Need help with a jumping script

Unity Engine
1

Right now I’m just playing around in Unity, and trying out different things. I’m not very good with scripting (yet), so i need help to make my character jump.

The idea is, that the longer you press space (or hold down on a touch screen) the higher the character should jump (with no limits). Holding down longer should make the jump higher.

If anyone could help me making a such script it would be highly appriciated!

Here’s something to get you started:

using UnityEngine;
using System.Collections;

public class Jump : MonoBehaviour
{
    private bool jumping;
    void FixedUpdate()
    {
        // Are we standing on something, so we can begin jumping?
        bool grounded = Physics2D.Raycast(
            (Vector2)transform.position - Vector2.up * .25f, // .25f is the distance from the pivot point, where we should start looking for the floor
            -Vector2.up,
            0.1f // How far should we look
            );

        // Are we standing on something or are we already jumping
        if ((grounded || jumping) && Input.GetKey(KeyCode.Space))
        {
            jumping = true;
            rigidbody2D.AddForce(Vector2.up * 25);

            if (rigidbody2D.velocity.y > 200)
            {
                Vector2 v = rigidbody2D.velocity;
                v.y = 200;
                rigidbody2D.velocity = v;
            }
        }
        else
        {
            // If we let go of the jumpbutton, we're not jumping anymore
            jumping = false;
        }
    }
}
