Transform.left doesnt works Unity

I know this has been asked but can't figure out how to solve this.

if (this.gameObject.tag == "1Team"){
         
             unitGO.transform.position += transform.right * movementSpeed * Time.deltaTime;
 
          } else if (this.gameObject.tag == "2Team"){
                           
             unitGO.transform.position += transform.left * movementSpeed * Time.deltaTime;
 }

Unity marks in red transform.left ( Transform' does not contain a definition for 'left' ), so I dont know how to move my character to the left. I have tried using -Transform.right, Transform.right * -movementSpeed, new Vector3( - 1,0,0), unitGO.transform.position -= new Vector3(1,0,0) * movementSpeed * Time.deltaTime; and other options without getting the movement I want.

if I change the tag from the GameObject I want to move, it actually moves right, so I dont think it's anything related to attaching scripts

https://docs.unity3d.com/ScriptReference/Vector3-left.html

Any suggestions?

Thank you

While Vector3.left exists, for Transform there is only transform.right.

Which is no problem since for moving left you simply use -transform.right.

Now note that your intempts of using new Vector3 also didn't work since if you use that you move in global space along Unity's X axis .. not in local space.

Now there are multiple possible solutions:

For moving in your local space do e.g.

if (gameObject.CompareTag("1Team"))
{
    unitGO.transform.position += transform.right * movementSpeed * Time.deltaTime;
} 
else if (gameObject.CompareTag("2Team"))
{
    unitGO.transform.position -= transform.right * movementSpeed * Time.deltaTime;

    // Same as
    //unitGO.transform.position += -transform.right * movementSpeed * Time.deltaTime;
}

Or if you wan to move in Unity's global X axis then

if (gameObject.CompareTag("1Team"))
{
    unitGO.transform.position += Vector3.right * movementSpeed * Time.deltaTime;
} 
else if (gameObject.CompareTag("2Team"))
{
    unitGO.transform.position += Vector3.left * movementSpeed * Time.deltaTime;

    // Same as
    //unitGO.transform.position -= Vector3.right * movementSpeed * Time.deltaTime;
}

Or if you actually rather wanted to move along the local X axis of the object you are moving you could rather use Translate which by default uses the local space of the moved object

if (gameObject.CompareTag("1Team"))
{
    unitGO.transform.Translate(Vector3.right * movementSpeed * Time.deltaTime);
} 
else if (gameObject.CompareTag("2Team"))
{
    unitGO.transform.Translate(Vector3.left * movementSpeed * Time.deltaTime);

    // Same as
    //unitGO.transform.Translate(-Vector3.right * movementSpeed * Time.deltaTime);
}

In general rather use CompareTag instead of == to throw an error if there is a typo
