[SOLVED] Cannot modify a value type return value of `UnityEngine.Transform.rotation'

Unity Engine

I’m not sure why the code below isn’t working as I am using a temp variable. The error is: error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.rotation’. Consider storing the value in a temporary variable

Note that this is just a simplified version of my code, I am not applying the rotation in update in the proper code, but this illustrates the problem.

public class test : MonoBehaviour {

    Transform _this_transform;

    void Start () {

        _this_transform = GetComponent<Transform> ();
       
    }
   

    void Update () {

        Vector3 _current_rotation = _this_transform.rotation.eulerAngles;

        _current_rotation.x = 0f;
        _current_rotation.y = 180f;
        _current_rotation.z = 0f;


        _this_transform.rotation.eulerAngles = _current_rotation;
   
    }

}

Any advice appreciated, thanks.

You can convert your Vector3 into a Quaternion before assigning it to your transform like

Quaternion newRot = Quaternion.Euler (_current_rotation);
_this_transform.rotation = newRot;

Thanks Karrzun that works fine.
