView);
     print (transform.forward);
 }
 //called just before calling any physics calculations
 void FixedUpdate () {
     
     float moveHorizontal = Input.GetAxis("Horizontal");
     float moveVertical = Input.GetAxis("Vertical");
     movement = new Vector3 (moveHorizontal,0.0f,moveVertical);
     rb.AddForce (movement * speed);
     //rb.AddRelativeForce (movement*speed);
 }

 void OnTriggerEnter(Collider other){
     if(other.gameObject.CompareTag("Pick up")){
         
         other.gameObject.SetActive(false);
         count += 1;
         setCountText ();
     }
 }

 void setCountText(){
     countText.text = "Count : " + count.ToString ();

     if (count >= 8) {
         winText.text = "You Win!";
     }
 }
     

}

This is the Camera class.

 using UnityEngine;
 using System.Collections;

 public class CameraController : MonoBehaviour {
 PlayerController pc;
 public GameObject player;
 public float directionView;//camera direction left and right


 // Use this for initialization
 void Start () {
 }
 
 // Update is called once per frame
 void LateUpdate () {
     
     transform.position = player.transform.position;
     //transform.eulerAngles = new Vector3 (50, 0, 0);

     if (Input.GetKey ("right")){
         turnRight ();
     }
     else if (Input.GetKey ("left")) {
         turnLeft ();
     }
     else if (Input.GetKey ("up")) {
         transform.rotation = Quaternion.Euler (0, directionView, 0);
     }
     else if (Input.GetKey ("down")) {
         transform.rotation = Quaternion.Euler (0, directionView, 0);
     }
     print (directionView);
 }

 void turnRight(){
     directionView += 20;
     transform.rotation = Quaternion.Euler (0, directionView, 0);
     if (directionView == 360) {
         directionView = 0;
     }
 }
 void turnLeft(){
     directionView -= 20;
     transform.rotation = Quaternion.Euler (0, directionView, 0);
     if (directionView == -360) {
         directionView = 0;
     }
 }
     

}
