Finding name of gameobject that entered a trigger

I'm trying to create a script that has a game object follow another game object that enters the collider. In order to do so, I've tried referring to the object that entered the trigger as other.gameObject, so I can get its transform component, but the Unity doesn't understand what I'm trying to do.

In short, I'm trying to get the component of a game object that enters a trigger without having to refer to its name. Is it possible to do this, or is it that I just haven't found how to do this?

Thanks.

Here's what I have so far: Initialized variables: private bool playerDetected = false; private GameObject Target;

 private void OnTriggerEnter(Collider other)
 {
    if (other.tag == "PlayerCharacter")
    {
        playerDetected = true;
        Target = other.gameObject.GetComponent<Transform>();
    }
 }
