how to create 'pathfollow-no collision' code 2d?

I have tried the following: -Itween's path functions with a getkeydown code thrown in there (essentially press a button, make the char follow a jump path)

• simple physics code with raycasting and a set angle and accel.

• piecing a flurry of different Itween and raycasting tutorials into my jump code to see if I can get it.

Below I have the most successful code thus far. BUT he still doesnt follow a path, (char can move back and forth in the air).

   using UnityEngine;
   using System.Collections;
 
   public class bounding : $$anonymous$$onoBehaviour 
   {
     public string boundButton = "Fire2";
       public float jumpPower = 10.0f;
       public Animator anim;
       public bool grounded = false;
       public float $$anonymous$$JumpDelay = 0.5f;
       public Transform groundcheck;
       private float jumpTime = 10.0f;
       //private bool jumped = false;
         
       // Use this for initialization
       void Start () 
       {
           anim = gameObject.GetComponent<Animator>();
       }
     
       // Update is called once per frame
       void Update () 
       {
         grounded = Physics2D.Linecast(transform.position, groundcheck.position, 1 << Layer$$anonymous$$ask.NameToLayer ("Ground"));    
           if(jumpTime > 0)
         {
              jumpTime -= Time.deltaTime;
         }
         if(Input.GetButtonDown(boundButton))
         {
             anim.SetBool("bound",true);
             grounded = false;
             rigidbody2D.AddForce(transform.up*jumpPower);
             jumpTime = $$anonymous$$JumpDelay;
         }
         if(grounded && anim.GetBool("bound") && jumpTime <= 0) 
         {
             anim.SetBool("bound",false);
         }
     }
  }
