2D Player Movement C#

I have a script for basic movement that works, but I want to be able to steer the players horizontal movement while midair. I also would like to be able to determine the force or the height of the jump by how long I hold the jump button.

Here's my working movement script so far:

using UnityEngine;
using System.Collections;

public class Player_movement : MonoBehaviour
    public float f_speed;
    public float f_jumpSpeed;
    public float f_gravity;
    private Vector3 v3_moveDirection = Vector3.zero;
    private CharacterController controller;

    void Awake ()
       controller = GetComponent<CharacterController>();

    void Update ()
       if (controller.isGrounded)
         v3_moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, 0);
         v3_moveDirection *= f_speed;

         if (Input.GetButton("Jump"))
                v3_moveDirection.y = f_jumpSpeed;

       v3_moveDirection.y -= f_gravity * Time.deltaTime;
        controller.Move(v3_moveDirection * Time.deltaTime);

Did you add a Character Controller?

Change your line 14 to: controller = this.GetComponent(); Put this script inside who will make the action of movement.
