As the title says I am trying to make the camera follow the player in a 2D platformer I am making, however it comes up with errors in this script, if any of you guys could help, I’m sorta new to Unity and c#. Here is my code:

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

public class CameraFollower : MonoBehaviour 
{

	private Transform myTransform;
	public Transform PlayerTransform;

	private void Awake () 
	{
		myTransform = GetComponent<Transform> ();
	}

	void LateUpdate () 
	{
		if (PlayerTransform.position.x <= .685449) {
			myTransform.position.x = 0.685449;
		} 
		else if (PlayerTransform.position.x >= 9.31455) 
		{
			myTransform.position.x = 9.31455;
		} 
		else 
		{
			myTransform.position.x = PlayerTransform.position.x;
		}
	}
}

I think the problem is that transform.position is a c# property . This means you cant modify x in that way. (think of property as functions without the () to call them)

The way you could update then position is to assign it to a variable first, then modify it, and finally set the position equal to the new position. Example:

var newPosition = transform.position;

// if statements here
newPosition.x = PlayerTransform.position.x;

transform.position = newPosition;

and of course add your if statements back in the middle as well.

Edit:

you can still do checks on properties, so if (PlayerTransform.position.x <= .685449) will works.
