move an object within unity code example

Example 1: how to make an object move in unity

Vector3 input = new Vector3 (Input.GetAxis("Horizontal"), 0 , Input.GetAxis("Vertical");
Vector3 dir = input.normalized;
Vecotr3 vel = dir * speed * Time.deltaTime;

transform.Translate(vel);

Example 2: how to move towards an object unity

//This will work for 2d or 3d platforms
//Make sure to call in Update or else it wont work
Vector3.MoveTowards(transform.position, taretPos, Qiaternion.identiy)
