How to get camera to follow player 2d

Question

Hi I just made a 2d endless runner and this is the code i used to get the camera to follow the player (its in C#)

using UnityEngine; using System.Collections;

public class CameraRunnerScript : MonoBehaviour {

 public Transform player;

 void Update () 
 {
     transform.position = new Vector3 (player.position.x + 6, 0, -10); // Camera follows the player but 6 to the right
 }

}

it works fine following the player on the x axis but i was hoping someone could help me edit it so it follows the player on the y axis as well. thanks

Pretty easily achieved. Your code already demonstrates how to do it. Here's an updated version to make it a little easier for you. Just change the 'offset' values in the inspector to whatever you want. Something like (6, 6, -10) perhaps.

  public Transform player;
  public Vector3 offset;
  
  void Update () 
  {
      transform.position = new Vector3 (player.position.x + offset.x, player.position.y + offset.y, offset.z); // Camera follows the player with specified offset position
  }

Hi I'm trying to make a game of a sphere moving on 2D ground in the z-axis direction and when I try to follow the sphere with the camera it stops the movement of the ball to the right and left Here is my code for the movement: public Rigidbody rb; // Use this for initialization void Start() { rb = GetComponent(); rb.AddForce(Vector3.forward * 1, ForceMode.Impulse); }

 // Update is called once per frame
 void Update()
 {
     if (Input.GetKeyDown(KeyCode.A))
     {
         rb.AddForce(Vector3.left * 1, ForceMode.Impulse);
         rb.AddForce(Vector3.forward * 1, ForceMode.Impulse);
     }
     if (Input.GetKeyDown(KeyCode.D))
     {
         rb.AddForce(Vector3.right * 1, ForceMode.Impulse);
         rb.AddForce(Vector3.forward * 1, ForceMode.Impulse);
     }

     if (Input.GetKey(KeyCode.Space))
     {
         Vector3 dir = new Vector3(-10f, 15f, 0f);
         dir.Normalize();
         this.gameObject.GetComponent<Rigidbody>().AddForce(dir * 50);
         rb.AddForce(Vector3.forward * 1, ForceMode.Impulse);
     }

Any help how can I can solve my problem in the z-axis direction please

Please becareful using transform Directly on update . Instead use a reference to Prevent performance issues.

Try this simple code?

Public Transform Player; private Vector3 offset;

void Update () { transform.position.x = Player.transform.position.x; transform.position.y = Player.transform.position.y; transform.position.z = offset.z; }

this should work.

Hi, I am having difficulty with this as well.I am using Unity 3d 2017.1.0f3 (64 bit). I have a game object named "Player" and then as a child "Robot" (which is what is linked to animations and character controls). I made a C# script for the camera with the following code

[Code] using System.Collections; using System.Collections.Generic; using UnityEngine;

public class FollowTarget : MonoBehaviour {

 //what we are following
 public Transform target;

 //zeros out velocity
 Vector3 velocity = Vector3.zero;

 //time to follow target
 public float smoothTime = .15f;


 void fixedUpdate()
 {
     Vector3 targetPos = target.position;

     //align the camera and the target z position
     targetPos.z = transform.position.z;

     transform.position = Vector3.SmoothDamp (transform.position, targetPos, ref velocity, smoothTime);
 }

}

[/Code]

The console shows no errors, and I have the Target linked to the "Robot" game object, but the camera does not move at all. I have also tried saving the scene and closing unity then reopening it, but that did not work either. I am a little confused because I don't see a difference in the code or other parameters from the tutorial i am following along with. If it would be helpful I can provide a link to the video I am following.

Thank you in advance.
