Question How do I make the player move in the same direction that the camera is facing in unity

This is my movement script.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerMovement : MonoBehaviour
6. {
7.     public Rigidbody rb;
8.  
9.     bool isGrounded = true;
10.     public float distToGround = 1f;
11.  
12.     public float forwardForce = 500f;
13.     public float sidewaysForce = 500f;
14.     public float jumpForce = 500f;
15.     public float distance = 5;
16.  
17.     void FixedUpdate()
18.     {
19.         var look = new Vector3(Camera.main.transform.forward.x, transform.position.y, Camera.main.transform.forward.z);
20.  
21.         if (Input.GetKey("w"))
22.         {
23.             rb.AddForce(0, 0, forwardForce * Time.deltaTime);
24.         }
25.  
26.         if (Input.GetKey("s"))
27.         {
28.             rb.AddForce(0, 0, -forwardForce * Time.deltaTime);
29.         }
30.  
31.         if (Input.GetKey("d"))
32.         {
33.             rb.AddForce(sidewaysForce * Time.deltaTime, 0, 0);
34.         }
35.  
36.         if (Input.GetKey("a"))
37.         {
38.             rb.AddForce(-sidewaysForce * Time.deltaTime, 0, 0);
39.         }
40.  
41.         if (Input.GetKey("space") && isGrounded)
42.         {
43.             rb.AddForce(0, jumpForce * Time.deltaTime, 0);
44.         }
45.  
46.         GroundCheck();
47.     }
48.  
49.     void GroundCheck()
50.     {
51.         if (Physics.Raycast(transform.position, Vector3.down, distToGround + 0.1f))
52.         {
53.             isGrounded = true;
54.         }
55.         else
56.         {
57.             isGrounded = false;
58.         }
59.     }
60. }

This is my camera look script

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class LookAround : MonoBehaviour
6. {
7.     public GameObject player;
8.  
9.     public float mouseSensitivity = 100.0f;
10.     public float clampAngle = 80.0f;
11.  
12.     private float rotationY = 0.0f;
13.     private float rotationX = 0.0f;
14.  
15.     private float distance = 0.0f;
16.  
17.     void Start()
18.     {
19.         Vector3 rotation = transform.localRotation.eulerAngles;
20.         rotationY = rotation.y;
21.         rotationX = rotation.x;
22.     }
23.  
24.     void Update()
25.     {
26.         float mouseX = Input.GetAxis("Mouse X");
27.         float mouseY = -Input.GetAxis("Mouse Y");
28.  
29.         rotationY += mouseX * mouseSensitivity * Time.deltaTime;
30.         rotationX += mouseY * mouseSensitivity * Time.deltaTime;
31.  
32.         rotationX = Mathf.Clamp(rotationX, -clampAngle, clampAngle);
33.  
34.         Quaternion localRotation = Quaternion.Euler(rotationX, rotationY, 0.0f);
35.         transform.rotation = localRotation;
36.     }
37. }

 

do this instead,
private GameObject cam;
public float speed;
void Start()
{
cam = Camera.main;
}
then in your movement put this
rb.AddForce(cam.transform.forward * Speed * Time.deltaTime);

 

I just added this to my proximity_buttons project repository yesterday.

Look for the

DemoCameraRotatedControls.unity

scene.

proximity_buttons is presently hosted at these locations:

https://bitbucket.org/kurtdekker/proximity_buttons

https://github.com/kurtdekker/proximity_buttons

https://gitlab.com/kurtdekker/proximity_buttons

https://sourceforge.net/projects/proximity-buttons/

 

on the line cam = Camera.main; I get an error saying cannot implicitly convert type 'UnityEngine.Camera' to UnityEngine.GameObject'.I tried deleting the line and replacing the cam in the line rb.AddForce(cam.transform.forward * Speed * Time.deltaTime); with Camera.main, but it still didn't work.

 

I think it's just a typo in Elliot's code. This is probably what he meant:

Code (csharp):

1. cam = Camera.main.gameObject;

The reason is,

Camera.main

is a shortcut to the camera tagged with "Main Camera", and he was trying to assign the

Camera

component to a

GameObject

variable (in this case

cam

). Easy mistake.

Meanwhile, the proximity_buttons demo I liked above does all the things out-of-box, so you're welcome to take a look at it.

 

ok thanks, I want to learn it by experience instead of just copying. I checked out your code and it was great.

and also it still didn't work.

 

My code or the other snippet I responded to? I haven't studied how Elliot's trying to do it, as like I said I just do it "my way."

Let me know if my code is misbehaving.

 

Elliots code

 

I didn't write the code in the editor but thats what I meant, also for me the code i put, it would usually work so its strange that it doesnt work for you

 

yeah, I don't know either, but do you know any other way?

 

Yeah, i figured out another way that hasn't been done before i think. I added another camera that only rotated on the x-axis, and used that camera instead of the main camera for this line of code transform.position = transform.position + xCam.transform.forward * distance * Time.deltaTime;
this is what i used to make the camera rotate

Code (CSharp):

1. public class Cam2FollowCam1 : MonoBehaviour
2. {
3.     public GameObject player;
4.  
5.     public float mouseSensitivity = 100.0f;
6.     public float clampAngle = 80.0f;
7.  
8.     private float rotationY = 0.0f;
9.     private float rotationX = 0.0f;
10.  
11.     private float distance = 0.0f;
12.  
13.     void Start()
14.     {
15.         //Remember to make a look script that only looks left and right for a new camera object.
16.  
17.         Vector3 rotation = transform.localRotation.eulerAngles;
18.         rotationY = rotation.y;
19.         rotationX = rotation.x;
20.     }
21.  
22.     void Update()
23.     {
24.         float mouseX = Input.GetAxis("Mouse X");
25.         float mouseY = -Input.GetAxis("Mouse Y");
26.  
27.         rotationY += mouseX * mouseSensitivity * Time.deltaTime;
28.         rotationX += mouseY * mouseSensitivity * Time.deltaTime;
29.  
30.         rotationX = Mathf.Clamp(rotationX, -clampAngle, clampAngle);
31.  
32.         //Quaternion localRotation = Quaternion.Euler(rotationX, rotationY, 0.0f);
33.         Quaternion localRotation = Quaternion.Euler(0.0f, rotationY, 0.0f);
34.         transform.rotation = localRotation;
35.     }
36. }
