How do I move an object from point A to point B using a trigger?

Question

I'm basically trying to move a box from one side of the room to the other when the player enters a trigger. It seems like such a simple task, but all the solutions I've found seem extremely complicated... I'm a complete newbie to coding in general, so I'm sorry if I'm a bit dumber than you guys are used to.

The trigger is easy that is what you have to find out for yourself

Perhaps something like this? Would differ if you would use physics.

 public Transform gotoPosition;
 private Transform oldPosition;
 private float percentage = 0.0f;
 public float speed = 0.1f;

 public bool collided = false;

 void Update() {
  if (collided && percentage < 100.0f) {
   if (percentage == 0) oldPosition = transform.position;
   float percentageIncrease = Time.deltaTime * speed;
   transform.position += (gotoPosition - oldPosition) * percentageIncrease;
   percentage += percentageIncrease; 
  }
 }

 // Second script for the trigger
     public GameObject player;
     public GameObject box;
     void OnTriggerEnter(Collider collider) {
      if (collider.gameObject == player) {
       AboveScriptName script = (AboveScriptName) box.getComponent("AboveScriptName");
       script.collided = true;
      }
     }

that looks somewhat simpler than the other solutions I've seen, but I don't understand how to tell the trigger that I want THE BOX to move, not the trigger itself. Also, where do I specify the old and goto positions? Right now they don't appear to have a value...

Apply the trigger to a gameobject other than the box (and not the box as parent). Apply the script to the box, and set the gotoPosition to a (possibly empty deactivated) gameobject where you want the box to go to. $$anonymous$$ake sure there are rigidbodies attached (not necessary for the box).

This is code I wrote from the top of my head, so it might contain some errors in syntax.

These two is if you want to have that a object goes from point A to B.

Take a loot at this, maybe this will answer your question, you can also use MoveTowards
