Moving camera on only one axis.

Scripting
1

Hi guys,

I’ve been going through the forums and documentation for the past hour trying to figure this out but I’ve come to the conclusion that I’m a bit too clueless as of now to understand what people are saying.

So I decided to bite the bullet and just post.

I’m trying to make a rolling ball maze game thing, based off the “Roll a Ball” tutorial that you get with Unity.
My plan is for you to have to move a ball through a maze that is rectangular, so you are always essentially going down, so I just wanted the camera to move on the Z axis, I’ve tried a bunch of methods I’ve read but I keep doing something wrong as it doesn’t work.

This is what I am using right now, so it follows the player as it moves around, I’m sure you all could tell that anyway.

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

public class CameraController : MonoBehaviour {

public GameObject player;

private Vector3 offset;




void Start ()
{
    offset = transform.position - player.transform.position;

}
    
void LateUpdate ()
{
        transform.position = player.transform.position + offset;
      
}
}

I apologise in advance for not formatting the script in, I couldn’t figure that one out.
What would the easiest way to I guess freeze the x axis be?

Many thanks!

You could edit your post, this link can explain/show you how to post code nicely on the forums: Using code tags properly

Do you want to follow only the player’s y position … keep your x & z the same?

Thanks heaps mate, I look like a fool for missing that.

After reading over the post I can definitely see that I’ve burnt myself out today as I meant to put just move along the z axis and keep y and x where they are.

Sorry for the confusion.

no problem, so maybe you want something like this?

transform.position = new Vector3(transform.position.x, transform.position.y, player.transform.position.z) + offset;

That won’t lock to the original X and Y unless those components in offset are 0.

You’d want something like this

var pos = transform.position + (transform.position - player.transform.position);
pos.x = transform.position.x;
pos.y = transform.position.y;
transform.position = pos;

Right, I was thinking of that and neglected to comment about it.
