[SOLVED]Moving object in the direction of camera view

Unity Engine
1

Well basically I would like to move an object which has attached camera - it can rotate, but how do I make it move in the direction where the object camera points to?
I just started learning Unity :sweat_smile:

A quick technique is to do this:

transform.position = transform.position + Camera.main.transform.forward * distance * Time.deltaTime;

Basically, it says move the object this script is on in the direction the camera is facing distance units per second. You’ll have to declare a global variable for distance like:

var distance : float = 5;

though. Time.deltaTime is the variable that makes sure movements are done per second if done inside function Update() or once per frame.

I found a lot of complicated answers to this question, and then found this. Thanks Gargerath Sunman!

Thank you for the tip! It’s awesome, but I am facing a problem here, my character walks over a planet using an orbital camera that turns arround him, the problem is that if I look from above the player it wolks into the planet, since the gravity is very low, if I walk backwards, while looking from the very top, it flyes awar from the planet

camera rotate up and down move togrther in unity

Hi, may I ask how can I do the same with rigidbody? To make matters more complicated, my camera is also able to tilt downwards / upwards, but I still want my rigidbody to move parallel to the ground. How can I do so?

I currently am using a joystick to control the velocity of a cube like so:

void Update()
        {
            var rigidbody = GetComponent<Rigidbody>();
            rigidbody.velocity = new Vector3(joystick.Horizontal * 3f,
                                             rigidbody.velocity.y,
                                             joystick.Vertical * 3f);
        }

Thank you so much in advance!

A question about this is this line of code ‘transform.position = transform.position + Camera.main.transform.forward * distance * Time.deltaTime;’ possible to be made with adding in forces

How can I move at any angle to the camera, not just forward?

This did not work at all. I am trying to make a 3d fps and my character started moving on its own. It went in the opposite direction as the camera and sunk into the ground.

for any direction you can combine forward and right

private float _dragObjectSpeed = 0.2f;
transform.position = transform.position + Camera.main.transform.forward * Input.GetAxis("Mouse Y") * _dragObjectSpeed + Camera.main.transform.right * Input.GetAxis("Mouse X") * _dragObjectSpeed;

when my player looks up, the player jumps, how do i fix that?

change the value of the Y scale on the movement to 0.0f

jupitr just put the line under the if statement that specifies what happens when you press w

but why we use distance?

I am building a 360 photo sphere. When the Up Arrow is pressed, I want the camera to move from the center of the sphere closer to the edge and stop at a set distance. Then when the Up Arrow is released, I want the camera to return to the center of the sphere.
I am having trouble adapting this script to meet that need.

I have this script attached to the camera. It works when I press up (although very slow). how can i make it return to the origin position when I let go of the up arrow?

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

public class TrackPosition : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKey(KeyCode.UpArrow))
        {
            transform.position += Camera.main.transform.forward * Time.deltaTime;
        }
    }
}

use an else if statement. that should work. as for which else if statement you need to use? I don’t know. someone else on this tread might know though

Hi! Can you please tell me the solution for this, I am facing the same problem.

19

soo… i cant seem to find anything, so can anyone help with my code? its supposed to move with the camera direction, but it takes the same “Forward” every time.

my code:

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

public class move : MonoBehaviour
{
public float speed = 1000f;
public Rigidbody rb;
private bool Grounded;
public float jump;

void OnCollisionEnter(Collision col)
{
if (col.gameObject.name == “Ground”)
{
Grounded = true;
}
}
void Update()
{
if (Input.GetKey(KeyCode.RightArrow) || Input.GetKey(KeyCode.D))
{
transform.Rotate(0.0f, 2.0f, 0.0f);
}
if (Input.GetKey(KeyCode.LeftArrow) || Input.GetKey(KeyCode.A))
{
transform.Rotate(0.0f, -2.0f, 0.0f);
}
if (Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W))
{
rb.AddForce(Vector3.forward * speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.DownArrow) || Input.GetKey(KeyCode.S))
{
rb.AddForce(Vector3.back * speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.Space) && Grounded == true)
{
rb.AddForce(Vector2.up * jump * Time.deltaTime);
Grounded = false;
}

}
}

thanks!
