player moves in direction of camera? And faces their direction of movement?c#

Unity Engine
1

Hello, newbie here. As stated in the title, I want the character to move in the direction of the camera, but still allowing the character to face their direction of movement. For example, if i press “d” the character turns and moves right, but if the camera is turning right and i press “w” for forward, the character moves right in the game world. Basically like Dark Souls, GTA, or Assassin’s Creed

Movement code

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {
    public static float playerSpeed = 3.5F;
    public static float rollSpeed = 20.0F;
	public static float sprint = 7f;
    public float gravity = 20.0F;
    private Vector3 moveDirection = Vector3.zero;
	
	
	
    void Update() {
		
		
		
        CharacterController controller = GetComponent<CharacterController>();
		
        if (controller.isGrounded) {
			
            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
			
            moveDirection = transform.TransformDirection(moveDirection);
			
            moveDirection *= playerSpeed;
			
        if (Input.GetButtonUp("Roll"))
                moveDirection.x = rollSpeed;
			
 		if (Input.GetButtonDown("Sprint")){

   		 playerSpeed += sprint;

		if (Input.GetButtonUp("Sprint"))

  		 playerSpeed -= sprint;
			}
        }
        moveDirection.y -= gravity * Time.deltaTime;
        
        controller.Move(moveDirection * Time.deltaTime);
    }
}

Camera code(just mouse orbit in the wiki)

using UnityEngine;
using System.Collections;
 
[AddComponentMenu("Camera-Control/Mouse Orbit with zoom")]
public class MouseOrbit: MonoBehaviour {
 
    public Transform target;
    public float distance = 5.0f;
    public float xSpeed = 120.0f;
    public float ySpeed = 120.0f;
 
    public float yMinLimit = -20f;
    public float yMaxLimit = 80f;
 
    public float distanceMin = .5f;
    public float distanceMax = 15f;
 
    float x = 0.0f;
    float y = 0.0f;
 
	// Use this for initialization
	void Start () {
        Vector3 angles = transform.eulerAngles;
        x = angles.y;
        y = angles.x;
 
        // Make the rigid body not change rotation
        if (rigidbody)
            rigidbody.freezeRotation = true;
	}
 
    void LateUpdate () {
    if (target) {
        x += Input.GetAxis("Mouse X") * xSpeed * distance * 0.02f;
        y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
 
        y = ClampAngle(y, yMinLimit, yMaxLimit);
 
        Quaternion rotation = Quaternion.Euler(y, x, 0);
 
        distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel")*5, distanceMin, distanceMax);
 
        RaycastHit hit;
        if (Physics.Linecast (target.position, transform.position, out hit)) {
                distance -=  hit.distance;
        }
        Vector3 negDistance = new Vector3(0.0f, 0.0f, -distance);
        Vector3 position = rotation * negDistance + target.position;
 
        transform.rotation = rotation;
        transform.position = position;
 
    }
 
}
 
    public static float ClampAngle(float angle, float min, float max)
    {
        if (angle < -360F)
            angle += 360F;
        if (angle > 360F)
            angle -= 360F;
        return Mathf.Clamp(angle, min, max);
    }
 
 
}

So you just need to figure out the angle between your forward and the cameras forward, and rotate the moveDirection by that. I assume the camera is always looking at the player?

Try adding this the line before you apply gravity?

float rotateBy = Vector2.Angle(new Vector2(Camera.main.transform.position.x, Camera.main.transform.position.z),
	                  new Vector2(transform.position.x, transform.position.z));
	    moveDirection = Quaternion.Euler(0, -rotateBy, 0)*moveDirection;

Thanks for trying, but sorry, but that did not work. :sad:

edit: But I did find what I wanted, but it rotates the character even when orbiting the x axis. I attached this script to the player added an empty game object and had the main camera parented to it. How can I edit this script to on affect the y axis?

using UnityEngine;
using System.Collections;

public class SpinCharacter : MonoBehaviour {
public Transform target;
public float speed;
void Update() {
Vector3 targetDir = target.position - transform.position;
float step = speed * Time.deltaTime;
Vector3 newDir = Vector3.RotateTowards(transform.forward, targetDir, step, 0.0F);
transform.rotation = Quaternion.LookRotation(newDir);

}
}
