Cannot modify a value type return value of `UnityEngine.Transform.localRotation'. Consider storing the value in a temporary variable. Help

My problem is this line transform.localRotation.eulerAngles = new Vector3 (0.0f, curY, 0.0f); And its not working. Its from java source and i want it to be converted to C#.

When you request localRotation, C# gives you a copy of it. Changes made to the copy are ignored by the original. That’s because Quaternion is a struct type.

You can fix this by declaring a temporary variable:

Quaternion rot = transform.localRotation;
rot.eulerAngles = new Vector3 (0.0f, curY, 0.0f);
transform.localRotation = rot;

Or, you can just assign the value directly:

transform.localRotation = Quaternion.Euler(0.0f, curY, 0.0f);

You’ll see this same behavior with vectors (such as transform.position).
