A field initializer cannot reference the non-static field, method, or property 'Component.transform'

Happy weekend, all!

I’m trying to use a Vector3 to copy the x and z euler angles, then change the euler y angle to -180, for the 2D object attached to the script and all of its children. By doing so I hope to flip the objects across the y axis, making them face the opposite direction— left.
I got the error in the title, however. Does anyone know how to make this work as intended without errors? I appreciate any insight, even if you’re not too sure.

The issue has only occurred after attempting to apply “transform.eulerAngles = FaceLeft” on line 72.
The issue is on line 19, character 44, and character 80— Unity doesn’t like the transform.eulerAngles.x & z.
Here’s my code:

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

public class CharacterMovement : MonoBehaviour
{
    private void Start()
    {
        _rigidbody = GetComponent<Rigidbody2D>();
    }

    //This is the movement speed
    private static float MoveForce = 10;
    private static float JumpForce = 8;
    public Vector2 HorizontalVelocity = new Vector2(MoveForce,0);
    public Vector2 VerticalVelocity = new Vector2(0, JumpForce);

    //This is the rotation for facing a sprite left.
    private Vector3 FaceLeft = new Vector3(transform.localeulerAngles.x, -180, transform.localeulerAngles.z);
 
 
    // </>
//This is for the TpToSpawn method
    public Vector3 SpawnPosition = new Vector3(-2, -3, 0);
    public Vector4 Upright = new Vector4(0, 0, 0);
// </>
    private Rigidbody2D _rigidbody;

 
 



 
    private void Update()
    {
        //Move Player to spawn position, reset their velocity, and make them upright
        //If they fall off the map
     
            if(transform.position.y < -5)
            {
                Debug.Log("The Player should be respawning!");
                _rigidbody.velocity = new Vector2(0,0);
                transform.position = SpawnPosition;
                transform.eulerAngles = Upright;
            }
     
        //This allows horizontal movement

        if(Input.GetButton("Right"))
        {
            _rigidbody.AddForce(HorizontalVelocity * Time.deltaTime, ForceMode2D.Impulse);
        }

        if(Input.GetButton("Left"))
        {
            _rigidbody.AddForce(-HorizontalVelocity * Time.deltaTime, ForceMode2D.Impulse);
        }
     
        //This allows for jumping if the character presses the jump button
        //and their vertical velocity is less than 0.001 units/s
        if(Input.GetButtonDown("Jump") && Mathf.Abs(_rigidbody.velocity.y) < 0.001f)
        {
            //Add an Impulse force called JumpForce
            _rigidbody.AddForce(VerticalVelocity, ForceMode2D.Impulse);
        }

        //Makes the character face left when they move left
        //changing the euler angles to the "FaceLeft" Vector3
        if(Input.GetButtonDown("Left"))
        {
            transform.eulerAngles = FaceLeft;
        }

    
    }
}

You can’t call functions in field initializers like you’re doing in line 19.

You can convert that variable into a getter pretty trivially and then it should work.

NOTE: the “function” you’re calling is transform.localeulerAngles, which is a getter in itself.

ALSO: transform.localeulerAngles is misspelled; the Euler is capitalized.

Thank you very much! I’m glad you told me transform.localEulerAngles is a getter; I ended up deleting line 19 altogether and using this on line 80 INSIDE THE UPDATE METHOD which I previously failed to realize was the reason for that error:

transform.eulerAngles = new Vector3(transform.eulerAngles.x, -180, transform.eulerAngles.z)
